Hello, Thanks for responding, Yes I was asking about that feet problem too. I too have shimmed (wood) under the feet, but I am not sure If I was correct. Looking at the old action frame, the feet does not seem to be higher anywhere (but the rails are open). What I wonder is if the original setup when installing new wedges / new action frame, or new wedges / new keyboard is perfectly flat, what is giving the spring at the extremity of the keyboard ? Is the underside of the rail thinned at the extremity (did not mesure, I will tomorrow )? The rail show saw marks, so it is somewhat flexible. I am assuming we don't have to 'force ' on the extreme glide bolts (as for any one) in order to have the extreme of the key frame showing his play. Besides, I was told (by S&S techs) to make glide regulation without the blocks installed, that could mean that I will have these two extreme bolts a little lower, helping that springy contact between the front extreme keyboard . We try to have a firm contact there (under the front of key frame) so no play (no knock) will install himself with times ? Interesting idea to use minute Epoxy, Roger, do you mix some graphite powder or Teflon in this, I may admit I would be afraid of squeaks or absence of friction there, and minute epoxy is not very hard ?
