Book on Analog Prototyping techniques

You can even use one of these to cut large pieces, in a pinch:

It's cheap, and probably won't last long, but for very occasional use when you don't have a sheet metal shear it's usable. I don't know how it would do for small rectangles. Smallest I've done is ~ 1/2" x 1 1/2" No sharp edges - yet.

The ways are completely covered on my mill by 'accordion' protectors that cover sliding sheet way covers. Dust wipes right up. Not an issue.

Times four, times the number of copperclad snippets you need ...

Embarrassing.

I wasn't the only one that happened to :-)

It's one of the prices to pay when part of your job is fixing EMI issues. Another one was a panel that didn't come off. Well, put foot against system, gave it a good hard pull while letting off one of those Japanese wrestler yells, panel let go ... *CRUNCH* ... went through drywall with my shoulder. The guys didn't believe me but it didn't even hurt.

Hey, that sounds like a great DIY type project. Hmmm, i might use a dentists drill with diamond burrs instead, lighter and more maneuverable.

The

Verdamnt cookies required. Is it worth it?

Nah. It's just the Milescraft pantograph router adapter as rebadged by Sears.

Check!

Both copper and epoxy-glass will clog diamond burrs. A good toothed steel or carbide cutter works best in FR4.

And you can grind your own engraving bits too.

--Winston

I turn them on and off by hand. You can also set it so that the cookies are nuked after some time. And watch them thar Adobe flash cookies. They hide much deeper in your PC, most people do not know about those.

Isn't that what John was looking for? If you mount a Dremel holder, of course, but that can't be rocket science.

Think about a small gadget that could clamp onto almost any size or shape of PCB. It would have 3 or 4 or 5 degrees-of-motion actuators, and a tiny illuminated camera. It could just peep around, or it could carry a really tiny GHz fet probe, or a small cutter. You'd fly it like a flight simulator.

John

Let's ask. :)

Hey John, would the Milescraft tool do what you need?

Personally, I would imagine the scaling capability would be insufficient. I dunno, though.

Milescraft choices are 1:2.5, 1:2 and 1:1.6 scaling.

This one:

can be set up for

1:4, 1:3 and 1:2 scaling.

I think you're talking about a flying probe tester:

I lust in my heart after this one:

--Winston

You'll probably need something like an Isel gantry table. I remember them from Germany but no idea where to buy them in the US. Then you'd have a personal "drone in a tea cup", could fly dive-bombing attacks against a rogue SOT23 target and stuff like that :-)

Be a little smarter when you cut the pieces. ;-)

Embarrassing.

A whole company full of klutzes.

More than one person did that? After you got the panel off, did you put it back on so someone else could have the pleasure too? ;-)

T'is why I prefer buying that stuff. Time is money, and sometimes there ain't enough time.

No, actually the leader of the pack in their market. Very smart folks.

I was tempted, but no :-)

This was about potentially getting hurt.

Yeah, CMM-gantry. As Mitutoyo, Starrett etc. have. Not very convenient for a 3rd floor walk-up though- I think they typically weigh > 1000lb.
