Does anyone know where I can find a simi cheap magnetic chuck. I am going to devise a rail system for it and put it in a mill with a horozonal flat grinding wheel, so it can act like a surface grinder. I can't seem to find any though.

Thanks,
Jimmy
 
Harbor Freight usually has them for around $100.00 bucks. The Harbor Freight Surface Grinder can be had for under $1000.00 and works great when tuned properly.
 
Ok I am looking at the one from harbor freight. However, it dosn't say how big it is. If its like 5x10 or say 5x12 it would be perfect.
 
I had a Harbor Freight mag chuck 10 years ago and I don't know if they've improved them, but back then it was about $100 and it was pretty weak. You shouldn't be able to pull the piece off with your hand, for instance. I returned it (which is the nice thing about HF).

You can get a good used Brown & Sharpe or other American brand in that price range. They're often 6 x 12, 14 or 18.
I bought two American-made 6X18 mag chucks on ebay from a total of about $300 for my 36-inch belt/surface grinder not too long ago.

Damn thats good to know. I'll start searching Ebay. (6x18 would be great. :))

Does anyone have any more reviews on the harbor freight chucks? They have a HF near my house so I guess I could go out there and test one.
 
Some have told me to ask about the fine line ones. Most have the larger loops but the small ones are available and hold better for small work.

This is true, but strangely, the old U.S. made 'larger-loop' versions hold just fine--unlike the 'larger-loop' imports.
