<p>You hit the nail on the head - the friction of the polishing while turning makes one heck of a tough, thick, and shiny finish, and the oil makes the wood look really nice. I load a chunk of folded paper towel with the BLO, wipe it on while the piece is spinning, and add two drops of thin CA while it is still turning. (Needless to say, I have a face guard, nitrile gloves, and a work shirt on while doing this). I have wondered how such a finish could be used on a guitar, and the answer is…</p>

<p>Oh yeah, after a few applications, sanding with 600 grit between each one, I then hit the pen with micromesh and end up with a really nice finish. One of my favorites was curly maple dyed with a blue highlighter. <a href="http://storage.ning.com/topology/rest/1.0/file/get/2167746417?profile=original" target="_self"><img width="721" src="http://storage.ning.com/topology/rest/1.0/file/get/2167746417?profile=RESIZE_1024x1024" width="721" class="align-left"/></a></p>

<p>It turns out that CA is a catalyst that causes nearly instant polymerization of linseed oil. Michael Dresdner told me 10-15 years ago that it was discovered by accident - somebody dribbled CA into a container of linseed oil and was amazed at the sight. </p>
<p>Reminds me of the old Reese's Peanut Butter Cup commercial, "Hey you got cyanoacrylate in my linseed." "You got linseed on my CA. . ."</p>

<p> I use it to fix a split in my right hand thumbnail. It takes a long time for me to grow that nail and I rely on it for harmonics so if it gets a split (meaning it will soon tear off) I put a tiny amount of CA on the tear.</p>
<p> Then after it dries I sand it and it works great!</p>
<p> Great to do quick fixes on nut slots.</p>

I think all of the primary uses and considerations for CA with guitars have been listed, so my contribution is non guitar related:<br />

Ever get a fluffed up shoelace end that wont go through its hole? Snip the fluff off, apply some water thin CA, avoid the smoke as it cures, then trim the lace with a razor/sharp box knife, and viola!

<p>I've used CA for cuts for several years. I've switched to the generic version of Dermabond as it is a bit more flexible and doesn't loose adhesion as quickly. Make sure to wash the wound first and pinch it tightly closed. A Pentagon study during the Vietnamese war found CA to be better than sutures as suture punctures provide a point-of-entry for bacteria.</p>

<p>CA's best attribute is that it has incredible capillary action, the ability to wick it's self into the tightest of places. It is easy to apply, can give good results and it's fast. This ability is a tempting solution for many repairs but one should keep in mind that CA is mostly a non-reversible glue. Short of finish attacking solvent or mechanical removal, there is no way to get rid of it once it's applied. I have done enough repairs now to have had to undo a few repairs that I did and have…</p>
<p>CA's best attribute is that it has incredible capillary action, the ability to wick it's self into the tightest of places. It is easy to apply, can give good results and it's fast. This ability is a tempting solution for many repairs but one should keep in mind that CA is mostly a non-reversible glue. Short of finish attacking solvent or mechanical removal, there is no way to get rid of it once it's applied. I have done enough repairs now to have had to undo a few repairs that I did and have become more sensitive to the notion of "do no harm", or put another way, use no irreversible glue. It has it uses though and I keep a fresh bottle and pipettes at the ready.</p>
<p></p>
<p>Hot hide glue is always my first choice for any repair jobs where I think it will be enduring. Original Titebond comes out to, if hide glue is iffy because of a grungy joint or the job needs to more open time.</p>
<p></p>
<p>Things I use CA for have included: gluing frets, gluing shims onto nuts (I used to fill nuts slots with CA and bone dust but quit doing that and just shim them and re-cut slots now. Luthier's Mercantile sells .020" bone shims now, CA is great for attaching them. I don't use CA to glue the nut down and prefer a few small dots of Titebond for that), inlay work, including filling around the inlay and is also useful for stabilizing vintage inlay work. It is handy for attaching pads to clamps and other seat of the pants jig creations. CA is good for helping worried/ split screw holes, especially in softer woods.</p>
<p></p>
<p>I have used CA on occasion with a badly shattered head stock, as Rusty suggests, using it as a secondary glue. I have also had good results though, using hot hide glue with bad fractures that is watery thin. I heat everything first with a Red lamp, apply the thin hide glue and then hit it with compressed air in a short blast. I repeat this several times, working the joint open and closed.</p>
<p></p>
<p>I have been doing a number of Pegheds, geared violin tuner installations in banjos. They install with a two degree reamed hole and have tiny threads to screw then in. A lot of vintage banjo necks are made with Spanish Ceder or other soft woods that won't readily hold the tiny threads. Lace the prepared hole with CA and it will toughen the wood and get the threads to bite.</p>
<p></p>
<p>I recently glued a patch onto my belt sander dust bag with CA to patch a hole. I'm sure I could think of a bunch more stuff if I sat here long enough. It is not a fix all and does not have many years of use for a track record. Will it break down over time like other plastics? No one knows. How will it hold up in a hot car? Not as good as hide glue. Is it reversible? Mostly not. It should only be considered for use where reversibility doesn't matter. Instrument repair is stewardship, keep this in mind when your thinking about short cuts.</p>
