I agree. Not necessary.

As well as being over 1/8" (3mm +) in thickness. (btw, a good argument for thick reed plates) lol.

I would think it would take a 'press'.

And that would be disastrous. Given the high cost of these instruments.

Oh, certainly not. And you have given the answers I was hoping for. I wasn't certain. And I don't like being uncertain.

I did some repairs myself and on one particular Detroit made unit (I forget the name), I made a new reed plate. I cut the tapered slots out by hand, and finish filed them to size. I used road sign sign board aluminum...softer than standard plate stock. After I was done, the tone on one of the reeds was too soft, so I embossed the draw slot. The reeds themselves were made from steel from the return spring from a 'Marchant' calculator. It worked. I charged $35.oo
