A Vegan Concertina in Instrument Construction & Repair Posted March 29, 2016 Thanks all for your lovely and encouraging comments. Nicx66 the birch bark is a great idea, I am planning some not necessarily vegan, but more "natural" instruments that this would work well with. Also thanks for making an old post hot again with your mis-post! Jake of Hertford, thanks for your interest, I've applied to join your fb group if its still active. Bellows fabric is made with a layer of cleaning cloth, skived to nothing with the addition of "iron on" interfacing material and a coat of heavy body acrylic and acrylic medium mix. The resulting sections are much harder to stick than leather (to put it lightly!) but function well. The problem with synthetic chamois (PVA cloth) is that it becomes quite rigid when dry, so you need to really work the folds in, which has worked in this case. The latex coated cloths are probably a better bet as they remain supple when dry. In both cases, I've found that the synthetic bellows are momentarily stiff when taking the instrument out from cold, but loosen up well within a few minutes of playing. Just found this from french speaking canada, accordion equivalent perhaps, looks nice- http://www.eco-rdeon.veganquebec.net/wonder if they have the same issues with synthetic fabric bellows Mike Franch, I think you asked me this before - short answer this time is I'll try and make an English if someone asks me too I may well be making a Hayden for someone at some point too! Production? Pass, would have to give up the day job! Stephen Chambers, interesting you bring up the rexine example, my first attempt at these bellows were weak at the valleys, I had only used the interface without the cloth as was concerned it would be overall too inflexible. This time I worked out a method of using the full ply, and used a clamp with an embedded plastic wire to "bed in " a good fold in the otherwise too thick material. The nice thing about these bellows over leather is that if you get in a gluey mess (as I did on occasion) you can just wipe them down and put another coat of paint on! ..and thanks CG!
