I am so impressed with the compaction performance of the elastic waistband material, that I am proceeding with a carbon layup over my practice head tube ABS core. I still have not answered the concerns of how to manage dissolving out so much ABS, nor am I certain if the acetone is damaging to the composite resin.
Carbon applied to headtube and first starting compression wrap:
Unwrapping from the vacuum bag I find little resin in the bleeder.
Compaction is excellent. No wrinkling or puckering of the fabric. Orientation of the fibers is very close to how I laid them down before the compression wrap. Surface finish is amenable to adhesion for next layup. I am happy with these results.
The one problem I found was the wrapping did slightly slide down the conical bearing race leads. The sliding allows the fibers at the bearing races to fold over the wrapping tape. This is not acceptable. I will need to be more careful with how I wrap these areas. I should also remove the taper and also try a wider elastic band.
