Fancy you should say some engineer might have the math
it so has it that im currently studying engineering
I know about the leaver arm moment. It shouldnt put more stress on the motors as the weight is balanced out, and as long as the axial and shear strain/stress though the counter weight bar is strong enough there shouldn't be any issue with the whole setup. the math for working out moments and forces is just a case of Static mechanics as simple as pythagoras's therom. and it cant be that damm expensive to get a rod made up...
I think those 303 rings depending on the deminsions and how they specify will be for a bigger scope unless they are talking about radius to the Outer size of the OTA.
The only concern that i would have if anything would be if it would foul on the tripod or in that case the permanant peir that i will be constructing soon enough.
So at the moment you guys are reccomending
Losmundy conversion for affixing the tube
standard tube rings
extension bar or weights.
Though i think i might be going and talking to my bro inlaw, he used to be a fitter and turner and has contacts in the industry, might have to get something whipped up for a carton + materials.
