  • Yeah, grinder is used to chop out the holesawed sections as obviously the holesaw will bottom out, so it's holesawed out in stages. :)

    Set up once in the mill for both top and downtube, saw cut saw cut saw cut, done.

  • I’ve wondered about doing it before but would need to cut it all by hand.

    I have a plan where I could do a relatively straight cut on the top and down tubes and then sleeve some larger tubing over and mitre it to the new headtube. Would allow stretching of the frame as well as making cutting the mitres easier.

    Sort of used a similar technique when I built this...
