The Bucking Magnet Motor

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...

Got some more metal shredding time in the shop today...

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...
