Join a round to a flat ...?
It's complicated, but I make an endcap for a carbon tube that connects to a windwing. The white piece is the connection to the wing. I have a small lathe to make the end connectors for the tube. There is a small white item in the photo - it was easy to simply drive a long hole bit down the center of one large piece and cut in half to make two cradles. But, now that the white piece is longer by necessity, I cannot make the cradle.
I thought - Hell, just flatten the wood end piece. Not so easy - once off the lathe. 'Function' could live with flat-to-round, as there is no real load, and a SS screw all the way thru to a hidden nut is quite secure, but it looks like I don't know what I am doing, or lack the proper tools for the job. Both the last bits are mostly true.
I have a series of inexpensive tools and not much experience. I have made protective (sewn) products for aircraft for ~40yrs, but this is outside my skill set. Perhaps there is an easy way? I'd appreciate some suggestions. Thanks.
