Stepless Size

After thinking about complex and expensive way's of adjusting, I came to this! Simple, cheap, reliable, producable. I didn't had much time, I had to make it in only 2 hours, but I think the idea is clear. By turning the handle you can change the hight of the table via a simple gearbox in stepless motion. Adjusting is easy and light to carry out. Making detailed drawings is no problem at all, this simple CAD is just because of a lack of time. When you like it I can make the whole set of drawings and figure the gearing out. Stepless adjustable from 650 to 1050 with one handle! I geuss it is as simple as it can get. It should meet all the other requirements!
