Carbon Cable Guides

I started working on some carbon cable guides for the latest frame.  After a few tests of two quick molds I manged to get an acceptable guide blank for testing.  Here is the progression from mold one, under compacted to mold 2 fully compacted and cured solid carbon composite.  These were made out of woven pre-preg and baked in the oven.
I ground, milled and sanded one into shape and test bonded it to a frame tube with DP-420.  I'll do some load testing to failure before applying them to the frame.
Another view.
The joint epoxy coating and sanding is almost complete as well.
