Paul: I'm certainly not an action guru but last year I did move a capstan line 6 - 7 mm forward on a Baldwin SF-10. It made a very nice difference. The DW had been in the high 60s and it came down to the low 50s and felt much better. Fortunately with that move the capstan was still in a good area of the wippen heel so I didn't have to cut the heels off and move them. dave David M.

Happy Friday! I am working on a 70's Sty B with a horrible action geometry problem. All the students and the professor hate playing it and I don't blame them! The line from key balance hole to wip has the capstan way too low making the DW close to 70g throughout. It has a renner action and hammers. the wips and capstans are such that I could relocate the capstans back by about 3-4mm. Would that make a big enough difference in the DW? It won't affect the line. I looked at raising the stack, but there isn't enough room to raise it more than 1-2mm. Should I try both? Also, is the measurement in Steinways made from center of balance rail hole on the top of the key, or from the back of the key? This is a new endeavor for me and I don't want to make things worse.
