>..Dear List: > >..i have in my posession a DH Baldwin action..customer is correct when she Check to see if the capstan line is parrallel with the key fronts and that the contact point of the capstans on the wippen felt is consistant from end to end. If there are three or four leads in the keys already you have a leverage problem which needs to be corrected. Check the up and down weights. Lubricate everything carefully with dry lubs and recheck touch weights. Check pinning, key bushings, wippen pinning. Shim one wippen out about a half or whole mm to see if you get an improvement of touch weight. The object is to find a shim distance that provides the smallest difference between up and down weights. If there is an improvement you can change the spread action measurement for improvemt. If the distance does not improve the spread action is not the source of the problem which may very well be capstan location. Make a small block of wood with a capstan in it and remove the capstan from one key. Place the block under the wippen and use it to determine if an improvement can be had by moving the block fore and aft. At this point it gets complex. Relocating capstans is a very precision operation requiring familiarity with action leverages, mach, and machines to do the work. At this time it would be well to contact David Stanwood for procedures since this is one of his areas of expertise. Newton nhunt@jagat.com
