I figure the cost of any change to the garage ceiling would have to include modifying the rafters. That is just not cost effective. As cool as it would be I am too cheap.
A dormer type of extension above the single bay which is where the workbench area is would still be expensive. I think a small scissors lift that tucks into the floor would be the best fit for my needs.

These folks are just a few miles up the road from me. They will build a lift to fit me needs. I friend of mine works there.
