need to cut that small tab off, get to hear this in the recording

Jigging up
jigging up the frame, similar to john kulps set up, see hpr 1282

Still in the jig
still in the jig but all brazed up, top half of frame done!

More brazing to do
the next part will be modifiying the rear triangle and brazing it where i’m pointing to.


  • all in all, went better than expected, i’ll clean up those brazing joints after the bike is done and has been ridden for a while, before I paint it.
  • brazing isn’t as difficult as i thought it might be. give it a try its a cool hacker skill!
