    I've said that to a few women in my day, but it didn't get me anywhere!

    Machining the piston pushrods in a reasonably free-cutting stainless.

    I had already made a set of piston rods before these, and machined up the cylinder cover to size. However, I had a problem when machining the crosshead to accept the rods. It was a blind hole and the centres had to be spot on or the whole thing would bind. The holes were 9/16" and about 1" deep: tight for a boring head. I purchased a long series endmill for the job as the best way forward. I made the error of leaving the endmill with too much material to remove and it wandered slightly, making the hole .008" oversize. There were a couple of ways I could have rectified the problem; my choice being the longest way round and re-making everything to fit the oversize holes, including new pistons.

    You took the same approach that I would have to fix the over size problem! I hate a job that has been patched up!
