A new workshop, a new chapter..Posted: May 6, 2013
I decided to set myself up in a workshop nearer to my brazing job at the Brompton bicycle factory. The building is an old boatyard on a small island on the tidal Thames in west London.
I thought it was about time that I bought myself a decent torch.
In my day job as a production brazer at Brompton, we use injector-type torches which are great for use with gas fluxers as they really help to push the braze forward and shape the beads with their added thrust. I believe that my Harris torch here is what is known as an “equal pressure” torch, which gives a slightly gentler flame that’s easy to control and should be good for making smooth concave fillets.
I’ve also decided to restore an old Honda CD200 motorbike as a project so that my commute to the bike factory and errands to and from the workshop might be more practical. Sorry if this appears off-topic, but I was without a workshop and a torch for a good few months..
The countershaft was worn where the front sprocket mounts, so I thought I’d rebuild the engine and replace any other worn parts, seals, piston rings, etc.
The swingarm on the bike was pretty rusty – after shotblasting it looked pretty sketchy so I cut away some steel to reveal the extent of it all. I found a big hole in the tubing inside:
I found it impossible to find a replacement swingarm that was in good condition, and so I bought a used but rust-free US CM200 Twinstar swingarm which is very similar, but I’d have to swap over the driveside fork end (my bike has a bigger spindle to mount a cush drive) and a few other small mounts for the chainguard, etc.
I also decided to remake one of the welded-on plates as the rustworm had made it pretty flimsy:
I promise my next post will be purely pushbike related!
Bye for now,
