Is there a cure for a wobbly drill press? On now on my 3rd eOrbo replication attempt! The drilled holes are lopsided, lol.

BTW, Happy New Year!

Paul,

Drills don't produce perfectly round holes. Worst case result is if there is some wobble in the machine or the piece, you don't drill pilot holes, or your feed rate or drill speed is wrong for the material and bit.

You can solve most elliptical hole problems by drilling pilot holes and making sure everything is secure.

@k4zep,

I use three Toroids (the one that is on power cables) with the size as in the attached drawing.
I threaded two of them with 4 wires in parallel 0,2 mm enameled copper wire. Did put as many
turns as I could on the cores, approx. 90 turns. I then epoxied the two toroids to the third
ferrite core. Did use two plastic rings to keep the generator coil in place. The generator coil
is wound approx. 200 turns with 1 mm enameled copper wire. The mostfet switch is
the Rosmary Anslie switch found in another thread in this forum. I have three pot-meters
to adjust frequency, duty cycle and mosfet gate trigger resistance.

Groundloop.

Don't know who makes your press,but it doesn't really matter its either a morse taper or threaded
Drop the table down  open the jaws all the way [oil] tap up on the chuck and tighten the screw inside to make sure its all the way seated/tight
Chet
PS run the jaws ALL the way open and closed a few times after oiling
check for damaged jaw [chucks are cheap to replace ]

@Groundloop. I suggested a rotor for the Stoern Orbo made from Flynn parallel path iron bars, coils and magnets sandwiched to the outside, that deliver four times the magnet strength to one side of the array, and zero to the other, when a small charge is applied to the connected coils. The polarization remains after the charge is removed. It occurred to me that rapid axial flux switching from a DPDT charge reversal in the Flynn array might couple with the Stoern cancelling toroid wraps to create a more powerfull solid state generator.

Members on this forum,

My solid state Orbo generator is completed.

First test:

Connected power to oscillator, adjusted oscillator, no magnets on the coils, output was zero volt.
Attached N35 Neo magnets (crappy magnets) and the output was 180 Volt AC no load voltage.

Will be back soon with more testing.

I'm fascinated and enthralled.  Good job, thank you, and I look forward to hearing of further results!
