Forgot to mention that in using one large weight **I don't have to have counter weight shaft ALL the way out **. About 3/4.
All the weight is concentrated in one spot closer to the RA axis instead of being spread along the shaft.4 on top of eack other.
what he is saying is correct that the momentum and torque required will be greater with the greater distance for the center of gravity.
I found that using the original multipull weights stacked along the shaft i required more weight and the shaft all the way out to balance my Newtonian.
The other thing to remember is the EQ6 shaft is not as large as say a Losmandy.
I have seen and used four weights on the EQ6 shaft and it has a definate bend to it and wobble when slewed and stopped.That's why I used just one heavy one and the shorter shaft.
You could make the shaft larger but where it goes inside the housing will still be the original size.
I have seen this done else where on the web a shaft made to just slide over the original and was held in place with grub screws.The original was only out about 2" out and this was what fitted inside the larger shaft.
I think for the weight handling of the mount the counter weight shaft could have been about 50% -100% bigger in diameter.
I just like to have things over enginered rather than be under and wobbly.
A wobbly EQ mount is useless for any thing except low power work.
Not sure just how many weights you will require in your set up but I know Tony has a C11 with a 4.5kg guide scope on top and uses the four counter weights.
As your tube is smaller in diameter but your guide scope is heavier I could only make a guess .If you mount it side by side it will have to be less thou.
You could use that formular but another thing to be aware of is the OTA sits a fair way from the RA axis on the EQ6.
From the RA axis center to the dove tail mount is 200mm (A) alone , then you have the diameter of the OTA and then a guide scope and brackets ontop of that.
