It cost as much, prolly a little less, I don't anticipate going thru bits as fast. But there's other additional cost in finishing I'm not quite sure how much, I like to find out the hard way ya know!
Fiber is a time consuming process, but it's also a significant bit harder to work with. You need all new tools: bits n mill bits etc and they wear out fast. They need to be replaced really often or they catch n snag and for simplicity sake rip/unravel the fiber.
I would want to machine it out of a solid block I think.
Then you loose a lot if the strength of the fiber and rely more on the resin.
The strength comes from the fabric and machining it cuts the fibers. You lay the fibers in particular orientations for strength and you loose that ability if machining a pre-cured block.
True; but how strong does it really need to be? I just can't see Tom going from milling and fly cutting to vaccum bags and resin all over. I think I could deal with the strength reduction.
How strong do you want it? It's about as important as using Ti or and esoteric Al alloy.
I do like the look of CF and milling form a block would change the look only 2 surfaces would have the mesh visible. The other 4 would be the looking at the sandwich stack, not really the look CF evokes.
I think 2 round cores wrapped with 2-3 layers, then those 2 wrapped together with 2-3 more layers (like a 2 cell battery pack) would be a good start. Use rolled up cloth to plug the ends. Would take some experimentation to work it all out.
Probably need 3-4 vacuum/cure cycles.
Copper mesh as the first layer on the battery tube (used for lightning strike protection on aircraft) to get conductivity in the battery well.
I think it would be fun to watch Tom with vacuum bags, resin pots, mold release and sticky fibers all around.
Pre-preg could help a lot.
(No, I don't really ever want to do layup again)
That sounds like a hat thrown in the ring....
Yessir I'll be starting on them next week
what about m3? saw a button cover made out of it M3 Blanks & Billets
