Lots of progress this weekend on the 1956/57 Miss Wahoo U-77 1/8th scale RC hydroplane. Got all the frames installed, and a few of the stringers. Will finish with the stringers later this week. Also got the two bottom panels installed. Some of the frames needed a little persuasion to stay put, so push-pins came in handy. Here you can see some of the forward stringers on the bottom. These are the ones that will be epoxied to the bottom panel. Here is the aft bottom panel roughed out. Use packaging tape where you might have some epoxy squeeze-out. Epoxy doesn't stick to the tape. Made lots of progress this weekend! I'm using my rubber-band clamping system on this boat. It was used extensively on my RC sailboats for the frames and especially for the planking. Here is is used to keep downward pressure on the frames, and inward pressure on the outer side panels. It's very adaptable so be creative! The main add-on to ma...
The strongback was built. I made mine out a 3/4" x 2' x 4' sheet of MDF. It was ripped on the table saw to 9 7/8" wide for the top and 4" wide for the sides I had already laminated together the few doubled-up frames and transom. Today I started to epoxy the end sponson frames to the side frames. In the picture below, you can see how a pin was used to keep part of the side frame aligned with the sponson frame. The pin won't stick to epoxy and will come right out when cured. Do whatever you need to do to keep the frames perpendicular to each other. Here are two 90 degree angles being used to keep the frame straight. More to come! Aloha!
