Big wheels keep on turning.


With work on the conrod finished for now, attention turns to the flywheels. The slices of big bar fit into the 4 jaw chuck on Bob’s lathe, which is handling the job nicely so far. Getting the tough outer ‘crust’ off the steel is hard going, light cuts are needed and plenty of cutting oil.

It might not be too healthy, but it smells great!

There’s a fair weight to each wheel so it’ll be a weighty engine, maybe a 2 man lift. Then again so is a GPZ900 so I’m not too concerned.

We can’t swing the conrod though, even on the big lathe. It’s 14 Inches and the lathe will spin 12, so some thinking is required to finish the eyes.

Anyway, small progress is still progress:-)

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!
