Just a quick update again, as I have to jump on the lathe in a moment, more of a quick snap for Brian, as he’s got broadband now!

The first trial fit on a crankcase went exceptionally well, as the cover fits snuggly with no discernible play on the locating dowels.

There were two minor issues, one the oil light piston tab washer detail was slightly too small, and two, the O ring seal could be marginally tighter on the sensor holes, but all these have details have been corrected in the 3D model now, so the rest of this batch will be spot on.

I am extremely pleased with the results so far, and even better, there is sufficient room for the various trigger wheel configurations I have planned.

I will update the pictures again later.
