Hello

I have been looking for a guide or fomula to calculate the clearance between the piston and the cylinder end caps. I have had no luck in a internet search. The cylinders in question are form the Stuart Turner Victoria 1" bore x 2" stroke, but being using in a vertical boiler steam loco.

Any ideas where i might find the imformation?

Thanks

William

Hi There

You don't need a formula.

Length of cylinder – depth of recess on both cylinder covers – thickness of piston.

Divide by two and that is the clearance to leave at each end.

Assuming you have the drawings.
