Default Tension Springs

Has anyone modified their Dobsonian with something similar to the Orion
Correct Tension system? I have a Celestron Starhopper 11" and need to come
up with some kind of tension adjustments as balance while switching
eyepieces is an issue. What type of springs did you use and where did you
find them. How did you attach them to the scope? Any additional info or
pictures you could provide will be appreciated. Thanks.
John

Guess not.

If you go to a full service auto parts store like Napa they often have a
collection of springs. Someone with a 10 GS DOB could measure the coil
diameter, wire diameter and length for you and you could duplicate it most
likely.

I could do that if I were at home.. :-(
