One of the things I ran into recently reading dealt with this a bit me thinks.. As I understood the article.. one of the things to be concerned about was the distance the roller was from the center. The farther away it was, the larger its rotational arc... ergo the more slipage on the repetition lever. I have to look at your action yet.. but I wonder if you might comment on this ? > > > Regards, > > Ron Overs > > -- > > _________________________ > > Website: http://www.overspianos.com.au > Email: ron@overspianos.com.au > _________________________ -- Richard Brekne RPT, N.P.T.F.
