I fucked up on this one. Previous layups had been 1 or 2 squirts of resin and 5-10 pieces of carbon fabric. This time, I tried to push a little harder and put more carbon on the frame... more carbon! 3 squirts of resin and well over 10 pieces of fabric. I could tell there was far too much resin in the layup to seep out... I deviated in my process. Plus I got careless with how I wrapped the compression banding and didn't anchor the start on dry tubing first, so it slid and I see a lot of wrinkling on the bottom of the down tube and top of the top tube.
Damn it. Embarrassed to show this:
I used more unidirectional fabric on this layup. It doesn't permeate the resin from layers below it like a plain or twill weave does, so it was much harder to get the carbon to compact and de-bulk. I was literally massaging the head tube with my hands to work the resin out through the layers of uni.
Terrible:
Hurts to look at this:
I have to sand out all the wrinkles, feather the remaining layers, and re-apply. Painful. Was I drinking too much that night? Can't remember... so, probably yes. Disappointing.
This is the shock-mount uni lay which connects to the mount and distributes the stress into the top tube. Actually quite happy with this result.
I chose to build this frame with wet-layup techniques and developed a process to accomplish that well. I can't deviate from that process. 5-10 layers per layup maximum. 1-2 squirts from the resin bottles. The more uni, the fewer layers as they do not pass resin as easily as the weave.
I've already learned that lesson time and time over on projects past; slow down and do not cut corners to finish sooner. Am I overly excited to ride the frame? Or have I passed the design and invention phase ...where my real interests are... and now I'm loosing enthusiasm for the the repetitive production phase?
