I asked Composite Components , Bibra Lake, Perth for a quote to make my 314mm OD , 1.7mm thick CF tube , they estimate about $1000. Scrub getting the tube made by them .
Will likely source my unilateral 3K CF cloth, and plain or 2x2 twill weave 3K CF cloth and 2 part epoxy , make my own mandrel and have a crack at making my own CF tube.
In the meantime while I'm sourcing my raw materials , I've queried Vixen Japan re how well the New Atlux servos will cope with my 7.25 kg.m RA tangent arms eithe side of the RA pivot point (assuming I stick with my heavy OTA tube and buy 10.5kg of extra counterweights).
