I still have pretty much the whole thread as it's a = long one and I haven't sorted through it yet to see what I want to save. = Keith Roberts ----- Original Message -----=20 From: Piannaman@aol.com=20 To: pianotech@ptg.org=20 Sent: Saturday, July 05, 2003 8:43 AM Subject: Re: V-cap update Hi Ric,=20 Back in pre-convention days when I was getting 8,042,957 messages a = day, I admit to not having read each and every e-mail in the v-cap = thread, so I probably missed some key bits of information. I aplogize = in advance for asking questions you've probably answered more than once. = Where are you doing this experiment(s)?=20 What kind of piano/action are you using?=20 Thanks,=20 Dave Stahl=20 In a message dated 7/5/03 3:29:23 AM Pacific Daylight Time, = Richard.Brekne@grieg.uib.no writes:=20 First... you want to buy a few small neodym magnets... you'll be = amazed at the difference in power... little bitty things can push 50 = grams no problem at 5 mm..... a neodym 40 mm across and 10 mm thick can = lift 50 kilos.... Anyways... as to your question. Epoxy or CA glue. They = recommend CA. For the whippens I countersunk the magnets and glued them. = For the keys I am going to sink them (and glue) in a small letoff button = that has a drop screw inserted through. The drop screw will then screw = into the shank thats pinned to the key. For experiments tho.. the = neodyms will stay put just on a steel screw, where as the kitchen = magnets probably wont. Order a few in the size range =D83 - 5 mm = diameter and 3 - 5 mm thickness and fool around with them. There are = perhaps several ways of employing these usefully in the action. One = thing I heard suggested was to put attracting magnets in both the = capstan and whippen cushion to form more of a solid coupling between = those too... just a thought Cheers=20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
