Mike Pierceall Posted November 15, 2014 Share Posted November 15, 2014 Some photos of a simple bellows frame I constructed from odd scraps of wood. The inner core of the armature is built up of thicknesses of wood glued together and then then cut to dimension on a table saw. I then tacked shims on the facets to bring the frame up to match the inner dimension of the bellows when fully expanded. In this way it can be adapted to fit various sizes.

david robertson Posted November 16, 2014 Share Posted November 16, 2014 Having built something similar a few years ago, it dawned on me that, because of geometry, it is completely unnecessary to have a hexagonal shape - and something of a disadvantage if you're building bellows for an Aeola or Edeophone! All you really need is a cylinder of the correct diameter. (I now have a fine collection of aluminium tubes, plastic drainage pipes and even cardboard postal tubes!)

Chris Ghent Posted November 17, 2014 Share Posted November 17, 2014 I find facets handy when gluing gussets. Link to comment Share on other sites More sharing options...
Mike Pierceall Posted November 17, 2014 Author Share Posted November 17, 2014 You're right, of course. The hexagon is based on a circle. Cutting a hex on a table saw was pretty easy for me, though, and I can make it to suit. Mike Link to comment Share on other sites More sharing options...
Mike Pierceall Posted November 17, 2014 Author Share Posted November 17, 2014 David, I'm intrigued. How do you suspend the tube for rotating the bellows from one side to the next? Some sort of hanger arrangement? My form sits in a cradle and pivots on dowels, for instance. Mike Link to comment Share on other sites More sharing options...
david robertson Posted November 17, 2014 Share Posted November 17, 2014 My tubes are suspended in a cradle just like yours. I glue a square bit of MDF with the corners rounded off into each end of the tube, drill a hole at the centre of each end, and stick a length of dowel through.
