  1. The tight grained fruitwoods like cherry, apple, and pear as well as the classic boxwood can be difficult to stain.  Ordinary oil based stains sold in hardware and home improvement stores are pigments suspended in oil, and often do not penetrate the wood well.  I have had much better luck with analine dye stains.  These are sold by specialty woodworking businesses and come in small bottles.  To use, a small amount is mixed with either water or alcohol.  A bottle goes a long way.  Don’t worry too much about the name instead look at a color chart.  I have some “Colonial Maple”. That can yield light to quite dark results depending on concentration.

  2. First decide what you want the finished model to look like.  Your artistic vision should determine your wood selections.  The original ship was probably treated with a preservative like pine tar.  If you are trying to reproduce this look choose a wood that will take a dark stain or choose a wood that gives an impression of the color.  Cherry or Swiss Pear come to mind.

  3. In the metal fabrication business bending a rectangular tube where the side to be bent is the widest of the two is called “bending the hard way” and this is an apt description here.  I don’t understand how the kit manufacturer intended you to bend a 3/16” thick piece of wood with a width wide enough to accommodate cutting out the inside curve.  Frank’s idea of cutting both sides of the curve from a sheet of 3/16” basswood is the practical solution.

  4. We could help you better if you could tell us more about what you are trying to do.  Is your kit a solid hull or a plank on bulkhead,  are you trying to carve the waterway from the solid hull or you cutting a strip of wood to use? 

     

    As as posted above the waterway is a timber at the junction between the deck and the bulwark.  In some solid hull models it is necessary to thin the bulwark.  Did you mean to say that you are trying to thin the bulwark?

     

    like the old saying goes, "A look is worth a thousand tells."  Post a photo of your situation.

  5. Depending on where you live there are backwoods sawmills that will custom saw a log into planks.  In Southern Ohio they are known as “pecker mills” as in woodpecker.  Two problems.  First of all, you have to get the log to the mill and second many of these guys will refuse to saw up a log if they know that it came from a surburban location due to the possibility that there is a nail embedded in it.

     

    A better choice would to advertise in the paper for someone with a portable bandsaw or chainsaw mill to saw up the log on site,  the sawing cost to be paid as a share of the lumber.  Our local paper has a free swap column that would accept such an advertisement.  Keep in mind that basswood lumber is not expensive so the log may not have as much commercial value as you might expect.

     

    Actually, for modelers shorter pieces that can be split are easier to use as a quartered piece can be cut into blocks with a table saw or bandsaw.

  6. Most big box home improvement stores have a rack of handyman steel.  If you can find some small channel (u shaped stock) it would be perfect for your purposes.

     

    Making sharp bends in Aluminum can be iffy.  Aluminum and it’s alloys is subject to age hardening.  As Aluminum sits around at room temperature it hardens over time and loses ductility.  It can, therefore, crack during bending.

  7. I see no reason not to use “mild steel” from a big box store.  I believe that the previous discussions about tool steels had to do with making edge tools where heat treating to maintain an edge was required.  This is not your situation.  You only need sufficient strength to withstand clamping forces.

     

    Another source of small sized square steel bar is “key stock,” used in keyways of rotating shafts.  You should be able to find this at any industrial supply business. One such company that has retail outlets, at least here in the Midwest is Grangier Supply.  You can also find them online.

  8. Michael,

     

    In the 1920’s The Herreshoff Manufacturing Company Built a 30ft Tender for J. P. Morgan’s yacht Corsair III.  You can find information by googling Corsair HMC Co. #381.  This will take you to information held by the Herreshoff Museum.  The Hart Museum at MIT owns Herreshoff’s Drawings and their holdings have supposedly been digitized.

     

    I also have a SNAME paper about the boat’s recent restoration that includes a drawing with a body plan.  If this interests you send me a PM.

     

    I realize that this is not the model that you are trying to build but it is a well documented example of a small, well appointed, motor boat from the early 20th Century.

  9. The problem with carving solid kit hulls is establishing and maintaining a datum that templates can be registered against.  Like Pete, I enjoy carving hulls but I usually carve two half hulls, port and starboard so that there is always a flat datum, in this case the hull’s centerline to lay against a flat surface when checking progress with templates. 

     

    In in your case you will need to accurately establish the centerline on the roughly carved hull and you will have to be very careful that the templates do not get rotated as you progress down the length of the hull.

  10. Strictly my opinion, worth what you paid for it, but I believe that you could build a successful model from the NRG plans by “lofting with a xerox machine.”  You have selected a model where the full sized prototype was not lofted.  The flat bottom was built then the frames were erected.  The frames were shaped using moulds many of which were the same shape.  If it were me, I would get the NRG plans and try to use them first.
