Although I can see your point, CA is highly brittle. Maybe do some thermal cycling and flex cycling to be sure it won't cause surface problems down the road?

BTW, where did you buy the medium viscosity?

I think I may be hooked this is too easy

And he said the fumes didn't bother him! laughing6-hehe

On the last guitar I finished, I used thick viscosity (gap filler) CA to fill on the neck. It took less than 1/8 of a 2oz bottle to fully fill the neck. In about 5 mins the neck was filled and about 30 mins later I sanded back to wood and started the Danish oil finish.

Yes the only issue is the fumes, but with a respirator and a fan it's really not a problem.

Yes Michael, I'm with you, I'm hooked. It's so easy and inexpensive and very very quick.

That is very interesting.

I would really love to try that, but the only way I know how to buy CA glues is in these tiny little SuperGlue bottles at any hardware store. Does anyone know where I could buy CA glue inlarger quantity around Montreal, Canada?

Thanks!

Well, this IS interesting. Seems that CA has endless potential. I may have to buy some and try it.

A side note, I found a website that creates a kit for fingernails (guitarplayernails.com). I have used these nails for fingerstyle. Now, my favorite part is the fiberglass mesh and CA only. Great for strengthening existing nails. I wish I could find another source for fiberglass mesh. Same for the glue. They do the same thing and repackage the glue.

One more thing... any reason to suspect that FP will not work on CA filled pores? Seems to me I read on a website that CA filling before FP was beginning to take hold as a practice.

Thanks Micheal!

I thought CA glue could not be shipped outside the US (at least that's the case for Epoxy...)

I'll give them a call I guess.

Thanks again!

A 2oz bottle will be fine to fill an entire guitar and neck I think.

OK, just so I am certain, using the viscosity usnits listed above, which one is the proper one for pore filling? I know that thin stuff (guitarplayernails) really soaks into wood. Too thin.

BTW, if any of you play fingerstyle as well as build, I highly reccomend that nail building kit. Building and playing fingerstyle are not compatible hobbies (long nails).

I will ask again, does anybody know a source for very lightweight (sheer) fiberglass fabric?

Mike

Post subject:	CA pore filling
This weekend I did some testing of CA pore filling on four different woods and both thin and medium viscosity CA. the woods were IRW, Hond. Mahogany, Claro Walnut., and Koa I did a fairly large patch on each with both viscosity of CA. I have to say that I liked working with the Medium viscosity CA the process was done the same as if I was epoxy filling except that I used a utility razor blade with rounded corners. Once cured out I sanded back with 180p then hit it with the ROS with 220 Anyway my conclusions are that in most cases medium viscosity is great. Continuing to sand I found the pores fill good a deep and the pieces sand out smooth as a babies bottom. This was so easy and quick and actually much less trouble working cleans than I expected. One session and the filled some very porous IRW perfectly. I did not like working with the thin as it took too much and would seep in too quickly. Felt like I had to saturate the wood just to fill the pores I have resisted using this fill method in the past based on expense and the fumes but in truth with medium viscosity I doubt it will take but about one ounce to fill a typical guitar and with a fan blowing away from me the fumes were not noticeable at all while using a general propose respirator. I think I may be hooked this is too easy

Mike I buy mine through my local RC airplane club it has the clubs label on it but it is Starbond The club members buy in bulk and rebottle it with our clubs label. I really doubt brittleness will be an issue since I sand back completely to wood leaving the CA only in the pores. I know a lot of luthiers have been filling with CA for years I have never heard of a problem

Post subject:	Re: CA pore filling
A few years ago, I bought a set of worm hole laden BRW from a well-known luthier and teacher while at his shop. The price was very right! He showed me a quick and effective way to fill the holes that was amazing. He squirted the surface with thin CA and a few minutes later ran it through his thickness sander. The dust adhered to the not-fully-cured-CA and formed an undetectable fill. Very slick but the fumes are certainly something to be concerned about and avoid. I would recommend a charcoal filtered respirator however if in close quarters. And don't forget your safety goggles! I have not repeated this lesson but would not hesitate to do it again for a similar situation.

Oh Michael, get some help, next thing you know you'll be trying to buy all the ingrediants to mix this CA stuff up in a lab in your basement. You'll be stealing televisons and old ladies purses just to get that fix. One snort from that stuff and you're hooked for life.....lol For all us newbies, this was a joke, don't snort glue. It makes you where you can't type right. Love you Michael!

Alain, Langevin & Forest is in Montreal and they have what you need. I don't read or speak french but from looking over their website they have luthier woods and products as well. (You can send me beer as a thank you Just kidding)

Post subject:	Re: CA pore filling
Yep....a few years ago I stabilized and filled a 17" wide spalted maple drop top on a double-neck electric with CA. To this day there have been no issues with the top at all (polyurethane clear). Just make sure you get a good breeze going...

Hi Rod. I go there on a weekly basis. There are my main wood and accessories supplier. And they don't carry CA in large quantities, unfortunately... But I'd be glad to send you a beer anyways, specially since we're 'true flat tops' buddies! (Saw that on a different thread...)

Post subject:	Re: CA pore filling
Well sorry Alain. A 2oz bottle will be fine to fill an entire guitar and neck I think. Get the thick stuff as it doesn't set up as quickly. Work in about 3 square inch areas and it'll go a long way. Nice to see another true flattop builder here, we're a minority bro

Probably, but at 5$ to 6$ a 2oz bottle (that's what it costs around here), I figure that making about 1 to 2 guitars a month, I'd be better off buying bulk! Regarding our 'true flattop brotherhood', just give me a sign if any of those domed top builder want to beat you up or something, I'll join in the fight! They can be a nasty bunch!
