double sided tape source?

The 2 sided carpet tape is awesome on clean surfaces, it might be hard to get a very thin piece unstuck without solvent.

It improves with age. for your use it will have to hold the "grindee" on a plate and sit for a while. After time it has surprising holding quality.

It has a sponge effect, so accuracy will always be a problem.

If the engraver _really_ screwed them and is not a relative , why not get them redone? - that question is a "do as I say, not do as I do" sort of thing.

Sometimes in a workplace you find snot on the wall of the toilet cubicles. You feel "What sort of twisted child would do this?"....the internet seems full of them. It's very sad

I haven't used it for machining yet, but this stuff is pretty handy:

I like hot-melt for stuff like this. Warm the steel plate you are attatching it to, heat the brass to quite warm with a blowtorch, and simply smear hot-melt onto it. Press onto the plate firmly.

Quite hard to dislodge. However, I have never tried this with a surface grinder, and don't know if enough heat would be generated to cause problems, or if flood coolant would be a problem.

Cleanup is easy, you simply warm the object, and wipe it off with paper towels.

double sided carpet tape. Its about .09 in thickness when peeled. And it can be a bitch to get the part off of it without bending a thin part. Try that 3M tape on a properly cleaned table..you may well be surprised at how well it holds.

That stuff will work if the parts are clean and flat. The carpet tape holds real well but it is hard to remove the parts from the chuck and the tape from the parts. Do you have a vacuum source? You could make a vacuum chuck easily and it would be faster than taping the parts. ERS

I've used double-sided carpet tape from the hardware store for light milling. In some cases, actually milling small slots right through flat stock. That worked fairly well so long as the workpiece didn't heat up enough to loosen the adhesive.

Might be a good idea to try it on a piece of scrap first.

I've had good luck using acetone to release the part from the tape.

I don't know about the thin tape. With something relatively thick like carpet tape, you may have enough room to "saw" it off using a wire garotte.

There's a whole bunch of different types of double sided tape, check McMaster et. al. for perspective.

There is double sided carpet tape, but if you really want it to stick, use the double sided foam stuff. Really tenacious and easy to use. Available at any store.

We used both double sided tape and spray on dry mount glue to machine foil gaskets for vacuum systems (.005 24 k gold for example - you've never seen such a carefully cleaned lathe as after that) when I was in grad school. Stuck them to a smooth faced billet, machined the gasket and then used a propane torch to melt the glue and the part fell off. Seems like the same technique would work with a surface grinder. That double faced Scotch tape is pretty wimpy by itself but when you get a few square inches down, it's suprisingly tough. In general, glues melt and flow as you heat them up, so a little judicious heating should release the part. Best thing to do is experiment and see what happens.

Go here:

I bought some double-sided carpet tape, stuck it to my mag chuck, used some blocking besides, worked just fine. The parts are now on their way back to the engraver. Thanks to all.

Check your local (or online) art supply stores. Also, some office supply stores carry it.

Carpet tape ?

Might have trouble keeping it flat with any tape.
