Well I am between 5 and 9 years late to this post.
I have just picked up a Warco 220 for pretty much silly money. It has come from a school and appears to have had very little use, which is always nice 
The downside is that it did not come with any tooling, or screwcutting gears. I knew this when I bought it.
The second downside is that (probably for reasons of safety) the school un-installed the lead-screw drive mechanism. It is missing the gear which meshes with the spindle splines, the one with the 3 small pulleys for the 'friction disc' to engage in.
Does anyone still have one of these lathes, and if so, would it be possible to have the dimensions and tooth count of this gear so I can make up a new one?.
Many thanks
James
