Hey Michael. Following your current build closely. (And the Demon build) What's the origin of the casting kit/plans ??? Is that a HM50/51 mill your playing with ??? I've got the HM52 H/V with plans to retrofit for CNC. Regards, Trevor, Melbourne, AU.

G'Day again Brian, et al. I seem to remember an article, I think it was Tom Walshaw in Model Engineer (happy to stand corrected), about piston ring and their wall pressure for various cyclinders. Went something like Steam - 6 to 8 PSI, Petrol - 16 to 18 PSI and Diesel - 38 to 40 PSI...

G'day Paul. Was wondering about you and your engine. Haven't heard of for a while. Good to know your still around. I have a few friends who, due to health reasons, had to dismantle their workshops (all tradies/toolies) and downsize. Must have been very frustrating for you as...

Still loving your work Mark. Keep going strong Mate. So glad you have covered the build in such detail. (Would be interesting to see how many "views" this build has clocked up. Angie, does the forum have a counter ???) And yes, you are correct, in ref to Georges drawings. An...

G'day Guys. @ Lukas Pils. Fully understand what you mean Lukas, and I do tend to round off as much as possible. Mainly for stock sizing etc. Having said that, I am constantly working in plus/minus dimensions anyway. @ dnalot. Mark, I'm rapidly approaching retirement so I'm...
