sp; I have a 1950's AA Mason that has one long bridge and 5 bichords on=
the bottom of it. I like the sound the bichords produce and the transition =
is quite good. I think your choice to switch to bichords a good one.</FONT><=

wonderful sounding piano with its original board. Great sustain &a=
mp; tone color. Phil Ford played it. I believe he enjoyed it! It's biggest f=
ault is the draft angle behind the agraffes which can be changes only by gri=
nding metal which I did on my Sisters AA. Its one serial no. apart from mine=
. They are very identical sounding. Too bad the agraffes are such freaks. So=
me one needs to make some. It seems Old Chickerings & per=
haps some others use something similar?</FONT></DIV>

p; The inside of the hole was so<BR>full of gunk that I ended up doing as yo=
u suggest you do, which is to<BR>enlarge the hole just slightly as well as t=
he countersunk area on either<BR>side. The hole is still a bit smaller=
than the normal new agraffe, so I'm<BR>trusting it will be okay. As i=
t turns out (for those following the agraffe<BR>thread), I was able to procu=
re a few 9/32" doubles from Schaff (from the<BR>old APSCO stock) which was r=
eally all I needed. I wanted to change the<BR>scaling on this AA sligh=
tly, substituting bichords for the trichords on the<BR>transition bridge so =
I needed only about 6 doubles. This all happened in<BR>conjunction wit=
h recapping the bridges. Of course, I went ahead and made<BR>all=
the changes before I bothered to pull the agraffes only to discover the<BR>=
odd size of the shank. Had me sweating for a bit. Seems that it =
will work<BR>out. Did we learn something here? You'd think I'd h=
