Red hot


Phase 1 of hardening the sleeve drive pin is to get it to a bright red heat. The butane blowtorch I tried wasn’t enough for the job, so I I bought a butane/propane mix. That was much better and with a few bricks around to reflect the heat it was soon glowing.

The photo looks like a space raygun about to vaporise something. Maybe I watch too much SciFi?

Next to quench it in oil.

About Sophie Whiptank - aka Bart

I'm just a bloke doing some stuff, the more interesting bits I post on my blog. Scroll down far enough and you'll see me riding from Melbourne Australia to Birmingham, England in 2014. But now I'm working on another project, a single cylinder motorbike engine at 2750cc!
