View Full Version : Double sided tape

03-05-2007, 12:48 AM
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,

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?

03-07-2007, 02:38 AM
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:argue: 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.

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/industry/products/doubl2350/doubl2386/78978.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

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 :)

I contacted the ebay seller that I mentioned in the first post.

They are going to send me a sample roll for free :p

03-08-2007, 08:12 AM
Yes booger it is...On the nose. For sure english is my only forien language I took in school. The hardest 4 years of my life was the 12th grade. The last two years they let me co-op as the bus driver. Don't read what I type just read what I mean man.

03-08-2007, 11:43 AM
Did you mean "foreign" (chair) BTW: Please stop discriminating the booger eaters of the world. They can't help they where born that way. Lets have a group hug(group) Can't we all just get along.

03-09-2007, 10:22 PM
It'd be impossible to have a group hug with a group of booger eaters....... They'd be too busy diggin’ with their right hands.

But just as a note, I tried the carpet tape idea as well as a few others. But none could beat good ol' duct tape. That is, for what we were doing. In fact, we even began to have a problem peeling off the parts because they would bend (2inch tags). In that case, I just turned on the coolant for a little help.

As a side note to the guy who made the remark about using the vise top.... I had a #1 center drill lose position into the vise top (decimal error). The spindle stopped dead in its tracks... rotation and Z-movement. To my surprise the center drill minus the very very tip survived.

How did you use duct tape?

03-10-2007, 11:12 AM
Double sided duct tape. Very powerful stuff. The DUCT company (has the little duck on the packaging) makes it and I believe it was purchased at Lowes. Ours came in a white roll and had a very thin piece of non sticking material on one side.

We used the top of the Kurt vice, so it made it super easy. For the tags I set up a program to run an array of around a dozen. I set the offset as the corner of the vice for 0,0,0 (so that I could use the offset function to locate the top of the parts later). I would take the edge of the tape and stick a little over the left side and lay it smoothly across to the edge of the right side. I would then use a utility knife to trim the tape off of the roll and the left side's excess. When doing this I would trim the covering a little to make it easier to pull off the protective covering of the next strip where it would be excess on the left side. Then lay the parts on it.

Added notes: It is important that if you have to slit the covering to remove the covering, it is easy to ruin the level of the tape when slicing in. If you don't do it just right you will mar the tape’s surface and throw off the whole part. Also, with this stuff, a little goes a LONNNNNNNNNNNGGGGGG way, the longer you let it sit with pressure the harder it will stick.

Good luck!!!

I use the carpet tape from Home Depot. I think it's about 4" wide or so and is about $8 a roll. THey have both Heavy and standard. I've used both get good hold down and easy to feel off. I've also used the double stick tape from Brontapes, it's a lot more expensive so I made the switch

i have used double sided tape in the aerospace industry for machining upto 1" thick aluminum billets with a depth of cut upto 0.1" deep, just clean the table with alcohol and also the material, applie the tape to the table and lay down the billet of material. works fine. secect is to use plenty of collant so that the part does not overheat and come undone from double sided tape, also used loctite glue (black in colour cant mind the loctite code number think its 937 or 950) straight onto the table and bond the part to the table just machine profile and any thru pockets 0.005" shy of depth easy to break material arond profiles and thru pockets.

I am also a big user of double sided tape, but there is another trick that works as well; A fillet of hot glue built up around the workpiece between the piece and the table allows it to sit flat on the table, avoid any lateral motion with quite some tenacity, and still peel up quite cleanly and easily - especially to remove fragile workpieces that might not like being pulled up off of tape, or to add additional reinforcement against the tape allowing any "walking" of the piece. No sticky goo, either.

05-07-2007, 04:06 AM
I had thought about using hot melt glue for that, I milled some PCB's and didn't know how much tape to use at first so I covered the whole PCB blank with double sided tape, big mistake :) nearly snapped the board in half trying to get it off the machine haha, now I believe in moderation, a little goes a long way...

Might try the hot melt glue next time.

that normally my prefered hold down ,
works well

The 3m#77 does work good. I have had good experience with superglue as well.
Ya just have to soak it in acetone for a while to remove it, get the medium stuff from a model shop.
Also if you are after a good double sided tape that's very thin, go to Officeworks and get the 3M Scotch 410 19x32.9 double coated tape you wont go wrong.

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

I've bought some of this type of tape from Bunnings.

Made by Norton Pty Ltd, with a picture of a bear on it. It's just called "Double Sided Tape". The packaging says "Ideal for laying floor coverings.... 36mm x 4.5m"

I've used it to hold down some acrylic sheet. I used too much tape, and broke the acrylic trying to separate it mechanically.

Thanks, I'll check that out. :)
