Hey there David. Nice to have a Touchweight question up again. > David Love wrote: > > So here's a question for all you action geo-philes out there. I'm > replacing a set of hammers and shanks.

Thats pretty low friction allright. Tho 50 grams DW is usual enough. > When I replace the shanks the friction will go up by probably 3-4 > grams in the center.

Just a thought David.... what makes you think (not that I am saying you DO ... grin) that she is not refering to the lack of shank friction ? > Will she be happier with a 42 balance > weight and 53 - 54 grams of downweight where it was once 50, or will > she be happier with a reduced balance weight that yields a similar > downweight with the increase in friction? > My advice would be to avoid overdoing the change in hammer shank friction and try and compensate any difference with action lubrication otherwise.. ie key bushings, etc. I've seen this before. Do your best at everything, tighten up those flanges so the hammers deliver that nice solid blow on hard play, go out of your way to keep DW the same and the customer "feels" a gigantic change somehow. > Something else to think about. > > David Love > -- Richard Brekne RPT, N.P.T.F.
