    I used to use this method of corner joint before I started using epoxy resin adhesive. I got lazy and tried "pinning" the corners with metal pegs after assembly with the epoxy adhesive, sort of as a "belt and suspenders" approach to make sure everything was fastened securely. It seems to produce a strong joint and I'm not even sure the pegs are necessary, since a lot of the rigidity of the structure comes from the panes set in the grooves.
     
    The one problem I've yet to devise an easy solution to is cleaning the glass on the inside of a case that's taller than the length of my arm! I've tried folding a sponge over the end of a stick and wrapping the sponge in terrycloth toweling held in place with duct tape. It's still tedious business. The next case I build, I will wear clean nitrile gloves in the hope of avoiding a fingerprint somewhere deep on the inside of the glass!

    There is at least one article on building cases in one of the Shipmodeler's Shop Notes volumes and perhaps a few posts about case making on the forum, but the search feature didn't help any when I looked for them. It's a simple enough project to make a case, although it helps to have three arms! A decent table saw is a must and you'll need to have a way of making very exactly accurate 45 degree angle cuts. This is where your Jim Saw will really come in handy!  A picture framer's 45 degree corner clamp is also very handy, although one can build their own jig for this purpose easily enough.
     
    I've found the best-priced glass can be sourced from places like Michael's that do custom framing. Ask them to cut to the exact dimensions you specify and buy the picture framing glass with the UV-blocking filtering in it. I've also used simple window glass, which is a bit cheaper, but I've found a glazer's shop may not cut to the exact measurements you request and may not have the thinner glass you'd likely prefer.  
     
    Construction is pretty simple and any article on building cases will give you the details. You can pick whatever method you prefer. I like glass because it doesn't scratch like the plastics can and it's less expensive. It's easier to clean, too.  I've found that you can't build a glued box plexiglas case unless you are a pro. They use special proprietary adhesives that dry to an invisible weld at the corners and if your adhesive (I've tried CA) goes anywhere that you don't want it, you'll have a mess that is relatively impossible to buff out unless you are using the professional proprietary adhesive which is only sold to licensees, I believe. If you prefer plastic, you can always build a wood frame case and glaze it with plastic.  Plastic out-gasses and that troubles me in terms of archival quality. Others' mileage varies in that respect, of course.
     
    One can buy case kits, but they are expensive and the size selection is limited. Purchasing a professionally built case has always been prohibitively expensive in my estimation, although I have the tools to do it in house myself, so I'm biased in that respect. Most of the case kits on the market do not include the glass or plastic. Shipping the fragile built case from the manufacturer is quite expensive, as well. I expect the special handling and insurance is costly.
     
    After trying a number of construction methods, I've settled on what I've found to be the most simple. I make two rectangles with 45 degree mitered corners. these define the shape of the top and bottom of the case frame. The top rectangle has a saw kerf cut into the inside sides of it, as well as on the bottom sides of it. (A table saw blade kerf just matches thickness of the glass I use. It should be a tight fit.) The top rectangle is assembled with the glass held in place in the saw kerfs. The corners are glued with thickened epoxy adhesive and allowed to set. Diagonal holes are then (carefully) drilled at right angles to the joints and a dowel or metal pin (or two, depending on the size of the case) is inserted into the hole(s) at each corner and glued with epoxy or CA. The bottom rectangle is assembled in the same fashion, but without the glass, of course, for which reason it will only need saw kerfs on its top sides. Then four posts are cut and saw kerfs run on the two inside sides of each post. (All this kerf cutting will take careful measurements to ensure the kerfs on the posts will be in line with the kerfs in the top and base.) The entire case is then assembled with the edges of its glass sides being captured by the saw kerfs in the top and bottom rectangles and the side posts and the side posts are glued with epoxy to the top and bottom rectangles. (Here again, fitting is critical. A little bit of extra depth in the saw kerfs is helpful. Do not force the glass panes into the kerfs. Don't ask me how I know this!) When this epoxy is cured, again carefully, drill one or two holes in the top and bottom rectangles at each corner and insert a dowel or metal pin cemented with epoxy or CA. The holes for the metal pins can then be filled with a bit of furniture refinisher's wax or putty and will be virtually invisible. If you use dowels, they can be sanded flush.
     
    This wooden framed glass box is the top of the case. A base, upon which the model will rest, must be built to accept the "box" cover when it is placed over it. A rabet in the base board edge secures the case over the base and keeps it from slipping around. If one desires, holes can be drilled in the edges of the frame of the glass box and through into the edges of the baseboard rabet and a nail, brass escutcheon pin, or other unobtrusive fastener provided to slide into the holes with a "slip fit." these will prevent a disaster from occurring if someone attempts to lift up the case by the "box" instead of the baseboard, thinking it's all attached and whacks the model with the box! This is particularly relevant to small models that hamfisted cleaning ladies seem to think the can just throw around when they are dusting! 
     
    It is important to provide a means for air circulation in a model case. Otherwise, an acidic atmosphere can be trapped in the case environment and cause deterioration of the model. The acid out-gasses from various sources within the case environment, including PVA adhesives and without air circulation, can reach destructive levels over time. Only a very small hole is required. A space of an eighth of an inch between the side of the baseboard rabet and the box bottom rectangle and a space of and eighth of an inch between the baseboard and the bottom of of the "box," provided by something like those adhesive felt "buttons" they sell for putting on the lower back edges of picture frames so they don't mark up the walls should be sufficient. The "rule of thumb" is that there should be one square inch of "hole" in a case for every one cubic yard of a case's interior volume, so it doesn't take much to provide enough circulation. An alternate method of providing ventilation is to make the base rectangle higher than the size of the rest of the framing rails and drill a few ventilation holes through the back of it. This "heavier" base rectangle side can also be more aesthetically pleasing, particularly if the baseboard plinth upon which the model is mounted is raised up a bit. See: Nautical Research Guild - Article - Ephemeral Materials in Ship Models (thenrg.org) for more details on preventing acid deterioration in ship model cases.
     
    So, there you have it. It's not rocket science, but it does take care and accurate measurements and cutting. Building a case for a 36" model yourself can easily save you several hundred bucks!

    Quality linen thread isn't being manufactured as much as it used to be and is indeed difficult to obtain today. However, interestingly, hemp is making a significant comeback in the fiber industries and, for all intents and purposes, is nearly indistinguishable from linen (flax) in it's properties. Hemp thread is now being produced and sold, and although it hasn't become widely available, it's becoming moreso. Look for it online. Amazon.com: Coats & Clark Extra Strong Upholstery Thread, 150-Yard, Hemp
     
    Given that linen is unavailable, Chuck reports that at least one major museum has gone over to Gutermann's Mara polyester which they feel has acceptable archival qualities for use in rigging ship models. See: Gutermann Mara 100 Poly Wrapped Poly Core Thread - Tex 30 - WAWAK Sewing Supplies 
     
    Anything other than these two aren't isn't being widely considered better for ship model rigging. Check Chuck's rope-making posts in the "More" section in the forum masthead. There are lots of discussions regarding thread to use for ropemaking. In any event, all the custom-made cordage for modeling is better by a long shot than anything any of the kit manufacturers I've seen are putting in their kits.

    And the hobby-oriented retailers frequently have lower-quality less expensive things which, if you search on line, you can find in much higher quality versions for sometimes even lower prices.
     
    Consider these online retailers for "ideas." Note also that if you sign up for the email advertisements and catalogs, they are frequently running quite deep discount sales:     Micro-Mark - The Small Tools Specialists ⚙️ (micromark.com)    Model Expo - Historically accurate wooden model kits made in the USA (modelexpo-online.com)

Prices are often cut drastically, especially around inventory tax time.)
     
    Also, check out eBay for any of the things you are looking for. There are often close-outs and tons of Asian knockoffs (buyer beware on those, though.) The Used dental and medical tools on eBay are often great bargains, particularly for tweezers, forceps, dental burs, scalpels and such. One surprisingly fertile area to mine on eBay is the manicurists' supplies. Small paintbrushes for painting women's nails can be had at amazingly low prices compared to the art supply stores. The same goes for abrasive boards and rotary tools. The drafting instrument section on eBay is also excellent for finding useful used drawing instruments such as scales, straight edges, ruling pens, and proportional dividers, often for pennies on the dollar for what they originally cost. While eBay is full of junk, if you know what you're looking for, there are great bargains to be had. I just scored a brand new Buffalo Model 16 dental lab engine and handpiece, a total retail value of close to $1,000.00 for seventy-five bucks on eBay. It was listed as a "steampunk decor item" with the caveat that it was not operational. Knowing they were still in production, I took a chance it might be repairable. It turned out the motor brushes, which are shipped uninstalled with the new units, were never installed and lost, and the belt and one of the pulley wheels was missing. Buffalo is shipping me the missing parts for $45.00. Life is good!

    As you may have guessed, I like to shop for tools like Imelda Marcos likes to shop for shoes.  One thing I've learned, though, is not to buy a tool until you need it and then, unless it's something relatively disposable, buy the best quality tool you can afford, and never pass up a good deal. You usually have to buy a cheap tool twice. A good tool should last a lifetime, or close to it and they are a joy to behold. It's certainly true that many a model has been built with the most basic of tools and very few of them, so don't let collecting tools get in the way of your modeling. Just start picking them up as you go and before you know it you'll have more tools than time to use them.

    I’d like to add my two cents worth to Bob’s excellent post above.  Although you have decided to buy a kit, this might be interesting to others wanting to build one from scratch.
     
    Tools:  At least one right angle picture frame clamp is a must.  Also a table saw for ripping stock and cutting grooves.  I have a 35+ year old set of Sears molding cutters that are excellent for cutting the decorative edge on the prepared stock.  If you are interested in using a set of these i’d be happy to post a photo of my setup.
     
    Materials:  I personally like American Black Walnut as it is easy to finish and I have a good supply.  Although Mahogany is a traditional boatbuilding material, the stuff sold today called Mahogany is nasty stuff.  If you can find and are willing to pay for true Honduras Mahogany it is a joy to work with.  Teak can make a nice case and is also easy to work with.  I find cherry to be hard to finish.
     
    Like Bob, I like the thickened epoxy glues.  A little poster paint powder can be  added to the mix to color it like the wood that you are using.
     
    For the last case that I built, I bought glass from our local Ace Hardware.  They cut it accurately.  Since I don’t live in sunny California,😜 I have not used UV resistant glass.
     
    The rough sketch below shows my system.  The key is embedding the upright posts into notches cut into the mitred corner joints of the base.  When glued with epoxy this results in a solid three dimensional joint.  When making these corner joints, I use right angle triangles made from 1/8th thick plywood set into the grooves to ensure that everything is square.  Wax the edges of the ply!

    This is just a display stand. It's the same one that's included with their HMS Victory kit. Nothing special, but it's made for models with a keel that's flat and parallel to the waterline, as the model is supposed to rest directly on the stand. The only downside I see is that the edge of the baseboard is visible, and it's plywood. So, you see all the ply layers.
     
    Also, it won't serve as the base for an acrylic case, unless the case is just a 5-sided box and you're using it as a simple dust cover.

    If you don't have the tools to make a case there are places that will make them for you.  Some will make the box and you make the base.  If you have a table saw great, if you don't, not a problem.  Make the base board (lumber stores will cut to size for you) and use small strips of wood to form the grooves in which the box will sit.   It is actually easier to do it this way.  Set the box on the base board and glue the outboard strips in place..... perfect fit every time.   Then remove the box and glue the inboard strips leaving the gap to match the thickness of the box walls.    
     
    Do pay attention to have some kind of air holes as explained above by Bob.  Tiny openings are best and/or fill the openings with something like plastic wool or other non-rusting material to keep out the beasts but will let the air in.   Even a 1/8" hole will let the spiders in.

    UV protection or not, it is best not leave the model where it is exposed to direct sun light.

    There is at least one article on building cases in one of the Shipmodeler's Shop Notes volumes and perhaps a few posts about case making on the forum, but the search feature didn't help any when I looked for them. It's a simple enough project to make a case, although it helps to have three arms! A decent table saw is a must and you'll need to have a way of making very exactly accurate 45 degree angle cuts. This is where your Jim Saw will really come in handy!  A picture framer's 45 degree corner clamp is also very handy, although one can build their own jig for this purpose easily enough.
     
    I've found the best-priced glass can be sourced from places like Michael's that do custom framing. Ask them to cut to the exact dimensions you specify and buy the picture framing glass with the UV-blocking filtering in it. I've also used simple window glass, which is a bit cheaper, but I've found a glazer's shop may not cut to the exact measurements you request and may not have the thinner glass you'd likely prefer.  
     
    Construction is pretty simple and any article on building cases will give you the details. You can pick whatever method you prefer. I like glass because it doesn't scratch like the plastics can and it's less expensive. It's easier to clean, too.  I've found that you can't build a glued box plexiglas case unless you are a pro. They use special proprietary adhesives that dry to an invisible weld at the corners and if your adhesive (I've tried CA) goes anywhere that you don't want it, you'll have a mess that is relatively impossible to buff out unless you are using the professional proprietary adhesive which is only sold to licensees, I believe. If you prefer plastic, you can always build a wood frame case and glaze it with plastic.  Plastic out-gasses and that troubles me in terms of archival quality. Others' mileage varies in that respect, of course.
     
    One can buy case kits, but they are expensive and the size selection is limited. Purchasing a professionally built case has always been prohibitively expensive in my estimation, although I have the tools to do it in house myself, so I'm biased in that respect. Most of the case kits on the market do not include the glass or plastic. Shipping the fragile built case from the manufacturer is quite expensive, as well. I expect the special handling and insurance is costly.
     
    After trying a number of construction methods, I've settled on what I've found to be the most simple. I make two rectangles with 45 degree mitered corners. these define the shape of the top and bottom of the case frame. The top rectangle has a saw kerf cut into the inside sides of it, as well as on the bottom sides of it. (A table saw blade kerf just matches thickness of the glass I use. It should be a tight fit.) The top rectangle is assembled with the glass held in place in the saw kerfs. The corners are glued with thickened epoxy adhesive and allowed to set. Diagonal holes are then (carefully) drilled at right angles to the joints and a dowel or metal pin (or two, depending on the size of the case) is inserted into the hole(s) at each corner and glued with epoxy or CA. The bottom rectangle is assembled in the same fashion, but without the glass, of course, for which reason it will only need saw kerfs on its top sides. Then four posts are cut and saw kerfs run on the two inside sides of each post. (All this kerf cutting will take careful measurements to ensure the kerfs on the posts will be in line with the kerfs in the top and base.) The entire case is then assembled with the edges of its glass sides being captured by the saw kerfs in the top and bottom rectangles and the side posts and the side posts are glued with epoxy to the top and bottom rectangles. (Here again, fitting is critical. A little bit of extra depth in the saw kerfs is helpful. Do not force the glass panes into the kerfs. Don't ask me how I know this!) When this epoxy is cured, again carefully, drill one or two holes in the top and bottom rectangles at each corner and insert a dowel or metal pin cemented with epoxy or CA. The holes for the metal pins can then be filled with a bit of furniture refinisher's wax or putty and will be virtually invisible. If you use dowels, they can be sanded flush.
     
    This wooden framed glass box is the top of the case. A base, upon which the model will rest, must be built to accept the "box" cover when it is placed over it. A rabet in the base board edge secures the case over the base and keeps it from slipping around. If one desires, holes can be drilled in the edges of the frame of the glass box and through into the edges of the baseboard rabet and a nail, brass escutcheon pin, or other unobtrusive fastener provided to slide into the holes with a "slip fit." these will prevent a disaster from occurring if someone attempts to lift up the case by the "box" instead of the baseboard, thinking it's all attached and whacks the model with the box! This is particularly relevant to small models that hamfisted cleaning ladies seem to think the can just throw around when they are dusting! 
     
    It is important to provide a means for air circulation in a model case. Otherwise, an acidic atmosphere can be trapped in the case environment and cause deterioration of the model. The acid out-gasses from various sources within the case environment, including PVA adhesives and without air circulation, can reach destructive levels over time. Only a very small hole is required. A space of an eighth of an inch between the side of the baseboard rabet and the box bottom rectangle and a space of and eighth of an inch between the baseboard and the bottom of of the "box," provided by something like those adhesive felt "buttons" they sell for putting on the lower back edges of picture frames so they don't mark up the walls should be sufficient. The "rule of thumb" is that there should be one square inch of "hole" in a case for every one cubic yard of a case's interior volume, so it doesn't take much to provide enough circulation. An alternate method of providing ventilation is to make the base rectangle higher than the size of the rest of the framing rails and drill a few ventilation holes through the back of it. This "heavier" base rectangle side can also be more aesthetically pleasing, particularly if the baseboard plinth upon which the model is mounted is raised up a bit. See: Nautical Research Guild - Article - Ephemeral Materials in Ship Models (thenrg.org) for more details on preventing acid deterioration in ship model cases.
     
    So, there you have it. It's not rocket science, but it does take care and accurate measurements and cutting. Building a case for a 36" model yourself can easily save you several hundred bucks!

    And the hobby-oriented retailers frequently have lower-quality less expensive things which, if you search on line, you can find in much higher quality versions for sometimes even lower prices.
     
    Consider these online retailers for "ideas." Note also that if you sign up for the email advertisements and catalogs, they are frequently running quite deep discount sales:     Micro-Mark - The Small Tools Specialists ⚙️ (micromark.com)    Model Expo - Historically accurate wooden model kits made in the USA (modelexpo-online.com)
     
    Check out jewelers' supply houses like: OttoFrei.com - Jewelry Tools & Findings Since 1930  Rio Grande Jewelry Supply  Jewelry Tools | Jewelry Making Supplies | Wholesaler | Stuller  Esslinger Watchmakers Tools and Watch Parts  Contenti Jewelry Making Tools | Contenti (Watch for the sales. Prices are often cut drastically, especially around inventory tax time.)
     
    Also, check out eBay for any of the things you are looking for. There are often close-outs and tons of Asian knockoffs (buyer beware on those, though.) The Used dental and medical tools on eBay are often great bargains, particularly for tweezers, forceps, dental burs, scalpels and such. One surprisingly fertile area to mine on eBay is the manicurists' supplies. Small paintbrushes for painting women's nails can be had at amazingly low prices compared to the art supply stores. The same goes for abrasive boards and rotary tools. The drafting instrument section on eBay is also excellent for finding useful used drawing instruments such as scales, straight edges, ruling pens, and proportional dividers, often for pennies on the dollar for what they originally cost. While eBay is full of junk, if you know what you're looking for, there are great bargains to be had. I just scored a brand new Buffalo Model 16 dental lab engine and handpiece, a total retail value of close to $1,000.00 for seventy-five bucks on eBay. It was listed as a "steampunk decor item" with the caveat that it was not operational. Knowing they were still in production, I took a chance it might be repairable. It turned out the motor brushes, which are shipped uninstalled with the new units, were never installed and lost, and the belt and one of the pulley wheels was missing. Buffalo is shipping me the missing parts for $45.00. Life is good!

    As you may have guessed, I like to shop for tools like Imelda Marcos likes to shop for shoes.  One thing I've learned, though, is not to buy a tool until you need it and then, unless it's something relatively disposable, buy the best quality tool you can afford, and never pass up a good deal. You usually have to buy a cheap tool twice. A good tool should last a lifetime, or close to it and they are a joy to behold. It's certainly true that many a model has been built with the most basic of tools and very few of them, so don't let collecting tools get in the way of your modeling. Just start picking them up as you go and before you know it you'll have more tools than time to use them.

    As for the proper name of the referenced splice, the lengths I see people go to avoid calling this splice by its proper name in written works never cease to amuse me. It's understandable, I suppose, but "talking like a sailor" goes with the territory. The etymology of the name is glaringly obvious if you think like a sailor. There's only two customary uses for this splice, one being to receive the "button" or "knob" (not the "cascable," which is the entire section of the length of the gun aft of the base ring) and to secure a lifeline made up of multiple splices around each of the outer ends of the bars of a capstan so the capstan can be manned in heavy weather. You're not a real "salt" unless you can call it by its proper name without sniggering.  
     
    Yes, Flemish coils were only seen when laid down for "dress ship" inspections.  So said my retired USN master chief bosun's mate mentor long ago. Flemishing was a temporary thing. Once the ship's dress was struck, they were returned to their proper stowed coil configuration. There are a number of  good reasons for this. First, they are something to trip over and that's never a good thing on deck. Second, the line does not run free from a Flemish coil and the line tends to kink and tangle if one tries to let a line run from a Flemish coil. Laying a Flemish coil up in the traditional fashion, by laying down the first few turns and then turning the "pad" to coil the falling part around the "pad" until it ends with the bitter end, tends to kink the standing part with the resulting twists. Line left Flelmished on deck for long periods of time will cause the sunlight to weather the line on only one side, causing uneven deterioration. Lastly, in any sort of seaway, if running water is taken on deck, the Flemished line floats up and all over the deck, tangling and often ends up flushed and running out of the scuppers and freeing ports. Now, that's not "contemporary" authority, but I'm betting the reasoning was no different in the Eighteenth and Nineteenth Centuries as it was in the Twentieth.

If one desires, holes can be drilled in the edges of the frame of the glass box and through into the edges of the baseboard rabet and a nail, brass escutcheon pin, or other unobtrusive fastener provided to slide into the holes with a "slip fit." these will prevent a disaster from occurring if someone attempts to lift up the case by the "box" instead of the baseboard, thinking it's all attached and whacks the model with the box!

    It is important to provide a means for air circulation in a model case. Otherwise, an acidic atmosphere can be trapped in the case environment and cause deterioration of the model. The acid out-gasses from various sources within the case environment, including PVA adhesives and without air circulation, can reach destructive levels over time. Only a very small hole is required. A space of an eighth of an inch between the side of the baseboard rabet and the box bottom rectangle and a space of and eighth of an inch between the baseboard and the bottom of of the "box," provided by something like those adhesive felt "buttons" they sell for putting on the lower back edges of picture frames so they don't mark up the walls should be sufficient. The "rule of thumb" is that there should be one square inch of "hole" in a case for every one cubic yard of a case's interior volume, so it doesn't take much to provide enough circulation. An alternate method of providing ventilation is to make the base rectangle higher than the size of the rest of the framing rails and drill a few ventilation holes through the back of it. This "heavier" base rectangle side can also be more aesthetically pleasing, particularly if the baseboard plinth upon which the model is mounted is raised up a bit.

    There is at least one article on building cases in one of the Shipmodeler's Shop Notes volumes and perhaps a few posts about case making on the forum, but the search feature didn't help any when I looked for them. It's a simple enough project to make a case, although it helps to have three arms! A decent table saw is a must and you'll need to have a way of making very exactly accurate 45 degree angle cuts. This is where your Jim Saw will really come in handy!  A picture framer's 45 degree corner clamp is also very handy, although one can build their own jig for this purpose easily enough.
     
    I've found the best-priced glass can be sourced from places like Michael's that do custom framing. Ask them to cut to the exact dimensions you specify and buy the picture framing glass with the UV-blocking filtering in it. I've also used simple window glass, which is a bit cheaper, but I've found a glazer's shop may not cut to the exact measurements you request and may not have the thinner glass you'd likely prefer.  
     
    Construction is pretty simple and any article on building cases will give you the details. You can pick whatever method you prefer. I like glass because it doesn't scratch like the plastics can and it's less expensive. It's easier to clean, too.  I've found that you can't build a glued box plexiglas case unless you are a pro. They use special proprietary adhesives that dry to an invisible weld at the corners and if your adhesive (I've tried CA) goes anywhere that you don't want it, you'll have a mess that is relatively impossible to buff out unless you are using the professional proprietary adhesive which is only sold to licensees, I believe. If you prefer plastic, you can always build a wood frame case and glaze it with plastic.  Plastic out-gasses and that troubles me in terms of archival quality. Others' mileage varies in that respect, of course.
     
    One can buy case kits, but they are expensive and the size selection is limited. Purchasing a professionally built case has always been prohibitively expensive in my estimation, although I have the tools to do it in house myself, so I'm biased in that respect. Most of the case kits on the market do not include the glass or plastic. Shipping the fragile built case from the manufacturer is quite expensive, as well. I expect the special handling and insurance is costly.
     
    After trying a number of construction methods, I've settled on what I've found to be the most simple. I make two rectangles with 45 degree mitered corners. these define the shape of the top and bottom of the case frame. The top rectangle has a saw kerf cut into the inside sides of it, as well as on the bottom sides of it. (A table saw blade kerf just matches thickness of the glass I use. It should be a tight fit.) The top rectangle is assembled with the glass held in place in the saw kerfs. The corners are glued with thickened epoxy adhesive and allowed to set. Diagonal holes are then (carefully) drilled at right angles to the joints and a dowel or metal pin (or two, depending on the size of the case) is inserted into the hole(s) at each corner and glued with epoxy or CA. The bottom rectangle is assembled in the same fashion, but without the glass, of course, for which reason it will only need saw kerfs on its top sides. Then four posts are cut and saw kerfs run on the two inside sides of each post. (All this kerf cutting will take careful measurements to ensure the kerfs on the posts will be in line with the kerfs in the top and base.) The entire case is then assembled with the edges of its glass sides being captured by the saw kerfs in the top and bottom rectangles and the side posts and the side posts are glued with epoxy to the top and bottom rectangles. (Here again, fitting is critical. A little bit of extra depth in the saw kerfs is helpful. Do not force the glass panes into the kerfs. Don't ask me how I know this!) When this epoxy is cured, again carefully, drill one or two holes in the top and bottom rectangles at each corner and insert a dowel or metal pin cemented with epoxy or CA.

    Be sure to save the box and packing materials. You will need them for sending it back.  
     
    Tubed quality artist's oils and acrylics properly thinned as they have recommended are fine for airbrushing and also for brush painting. They are intended to be thinned as the user requires. While you may have to acquire the skill to mix colors which perfectly match 1942 Wehrmacht armor paint as opposed to 1943 Wehrmacht armor paint, as some require, tubed paste artist's colors are far less expensive than the small containers of model paints and particularly so the small premixed bottles of "airbrush paint" for modeling. The tubed colors are also far less likely to dry up on your shelf.

    Bob Cleek got a reaction from Landlubber Mike in Priming Below the Waterline   
    The distinction between primer and sanding undercoat is often overlooked. Primer is thin and soaks into the bare wood surface. It can be thinned paint or shellac. I prefer shellac as it is thinned with alcohol and dries quickly to a hard coating that sands easily while penetrating the wood well. For those using water-based acrylics, you should not use a water-based primer on bare wood because the water will raise the grain on the bare wood surface. For this reason, among others, my standard primer is shellac. (Which is also cheap and readily available!)
     
    Applying repeated coats of thin primer will take much longer to fill grain and other imperfections, as will applying repeated costs of finish paint. Sanding undercoat is a huge time-saver. Also note that filling imperfections with sanding undercoat has its limitations. It isn't intended for filling a 1/32" gap in planking. For that use surfacing putty (sometimes called "fairing putty",) which is a peanut-butter consistency acetone-thinned material similar to sanding undercoat that is used for filling larger imperfections. Surfacing putty should be covered with primer or sanding undercoat after sanding fair and before applying any finish paint because it may absorb some of the later-applied coating and create a visible difference in the later coat, often a "flat finish" that sticks out like a sore thumb on a gloss finish coat.
     
    Once primed, a sanding undercoat is used to fill the small imperfections and grain. This undercoat paint is relatively thick and contains a fair portion of talc (chalk) which is what thickens it so it will fill the low spots and makes it very easy to sand. The undercoat, when fully dried, is sanded smooth. If some imperfections remain, another coat is applied and sanded again, and so on until the surface is perfect. Close examination under good light is preferred, and for final examination running the fingertips lightly over the surface is recommended because your fingertips are more sensitive for judging smoothness than your eyes.  Only after the surface is prepared in this fashion, should one apply the finish coats thinly until the desired finish is achieved. 
     
    Oil-based sanding undercoat can be covered by water-based finishes because it is sufficiently flat to provide a mechanical bond, although if one is using  a water-based finish coat, it's safer to use water-based sanding undercoat. Oil-based paint and varnish are preferred for fine finishes due to their more durable harder surfaces which are easier to sand and polish. However, many prefer acrylics for their faster drying time and other more user-friendly qualities.
    '
    And the one rule that must often be followed and is rarely mentioned is to always, always, always, test every paint or varnish you are going to use on a scrap of the same material you are going to finish before you start applying it to the finished workpiece! This may be difficult for the impatient, but the additional time taken will ensure you avoid tremendous grief. Finishing is sometimes a mysterious process. Sometimes the smallest differences in the mixing of materials, their age, or the ambient environment can result in a failure, usually in adhesion or drying. It's often difficult to know why and frequently unpredictable. It's far better to know that before you've an applied incompatible or defective coating to an entire hull or to small, detailed parts that are nearly impossible to strip and start over on.
