I'm replacing the pads in a Lachenal 48-key English concertina but aligning the pads is driving me crazy!
Despite the embossed circles around the holes on this concertina being poorly-formed and in many instances not concentric, I've managed to get the pads sitting centrally over the holes. However, when I try to position a lever and its little leather bead on the pad, the tendency of the lever to flop sideways without the support of the bushed hole in the fretwork throws everything out-of-whack!
I tried making cardboard jigs to hold each row of keys vertical but with limited success. I can see no way around the problem other than making a complete bushing board as used on metal ends. Does this mean it's time to replace the action plate due to excess wear in its holes? I've searched David Elliott's book and Concertina.Net for guidance on this all to no avail. Am I missing some crucial step?
Any help appreciated.
All the Best
