3. Carving the BulwarksMake yourself a temporary cradle to securethe hull while carving. This cradle also willserve to hold the model for most of theremaining work. Make the cradle so themodel sits in it with its waterline parallelto the baseboard and table. The tops of thecradle should be below the waterline.Later, when you are ready to paint, attacha pencil on top of a wooden block andslide it along the table to mark the locationof the waterline.The machine-carved hull has bulwarksthicker than scale so they won’t break whileinside the kit box. The upper surface is cutto the underside of the cap rail. After youcarve the outside of the hull, the bulwarkswill be thinner. If more than 1/16" thick itwill be necessary to carve the inside of thebulwarks. This is the most difficult part sowork slowly as you carve (Figure A-2). Aftercarving, sand the surfaces smooth. If youhappen to have or want to buy a poweredrotary tool like a Dremel, there are manycutters available to quickly reduce the bulwarkthickness.Note that bulwark brackets go onto theinboard side of the bulwarks. The bracketsshould be 1/32" wide at the top and 5/32"at the bottom. Together with the bulwark,the brackets must fit under the cap railwhich is only 3/32" wide. If the bracketswill not fit, sand the inside of the bulwark alittle more at the top. You can then taperthe inside down to the deck without reducingthe thickness at the deck. You won’treally see that the bottom is thicker thanthe top. Of course, you could use a widercap rail but don’t get it too wide or the scalewill not look proper. Figure A-3 is a crosssection thru the bulwark.Note: As noted earlier, the bulwarks for themodel have been modified from the realboat design somewhat. On the real boat thecap rail and bulwark are constructed from1/4" to 3/8" thick steel plate. At our modelscale these would be paper thin and toofragile for a wooden model. The real boatdetails and the model modifications areshown on the plans.Carving the Bulwark Around the Stern -The bulwark around the stern slopes forwardat a rather large angle. However, onthe real boat, the inboard side is plated inway of the grating platform which covers arudder control quadrant. Carve the insideof the bulwark in this area so the bulwark isvertical (Figure A-4).4. Deckhouse CarvingThe deckhouse construction will be discussedin Stage B.FIG.
