<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Hi David I havent gotten my July Journal for some reason yet. But I imagine the Velo article is about his idea up on the hammer shank and rep lever. We had that article in the last number of the European. As far as weight of the assembly is concerned. I have figured out the net effect, and Ron Nossaman provided a very cute method of figureing this out as well. I need around 15 grams of effect between the two magnets (whippen and key magnet) and I can get close to 60 grams at 4 mm seperation. Put in terms of DW, I can reduce DW by 10 to 12 grams down weight with the magnets in the picture without causeing any noticeble problems. Actually, I am nearing completion of the first full action install. But in that I have simply routed out a channel for the magnet shank, pinned the key, and installed the magnet shank. Useing a premade assembly would be faster and neater. But I need to know what kind of wood would be best to use. Cheers RicB     "David M.

If one was to cut out a section of the key to put in an assembly like my keymagnet assembly, what king of wood type would be  a good choice to use for the assembly. It needs to be hard enough to facilitate a center pin that holds the magnet shank. <img SRC="cid:part1.3F0F3710.C76FCA2@grieg.uib.no" height=204 width=350> Thanks RicB -- Richard Brekne RPT, N.P.T.F.
