I see you bolted it to the floor. I was wondering how you were going to stabilize it. Great job.My homemade vise pedestal. https://picasaweb.google.com/110106108324823291002/VisePedestal02#
Thanks murph. I guess it will take a while for anyone to post anything else, but just to generate some interest in this thread, I will show this 12 volt electro magnet I made about 20 years ago to magnaflux engine heads for cracks. I got the laminated steel plates at a salvage yard. I think they were from a microwave oven transformer. I got the insulated wire from a motor rewind shop, along with some useful information on how to make it. I had to make a special tool to turn the laminate so I could wind the wire on evenly and not harm the wire's insulation (it's like a coating of varnish or paint). After I finished it, I took it back to the motor shop and they dipped it in that insulation for protection.
The magnet is so strong that 2 people cannot pull it off a sheet of steel. In the photos, I put a drink can for size comparison. That loop on top is just a rope handle to carry it.

To use it, sprinkle some iron filings on the area you suspect as cracked; then set the magnet on the surface and turn it on. The filings will move to show where the crack is.
Nice. Not sure if you are aware or not but when you check for cracks you need to check twice. The second time the magnet should be 90 degrees to how you had it set the first time.
Magnetic particle testing can only detect cracks going perpendicular to the poles of the magnetic.
made a horizontal shaper to make panel cabinet doors, it holds three shaper cutters and does the milling on the stiles and rails and panels,
one can mill out a door in about 2 to 3 Min's, if all parts are cut,
I think the best thing about it is relative safe one would all most have to try to get one hand or fingers in it, and a standard shaper is not that safe,
