Krazy Glue®, a super-strong, fast-drying adhesive was introduced to the North American market in 1973. When moving an old chanter sharp G hole, to make up the distance I dropped the hole, I dripped a small droplet of CA glue on the upper rim of the hole and sprinkled blackwood dust and it soaked it right up. A couple of these applications sanded and filed and there she be. I received a baggie of blackwood dust from a bagpipemaker when I had them do some other repairs.
I designed a big truss rod option specially for having less surface to glue, just 15mm sectors on the borders operation takes 15 minutes, and 6 grames of cianocrylate, it glues it mint, putting a good quantity of glue because it dries so fast that if bit glue, no time for pressing, but leaving a good hand of cianocrylate,,i press fretboard exactly 10 minutes and after that it is virtually impossible remove without cutting with a band saw.
This glue has been making a resurgence in some traditional woodworking circles because it has a lot of desirable properties: it’s non-toxic, it can be stained, it has strong initial tack that can be achieved via a rub joint (rub two coated pieces together and they will stay together), and it is available in several gram strengths (higher gram strength equals stronger glue joint) and color grades.
I can see where production shops that want to get parts glued quickly to get to the next steps,and where they can machine parts to the very close tolerances that this glue apparently requires, might find a use for it. But for the hobbyist, especially one who doesn’t always get micro-tight tolerances in his joints and for whom waiting overnight for a joint to cure isn’t an isue, I’m not sure I see the benefits of this glue.
Get the joint wet, add heat, and it will let go. This is very important for things like piano key bushings where you want to be able to re-do the bushings every decade or so. Use white glue or gorilla glue or pretty much ANY modern glue, and you will only do it once, and the next time you will have to painfully and somewhat destructively, remove the glue residue, assuming you can remove the felt or leather in the first place!
My own experience is that when there’s enough stress on a wood-to-wood joint that Titebond or similar won’t hold, I then go back into the joint, brushing as much Gorilla Glue into the crack as I can (not the best way to glue a wood joint, but in these cases the only remedy possible other than breaking apart all the other joints that did hold and essentially destroying the object).
Accordingly, it’s unlikely that you would glue the clamps to anything unless something spilled. The glue has already ate into your clear-coat, but if you’re real careful and take your time you may be able to remove the glue with a small cotton-swab or something like that. While I consider any film finish safe when cured”, I don’t think Helsman Urethane is a good choice for a cutting board. Use a warm, soapy cloth to remove the glue as much as possible after a few hours. Glues come in a wide variety of different tube sizes, depending on the type of glue you’re buying.
Commonly referred to as the cyanoacrylate or super glue fuming method”, small amounts of cyanoacrylate are heated in a sealed chamber. The whole point of super glue is that it works great when you form a really thin film of it between things it can bond. However, wood surfaces present a unique challenge when removing super glue because it is porous and can soak up the acetone, causing permanent staining and discoloration.
The apparent filling is just the foaming action of the glue and isnt strong at all. As I understand it, it’s a very non-aggresive formula to make it friendly for general woodworking joints, but just doesn’t behave like any superglue I’ve ever used. Use on materials such as paper and cloth, and semi-porous materials such as wood and pottery. The liquid form of this glue can often run, but the glue is also available as a gel that stays in place better. Things change in a big way once glue cures” which is more than just drying out. In fact, these inexpensive glues can achieve strengths near 4,000 pounds per square (PSI) inch when used on wood species with a high density.
A classic symbol familiar to generations, our packages feature a construction worker whose hat is stuck to a steel beam and glued by one single drop of Krazy Glue. My bottle of Old Brown Glue that I used to illustrate this article uses urea as well. Versions are available that are able to wick into tight joints but bond with reduced strength (because much drips out and much soaks into the wood leaving very little on the surface for the bond), or thicker formulations (gel) which can fill very small gaps, do not flow out of the joint, and do not soak so quickly into wood. When repairing loose braces or bridges there is no need to seek a stronger adhesive as carpenters glue is more than ample.
Super glue is the adhesive of choice you reach for when you want to bind together multiple surfaces in a strong manner and you want to do it near instantaneously. There really just isn’t a need for it. However, there is one application that I use expanding glue quite frequently: gluing on the fretboard. CA glue is also used in combination with sawdust (from a saw or sanding) to fill voids and cracks. This happens rapidly, often within seconds, making the glue bond to itself and harden.
Try a couple of things on a piece of scrap wood and you should find a good method. If you try letting a cotton ball or piece of rag soaked in acetone sit on top of the blob of glue, you might want to cover that with some plastic or foil to keep it from evaporating while it soaks into the glue. When using epoxy, work in a well-ventilated area, mix the glue in small batches, and be aware of how much of each resin you are mixing together. The handles can start looking dull quite quickly sometimes in my experience if they don’t have a finish.
I know nothing about the chemistry, but I’ve had very good results bonding brass tubes to wood, aluminum to wood, and wood to wood. Problem is people put it outside, it gets damp/wet and the standard glue stick stuff for glue guns sides not hold permanently. I use it to glue the body together, glue the neck on, and glue the binding on. Basically, I use it for everything except the few applications listed under the other glue types. White glue, yellow glue, and bottles of wood glue” are all likely to be PVA glue. Some proprietary products, such as citrus cleaners, will lift super glue from a range of surfaces.
After cleaning, wet any tissue used for wiping off glue with water and dispose of. When cleaning up larger quantities of uncured adhesive, apply water and allow to cure and then scrape up. Note this may result in damage to the surfaces. Don’t worry about swallowing liquid adhesive since the glue should solidify once it comes into contact with your saliva. There is A bowyer who has had similar problems with oily woods when using this glue and manage to repair them. If you enjoy woodworking then you probably also suffer from an addiction to tools.
Restore the sanded area with oil, varnish or paint, whatever finish the wood originally had. There are formulations specifically made to be used in place of ordinary wood glues, such as Nexabond 2500. Use the right glue for the job, even if you throw away the glue bottle afterwords. For lighter wood and porous materials, but can be used on plastics, glass and ceramics. Limba wood adds the soft feel and great control needed by today’s modern topspin players. Using the brush, work the juice around in circles over the glue until the adhesive starts to lift.
