  1. Hi, This Christmas, a friend’s dad gave me an old Lachenal 30-button Anglo that had been in his family for generations. Unfortunately it is in a pretty sorry state, but as an aspiring musical instrument restorer, I have decided to have a crack at mending it myself (with the help of our friend's tools and DT experience). It is a beautiful instrument, with hardwood ends and bone buttons, steel reeds and a 5-fold bellows. As the photos show, it is a bit dirty (nothing some good cleaning can’t handle) and has had the bellows poorly repaired in the past with what looks like plasters…? Ins
  2. This is a naive question about tuning! I'm looking at an old bandoneon that needs only spot tuning. Nobody local can really do it. I've tuned a couple of the outside reeds myself using the demo version of Dirk's software with pretty good results. For the inside reeds, I definitely need to remove the reed plate so it's more complicated. Presumably, I need a bellows, or even a table. I don't really have a shop or space to make one, other than kitchen table, so I'd have to purchase this. So I'm wondering is it possible to tune reeds without a bellows by twanging them on a resonant box like a tu
  3. Once upon a time, the accuracy and precision of tuning was all done by ear. I think we can all agree on this. The accuracy was determined by the accuracy of tuning forks and how that was transferred to master reed sets. The precision or repeatability of a tuning being down to the skill and ear of the tuner. When I first started in this game, I tried different meters, and looked for accuracy and repeatability in readings, I also looked at discrimination of displayed values, so if I was trying to tune to say +/- 5 cents, I needed to be able to measure at least 1/5th of the spread of the
  4. I'm tuning a 30 key lachenal at the moment, and having some trouble with 2 of the reeds on the top row right side - I keep trying to sharpen them but it gets flatter. Both are long enough that it's not because of filing in the wrong place by mistake. On the charts I've seen, both should be d# in a lachenal, but the ones in mine are both eb, I don't know if that has anything to do with the problem. ANyone have any idea why this might be?
  5. I am trying to patch up an old Chemnitzer. Using a good tuner, I find that it is on average between 340 - 380 cents below current concert pitch. Is it possible to tune to the reeds up to such an extent?
  6. I've been learning about tuning reeds, by embarking on retuning a brass-reeded Lachenal tutor to concert pitch from old philharmonic pitch. I bought it as a wreck some years ago and have been restoring it intermittently - see lachenal_52313.html. I realise that retuning is hard, and tedious, and I'm likely to make mistakes, but I'd prefer to make mistakes on this instrument which will never be a great one. A famous physicist once said that an expert is someone who has made all the possible mistakes in their subject! I've done a first pass on all the reeds, and now doing a second pass. It'
  7. Wondering if anyone has a good suggestion for an air pump for tuning and playing with reeds? I saw an earlier discussion that more-or-less concluded that an old bellows was the way to go. Probably OK for tuning, but I also want to do some experiments with reeds, and a constant-flow, hands-and-feet-free system would be preferable. Ideally quiet so as not to interfere unduly with measurements and recordings. Desirable to have suck and blow available. Don't want to spend a fortune though. Any bright ideas? Good to know too what people have tried and how well they have gone. Nice to kno
