The Bucking Magnet Motor

I've been looking for a way to speed up my process.  Every time I lock, or unlock a table clamp I have to pick up a wrench, and put it back down.  The more steps in a process, the more time you spend adjusting the work piece and not cutting the work piece.  So to try and make the process a little more efficient I replaced the flange nuts on the table clamps with wing nuts.  I'm going to cut the next segment this way and see if I can get away with using the wing nuts.  Using the flange nuts allows me to put a lot more torque on the clamp, thus more clamping power, and I want to see if the hand tightened wing nut can clamp sufficiently to do these cuts.  If they can, then I can speed up the process a little by not having to use the wrench to clamp and unclamp the table clamps...

Just another one of my wing nut ideas...

Well, there are lever clamps, and cam action clamps that I could have used.  But I bought the Adapta-Clamps for several reasons.  First they are designed to be used in the table slots, a big plus, and the lever clamps are not.  Second, they are forged, very heavy duty, and when combined with the T-Slot Nuts and hardened studs can provide an immense amount of clamping force.  The lever clamps are limited to the hand force on the lever, the Adapta-Clamps can be torqued with a wrench if need be.  But they seem to do good with the wing nuts.  I could also play with the wing nuts to get more torque by getting wing nuts with larger wings.  I have seen them up to 4.5 inches outside diameter.

If you look at the whole clamp, here...

I could replace the foot on the table with one of those Gibraltar Cam Levers.  Each of the clamps feet has a pin with a couple of spring clips to retain the pin.  I need to measure the table clamp to see if the lever will fit, and if it does that would be a sweet solution.  Then the wing nut is the tension adjuster like on a vice-lock pliers, and the cam lever locks and unlocks the clamp, and I can retain my forged clamp body and hardened hardware.  Looks like those cam levers are also hardened, judging by the price...  $25 each...

Thanks for the ideas...

I have often thought of using magnetic bearings.  What I had imagined was single form magnets that were a cones on the shaft and an inverse cones for the seat.  The seat part has a hole in it so the shaft can come through the seat.  Then there is a yoke which holds the seats.  A tensioner clamps the seats together and the shaft/cones are suspended between the seats.  The harder you clamp the seats together, the more slippery the magnetic bearing becomes, well, until you crash the magnets into each other.

The problem with magnetic bearings is these forms don't exist yet.  You would have to build a compound structure with many magnets, as you have, or pay the bux to have custom magnets built, not cheap.  When you are dealing with fringe technologies, and tenuous energies, efficiency becomes very important.  Magnetic bearings might make something possible now, that was just not possible before.  Imagine what Tesla could do with Neodymium magnets.  LOL!  We would all have spacecraft now!

This one fits perfect.  The pin is 5/16", the width is 7/8", the cam fits the casting clearance...  Rox!

Excellente!
