Electromagnetic Drill Press Vise!

I've made a mag chuck for my milling machine, and a Magnabend starting from basic principles. You will find that thinner wire for the windings and a greater number of turns will be more effective and provide a longer duty cycle. I suggest you measure the current draw because I very much doubt you'll need more than 10 amps at about 50 or 60 volts to get a very effective magnetic flux.
My Magnabend will pull about 10 tonnes. It's 750mm long and will bend a piece of steel 100mm wide and 16mm thick whilst being supported on 5mm blocks at either end. The steel springs back when the power is off of course.

Why dont you offer it to this website would be intereested in the design?
