I then cleaned up the bore and started work on the waterspace. I was about half way through and all appeared to be going well. Then I noticed a change in the sound of the cutter. I stopped the machine to check what was happening. My homebrew digital readout made from a tyre depth gauge had somehow shifted and I had cut too deep, so deep in fact that I had parted off the top of the cylinder from inside! :doh:
My immediate reaction was that was the end of this motor, but after a little thought I realized that this may not be a catast.... catastro...... problem. Having the cylinder in two halves means that I can machine the water space more accurately and then make a spacer to join the two halves back together. The cylinder is going to have a cast iron sleeve anyway so it should all go together ok.

P.S. catastrophe

Oops !

Glad to see that you've found an upside - give me those positive vibs  :lol:
vtsteam:
Aha, Plan B!
NormanV:
I've decided to give up on this engine, at least for now. There are just too many unknowns, I will keep the patterns and maybe later I will try again.
awemawson:
Come on Norman, that's not the spirit that got you to the Falklands and back - dogged determination needed  :clap:
