You should be able to correct excess friction in the keys in about an hour, and possibly have a little time left over to adjust the capstans. (Which, BTW, could be adjusted too high and cause sluggishness.) Get into a system -- do it methodically throughout the whole keyboard. Check and/or do the bushings first. It's handy to have one of those tools that allows easing front rail bushings without having to completely remove the key from the frame. You could check the balance rail bushings first, then check front rail bushings. Then go through and check the balance holes. If you do that systematically, it's much faster than trying to do them one at a time. -- JF -------------- next part -------------- An HTML attachment was scrubbed...
