Lead screw alternative?

I have been thinking about where I could get cheap leadscrews to build a cnc machine at a reasonable price. Today I saw a picture of a car jack, the scissor type jacks you can get as standard equipment in every reasonably priced car.

It dawned on me that the threaded rod used in the jack may might be used as a lead screw...

Anyone want to give it a try?
