25. Scratch stock for making half-round moldings.
24. Painted hull. Moldings and the rudder and propeller are yet to be added.
Moldings
T ere are a number of moldings around the model: half-round on the hull and quarter-round in other places, all fi nished natural. To make half-round moldings I machine notches in a section of broken hacksaw blade. (Figure 25) T e backs of these blades are soſt enough to cut with carbide cutting bits; I clamped the blade in a milling vise mounted to my metal lathe to do the work. T e result was a scratch stock that I used on the edges of lengths of wider pear wood to make the half-round shape. Sawing the shapes loose completed the moldings. My stock of pear was not long enough to make one-piece moldings and I had to scarf lengths together. Making perfect scarf joints is easy if you have a disk sander. Simply double-stick tape a fence to its table and push a length of molding between your fence and the disk to sand a long angle on the end. Do the same to a second piece and the parts will make a perfect scarf joint when glued together. (Figure 26) When I glue long pieces like these half rounds I use thin CA (and I used that for most of the remaining bonding on the model, too.)
Quarter-round molding starts out the same as half- round: I then thickness sand it to the proper thickness and rip it off the wider strip.
T e only molding that I could put on at this point was

the heavy rub rail at the bottom of the black sheer strake. T e others would have to wait until decks and other parts were installed. T e rub rails were heavy, triangular pieces that I made from basswood thinking it would be easier to bend. T at was something of a mistake and, thinking back on it, I probably should have used alder. Nevertheless, I was able to wet them
