Had a small setback with this frame due to a mislabeled tube and neglecting to measure said tube. The head tube was not 44mm ID. I noticed just prior to bagging for the oven, removed the pre-preg and baked the rest of the frame.
After grinding and prying off the wrong head tube I carefully replaced it after cleaning up the joint. Everything was aligned in the jig to the same location.
Here is the new head tube installed and re filleted.

I start wrapping the head tube joint with uni-directional carbon. I like to use long fibers that wrap around the front of the head tube to anchor the down tube.

After the epoxy set on the joints overnight in the jig I removed the frame, checked the alignment and weighed it. 766g is a pretty good start to having a nice light frame.

I continued to miter and fit frame components into the jig. Below in the ENVE chain stay cut to fit the BB and seat tube. I'm not that impressed with the molding on the ENVE non-tube parts. The parting line is rough looking, stepped and grooved.
