Rebuilt my scissor drive projector lift, as it just wasn't working. The new
version rides on ball-bearing drawer rails, which you can see in the pics. I
also have four "down" limit switches in parallel -- all four corners must be
down before the motor circuit is interrupted.

One final thing I'm proud of is the attachment o fthe cover, using the
perforated drywall corner bead. Adjusting the four springs allows for
precise positioning of the cover so that it snugs up into the ceiling.

Lift and screen are on an X10 appliance module which lowers and raises them.

I'll draw up some good quality instructions and close-up photos, a few
people emailed me and said they'd like to try to duplicate it.
