	The inside of the cylinder in a steam engine gets a lot of wear and tear, largely due to friction from the piston rings, but also from corrosion and scale build up (impure steam). Cylinders left idle for long periods may also rust and pit. For these reasons, the cylinder is built with a removable liner, sourced from an auto parts dealer. The current engine design calls for a 4.0" bore. The sleeve is 6.0" long.

Cylinder clearance is 0.250".
We will use 3.6" from T.D.C as the left edge of the exhaust holes, which shall be 0.25" in diameter.
As such, the exhaust holes are centered at 3.975" from the cylinder head.
