Now, I may be wanting to replace the valves on his anglo concertina sometime, and also this question applies to accordions, too. What glue do you use? I ask because, on all the old accordions I've worked on (I don't think I've ever owned one less than 30 years old), some of the valves often come off just with a touch (such as you have to do when tuning), or are already off. These have been put on with shellac, which I have seen recommended for use even today on one accordion site. Now, I've found this shellac very brittle, but worse, the reed is always very rusty right behind where the shellac is. I don't think that's a co-incidence, I think it's because there must be water in the shellac.
Now, Bill's concertina's valves are not glued on with shellac - I don't know what it is, but it doesn't seem to be shellac. What do you guys use? My original teacher taught me to use Quick Grip, or any contact adhesive. That can be very thick sometimes, though, and sticks really well - sometimes too well, when you want to remove it again for some reason.
Sorry for the garrulous post. Any advice on this?
