Supergluing your fingers together
Surprising I've never done it before . Thumb and second finger firmly glued
to either side of a connecctor. I tried methylated spirits first but no effect seemingly. Then dilute acetone as nail varnish remover. I was concerned about being too long on the skin so some cotton wool balls of acetone around both areas and a Q-tip soaked in acetone, with a rotating wedge-like motion, cautiously wedging skin from connector worked, but anyone elses experiences/advice for the next time? Anyone ever glued one hand to the other ? |

Anyone ever glued one hand to the other ? I glue large cuts together. From what I've heard/read Cyanoacrylate was developed as a substitute for stitching wounds together on the battlefield during the Vietnam war. Little wonder it bonds skin so thoroughly. It's also used in its medical counterpart for some surgeries. Back to gluing cuts. I was sharpening a large hunting knife and managed to cut the side of my right thumb to the bone. Cut was about 2.5cm and I could see bone and other structures underneath. Didn't look like I cut anything else and my thumb still worked ok so rather than getting it stitched I used a grade of cyano we use for guitar work. Got the bleeding stopped, wasn't much to begin with. Applied the glue and the cut was closed immediately. I put cloth tape around the joint so the thumb wouldn't flex as that was where the cut occurred. A week later the cut had healed well enough to remove the tape. Now I have a scar but it is a straight line. Be happy to upload a pic of it. -- Live Fast, Die Young and Leave a Pretty Corpse |

From what I've heard/read, cyanoacrylate was developed as a
substitute for stitching wounds together on the battlefield during the Vietnam war. It was actually developed by Kodak in 1942, and was originally used to splice film. http://en.wikipedia.org/wiki/Cyanoacrylate |

Or rather: patience and warm water as the most important ingredient should go first. One other thing to notice: superglue may be a marble in some cases, it has very poor resistance to water. Anyone ever glued one hand to the other ? We may be sloppy but not that stupid ;-) You may however drop by the nearest convent and ask 'Why?'. -- Kind regards, Gerard Bok |

Anyone ever glued one hand to the other ? They do make a specific solvent for CA; we keep a bottle on hand at the shop. I have no idea what's in it, but it works very well on skin and other things, too. We do a couple of assembly jobs involving CA and by the time you've worked with it for a few hours at a time, you're pretty much guaranteed to have the stuff all over at least 9 of your fingers. The solvent cleans it right up. Physiologically it's pretty innocuous stuff. Besides gluing cuts together well, I've heard of people mistaking it for a bottle of eye drops, and it hasn't done any real damage. Inconvenient to have your eye glued shut for a while though. |

Absolutely. My mom is very allergic to aspirin. I'm not. I think as you said the same holds true for these type of chemicals. However in larger amounts other than a tiny droplet or two I spread along the 2.5cm cut all bets may be off. If you are a surgeon and are using it internally you would want the least possibilities of toxicity.

Thee are some newer formulations on the market which are intended to be less brittle, and thus able to handle more impact that the standard formulas. The one I bought (Gorilla brand) says that it's reinforced with rubber particles. I infer that the rubber both reduces stress within the adhesive during compression or tension (thus reducing the tendency for cracks to start) and also helps prevent cracks from propagating through the material once they do start. http://www.threebond.co.jp/en/techni...pdf/tech46.pdf has some details. I've made my first experimental use of the Gorilla rubber- reinforced variety, gluing a set of hardwood scales to a pocketknife handle. I'll be quite interested to see how the knife holds up with time. I know I'm taking a risk, not fastening the scales to the handle with small screws... but the scales are hand-finished olive burl and I just couldn't bear to drill holes in it. -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

Any application that does not apply a sheer force.
When I worked at a hi-fi store, we used to super-glue tone-arm bases onto the metal surface of the Lux turntable arm mount (rather than cutting screw holes into the surface). This allowed the mount to be reused for a different arm, simply by holding a block of wood against the tone-arm base and striking it with a hammer. |

Using a telfon "v" block would help alignment but I've managed without. The square cut (butt splice) doesn't work well. The problem is that the hardened super glue goes across the diameter of the rubber o-ring. If this diameter is compressed in any way, the superglue cracks, and the o-ring falls apart. This is especially important for internal o-ring seals, which use o-ring compression to maintain pressure. I've done bench tests on various methods and found butt splices lacking. It will work with a flexible adhesive, such as RTV, but not rock hard CA glues. Instead, try a 45 degree bevel cut. If you have an old 1/4" magnetic tape splicer, there's usually a form and guillotine blade suitable for the purpose. I do it without any alignment aids, which is good enough. My favorite cutting device is a safety razor or surgeons scalpel. When glued at a 45 degree angle, you get a larger surface contact area for the glue. The joint is also less in tension and more in shear, which does make it slightly weaker. I haven't noticed any measureable difference when I did some stretch tests. The 45 degree splice also allows the o-ring to be compressed in almost all orientations, without cracking the CA glue joint. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Sure. It worked fine for me gluing carbide to tool steel. Far from brittle, it was the most compliant of the three materials. It held a ton or so of force in another application, gluing stainless tapers together (for an ultrasonic drill tip). |

I use it on optical things often, because it's easily removed, like Duco cement except stronger and faster-setting. As long as you use just a little, it doesn't cause too much nasty frosting nearby.

I must adopt the storage in small airtight bottle with (non cotton) sachet of activated silica gel inside. Hopefully then it will be more amenable to squeezing out just enough to wet a needle point to transfer to the intended. |

No problem. Find a cancer stick igniter, and heat the stainless barrel. There will be a small puff of noxious smog as the CA burns off, and the tip is clear. It's quite easy to dispense just one drop with a stainless tip and quite difficult with a CA encrusted plastic tip commonly found in the hardware store CA products. If you want a smaller drop, try a smaller dispenser barrel. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I will try to upgrade my technique. "Jeff Liebermann" wrote in message ... On Thu, 2 Sep 2010 16:43:03 -1000, "John Keiser" wrote: I use it to splice "O" rings into custom sizes. If done properly [clean single edge razor blade, square cut] holds up well as a VCR drive belt, even in a swimming pool vacuum line leaf trap. Using a telfon "v" block would help alignment but I've managed without. The square cut (butt splice) doesn't work well. The problem is that the hardened super glue goes across the diameter of the rubber o-ring. If this diameter is compressed in any way, the superglue cracks, and the o-ring falls apart. This is especially important for internal o-ring seals, which use o-ring compression to maintain pressure. I've done bench tests on various methods and found butt splices lacking. It will work with a flexible adhesive, such as RTV, but not rock hard CA glues. Instead, try a 45 degree bevel cut. If you have an old 1/4" magnetic tape splicer, there's usually a form and guillotine blade suitable for the purpose. I do it without any alignment aids, which is good enough. My favorite cutting device is a safety razor or surgeons scalpel. When glued at a 45 degree angle, you get a larger surface contact area for the glue. The joint is also less in tension and more in shear, which does make it slightly weaker. I haven't noticed any measureable difference when I did some stretch tests. The 45 degree splice also allows the o-ring to be compressed in almost all orientations, without cracking the CA glue joint. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Some newer formulations can be brushed on; they don't go off as fast, and it's a lot easier to get the joint properly aligned than it used to be. Also, some formulations will work fine with things like paper or cardboard, too. Isaac |

If you use too much, the free surface outgasses like mad and you wind up with white plastic snow all over everything. There are 'low outgassing' PMMA formulations, but they're only low by comparison.

If you had posted to one of the model plane club groups you would have felt very much at home - in that hobby it is endemic David - with glue free fingers at the moment I think I will try introducing a dot of dye to the next tube I open ,as well as store in airtight bottle with silica gel. Won't be able to change the viscosity (lack of) but at least I might be able to see it. I was melding part of one socket into another to make a match to a non standard plug and a nice tight fit but that super capilliary action took the unknowing excess of glue about half an inch travel to where there were holes to the outside, where my fingers were. |
