Hi Folks, thanks for making this forum.
There's loads of great advice here. 

I've been making
~
60 cm diam rings by bending 5mm carbon rod , setting the ends inside a cuff and sewing these inside a dacron sleeve.
This puts the carbon rod under a lot of initial stress. So much that vinylester rods break randomly in the night. I should use epoxy.
From here they are compressed even more by 6 lines on a tensile torque transmission system. 
This is a very weird project making a flying wind turbine... https://windswept-and-interesting.co.uk

I'd love any suggestions or advice on how to make these rings better. ..I can't afford a bike wheel for every ring in a stack
Is there anywhere which makes a set pultruded coil which I could cut and set as a ring?
Is there anyone makes a prepreg packing or sealing gasket I could wrap around a large cylinder?
Should I just make corner blocks and use straight rods?

Thanks in advance
