Crowning one rib at a time

[Richard Brekne]

Hi Terry.  Yes, tho you used pneumatic presses yes ?  Just comparing 
notes really as usual... you know me :)  So far, I like the looks of 
those aluminum bars that David Love came up with best... tho I've yet to 
try ribbing my own panel so its hard to say what the experience would 
point me towards.  First time around I suppose I'd be all worried about 
the ribs slipping and sliding around and would want some fix idea for 
how to dead on prevent that.

Finnally getting the French Polish on that Bluthner finished.  I got so 
much <<standard>> work to do all the time I never get the time to finish 
the darn project.  Action got finally re-furbished this summer.... tho I 
still am unsure as to what to do about the keybed falling away just 
under the front rail.  I have for the time being a rather thick piece of 
spruce shimming tacked on under the front rail of the action to make 
solid contact so essentially the keyframe is bedded well enough.  But 
really the keybed should come off and be replaced.

I suppose at some point I'm going to have to decide to jump in with all 
fours into rebuilding (which I actually do enjoy immensely) or leave it 
and stay on concert prep & tuning work and action rebuilds... which is 
very profitable and enjoyable as well... ahhh... always some annoying 
choice thing out there in front of you... :)

    Richard - that's basically how your Bluthner laminated board was ribbed.
