Day 4: Carbon Wrapping Completed
Head tube lug after initial filing/sanding. Recommend a power detail sander for this work. Knocking down the ridges is important to reduce stress risers that can lead to cracks. Though the surface now looks grey, it will go dark black after a finish coat of polyurethane is applied.
I followed the BBS recommend carbon wrapping procedure as best I could, but it was my first experience using carbon tow and hand layup. The wrapping sequence is fairly complex so take notes while watching the videos and draw diagrams if needed. I would switch to the slower setting West System epoxy hardener to give more working time...I found I was hurrying too much while doing this work.
