  1. For the basement - first -make sure that it does not leak.

    I had a house in Kentucky where the basement was sited in mid summer during a drought.  Turns out that for six months of the year it was 2-3 feet below the water table.  Nothing but heart ache.

     

    Ideal - have a powerful shopvac - in a distant location - sound insulated from the rest of the house and where you work, vented to the outside,  wired so that you can easily turn On/Off  -  a Great Dane sized dog house close to the house - you just need the 4 inch ducting and  12 ga Romex thru the wall.   Be nice if the 4 inch ducting could run between the floor joists and not thru them.  Works for solvent vapors as well as saw dust.

  2.  

    "Pentacryl, a compound of Siliconized polymers, was originally developed for the treatment of waterlogged wood. It has since been marketed for woodcarving and woodturning to keep green wood from cracking and splitting."

     

    Cuprinol -originally was a copper salt based product intended to protect wood from fungus, insect borers, and ship worms.  I am thinking that copper based compounds have been avoided for reasons of toxicity.  The company seems to have kept the name and moved into other products in the area of wood protection to stay in business.

     

    We probably should not be keeping a model in a outdoor exposed situation, so Cuprinol does not provide a use that we need.

     

    I would advise using well seasoned wood stock to build a model, so a green wood stabilizer also seems to be a function that we do not need.

  3. The false keel was there as a "throw away" bumper?  If the ship ran aground on a moderate slope, it was to come off so the ship could back free?

    Seems to me, it would need to be fastened just enough to stay when subject to the forces of water, but not offer too much resistance to a real shear force.

    I would think that every ship's captain and especially the NCO responsible for the ship's structure would have their own opinion on how to fasten it.

  4. the little scuttle

    Function 1 - to allow the cannon to be swabbed with the lid closed - to avoid flying material coming in during loading - the shaft of the swab would keep it open enough.

    Function 2 - for ventilation when too cold or wet to have main port open - a wooden wedge to shim it open?

    To close it - pull it closed by hand using the ring? If removing the shim and gravity closing it is not enough.

  5. From your photo, this appears to be a POB kit? 

    Is it double planked and this the first layer?

    The purpose of the first layer is to offer support for the actual planking.  On most all kits, the frame moulds are spaced too far apart to give adequate hull shape and plank support.  The first plank layer is intended to provide this.

    Smooth off the planking. (Plane, file, sand, scrape) The gapes will be covered by the display planking. 

    When you have a smooth base, look at it carefully.  If there are hollows/ dips between mould stations use something like Bondo to fill out the hollows so that base hull has the proper shape for the planking.

     

    The real planking will need spilling,

    Ribband location so that no belt of planking has an extreme difference between the plank width at midship  and at the stem or sternpost

    and edge adjusting to give tight seams.

  6. I made a work table using a Flush Hollow Core door.   They come in several widths.  The length can be changed using a saw and the resulting interior gap filled with a piece of scrap lumber cut to fit.  I surfaced the top with a plastic laminate using contact cement.  I set it on two 2 drawer file cabinets and glued wood on the underside that made a "socket" to fit around the top of each cabinet to keep the top from moving.

    I would not do heavy hammering on it, but for modeling it does file.

    Any sort of cabinet would do to hold it up.  Get a set that is shorter than you want and set them on plywood or wood to boost the height.

    It is easy to disassemble.

     

    Thinking about this has given me an ideal:  The file cabinets are low cost and I not sure the metal gauge is not much thicker than something to wrap a sandwich, but they hold things up just fine.  The sliding file drawers are not a very efficient form of storage, though.  I think I can discard the drawers and fit shelves into the openings.

  7. The paper method is an old one. 

     

    There is an article in a past issue of the NRJ that discusses the effects of scale on color perception and that distance changes color intensity and sheen and glossiness.

     

    In the light of accepting this phenom. and adapting to it:

     

    In the sailing ship era, the "tar" used was not the petro based material in common use today and was not really pitch black. Instead, it was brown, red brown, grey brown.

    I suggest the following:

    Use paper that is thinner than what the actual scale caulked seam would be.

    Dye it dark brown ( shoe leather dye, wood dye - other similar material).  The smaller the scale - the lighter the brown.

    Glue it to the plank stack with TiteBond or which ever wood glue you use. (So that the paper/wood join is not weak.)

    Separate with a very sharp blade.

    After laying the deck, the last finishing step = scraping it with a single edge razor blade held vertical to the surface.

  8. Mark,

     

    Thanks, 

    I will look to see what is available.

    There were several less than successful experiments trying to find something that worked and could be removed without too much (unacceptable) effort. 

    The shear forces on the paper can be high.  Regular paper backed medium does not last all that long.

    WoodCraft has a cloth backed medium from Germany that lasts.  It comes as a roll and is 4 inches wide. Now I have 3 different grits on the 11 inch long platen. It even stands up to being cleaned using a gummy rubber cleaning stick.

  9. Weldbond - The manufacturer - Frank T. Ross & Sons - is bit coy in how they write the product literature but they do state that it is P.V.Ac - which is polyvinyl acetate - PVA

    It should be essentially the same as other PVA wood glues.

     

    The way my brain stores and recalls info -  Weldbond also brings up Weldwood - the contact cement - which is not so good for our uses.

    I built and use the thickness sander in NRG Ship Modeler's Shop Notes Vol. 1.  The platen is made from turned Rock Maple sized to fit a sheet of sand paper.  It has been difficult to find way to attach - reversibly - the sanding medium.  The way I do it now - use cloth backed medium - attach with Weldwood.  I have found that paint thinner solution Naphtha  works to unstick the medium. It does not dissolve it.  It makes it unsticky and produces removable curd-like lumps. 

  10. Do you plan to fully plank both sides of the hull?

    Yes. - Then it should do.

    In making the sandwich, with PVC glue - within reason - higher clamping pressure = stronger bond. Uniform pressure for all sandwiches will yield reproducible results.

     

    No -  Will it bother you that each displayed frame will have an offset seam near the center with a different grain pattern on each side?

  11. A generic 9" tabletop band saw with a 1/8" blade will do an excellent job of scroll cutting.  With a Carter Products Blade Stabilizer, scroll cutting is even better.  Change to a 1/2" blade and you can do some resawing (in the 1-2 " stock range) and cross cutting (you might could rig a carrier/slide table like with a table saw - the back would need to be uncut to keep the two sides attached).  Inside scroll cuts and extreme curves can be done with a hand fret/scroll saw.

    It gives you a more versatile machine.

    See the size of readily available replacement blades (59 1/2 here) and make sure they fit the saw you choose.

    If the Carter upgrade is do-able as far as cost, make sure your model choice will fit one.

  12. Black Walnut is an attractive wood - for furniture - the grain is tight, so it does not fuzz or roll out as you work it, but it is open, so it is not really the best for 1:48 scale or smaller, especially small parts like deadeyes , blocks, rails, combing, bits, etc.  European kit assemblers probably use a different species, but what I see is still open grain and not as rich a color as Juglans nigra even.

     

    I am not familiar with SoCal botany,  but see if you can source a dead branch of a Dogwood tree - a live one will work, but you would need  it to season before you can use it. 

    If you have old formal gardens there, see if you can get pieces of Boxwood.  Real Boxwood (Buxus simpervirans) from temperate gardens is tight grained and hard as a rock - tough to work.  It may have a faster growth pattern in your warmer climate.  When you prune it (saw out a sizable branch) you will quickly appreciate just how hard a wood it is.

    Rock Maple would be better than Walnut.  Black Cherry would be better than Walnut.  Either would do a good job, they are just softer and faster working than Dogwood or Boxwood. Holly will work and it can be dyed to match any shade of wood.

  13. I had been thinking that "kit bashing" implied the production of a chimera -  a fantasy object.

    In ship modeling the usual goal is produce as accurate a representation of an actual vessel as is possible - given the skill and data available.  If that is the result, then how you get there is not much of an issue.  There is no real "bashing" here.

    When I read a post about a POB kit where the author states that the centerline keel piece, molds, and planking has been replaced with higher quality material - I wonder - why not just buy only the plans and hardware to begin with?  It has essentially become a scratch build at this point anyway.

  14. There has been no reply to this inquiry. Rating ship model kits is not really what this site is about.  The site is little if any about competition at all.  It is about improving the skills, knowledge and resources of each of us through communal effort.

     

    The way you ask this leads me to believe that you are a beginner in ship modeling.  A clipper is a major undertaking.  A wooden ship model, even as a kit is on a different level of effort and skill from most any other type.

     

    Start small with a beginner lever kit.  A site search here should find several posts with advice on which are good choices.

     

    If you have your heart set on a clipper:

    Another way to get your feet wet:  start with a large scale plastic kit of a clipper.  BUT, after you complete the hull, discard the plastic masts and yards and make your own from wood.  Get one or more books covering the masting and rigging of clippers.  Be aware that golden age clippers like Flying Cloud, Red Jacket, Sea Witch -  are a bit different from later ones like Cutty Sark.  The rigging cord should be replaced with better quality and size appropriate material.

  15. Harvesting your own wood, or starting with lumberyard stock is not a requirement for scratch building.  It is more something like a fetish for those of us who want to "live off the grid"  for our wood sources.

     

    As far as scratch building is concerned, I consider that it means starting with just plans and assembling a vessel.  It is freedom from the limitations from the offerings of kit manufacturers.

     

    Using pre-made hardware such as cannon or eye bolts, does not alter that, although it may run afoul of some contest rules if competition is something that you enjoy. I think that the metal parts are more of a Model Engineering skill.

    Prototype ship builders did not hesitate using outside manufacturers to provide wheels, winches, or anything else they could get as soon as the Industrial Age began.  There is no reason a modeler should not do the same if the part matches and is the correct scale - if that is how they wish it.

     

    Not relevant to anything:

    I would not build a scratch model at the same scale of any vessel available as a kit.

    I would never use POB as a method to scratch build.

  16. Primer is to seal the wood and provide a smoother surface for follow on paint or "varnish". 

    Shellac (thinned to 50% if using a product already in solution) is the classic primer.

    Tung oil diluted to 50% (1:1) by mineral spirits is another type of primer. Tung followed by primer strength shellac is another choice.

    Classic vanish is boiled Linseed oil heated to dissolve in shellac - not really a DIY product.

    Sand and Sealer is a product that is primarily intended for use on open grain/open pore wood like Oak, Hickory, Walnut.  It tends to be thick in consistency and will leave a layer that might be out of scale (too thick).

    The reason that a mat finish (egg shell) is preferred is one of scale effect.  Most of us produce models that are between 1:50 and 1:100 of the actual vessels.  An actual vessel with a high gloss finish would appear as having a mat finish if viewed clearly from a distance where it was  seen as 1-2% of its actual size.

    To use polyurethane on your model is a matter of whether you are prejudiced against using plastic on your model.

  17. It is a small piece of wood (end cuts/ scrap usually) at the end of the pin.  Just pinning a plank to a frame is good for locating it, but it does not apply much downward clamping pressure. If you use the pinhead to apply the pressure, a dent larger the the trunnel is often made.  If the pin is thru doweled, the piece of wood is between the pinhead and the plank.  If the pin hole is shallow, the pin is bent above the wood piece to apply the pressure. 

    If you want to go old school, the wood piece is split off and the pin nipped at the plank surface.  You then have brass trunnels.  If you want  wood or bamboo trunnels, the whole hutchcock is removed and the pin hole bored to match the trunnel diameter.
