Carving tool for pcb's

As snipped, I get better control with a carbide dental burr than a grinding disk. The burr doesn't gum up with copper.

Show us some of yours.

I've considered something like that, but it looks like a big deal, and I also make Dremel mods to stuff on my bench, after it's all hooked up to test equipment. I usually remember to cut power off before dremeling or soldering. I've really got pretty good at hand cutting FR4.

The gold plated FR4 is a nice touch. It solders beautifully and stays shiny... no corroded fingerprints a few weeks later.

Just clean the copper and apply a clear acrylic spray. It dries instantly, you can solder through it, and eliminates corrosion and fingerprints.

A proper pantograph thing could do a wonderful job. For one thing, it does a 2:1 size reduction to reduce your hand jitters (even trace an enlarged print), and for another, you could run the stylus along a straightedge to get perfect cuts. Stop at any point to rotate the straightedge 90 degrees and keep following it, and you'd have perfectly straight rectangular cuts.

Seems like a nice idea, I wonder if there's a commercial Dremel pantograph available anywhere.

Simple in concept, but not to get the required stiffness. There's a workable plan on Instructables however. Non-enlarging pantographs are even harder; even more ways to get it wrong.

On the other hand, I've been contemplating how to build a poor-mans pantograph for carving arch-top guitars (short of full CNC) with a serious router on board. The Dremel for PCB seems a good bit easier.

I haven't actually used one but these look fairly decent.

Yeah, naah, not even close. Might handle 2 dimensions with a 2mm cutter and very slow speeds but it has no bracing to keep the height correct. As soon as the tool bites the whole thing would flex by multiple millimeters and squirrel all over the place.
