And you can't help but wonder
How long it will be
Before the restless ocean
Comes lapping to
the branches of the trees

Re: Friday PicFest No.313
I was asked to make a longer version of a Trek seat cap/post. Using a existing carbon post as the top portion I managed to roll wrap over a mandrel and the existing post stub.

I used a UHMW mandrel calculating the thermal expansion to get the finished ID correct.

There are 9-10 layers of 300gsm woven carbon with about 50% of the layers at 0/90deg and the others at -45/45 deg.

After the layup was complete I used shrink tape wound tightly on the lathe before curing in the oven.

This is the result after post cure sanding. There were some cosmetic wrinkles in the upper layer of carbon as a result of the shrink tape shifting during cure. The part will be painted to match the frame so it was not an issue.

On a side note, anybody have experience with an Atloas 618 lathe? I could get one used for 500$.
Cheers!
