Double sided tape

[Greolt]

In Australia the carpet layers I have asked know nothing about double sided tape.

Evidently it is something not used much in the carpet laying trade here.

So can someone who is familiar with using it as a hold down method in cnc vee carving etc, have a look at this ebay item number.

Tell me if you think this is the type of stuff you all seem readily able to obtain in the US.

Thanks, Greg

looks like the stuff ive used before ,if it"s approx. .005 " thick it is the same stuff ,
it works ok and doesn t throw out the parallelism as much as the thicker tape

Bron tapes http://www.brontapes.com/index.html supplies double sided tape, they call it "killer red", up to 60 inches wide. Sticks great and peels off easily without leaving any residue. It's kind of expensive but worth it. I just cost it into the quote.

Good luck,
Todd

You might also want to try a spray adhesive. 3M #77 is pretty good stuff. One can will coat 200 sq ft. At $16 a can its cost effective, if it can work for your project. If your really hogging out some material you can "frame" the part with some blocks to keep the material from shifting and the tape or spray to keep the material from lifting. Just an idea.

That sounds like a reasonable idea Todd.

Have you tried it? Is it easy to remove when finnished?

[todd71]

Yeah. I did it today with some .06 polystyrene. I used #77 to stick the sheet to a .250 sheet of mdf. Keeps the thin pieces from moving around. It leaves a film on the material. I use WD40 or rubbing alcohol to remove the residue. If this is a problem you can apply some tac paper, like what comes on a sheet of plastic. Its easy to peel off and leaves no residue. You can see on one of the pictures that the MDF is still stuck to the back. Even then it doesn't take much to get it off. Works great for what I'm doing. As for the double sided tape and "frame" I do that most of the time when cutting wood. Unless I can just screw it to the table. From time to time I screw a piece of MDF to the bottom side of the material. Then flip it over and shoot some screws throught the top side of the MDF. Thats if I dont want holes to be visible on the top side of the stock. My vacuum motor is so loud I cant stand to hear it all day. So I do these things to save my ears for the old lady Good luck

I got some from the carpet guys, all it has is Tenacious Tapes written on the inside of the roll, I think it was Carpet One that I went to, I will check that for you.

The stuff sticks like you know what to a blanket, I used it to stick blank PCB material to the router for milling, and now for sticking the same stuff to the cardboard carrier for direct printing to PCB, works well, though if you don't need too strong a hold, don't totally cover the contact area, use strips. The first PCB I milled I actually had to pry off the router with a screwdriver, it didn't snap but had to be close.

Cost me $25.00 bucks which I thought was a bit steep but it will last me a long time for what I need. It is very thin, doesn't affect the direct PCB printing process at all. Fairly easy to remove, so long as you do so quickly, harder to remove the longer it sits.

I just googled tenacious tapes, this link came up first, might help you get a distributor.

Greg,

The double-sided tape I use for holding workpieces, (and loads of other uses), is made by a company called Tesa, and is called
4970. It is 0.24 mm thick with an incredible acrylic adhesive.

Here is a link http://www.tesa.co.uk/professional/i...386/78978.html.

Tesa do a wide range of other double-sided tapes.

Tesa have bases all over the world including Sydney. The web address for your region is www.tesa-asia.com.

Best wishes

Martin

I use to do alot of small prototypes. The tape I liked the best and still use is 3M poster tape from walmart. It is made to remove, well for lack of a better terminology like, well, a bugger. Ok I said it, I know how to roll one. But I do flick em. Good God don't eat em. God only know where your nose has been. But seriously the 3M poster tape worked well and came off without a sticky residue. It is 2 sided and I would stick one side to the aluminum plate or a vise top, (side note to self the aluminum plate is the way to go unless you like signing your vise top). It is all fun and games till someone poke out an eye.

Erm , did you mean booger by any chance...lol. Would make your explanation clearer in my eyes at least. Funny how little typos can make large differences in meaning
