pin block repacement

[Fenton Murray]

Owen,
I'm sure your going to get some great replies on this that I'll read with interest. I think you could probably do what your describing below and be fine. Be sure stretcher is solid. You could get creative and re-enforce it if needed with corner brackets or gussets. Dowelling the new block to the stretcher/old block tenon remains ala S&S wouldn't hurt. Fall board cove can be done with a router or diagonal feed over a table saw, dry fit and test for clearance, a lot of times more was removed from the old block than needed and you don't have to make it look the same, a simple bevel will probably work. I guess I should have started by saying I haven't seen a Hardman apart that I can remember so I don't know exactly what you have. One thing I have done is plug and re-drill with good success. Here is a link to photos on a Bosey block plug and re-drill. http://www.murrayspianotuning.com/id192.htm
Good luck,
Fenton

  Hello list,

   

  I have a question regarding a procedure for removing a Hardman pin block. I have replaced blocks before, but this one appears to have been installed using a slightly different technique. While being doweled and glued to the inner rim shelf, there is also a mortise or rabbet under the stretcher that the pin block material is let into. The veneer on the front of the stretcher at each end, leads me to suspect that the block / stretcher were originally installed as a unit. Not really wanting to remove the stretcher, I'm wondering if I could simply cut the block out in the normal fashion (router and big bit), leaving the part of the old block that is under the stretcher intact and gluing the new block to that. This is complicated by the presence of a large cove cut in the bottom of the block / stretcher for fallboard clearance.  I'm hoping that some one has done this before, and can offer a procedure that has worked in the past.

   

  Thanks for any help at all,
