All these methods rely on accurate measuring, alignment & centering of frames with the possibility of human error. My method eliminates any need for measurement for frame spacing, squareness or centering as it is all part of the jig. All you need is a table saw to cut a slot down the build board and an MDF board for centering . Then cut up the MDF board (I used a piece of primed MDF baseboard) into 94mm lengths, assuming you are using 6mm frames, for 100mm spacing. Everything is press fit so no screws are even needed except for the end frames and spacers. See these posts for pics and descriptions.

BTW, the 2x3 frame below the laminate covered Jig allows the tilting of the whole model at a 45 angle which assists with the building process.
Also I have covered the laminate with packing tape to make epoxy spills and drips easy once the model is finished and removed from the build jig.

Agreed, and if I had woodworking tools that could handle that size stock I would probably try it.

Cheers,

Just in time for the new year


Just got my ribs from National Balsa. Good cuts and at a very good price. I have my West Systems resin and hardeners and my glass cloth. I have my balsa wood and my building boards. I have 2 weeks to figure out what else I need to get started. The count down has begun.

I finally got to play around with creating surfaces in cad. This one has a distinct rear end which could help a lot in choppy conditions (or not)

Hi David,

Is this from AutoCad? Are they NURBS surfaces?

hey guys, I'm finishing off my keel/bulb and it's coming in a bit light. I need to add about 40g which is a bit much for paint. I was thinking of painting the bulb with a thick mix of epoxy and lead powder. Or something like that. I already tried thickened epoxy with high density filler but that only added about 10g.

Any other proven solutions?

Any major sporting goods stores nearby? See if they cater to the shooting clubs nearby that shoot skeet as many load their own shells. Locally here we can purchase fine #9 lead shot in25 lb.bags. keep in mind weight for shipping costs. Maybe you can share costs h other builders.
