Here are my drawings for "the Henri 3 Renaissance Hurdy Gurdy". I have modelled it on an existing instrument from Paris circa 1750. The main deviation from the original is that it can play a chromatic 2 octaves, has adjustable bridges and string lifting mechanisms. I have also changed the internal frame to use smaller wood stock. The original has solid end blocks that needed large wood stock to cut them from. There are 10 x A1 size (841mm x 594mm) sheets to this plan.I have written up the making of the Henri 3 Renaissance hurdy gurdy in a pdf booklet. This booklet combined with my plans "blueprints" will allow the construction of a period looking, modern playing hurdy gurdy.
Here is a photo of the finished "Henri 3" taken in July 2013. I'm working on the inbuilt preamp at the moment. I'll post the results as soon as I have the final circuitry up and running.
