*Shielding Tape*
:scowl: Apparently the edges on the copper tape are sharp enough to cut you! This is proven by my newly lacerated right hand pointing finger...It could have easily took 4-5 stitches which brings up my next point.........Praise CA glue!! :bassist:

+1 to the max.

That crap is like flexible razors. I was shielding a bass once and suddenly noticed that blood was pouring from one of my knuckles. Didn't even feel it.

Wanna play frisbee with a copper disc?

I throw first :)

:hiding:

Any pics?

Did you put CA on your bleeding finger???

Most people do not know that CA adhesives ("Super Glue"), were developed for suture-less surgery. CA is made from organic compounds that will eventually breakdown when exposed to natural body enzymes.

It was back in 1988 when I was trimming/scraping binding on a guitar with a new #11 X-Acto blade, and I slipped and cut the tipof my left index finger pretty bad. Remembering what I had read in (I think) an AMA Journal, I reached for the Super Glue. It burned like HELL, and I had to keep reapplying it, but I healed without a scar or stitches.

So...glue up, dudes!!!

:)

Ah yes but are you sure that it is the same compounds nowadays? Hope so. Someone whould find this out. Do they still use this suff for surgery or not?

Super Glue is definetly safe to use on cuts nowadays, I know dozens of people who use it, I haven't cut myself badly enough to need it since I was informed, but I plan to use it if I do

i stuck a razor in my knee (slipped while cutting something) and superglued it it shut with regular superglue. it worked pretty good since it was in a very hard place to bandage.

i feel your pain scott copper cuts make paper cuts look weak

Yep copper cuts suck, but people scare me when they use Ca on and open wound. I have a friend that does that and I'm surprised he's still alive. The thing that scares me is what if some liquid glue decides to travel to the hmmm let me think here, the HEART!
Yikes it's enough to scare me.
By the way the CA we use and CA medical staff use have to be quite different, after all I think they charge at least $500 to use it on you. :)

From Google:

"cyanacrylic acid (krazy glue, super glue) was in fact developed for use in Vietnam. It is often used in emergency rooms and is called Dermabond. Same difference, except it costs alot more to have it applied there. $1.09 at the hardware store or $300 at the ER. I keep a tube in my first aid kit.You're close, except it's not "cyanacrylic acid," it's "cyanoacrylic acid." :)"


Mike

oh man, interesting read. ive been putting superglue on my paper cuts (thanks mom) for a million years

CA isn't mean cyanoacrilate which came from cyanure (not sur about the spelling one more time!!) which is poison?

i feel your pain scott copper cuts make paper cuts look weak

Just remembered the Jackass TV show whenthis guys start tu cut themselves with paper between their hands and feet fingers!!! I was hiding my hands and feets just looking at that as if those guys would came off the tv and start to do that to me!!! :p

I had a much worse cut on my hand got cut with a utility knife that laying carpet. I glued it and its fine now. I think the thing to do is wash it good, disinfect it, and use glue that has not been opened before. I can't imagine germs living in the stuff anyways but I would not use a bottle if it had already been opened.

Did you put CA on your bleeding finger???

I had to apply pressure and stop the bleeding first. It was kinda tricky, because just when I thought I had it stopped enough it would bleed a little more and I had to start over. :rollno:

We use copper tape at work all the time for shielding things or bonding test equipment to the ground planes in the lab. I always warn people not to use their fingers to press or rub it down - use a screwdriver, pen, etc., because I really don't have time to be driving people to the emergency room.

I don't know that I'd be too keen on dumping industrial grade CA glue into an open wound, regardless of whether it was originally developed for medical applications. Krazy Glue probably isn't sterile, and it's not going to be held to the same sort of purity standards as a medical product. If I couldn't close the wound with normal basic first aid, I'd be heading for the ER. The only way I'd ever use industrial adhesives on a human would be in the event of a life threatening injury where it's the only way to get them to the hospital alive.

CA is inherently sterile, so there are no worries, and it is WAY too viscous to be snatched up by open capillaries to wind up elsewhere.

Medical-grade comes in guaranteed sterile bottles, and is, of course, way overpriced because of it's destination and end use. :rollno:

I wouldn't worry about using it. After 19 years of using it regularly, it hasn't killed me. I'm sure that the inhalation of CA curing fumes and the accelerator, plus the lacquer thinner, acetone, CFC solvents, xylene, solder fumes etc. have done me more harm over the years. :help:

"Super Glue" rocks, after working through high school and college a couple of times... as a night stocker in grocery stores, that stuff saved many trips to the ER, due to "Slasher Movie" rated cardboard cuts. I of course always made sure my tetanus shot was up to date.....

I just bought some shielding foil to do a shielding job on my Jazz 24. I will make sure I have some Super Glue handy.:)

I've never cut myself on copper tape before, but it's something I'll be looking out for now. I prefer shielding paint... much less hassle, and no risk of cutting yourself.

I wish my patients would glue their cuts instead of visting my ER in the middle of the night.


They're mostly drunk though:p

In 1998 the FDA approved 2-octyl cyanoacrylate for use in closing wounds and surgical incisions.

Most cyanoacrylate glues not designed specifically for medical use are formulated from methyl-2-cyanoacrylate, since it produces the strongest bond. Not only can such glues irritate the skin, during polymerization they can generate significant heat, to the point of causing skin burns.

Maybe ok in small amounts but CA also releases cyanoacetate and formaldehyde while curing in the skin.(Thats bad unless you are a goth.)

Band-Aid Liquid Bandage cost about $7

UGH

I forgot to order some copper shielding tape!

geez, I knew I forgot something when I ordered for the band ::rollno:

would a Lowes or a home-depot near me have an adequate version of shielding tape for use on Basses? Preferably one that doesn't lacerate ;) ? hahhahha

If you want to be sure, you can buy medical grade CA. Its called dermabond, and one place to get it is www.bmeshop.com. They also have other "verboten" medical supplies, like scalpels, needles, sutures, and surgical instruments.

+ 1 , I ve got a big patch of Superglue in my elbow, bike accident, lost a chunk of meat it was to wide to stitch so they filled it up with glue in the ER.

I thought all superglue was ok to use. I glued my lip together once, because I had a day off, and didn't want to ruin it by going to get stitches. It worked really well! There's a scar, but it's not very visible. I hope I didn't give myself future cancer or something!
Formaldehyde doesn't sound healthy!

It is used all the time in pro sports, mainly hockey.

lowsound

yeah I wear mechanics gloves when dealin with the stuff.

the first time I used it I had hundreds of small cuts on my hands.

The way I've heard it is that when the stuff is exposed to oxygen, an exothermic reaction occurs, which is what makes it cure. Apparently the med grade stuff cures at a lower temperature (more slowly?) that the consumer grade, and supposedly the consumer stuff could in theory burn you, doing more harm than good. This may be urban legend, maybe it only applied to early products, I dunno. Just what I've heard. That said, I've used the kind from the supermarket and it's never had any ill effects.

Hey -

If someone can drop me a PM with a clue where to buy copper tape for shielding, I'd appreciate it. Someone suggested auto parts stores - went to three of them and they all pointed me toward chrome tape. That ain't right.

Thanks!!

Our neighbor (a vet) turned us on to the superglue when I sliced my finger on a metal switchplate. Just make sure you refresh your supply every so often.

just to check in, recently copper-shielded my main gigging bass...I would like to say, thank you OP, for the warning...I was very careful :D

Chrome tape might work, not sure if it's made with conductive adhesive though (& if it isn't it'd be nigh on impossible to ensure complete screening). However...BassPartsResource (http://guitarpartsresource.com/bass_elec.htm) has Copper shielding tape in a couple of forms.

I picked up a roll of the stuff for small money from a shop on Ebay here in the UK - enough to screen at least three basses. Here's one on your side of the pond (http://cgi.ebay.co.uk/Copper-Shielding-Tape-1-X-5_W0QQitemZ130154014698QQihZ003QQcategoryZ47067QQr dZ1QQssPageNameZWD1VQQcmdZViewItem).

Wow, I've copper shielded 4-5 basses and have never had a single cut from the stuff.

Try www.newark.com, Newark part number 44F3261. This is the 3M stuff we use for RF shielding and bonding in the lab.

ditto, but it's still a pain in the butt to use. I prefer graphite paint.

I bought a roll of copper tape from Ebay to shield my jazz.

Oh and a huge +1 on the superglue! My mate had a bit of swarf fly out of his machine and slash his bottom lip. Went to casualty and they superglued it up for him. I slashed my hand open on a broken mug the morning of a gig two weeks ago. A little bit of superglue and a whole lot of stinging later the gig went swimmingly.

I found rolls of aluminum tape at home depot for about 3 bucks a roll. It was on the isle with all of the duct tape. I think I'm going to give it a try.

If the tape reads a relative 0 ohms then it should be fine. Check that before you start sticking it all over your cavity.

Bought my big roll of copper tape from StewMac. Bought small amounts from Warmoth and Carvin.

FWIW, StewMac also carries the conductive paint.

Just squeeze the cut closed together, and then put a few drops on. You shouldn't be putting the CA glue inside the cut, but using it to form a seal on the top of the cut. Then blood can start clotting underneath and heal up the cut. A few days later the glue will rub off or fall away as dead skin cells replenish themselves.

I was able to find copper foil at a stained glass supply shop.

took a friend to the ER with a cut. kinda bad. on the hand. doctor looks at it, takes out a tube of crazy glue, and goes to town. tells my friend to just go buy off-the-shelf crazy glue to put on it, and any other similar cuts. so yeah, it's the same stuff.

which is easier to use?

which is easier to use?
conductive paint is easier and cheaper if you're going to be shielding a lot of guitar/bass.

Foil you can solder to and you can buy in smaller quantities so it's cheaper if you're only shielding one guitar/bass.

Copper tape was super easy to work with
Just ot done shielding my MIM jazz bass and BTW no cuts at all :hyper:
