The video is 25x actual speed, so the actual winding process took maybe about 20 minutes. However it took a half day of messing around to set up the jig, get it to work and clean up the mess afterwards.

Id suggest FR4 or G-10 for the primary supports. We have had it waterjet cut several times now with good results. even 1/8" thick FR4 is pretty tough stuff, id stick with less than 1/4" thick for waterjet "curf" (it leaves a non-square edge). Could also be cut out on a PCB mill if you know someone that has one.

Well, that's what machining is all about. 99% set-up and jig making, and 1% actual machining! :)

I decided on 1/2" Tufnol for the primary supports. 1/2" so I could drill and tap decent sized holes into the edge of it, and Tufnol because it was cheaper than G10. I don't even know where to get a G10 type material in that thickness, we lack a UK equivalent of McMaster Carr.
Waterjet cutting was a complete failure, but I managed to get someone else to make the parts on a CNC mill.
