  1. Peter Have a look at this website. Section 8. There are a number of Australian makers and repairers listed http://www.concertina.info/
  2. Hi Seth I have finished the bellows, apart from new chamois for the ends. They have compressed down quite well but are tight - you have to use some effort to open / close them, and they don't open as far as they should. They certainly won't fall open at the moment. I don't know the reason, other than they may have been left to dry too long on the jig after the top run linen was glued on. I used hide glue for the linen, and it is possible I used too much or it was too thick? For all the leather work I switched to rabbit glue as this was being recommended by some expert makers. The previous period of compression I gave them just prior to fitting the leather did the trick in bringing the size down, and when I I put them back under compression they will be shut tight when I take them out. The attached picture shows them in their current 'relaxed' state I am exercising them daily and once the ends are fitted they will go back under compression. I am hopeful that with use the tightness / springiness will reduce. Regards Rod .
  3. Larry Can I refer you to your post from April 16, 2019 on this very topic? Rod
  4. Have you thought about the kit available from Mark LLoyd-Adey at Concertina spares?
  5. I've had the bellows in compression for about a week, on and off, and it seems to be doing the trick. They have reduced in length considerably to about 6 inches, with a little springiness left in them. Once I have fitted the top and end runs they will be going back under compression. Thanks for all the help. Rod
  6. Chris Thank you for this nugget! I had anticipated a couple of days, but this comes as a complete surprise. I don't remember reading anything about such a long period. Another example of how little I know. I can understand your 'in service' comment more easily they will be kept under compression.
  7. RAc Unfortunately I didn't take pictures between fitting the bindings and the gussets. However, I have taken on board your suggestion that the bindings may be contributing to the problem. So I have tried an approach to relax them a bit. I have moistened them all slightly with a damp sponge (they are not wet) to introduce a little moisture, and put the bellows back under compression After a couple of hours I removed them, and found that the amount of spring back has reduced significantly. I will re-compress and leave the whole assembly to dry fully, then see what I have. Fingers crossed. Regards Rod
  8. I am considering removing the end frames before compressing. Some of the joints have burst in the previous compressions, so repairs seem to be in order. I should be able to get better access to the troublesome parts with the frames out of the way. As for the gussets, they were skived down from 0.5mm to nothing at the edges, Perhaps I used too much , or too thick, hide glue. So much to learn!
  9. Alex You are right about the size of the angle between the cards.I have been following Bob Tedrow's method, which suggests an angle of 55 degrees for the sides, so assuming the angle of each corner is 60 degrees. I make it that the angle between adjacent cards is 10 degrees (2 x 5 degrees). Two other possible factors are - the lambskin hinge in the valleys fitted when the cards are still flat, skived to 0.5 mm, possible a little thick? - the card itself is rising-museum-board-4ply-16x20 @ 1.52mm, again possibly too thick. Bill I too have made some of those hexagonal blocks from a previous job, so I can try your suggestion. All the compression so far has been from outside the end frames Then continue to conclusion and see what I end up with. Thanks for your replies Rod
  10. I have completed installing the gussets, but now have another issue. I have taken the bellows out of the jig, and find that they are now acting like a spring. The bellows were compressed before going into the jig , and closed pretty flat. Now, after exercising them a bit I find they only close about half way unless I exert more force that would be expected during normal use. When I do close them, they spring back. I have not fitted the end or top runs yet. I have attached a picture of the bellows in their relaxed state. 😞 All the other instruments I have close under their own weight, so there is obviously something amiss. Could I do anything to relax the bellows, or are they lost cause? If so I am happy to put it down to experience and start again. I want to get them right before refitting the reed pans and action boxes. Many thanks
  11. Do any of our members in the UK offer practical help with learning the specific leatherwork skills needed for making concertina bellows? I for one would be interested. Rod
  12. PAAUDIO Thanks for your response, one for the future perhaps?
  13. I have got my leather strips down to 0.5 mm (with some help )but am struggling with the edges. If I use a knife or blade I am struggling to keep the edge straight. I am assuming they need to be as straight as possible. Any advice?
  14. Thanks Chris. Yours and Alex's advice is much appreciated The outer hinges are now done, bring on the leather! Rod
  15. Alex, thanks for your reply. I just thought you may need to make sure the last peak was secure (as the remaining 5 are) before putting the cloth on. I can rest easy then, because this was proving very tricky. I will go ahead and fix the cloth Regards Rod
