When you drill for the new capstans drill all the way through the key. Then use a size-on-size pin on the table to index the key below whatever ram you are using. To drive the capstans home use a bolt (or whatever) with a hole just larger than the capstan--to facilitate quick locating--to keep the capstan straight while driving it home. ddf Delwin D Fandrich Piano Design & Fabrication 6939 Foothill Court SW, Olympia, Washington 98512 USA Phone 360.515.0119 Cell 360.388.6525 del at fandrichpiano.com ddfandrich at gmail.com -----Original Message----- From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Brown, David Sent: Friday, September 28, 2012 10:30 AM To: pianotech at ptg.org Subject: [pianotech] Capstan installation All- Great question Ed . I am changing the subject to ask what methods are used to install capstans after determining the proper placement? I have tried various ways and have never been completely happy with the results . Pressing them in with a drill press after drilling and chamfering the hole worked best, but still difficult to keep things from leaning in different directions in the soft keys. DB Greetings, I think this would be a good time to hear from those that can distinguish between actions with identical ratios, but different knuckle distances, (which, of course, infers that the capstan placement is different.) Is there a difference between an action with a low key ratio on a 16 mm knuckle distance and one that has a higher key ratio on a 17 mm knuckle distance? regards, David C.
