Do you still use that D-sized plotter? :-)

That cat looks awfully dead in the 2nd photo, lying on top of the computer.

have!?

I like your drill press-cum-mill...

Bingo!

We downsized about a year ago, and since I'm not doing much hardware
production any more, it's perfect for development.

ANSI A to E size, actually, but generally no.

Three; Monty, Missy, and Josie.

Monty was the dead-pretend guy on the Windows box, Missy was asleep on
the chair, and Josie refuses to pose...

Thanks. :-)

I worry a little about side-loading the bearings in the quill but, so

Being a Spice guy, I wouldn't have thought you did much bread boarding.

If anyone knows a good source for those double sided perf boards (power
planes top/bottom and isolated holes, like Jim's pic, over the entire
board), anti up. Those seem to be hard to find at a good price. perfect
for wirewraping.

Not for chip designs... for my "G-jobs"... I tinker a lot with
home-brew gadgets, like aircraft noise trackers, school bus
annunciators, light controls via the street light sensor, etc ;-)

I laid that out myself while I was at GenRad, to ease bread-boarding
of analog I/C's from so-called "kit parts". I may still have the
original films around here somewhere (I save everything :-)

I'm just about out of scraps from that system (after 33 years :-)...
they were one-foot-square to start!

So I'm considering making a six-socket version for my G-job needs...
maybe run it thru one of those cheapy PCB houses (it's only
2-layers/sided)... maybe add some surface mount type pads.

For fairly high-speed (~100MHz) prototypes which need double-sided
copper, I like to use Vector's 169P44C2 cut down as needed, their T44
terminals to carry parts on one side and wiring on the other, and a 1/8"
drill to _judiciously_ remove the copper from around the holes where the
terminals need to be pressed in and connect to neither the power nor the
ground plane.

I've used their pad-cutting tool and found it to be absolutely worthless
after a couple of cuts, so I now use a vanilla 1/8" drill bit, in a
drill press, with the depth of cut set to just barely remove a 1/8"
diameter disk of copper around the isolated hole.

I've got some photos, somewhere, which illustrate the concept and, if
you're interested, I'll go find them and post them.

You might try lip and spur type drill bits, used carefully with a drill
press it can cut nice copper donuts out of the copper cladding.
They are somewhat related to Forstner bits.

This web page claims they're used by stained glass and lapidary hobbyists as
well, and still available with some looking:

Somewhere in my junk box I have one that cuts the donut AND drills a
hole for leaded components.

Yes those are the ones I was referring to.
I used to have a small wooden box with several in. You could create a
circular pad with .75mm hole in the centre.

The actual drill was secured by pressure from the chuck on the
tri-fluted shaft.

The diamond pad cutter requires a drill stand and a solid hold on the
board.
