Perhaps you could go the other way. Glue a tiny frame of wood around the reedhole in the reedblock and put the reed on top of it.

My wife uses a tiny electric drill for her jewellery making hobby. It has a lot of applications, including small grinders of different shapes that can me used to do shave of your reedblock. Almost like at the dentist :-)

John,
I'm not completely sure I understand the problem.
Is there any reason a little accordion wax would not solve the problem?

I've used wax to fill in some really nasty holes and gaps in cheap accordion reed blocks. (I'm not saying your accordion is cheap, BTW :)

I would send it out for repairs, jim.

Try moving the reed over to the opposing side so that the tongue has room to vibrate. If that makes the pull reed hit the other side then the chamber is too small and the blocks were not made right.

I have a feeling the chambers were made smaller to for better compression. It's only one chamber that is to small.

Thanks for the advice, I'm thinking of stacking more wax to raise the reed a slight bit. I never thought of this.

Thanks again
