(back) Subject: Console progress From: <> Date: Sun, 26 Aug 2001 00:00:30 EDT   Very happy to say that I found on the wood some very faint soft pencil = marked names for each of the sliding contact rails, very hard to see but I can = make out; sw uns, 16, 4 etc. So I now have the Sw Unison contact rail wired to the junction board to = start with. I also decided since I have the manuals out, to examine and clean them. I wound up replacing the hammer rail felt and the key tail felt squares = and adding a bushing cloth disk on top of each of the balance rail felt disks since they seemed to have settled down a little and there is also an excessive gap between the key tail felt pads and the underside of the = spring loaded contact rods of about 1/8th of an inch.   Now cleaning and oiling the keys with a solution of gum turpentine and linseed oil, about 25% linseed oil 75% turpentine. Also McLubing the pins. Looks like several of the bottom octave Sw sharp keys will need new = bushing cloth in the balance pin holes, real wobbly! Next I'll have to order some plastic buttons to replace the rotted leather = nu ts, and I also need 4 of the phosphor bronze coil springs Moller used that =   were soldered onto the ground wire and to the phosphor bronze contact activator rods to act as the electrical wire and the return spring. So far = I have not found either on the OSI web site. They keys also had excessive travel, no doubt due to the bad hammer rail felt, I understand the edges of the natural keys should depress 9.5 mm/ = 3/8" is that correct? What about the sparp keys? And what is the AGO standard "weighting" for the manual keys? Back to cleaning I guess, so sign me;   A very pine scented Randall
