What kind of time frames? Is it something that you can make template
guides for? I'm not all that far away (up in Denison) and my PM1K has
plenty of idle time. I haven't got it CNC'd yet, but that is on the
project list too.

I'm retired and grown plumb lazy these days, Pete.
I don't do much of anything fast any more.
So no pressure on time frame.

What would a template need to be made from?

I doubt CNC would be all that handy in this case.
Only a couple dozen parts needed.

But, yes, I'd be real happy to get 'em cut out!

Unless it needs to withstand a number of passes, I expect regular 1/8"
masonite or similar would be fine. Probably get slightly charred, but
the cut speed is so fast I don't expect it would go up in flames. The
chart in the manual indicates that optimum cut speed for 10ga (3.4mm)
stainless at 60A is 159 IPM (4039 mm/min).

The shield on the plasma torch is 7/16" OD, and the kerf is probably
between 1/16"-3/32".

Perhaps not, but it's typically easier generate some G code than to
calculate and cut a template.

Always good to make progress on the projects...

Using plain old Google Groups, I get:

aux3(dot)doh(dot)4(at)snet(dot)net

Punctuation masked to protect the allegedly innocent.
