I'm planning to make this bracket with CF but don't have a lot of experience working with it and need advice.
1) the radius of .5 in the ones with the ? mark. How small can I go? Thinking about using vacuum forming.
2) For the shape. I'm thinking about making a male in wood, lay the fabric on top and once is cure machining the contour. Is this a good idea?
3) What about the thread. Should I make a metal insert ?
Any advice would be welcome.
thanks

Finished the sides of the mold. Haven't done the middle plate yet since the dimensions are going to depend on the amount of CF layers. Also machined those 2 inserts to be sandwiched in the CF to be able to tap the holes. What is my best option in terms of structural strength. Full CF laminate or sandwich? I'm thinking to lay Coremat but I'm open to sugestions. This part is the hinge of a back rest for a recumbent bicycle. I know is hard to tell but any guess of how many CF layes to make it?
Thanks
