BTW if I farmed this out to a local shop for plasma cutting it would
cost me $6 per disc. Cutting the same disc with a jeweler's saw costs
1 hour, 2 blades and a sore shoulder.

Greetings Michael,
Trepanning the steel would work well if you have a rigid setup and a
slow enough speed. Hole saws don't have much room for chip evacuation,
so you need to keep pulling the saw out of the hole to clear chips.

Set your saw and turn it on, lowering it to the work. Now you have a
scratch of the diameter of the saw.

Now take a drill motor and drill a hole in that scratch. This hole now
lets the chips fall through as the saw turns and cuts away the metal.

If you measure the radius..you can drill the chip hole and the pilot
hole at the same time and do this as many times as necessary for all the
holes you are making.

It helps tremendiously to save the saw, to make the cutting go faster
and so forth.

Perty ingenious.....

Now, iffin only yer politics could follow suit....

Still, ahm gonna move in with you, in a year or so....

Ill set up a tent for you in my empty lot next door. Just dont bother
the neighbors pit bulls. They tend to keep me awake and keep my dogs
running from window to window trying to see what the pits are barking
at.

As for my politics...shrug...Im not a leftwinger...and I own my own
place free and clear...and a few toys of this and that nature...and can
support my family. What else is there not to love?

such a man for their? president.. Blaming the prince of the

fools that made him their prince".
