alex_holden Posted November 22, 2015 Share Posted November 22, 2015 What is the reason for bellows commonly being inset slightly? For example on my Lachenal the end boxes are 6 1/4" AF but the bellows are approx 6" AF when closed. Is it just cosmetic or is there some practical reason that I'm missing?

Chris Ghent Posted November 22, 2015 Share Posted November 22, 2015 I made one with no rebate once; worked perfectly but did not look right. If there is a good practical reason not to do it that way Geoff Crabb will know it. Link to comment Share on other sites More sharing options...
Geoff Wooff Posted November 22, 2015 Share Posted November 22, 2015 (edited) Would it not naturally occur when fitting the hinge of the first folds to the wooden frames that there is a drop, or height gap to stop the inside of the card pressing or chaffing on the wood or straining the leather hinge ? After all the last card is generally chamfered and relieved at the corners so as not to impede the opening and closing action. It does look neater and stops the top runs rubbing on any surface the concertina is placed on, including the cloth of one's trousers, or dress if played with the instrument on your leg.

David Hornett Posted November 22, 2015 Share Posted November 22, 2015 I have made equal amount, 5 inset and 5 flush, simply by mistake (I cut 10 lots of bellows cards to length and then not thinking reduced the concertina frame to 6", too lazy to recut the bellows cards (I did not discover my mistake until I had begun making one of the bellows) I fitted one, seemed fine so now have 5 flush bellows. No noticeable difference in performance, but the bellows are not as protected when the instrument is put down. David Link to comment Share on other sites More sharing options...
alex_holden Posted November 23, 2015 Author Share Posted November 23, 2015 Thanks. I think I'll inset the ones I'm making now because I prefer how it looks. Good to know that they would still work OK without it though. Geoff: I think I see what you mean, the inset makes it easier to ensure the hinge can't foul on the corner of the frame.

Yes I think that is what I mean. There is quite a bit going on at the frame corners and the traditional design appears to allow space for the parts to fold in without interferance . Good luck with the bellows making. Edited November 23, 2015 by Geoff Wooff Link to comment Share on other sites More sharing options...
Jake Middleton-Metcalfe Posted November 23, 2015 Share Posted November 23, 2015 I was told that it is so that the bellows themselves don't touch the table when the instrument is put down thus reducing wear (as well as being a visual thing). Different makers seem to do it to different degrees from what I see, Marcus music bellows are not that inset and still look pretty good imo Link to comment Share on other sites More sharing options...
JimLucas Posted November 23, 2015 Share Posted November 23, 2015 I was told that it is so that the bellows themselves don't touch the table when the instrument is put down thus reducing wear... Also protects the bellows folds from any liquid spilled on the table, no? Link to comment Share on other sites More sharing options...
