Our club has been donated a 14" completed mirror. As yet we haven't figured out the focal length. We are thinking of using carbon fibre tubes with aluminum spuds at the ends for the truss system. Does anyone know of a Aussie supplier for carbon fibre tube up to 25 mm.
Nope, but I do in GodZone. I got mine for the 10" refurb from here http://www.carbon-tube.com/
If you need, I can assist (if they don't ship across the ditch)
For the 10" I used the 20mm with a 1.2mm wall thickness I think.
