The machining on the liners was completed, the insides bored to dimension and the valve chest outsid was roughed and the slots for the steam passage was machined. The outside of the cyclinder liner was machined only to allow a clean surface to hold in the lathe chuck.
Then the Cyclinders and liners were send to a professional honer to hone the Cyclinder and valve chest opening to be the same and parallel. The liners were also honed to be the same and parallel. The honer achieved tolerances of less the .0005 on the liners.
