Man, that's a big countersink.  I'll need to change the spindle speed first. 
Its at 990 RPM now, for the 0.125" end mill.  The 7/8" countersink is probably
a little larger than what this drill press is rated for in aluminum.  So, I'm gonna
take it down to minimum RPM, 250...

Then I get the table adjusted, and locked.  Adjust the table clamps on the plate, and clamp them.
Line up the hole to be countersunk, and engage the Z Axis (turn on the motor and start cutting)...

Totally sweet...  Nuthin' like that other table (Bitmore).  Rock solid, just as solid as when I use the
little mills.  Big cuts were scary with the Bitmore table.  The Palmgren does big cuts so much better...

Got a shot in there of the countersunk hole...

Then also a shot of the new UABMM2 plate marked up...

I finished off the adapter plate and got that installed.
That was a workout.  Fitting that 63 pound table.
Of course it didn't go the first time.  Gonna need the
big breakfast today...

Also got the new motor plate ready for spotting...

OK, there, I have the square cuts done...
Now for the curvvy cuts...

Nice Curves...

Not being able to use the rotary table for a couple of reasons, I has to use
some scrapyard ingenuity to make some nice curves.  The T-Slot nuts are
made so the threads stop at the back of the nut.  This prevents someone from
torquing a screw into the slot base and making a dent.  But, in this case, I need
a fixed point to be an axis for my circular cuts.  So, I took an 3/8 inch bolt,
sawed off the head, and then ground the end of the bolt to be an anchor point
for my circle.  The ground end of the bolt extends through the T-Slot nut and
can be jammed into the table.  This creates a hard axis on the table to be the
center of the circle.  Then I used a flat washer, a flange nut, and a jam nut
to create a locked tension on the plate in process.  Then the Table Clamps lock
the Plate down for cutting.

I created a BASIC subroutine to exemplify my process...

Start Process:
05 Process=Work
10 lock table clamps
20 engage Z-Axis (cut hole)
30 unlock table clamps
40 if Plate=Done then goto 70 else goto 50
50 Rotate plate 2 degrees
60 goto 10
70 Process=MillerTime
End Process

The Palmgren Table, and the new Clamps are like an Order of Magnitude
better than the Bitmore Table.  Excellent parts are made by excellent tools...

looks great so far.

been watching for some activity on this thread for a while now.

are you going to hard mount the magnets or make them moveable?

A video of a CNC machine doing this would be cool...
But, I'm doing manual control, its pretty boring...
LOL!  Get it?  Boring...  ROFL!  ...Uulgh...

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.

Economy Adapta-Clamps are here...

If you look at the whole clamp, here...
http://www.overunity.com/index.php?action=dlattach;topic=9656.0;attach=51534;image

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!
