This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Thanks, Wim. Actually, these hammers were incredibly worn and smoothly flat as the flange bushings had all failed. The rest rail felt was more dirt than wool and deeply grooved and worn. So I made no attempt to measure blow. You are right tho, and I sure should have measured key height, although that wouldn't have been accurate either--the felts were all bug-eaten, the paper was mostly missing, and the keyframe was completely full--and overflowing--with dust and who-knows what else. *It was horrible. This job was not so much a rebuild as a resurrection. I actually tried hard to discourage the client from doing anything!

I won't have any trouble getting a good-looking and good-working key height based on keyslip, nameboard, and available dip but I have to settle on a blow distance before going further. The set-up, with new parts, is about halfway between 1 5/8" and 1 3/4" Does yourall's (I made up the word) experience think that is good enough or should I rip out the rest rail felts and re-shim it .... and if so, should I go for 1 3/4" or 1 7/8"? Is there a simple way to decide this, or do I need to completely regulate 3 or 4 keys before I know it will work? One other factor, maybe not too relevant to the discussion. It has long, tall dowel-capstan type stickers. Alan Barnard Salem, MO Alan Before doing any kind of major rebuilding like this, you HAVE to take measurements of what's there, even if you think you can improve on it. But since you didn't, most older uprights had a blow distance of 1 7/8". Start with that, and see how everything falls into place.
