Not got much done this week as work was a bit hectic a load of senior managers getting 'moved on' and my business sector getting merged with another...
Despite it being adequate, I really didn't like the first integrated bearing headtube I made, so had another crack at it early in the week:
Changed the way I was machining, got all features done to then part-off and be left with just the lower bearing seat to machine in a collet chuck so it was concentric:
Also got to play with the proper tooling for the critical dimensions:
= one finished headtube that I like (other than the crap finish in the centre but that'll be brazed/welded to anyway)
Also went for a forum favourite and matched a 'slam that stem' cover to the headtube:
To make a completed unit I'm actually happy with:
And i now have tubing on order:
-3m x 40mm OD 2.0mm wall thickness for the spine
-3m x 1/2" OD 1.6mm wall thickness for fork legs
Also i drew up some fork crown plates, got them programmed into the CNC mill to be done next week now:
Was going to get the spine formed and order the wheel this weekend but forgot I was riding Mountain Mayhem, so I'll have more information as soon as I get cracking again
