Friction wheel, dome drive, gets chained to the desk!

Recommended Posts

My 4" [counterbalanced] friction wheel drive has worked fine on the underside of my dome's base ring.
The problem was trotting off to the other side of the dome to turn the crank at intervals.
This usually involved ducking under the large telescopes. Resulting in repeated injuries to my few remaining brain cells. :blush:
So I resolved to bring the drive crank within easy reach of my computer desk on the north side of the pier. [Lazy git!] :biggrin:

Here's the first mock-up involving the original counterbalanced friction roller with an added chain drive:
I just need to provide a solid support plate for the lower crank and chop the upper crank off at the boss for tidiness.
