Sewing machine electric lift

[Tuomas]

I have been thinking this same idea sometimes.
I planned to use "douple scissor jack" -system.. Just nice casing around it and some bearings to support moving stand, was my latest plan.

Wife decided that she doesn't need that kind of thingy, so never build it...
Of course that would be nice feature to have on the workshop too, to keep heavier tools away from the table when not in use?
