I didn’t want to cut the plates individually because the 1/2 id copper is thicker than the plys and I don't trust my cuts to be consistent.
The plan is to glue together all the inner parts, then drill out an arc with forstner bits.
Then I could insert the copper and glue it down.
First, I drilled pilot holes so I had the same arc on the left and right halves.
It seemed to work fairly well. Unfortunately, I didn’t get any good pictures of the copper glued down before I glued on the cheeks.
|I micro ballooned the visible sides and graphited the inner parts.|
|Microballons to smooth it all out. Tape was over the copper.|
|Also microballooned the top.|
|And graphited the inner.|
The next step is to glue the cheeks on and then coat them.
I mentioned earlier that I wanted to hang the centerboard and rudder for final coating. I got that done and they look good. I'll get around to sanding & priming the rudder. I might leave the centerboard black. Not sure yet.
