Thirst quencher

Standard

Well not really. Much as this looks like a cool cocktail, it’s the sleeve drive pin being quenched. The whole jar became too hot to handle, so there was plenty of heat in the pin. Rock hard! Now to temper it.

When it had come to a reasonable temperature, we gave it a wipe and warmed it up again – this time to a dull red. From there into the oven at 200°C for an hour, before allowing to cool slowly.

Next up, it grinding to size on the cylindrical grinder.

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!
