Well if we’re getting into ‘jig support structures’, I just finished a new stand for the Anvil. Here it is with the old one in front. The old one was too short, not wide enough, bent, wobbly and got in the way when I was wheeling about on my office chair. The new one is based on the Anvil design (although I made it taller and a bigger footprint) and sits on double locking castors, is high enough off the floor that the wheely chair goes under the legs. It’s much more stable, easier to move, is much more out of the way, it’s even got somewhere for my allen keys and a pen pot! Brazing the 0.250″ wall box section was interesting, had to step up to a number 18 tip on the oxy torch, I normally use a number 3 for fillet brazing bike tubing and a number 1 for silvering braze-ons
I’m not sure whether this counts as something I made but I also did a repair on a Transition TR250 swingarm. The main pivot bearing bore had ovalised/worn to the point that a fresh bearing pushed in and out like a seatpost. I centred everything up on the mill and opened the 44mm bore out to 46mm so I could fit a bigger bearing
Testing the new bearing fit
The new bearing also had a larger ID so I made a new spacer that pressed into the new bearing to reduce the ID and maintain the spacing. I replicated the slots on the other side to make bearing removal easier in the future. Here’s the old bearing and spacer with the new versions
Once it’s all in place, you’d never know
