Head Case!

Standard

Well actually no. What we have here is a freehand sketch of the crank case, one side. The sleeve drive side (or timing side I suppose if you follow convention). To assist the pattern maker this view is quite useful. It’s also good for anyone wanting to visualise the finished engine.

The chain and sprockets driving the sleeve will be visible with the side plate removed. The side plate will house the oilways for feeding the shafts and the ignition pickup. I’ll post a pic of the side plate shortly.

Bob is finalising the full sized drawings, after which the design work will be all but complete. The only remaining task is to source a Piston and Sleeve along with a few extra parts. I’m waiting until I have those in my hand before I press the tit on the pattern maker.

Parts wise I’m waiting for people to come back to me regarding a special spanner to remove the Bristol cylinder. I can make one if necessary but I will still need to find a nut first! It’s a slow process…..

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!
