I have a project where I very simply need to raise and lower a flat board with a 50 lbs drill press 35-40 in. and have it stop at the same specific place every time going up and coming down. I've seen TV lift mechanisms and things such as that, but they cost $500 - $1,400. I need this project to cost very little. <$100 if possible. I have a scissor design that I will be made from wood that I already have, so all I need is a motor that can lift 50 lbs up and down, slowly, quietly, and only once or twice a week. But I know nothing about motors. Here are all the parameters that I can think of. 1.) It will be stationary, i.e. — not require a battery or ever need to be moved. 2.) It must move slowly. Lift the surface approx. 1 in per second. i.e. — around 30 seconds to raise the surface 30 in. or so. 3.) It must be as quiet as is reasonable. It doesn't have to be whisper quiet, but def. not power-drill loud. 4.) It must be as inexpensive as possible. I do not care about... 1.) Motor weight 2.) Dimensions 3.) Power consumption 4.) Heat production 5.) Longevity... it will be used very rarely so wear & tear is a non-issue really I very much appreciate any help you guys can give.
