That sounds interesting.. Got any drawings? (Or pics).

Hi DaOldMan, here you go, sorry for the delay (camera was at work).

The width is a perfect fit for a 2x4, sometimes the cabinet gods smile on their worshippers :)

Chains only need oil so they can flex.  If you're mounting the chain to a solid surface and using the sprocket to push against that, no oil necessary!  :cheers:

Another idea could be to use a rubber wheel on the end of the motor, then spring-load the motor/wheel contraption against the wooden monitor wheel.

Hey solderguy1, that looks neat.
What do you do? Mount an LCD to the base of it?

You are right crashwg.. I suppose a setup like that wouldnt need oil, except maybe a thin coat to keep the chain from rusting?
A rubber wheel on the motor might work..
I will give that some thought.

*Edited for spelling*

Yes, that's the plan.  The lcd has four threaded holes in the back, so I'm gonna mount a chunk of 1x6 to it, maybe with some washer stacks for standoffs.  Then another four bolts to mount the other side of the wood to the caster base.

I was also thinking of extending the board out in one direction for weight so the monitor will turn until it hits a hardstop.  That way the motor/cord only has to provide force in one direction, just slack in the other.
