[CAUT] Mason A Pics

[Paul T Williams]

Hey Jim and Jon,

This conversation helps me a lot!  I have a 1922 M&H "A" (same age as my 
Dad, so I understand it's "grumpiness)!!!) in the shop ready for 
restringing.  The angles look about the same, but a bit less % on angle. 
Yes, I think there might be problems in the thickess of the front rail 
cloth.  Mine is firm and hard, not all fluffy and thick as yours.  This 
might be part,(or all??) of the problem.  I had no probs with tuning 
stability, but lots of broken strings in the capo section, due to the 
practice piano syndrome.  I will be addressing the capo issue as well in 
this project, plus other stuff and corroded strings, dead bass 
strings....ya know, the usual stuff)

Jim, (OT) how is the down-weight/upweight numbers? Not having anything to 
do with the tuning problem, but my piano is waaaay heavy. That's a new 
issue, and perhaps I should bring that to a new topic.

But, by seeing these pics, if you can get much thinner front rail cloth in 
there, it may help a lot.  How are the agraffes? They might need replacing 
as well, or at least, need a drop of McLube...or something???? You might 
have a rendering problem in the front.  How are the bridge pins, bridge 
surfaces, back duplex areas?  Just more to look at ;>) 

Staying very interested in this project.

Paul

Jon,

I think you're right. You can see where the strings are actually cutting 
grooves. I'm just not sure what to do where the angle is so acute. (by the 
break)

Regards,
Jim Busby

This piano definitely needs a brass half-round or half-oval for the 
counter bearing.
The felt between that and the agraffes and pins only needs to be thick 
enough
to mute the wire and not cause drag.

I've done this to S&S's and Baldwins with good results.
