i had same problem - look well at these images - not costly
strangely depends on whose etelon - coronado meade or lunt -
the external front etelon by meade small tuning ring is very free wheeling to the touch for tuning
BUT one of the club members has a lunt - very !! stiff not free wheeling.
mine in a coronado ... so i modified the images a bit - still need uprights milled & attached to tube directly in line !! with hole in each to accept the long tuning rod then the rotating rod freely rotates - at the tuning ring another disk is made & i used soft camping foam to encircle the disk that is slipped onto the end of the long tuning rod - the soft foam applies NO real pressure to the tuning wheel just old fashioned friction ! to rotate the tuning wheel.
if you know someone with a workshop the 2 right angled uprights 7 the front disk with a hole slides onto end of rod with a capture nut.
i take down this system each time i use the solar system - at the eyepiece end the rod needs onthing just your fingers rotating the rod
the front disk is smaller than the diameter required to come in contact with the etelon ring with the foam attached around the disk - must ends of foam must not overlap - just touch use a glue called goop to hold the ends together as a continuous wheel.
- easier than it sounds - study the 2 images on the site - must be willing to drill 2 holes in tube to accept the uprights directly in line with each other - can modify the holes if no in direct line - make second set of holes in tube if first set not in line the duct tape the first set of holes.
VOILA - IT WORKS
STAY SAFE GUYS
