Ultramagnus--Could you explain the servo modified for continual rotation?

ok, well i have done this on small servos before but not the sorta size you will need, but i cant see that will be a problem

basically, servos only rotate so far before stopping, to modify them you need to stop the potentometer from being linked to the drive shaft, its usually a case of cutting off a small peice of plastic or metal

ultramagnus:
you know, it just occoured to me, couldnt you just attach a servo to the hinge on the "door"? would simplify things

KonkeyKong:
I'm lovin' it, you guys are giving me some killer ideas here.
Just to clarify, I already have the cab built.  The control panel is the right height for me as well as people who will be standing at it, (maybe not really tall people).  I can roll my chair right under and reach everything rather well.  I'll try to get some pics today.

KonkeyKong:
here are some pics of the side and underneath the monitor shelf to give you a little brain-fuel.  The cab is just sitting on the boards on the floor for protection, they aren't attached.  The blue stuff is masking tape to keep paint from clogging up my t-molding grooves.

While I was sitting out in the sun, on a rather steep incline I realized I might just have been sitting on the answer the whole time.  The fact that my wheelchair wasn't rolling backwards got me thinking "wheelchair motors lock in the off position" Plus they are compact, variable speed and high torque. I know a couple guys with a wheelchair shop that I just happen to be going to see next week to put new motors in my chair of all things.  Funny how things work sometimes, I'll keep ya posted, meanwhile I'm still looking for any ideas you might have.

I think this is the best idea in the thread. 

Here's a $50 12V winch

If you put that winch in the cabinet to pull the front up and back, I think that would be the ultimate solution.
