a lovely solution to the problem there Chris :thumbup: :clap:
cheers Graham

I would suggest you stick to the plans, and you will find that the the figures are almost the same as that person is showing.
Blackgates stock Viton o-rings, but I don't know if they do imperial. You will require, for a 7/8" (0.875" bore), a 3/4" (0.750") bore o-ring with a 1/16" (0.0625") cross section. The depth of the grooves in the piston give the correct wall pressure, so stick to what is shown on the plans, and if too much friction, you can always skim another couple of thou out.

Thanks for the advice. Just curious, what is your opinion on going with a CI piston, close fitting with no rings as Nick suggested. I did consider this but guessed there must be something wrong with the idea but looking at Jan Ridders plans for his simple IC engine, like Nick said, he uses this method. Or do you think O-rings best option?

Do it the way Bogs say. Alu. piston and viton O-ring. Regarding the piston. stick to the plans and you will be rewarded :head I used the Alu/O-ring on my Webster and it have been running for X numbers of hours and still have the same good compresson.
Keep up the good work :beer:
Best Regards

OK - thanks for that confirmation crankshafter. I will certainly go down that route. Thanks for the reply, always good to hear from people who have made the engine!!
