NenadM, The technique of making round masts from square stock seems intimidating at first, but it is actually very easy. And it allows you to create the square or octagonal cross section parts as well as the round parts all in a single piece. Try it and you might like it. Here are a couple of links: https://modelshipworld.com/topic/19611-albatros-by-dr-pr-mantua-scale-148-revenue-cutter-kitbash-about-1815/?do=findComment&comment=904995 https://modelshipworld.com/topic/19611-albatros-by-dr-pr-mantua-scale-148-revenue-cutter-kitbash-about-1815/?do=findComment&comment=908539

More details for the rigging of the fore top. After the shrouds and tackle pendants were in place (and the loose shrouds were tightened) the next thing was the pendant for the fore gaff throat halliard. I put a short leg and long leg in the pendant from the double block. On the ends of each leg are eyes, and these are tied together with lashings on the starboard side of the mast head. The halliard loop rested on the shrouds and the pendant hung between the tresletrees on the aft side of the mast. The rake of the mast allows the block to hang free. The next consideration was rigging the fore course yard sling pendant around the mast top. The sling has two parts. The upper pendant loops around the mast top and hangs down in front of the mast, with an eye in the lower end. The lower part wraps around the yard and has an eye above. The two eyes are tied together with lashings to support the yard. There were two options for this. A common way to rig the sling is shown on the left in the drawing above. The sling just wraps around the back of the mast and hangs on the outside of the trestletrees and cheeks. However, this causes it to pull tightly around the edges of the cheeks, where it will chafe, and come together at a fairly wide angle at the eye above the spar. This means the lower part of the sling that wraps around the yard must be very short if the yard is to hang close to the top. Another way to rig this is to lead the arms of the pendant forward over the fore crosstree and then down to the yard. But this causes the sling to ride over the fid for the fore topmast, causing it to chafe and lying in the way when the topmast was to be lowered. The alternative is to loop the sling over a thumb cleat on the aft side of the mast a distance above the trestletrees as shown on the right side of the drawing. The sling pendant then hangs over the forward edge of the fore crosstree and comes down in a narrow angle to the eye. The eye is higher between the cheeks, allowing the yard to be rigged higher. It is this method that I chose to use. Again I created a long and short arm for the sling pendant, with eyes at the ends of both parts. These were lashed together on the port side of the mast top. The lower part of the sling loops around the yard. The fore stay loops around the mast top and rests on a thumb cleat just below the top cap. In the drawing above I show it hanging outboard the cheeks and behind the forward crosstree. But it actually gives better clearance for the other rigging if it hangs over the forward edge of the crosstree as shown in the photos. Some drawings show the stay to be spliced to form an eye around the mast and others show it "moused." I decided to try to create a mouse for this model. The mouse is just a lump on the stay that is too large to pass through an eye in the end of the rope. I made the eye small enough that the 0.055 inch (1.37 mm) stay rope will just barely slip through it. I tried a couple of methods to create the mouse. First I just tied a simple overhand knot in the rope and then tried to wrap 0.008 inch (0.20 mm) rope around it. This produced an unsightly asymmetrical lump. I started over and used a needle to work the small rope through the larger stay and then began wrapping layers of the small rope around the larger one, like serving but in multiple layers. I made the larger part of the lump on the lower end - where the eye will rest - and tapered it toward the top. I applied white glue between layers to hold the mouse wrappings together. I think I got a bit carried away and made the mouse extra large, but it works! At this point none of the shrouds and stays are fastened to the hull - I haven't installed the lashings on the deadeyes and hearts. But the next things to install are the jib stay and preventer, and these will pass through holes in the bees on the bowsprit and have deadeyes on the lower ends. Then everything will have to be tightened with lashings and the mast will be permanently in place.

I showed my deadeye rigging tool earlier, but here are some photos showing how I make them. I drill a hole pattern in a scrap piece of wood, with pairs of holes the same distance apart as in the deadeyes, and the hole pairs the distance between the deadeyes (3-4 deadeye diameters). Be sure to solder the twisted part before cutting and trimming wire the loop. They say "the proof is in the pudding," and here you can see that these tools do space multiple deadeyes evenly. However, all is not right in the world. Things started ganging a-gley immediately. On the positive side, it is another learning opportunity. I decided to attach the deadeyes to the ends of the shrouds before rigging them - at least one of a pair that share the same rope. It is a lot easier tying the throat seizings on the bench top than on the model! The idea was to run the shroud around the mast top and tie off the eye around the mast, pulling the loose end of the shroud to get the rope taut before closing the seizing. However, the mast top is very crowded, with lots of ropes that can move around, and many in the way of tying the seizing. As you can see in this picture, it didn't always work and some (two) of the shrouds are just too slack (25%). I could pull them taut with the lashings, but this would leave the upper deadeyes out of alignment with the others. The whole idea behind using the deadeye tools is to get them in a nice straight line. Punt! A better way to proceed would be to loop the shrouds around the mast top, pulling the ends behind the mast where there is ample room to tie the seizings. Then pull the ends of the shrouds between the crosstrees and let them hang loose. Each line can be pulled around the appropriate deadeye and when taut the two parts can be taped together until the seizing is finished. This would allow for adjustment to get all lines taut before seizing any. Also, this allows you to adjust the shrouds and backstays so the mast is vertical before fixing everything in place. I also found it to be extremely frustrating trying to tie the throat seizing in place on the model. So I gave up and just used two round seizings. The seizing closest to the deadeye was done last, and I continued to wrap the line around the shrouds closer and closer to the deadeye until the loop was tight around the deadeye. I will depend upon the white glue to hold things together and prevent the shrouds from working loose through the seizings.

John, Thanks again! Per, Some people don't like Petersson's book. The best I can tell is because he was describing a specific schooner the Experiment, built in the U.S. for the Swedish navy, and not a lot of schooners. He describes a model of the ship, not the real thing, and he says the model was not an exact copy of the original. There are some peculiarities in how it was rigged, but I suspect you can say that about how any specific vessel was rigged! But his book is one of very few that address the rigging and belaying of a topsail schooner. I find it very useful for comparing with Marquardt and some other texts that describe schooner rigging. And it is interesting to compare how Petersson, Marquardt and Chapelle describe topsail schooner rigging compared to what Biddlecombe/Steel, Lever, Lees and zu Mondfeld say about large square ship rigging. Schooner rigs follow most of the same "rules" as larger ships, but masts and ropes are generally only 2/3 to 3/4 as large as on the square riggers.

I have started on the foremast shrouds. The first problem I encountered was how to rig the mast tackle. On larger vessels the burtoning rig was often attached to the topmast hounds, but on smaller vessels the tackle was on the lower mast top. Darcy Lever's The Young Sea Officer's Sheet Anchor (left) shows several ways to rig the tackle. The two examples on the left (naval and merchant versions) show a cut splice around the mast. The center drawing shows the tackle pendant as the extension of one of the odd number shrouds. Petersson's Rigging Period Fore and Aft Craft (right) shows another arrangement for the mast tackle. Lees' Masting and Rigging of English Ships of War, Marquardt's The Global Schooner and zu Mondfeld's Historic Ship Models all repeat versions of these designs. All say that warships had the tackle pendants individually spliced around the mast heads, but merchantmen tackle pendants often used the cut splice or were part of an odd shroud. The arrangement Petersson shows is also mentioned. But none agree on the order the shrouds and tackles are placed on the masts. They all say the starboard forward shroud pair is placed first, and then the port forward shroud pair. But some imply that the mast tackle is put on before the shrouds, and others say they are the last to go on! I have decided to use the arrangement shown in Petersson, and to put it on first. In this way the loop of rope around the mast will also serve as a "cushion" for the shroud ropes, and the tackle pendant will descend inboard of the shrouds. This is important because the tackle pendants and the associated runner and luff tackle rigs will be inboard of the shrouds and rat lines, and hook onto eyes in the channels. I placed one twist of the rope around itself in front of the mast and added seizing on both sides of the mast. In all cases I apply a drop of white glue (school glue) to the seizing to secure the fastening. I use the ordinary white glue because it drys clear and virtually invisible. It can also be loosened with a drop of water to untie the seizing. The tackle pendants are about 1/3 of the lower mast length between the deck (partners) and the hounds (trestletrees). This length varied with the period, and was sometimes half the mast length. The deadeyes are rigged as shown in Lever's drawing at the top of the page at upper left. Several references were specific in saying the deadeyes were fastened to the shrouds with a throat seizing, as shown at left in this drawing from Lever, but with two seizings above the loop. They also specify this type of seizing for use on stays and other parts of the standing rigging - but don't say why. I have noticed that simple round seizing (like the upper seizing in this drawing) but without the lower seizing around the loop) can slip, allowing the end of the rope to slide down and out of the seizing. This has happened to me a couple of times after I have finished the round seizing but didn't allow enough time for the glue to dry before putting strain on the lines. But with the knot around the loop in the throat seizing this does not happen. This may be the "accurate" way to fasten deadeyes to the shrouds, but it is a pain in the posterior to tie that first seizing around the loop with the deadeye in the way! It would be a lot easier to just use the round seizing! There is another detail to be noted on setting up the shrouds. They were made differently for cable laid rope (left hand spiral) and hawser laid rope (right hand spiral). Lees says English men of war always used cable laid rope for shrouds, so American vessels probably followed suit. Coincidentally, the 0.035 inch brown rope from Syren that I am using is cable laid (not all Syren rope is cable laid). With cable laid shrouds the end of the shroud rope is on the aft side of the deadeye on the port side of the ship, and on the forward side of the deadeye on the starboard side of the ship. In this image you see the deadeyes from the starboard outboard view, so the inboard side of the port deadeye and the outboard side of the starboard deadeye are seen. When the lanyards are rigged the standing end has a knot to prevent it from pulling through the hole in the deadeye. The lanyard is first pulled through from the inboard side of the deadeye through the hole shown in the drawing (forward on the port side and aft on the starboard side). After the lanyard is run through all the holes in the deadeyes the loose end is fed through the gap between the upper deadeye and the rope loop (not shown in the drawing) then round the shrouds and back under itself. It is wound around the ropes a few times and then seized to the shroud ropes. It will take me a while to finish rigging the shrouds to the two masts.

Kieth, I like the way you think things through and plan carefully. OK, so the first effort at the stern tube was a bit off, but if you weren't being so thorough checking and rechecking you wouldn't have noticed - and neither would anyone else! I enjoy following your work, and always look forward to learning from you new and better ways to do things.

I hope you start a thread for the Achilles.

You can try to make your own stepped mandrels using square metal tubing. McMaster-Carr has a wide assortment of metals and tubing sizes where each size slip fits into the next larger size. For example they have brass tubing stepped in 1/32 inch increments: https://www.mcmaster.com/products/rectangular-tubing/material~260-brass/ By getting and assortment of sizes, slipping them inside each other and soldering them together you can make a square mandrel like you are looking for.

In my early planked hulls I also had problems with the wood shrinking and swelling, opening cracks in the hulls even after they had been sealed and painted. About 35 years ago I started using a thin clear two part epoxy paint to seal the interior of the hulls. This paint is used by airplane modelers to seal wooden engine mounts so they don't soak up fuel. The paint filled in any cracks between planks and soaked into the planking and bulkheads/frames. After it hardened the planking was very solid. After 35 years of long wet winters and hot dry summers there have been no cracks opening in the hulls.

I have used thin aircraft plywood for small wooden parts like the boom jaws. Plywood is much less likely to break while working on the parts. They were cut out to rough shape and then filed to the final shape: https://modelshipworld.com/topic/19611-albatros-by-dr-pr-mantua-scale-148-revenue-cutter-kitbash-about-1815/?do=findComment&comment=1012539 I am modeling an early 1800s vessel so I used metal bands around the boom jaws: https://modelshipworld.com/topic/19611-albatros-by-dr-pr-mantua-scale-148-revenue-cutter-kitbash-about-1815/?do=findComment&comment=1012900 Later vessels used bolts instead of the metal bands. I don;t know what the Bowdoin used.

I have been reviewing all of the rigging and the belaying plan and making last minute additions and adjustments. I discovered I have overlooked the main sail tack, and a place to belay it. I did have the fore sail tack attached to a luff tackle to a ringbolt at the base of the fore mast. But I had overlooked the tack for the main sail, and this caused a problem. The bell was in the way! The tack of the gaff sail was sometimes attached to a luff tackle that hooked to a ring bolt at the base of the main mast. This allowed the tack to be pulled down to stretch the luff edge of the sail taut. But sometimes it was simply strapped to a ringbolt on the boom jaws. In this case just the weight of the boom might hold the sail down, but I have seen a (rare) reference to a tackle to haul the boom jaws down against the boom rest. In either case, the tackle must run down the aft side of the mast to a ring bolt on deck, and I had placed the ship's bell directly in the path of the tackle. I had wanted to place the bell on the fo'c'sle because I have read that by the late 1700s this was where bells were being located. My earlier experiments with a belfry were an unsuccessful attempt to do this. I found some photos and drawings of bell attachments on schooners of the late 1700s through the 1900s and smaller vessels often had a simple bracket for the bell, and it was often attached to knight heads or windlass supports. I don't want the bell rising high where it might interfere with the forestay sail so I devised a simple bracket to mount the bell on the bitts securing the base of the bowsprit. I did not intentionally "weather" the finish on the bell bracket. I have had frequent problems getting the blackening (Birchwood Casey Brass Black) to produce an even finish. The metal was washed with water and dish soap, then thoroughly rinsed. Then it was washed in acetone and then isopropanol, and the parts left for the alcohol to evaporate. After this it was left in warm vinegar for about ten minutes and washed in water. Then I actually left the bracket in the blackening solution for twice the time (10 minutes) I normally use. As before the results are blotchy. But it will do. Now the aft side of the main mast is clear to allow the run of the main sail tack tackle (if I install one) or any other line that may pass there in the future! I think I now have a complete rigging and belaying plan (but I have thought this before) so now maybe I can step the masts and start rigging!

White lettering decals..How?
Dr PR replied to wmherbert's topic in Painting, finishing and weathering products and techniques
Here are some words of caution about do it yourself decals. I have prepared quite a few over the years - and white has always been a problem! There are decal papers for ink jet printers and laser printers. Ink Jet printers: The inks are water soluble, and that can be a problem with water slide decals! You may need to coat the printed decal with a clear finish before using. Laser printers: These can produce decals that do not have water soluble inks and do not have to be coated before using. CAUTION CAUTION CAUTION! Laser printers have a heated "fuser" that literally melts the toners (ink powders) onto the paper. Some printers caution about using any paper with a clear shiny coating (glossy photo papers, decal papers, etc.). The fuser may melt the coating, DESTROYING THE FUSER! I speak from experience! I used a glossy "laser printer" photo paper on a very nice Samsung laser printer and afterward it wouldn't print correctly. The fuser had glossy goop on it that prevented it from picking up the toner. Then I learned that printer didn't have a replaceable fuser (every other laser printer I have owned did have a user replaceable fuser). The entire $600 printer was junk. I replaced it with a Brother "laser" printer that has a replaceable fuser. But it really isn't a laser printer - it has a 600 dpi LED bar to expose the image onto the fuser. It has a VERY hot fuser that melts the glue on envelopes! I contacted Brother about whether it could be used with laser decal papers and the advice was NO! No glossy or non-paper materials at all. I have printed decals on other laser printers in the past with no problem. Recently I printed some color decals at the nearby FedEx Office Store. They used a laser printer that was OK for decals. However, I was trying to match the colors on an object, and the FedEx printer produced different colors from what I get printing draft test sheets at home on paper. I eventually found RGB colors that would print the desired colors on the FedEx printer. Check your printer's manual to see what materials they recommend (or don't) for printing on. -

What glue to use
Dr PR replied to David Enghauser's topic in Building, Framing, Planking and plating a ships hull and deck
I don't especially care for "super glue" (cyanoacrylate). It sets too quickly to allow for adjustments. CA doesn't adhere well to metals. It leaves a permanent blemish (shiny spot that won't take stains) on wood surfaces so be careful using it on surfaces that will not be painted. I have used Sig-Bond aliphatic resin for gluing wood. It does take a while to set up, but makes a strong bond to porous materials. My favorite glue is Duco Cement (nitrocellulose in acetone). I have been using this glue for perhaps 70 years. It sets quickly (about 20 seconds) but gives you time to adjust things. It hardens fully over night. It adheres to wood, glass, plastic and metals. But the best "glue" for non-porous materials like metals and glass is epoxy. It also works well for porous materials like wood. In fact, it is probably the best glue for anything, but is not as convenient (has to be mixed immediately before use) as other glues. -
White lettering decals..How?
Dr PR replied to wmherbert's topic in Painting, finishing and weathering products and techniques
Here is another option using rub-on letters as stencils. 1. Get some rub-on letters in the desired font and size. Color doesn't matter. 2. Paint an area with the desired letter color (white for example). Let the paint dry thoroughly. 3. Rub on the letters, placing them carefully, of course. 4. Paint over it all with the background color (black, for example). 5. Let the paint dry. 6. Use tape to remove the rub-on letters. Now you have white letters on the black background (or whatever colors you use). There is no decal film around the letters, and they are only as thick as a layer of paint. The lettering will not yellow as decals do over time. I have been using this process for many years, and other that getting the rub-on letters aligned properly it is pretty simple. -
Tiny Spar on 17th Century English Yacht
Dr PR replied to catopower's topic in Masting, rigging and sails
Clare, I have seen this method of strengthening the peak of sails a number of times. I think a short spar like this that is attached to the peak of a sail is called a "club" but I am not certain. The Dutch used a very short spar like this at the peak/head of sails in the 1600s on small vessels (Sailing Ships, Bjorn Landstrom, Doubleday & Co., Garden City, New York, 1969, page 156). This later grew into the common gaff. So if it is on a sail rigged aft of a mast perhaps it should be called a gaff. If rigged before the mast as in your picture I guess it is just a "spar" or perhaps a "club." Somewhere I have a reference that shows how to make these. The sail is laced to the club/spar. The halliard attaches to the spar. I don't know if it matters how, but in your picture it looks like the halliard block is riding on a line attached to the ends of the spar. It may be securely attached to the line at its center, or just sliding along the line. I can't tell from the picture. But I see no reason when the halliard couldn't be attached directly to the center of the spar. Since this idea seems to date back many centuries it is possible it has been used in many rigs in many places. I am sure I have seen it in photos of modern vessels. What is the name and period/date of the English yacht in the photo? The Dutch were using something like this on their yachts in the 1600s and 1700s. The English copied a lot of the Dutch ideas. -
Travis, You have a decision to make. You are working on the beginner's three boat series where you will learn about wood, paints, tools and the basic practice of ship model building. Good for you. You are off to a good start. But what then? You have three choices: 1. Ship modeling just isn't your "thing." Give it up and do something else. 2. If you enjoy ship modeling pick another kit a bit more challenging than the last, a brig, schooner or fishing boat, and build it just for fun according to the supplied plans. 3. Get really deep into the hobby and research every part of your next build to make it as historically accurate as possible. It may be a kit or a scratch build, but the real fun is in the research. Most of us repeat step 2 several times before we plunge into step 3.

USS Constitution by mtbediz - 1:76
Dr PR replied to mtbediz's topic in - Build logs for subjects built 1751 - 1800
Mustafa, Nice work! The Constitution has a special place in the hearts of us US Navy folk. I too have been lusting after the Proxon MF70! There is a trick I use to simplify the making of many identical gun carriage sides (cheeks) or any other similar parts without using a table saw (I don't have a table saw!). I cut a long piece of wood to the right height and thickness of the carriage sides. Then I cut off pieces that are a bit longer than the carriage sides. I line up all of these rectangular pieces side by side and clamp them together. Then I file the ends flat and glue a strip of wood across each end. This produces a single "block" of many identical side pieces that can be milled as a single piece. Then I milled the block, cutting each feature of the carriage sides in all the pieces in a single pass, just as you did with your milling machine. After all the cuts were made I milled off the glued-on end pieces to free up all the individual carriage sides. This also cut the side pieces to the correct length. This produces carriage sides with the wood grain running the length of the pieces instead of across the parts. You can see a stack of side pieces as they came out of the mill (after the glued-on end pieces were cut away) at the upper left of the left photo, and some assembled carriages in the right photo. -
Allan, Good point! Lines couldn't belay to pins unless there were pins to belay to! Before pinrails, fife rails and such, lines were belayed to kevels (cavels), cleats, bitts, knight heads, timberheads and such. Whatever was available it seems. Over the last few hundred years of sail the ships became larger, with more masts and more sails, all with more and more complex rigging. I suspect fife rails and pin rails came into use as a necessity to deal with the ever growing number of lines that had to be belayed, and organizing them in a rational way. There is another exception to the general "rules" I mentioned above. On some vessels some lines, like halliards and bowlines, were run forward of the mast, and the higher they originated the farther forward they were belayed. Again, it was whatever worked to avoid fouling lines.
