I've got a set of pushrods that are too long....they are good Manton ones w removable ends, and they can be safely shortened upto .015....I've recently ordered a 12 inch dial caliper and gotten a ball bearing....to accurately measure them. I understand if I heat up the end of a pushrod tube, the end should pull out reasonably easily, then I was thinking I could chuck them in my drill press and push down against a grinding stone to shorten them. Does this sound like a workable plan? Any suggested ways to do it better? Does it matter which end I do this to?

Thanks for any and all help
