• Put the electrical tape to mask off the area further away from the repair area. Now the tape acted like a sort of barrier/dam for the epoxy and this created an abrupt height difference between the epoxy and the existing surface. Easy enough to solve if I would sand and paint this area though...
• Use less epoxy for the final coating. Now the epoxy has seeped under the electrical tape and there is some epoxy on the "good" side of the tape. Again this would be absolutely no problem when sanding...
• Put some small strips of carbon on the lowest area's of the repair before the final carbon patch. Now there is a slight indentation where I sanded away the most carbon.

Was on the fence about this frame or a few others I had shortlisted, I think you may have just made my mind up. That looks great 

Where did you order it from and what other parts did you use?

These boutique shops are funny. They're essentially selling painted OEM chinese frames at the price of an SL7.
"material: carbon". Lol.
Not sure whether it's infuriating or pathetic.

Very nicely done, and thank you for sharing your process.
A big advantage of these chinese frames is that if you crash it, you have 500 eur at risk, not 5000. It's the sort of thing that helps sleep better at night.
Good luck with your recovery. Collarbones seem to break like matches.
