magnetic chuck/vice ?'s

[raddksn]

I have a magnetic chuck/vice for a surface grinder at work someone else took apart to test the coils. That guy is not around anymore I need to get this thing back together. It's made by LW Chuck Co. Toledo Ohio, i think in the 1940's. I'll get pic's when i get to work. It has 12 coils apparintly wired in 4 groups of 3 . Anyone have info or links to info thanks.

I thin I have the wiring figured out tested it with 12vdc worked ok some mag. force and no smoke. now i want to test with 110vdc can i make a rectifer good for 330 watts from radio shack parts? If this works we will buy a chuck control but thats $1200.00 just want to test on the cheep!

Radioshack should have some bridge rectifiers pretty cheap, it should be like a $2 part.
