Main Bearing Bore Finished

Standard

The main bearing on the timing side has been bored and that happened in no time at all. As per the YouTube videos, using the CNC control to start/stop the motor and feed the cut makes these bores quick to do. Even Bob was able to drive the machine and complete the operation.

All of the bores on the timing side are done now, so the next job is to fit the drive side without removing the timing side from the mill. The dowels will ensure that the cases go back together in the same place, so that the two main bores for the crankshaft to run in are completely concentric. (In theory anyway!).

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!
