Thanks all for the replies.

Richard, I'm not sure that I'm not having issues with this stuff. My left eye has been red and irritated for the past 3 days. I don't know if this is due to the CA glue or something else. Anyway....

James, I agree the look of open grain can be cool too.

HR, I agree. Don't like the look or sound of plastic. Those UV cured poly finishes that some people are using look good in pictures, but I think they have a plasticy feel in person.

I had similar issues when I finished my traveler guitar. Eyes burning and nose too. I ended up using a full face gas mask, which completely solved the issue. I love CA as a pore filler, it takes so little and it’s so effective! I spread it with 5mil nitrile gloves and my index finger :D

Btw your marquetry work is unsurpassed, IMO.

Cheers,

M.

Look up "sandblasting cabinet". It's an enclosed cabinet with a large window and 2 gloved ports your hands go into. You can make one out of window pane glass + large card board box from a washing machine, garbage bags for the gloves. Hook up a vacuum cleaner to duct the fumes up and away.

I smear epoxy thrice, like an animal......I rub CA wherever i need it. My rosettes are chuck full of CA. "Plasticized wood" should be my rosette material.

My last three guitars have a layer of 2 part epoxy on the top. I massage it into the fibers soupy thin, with my fingers -teeny bits at a time.
INSTANT body. The top, requires much less shellac as a result. i think Cedar really likes a little epoxy.

I've grain filled a couple rosewood guitars with CA....I love the stuff. I buffed out a back that was filled and finished with sanded thin CA - and I probably could have actually passed it off as a finish.... but it took on a real glossy "shipping tape covered" look. TOO thin. I don't like sanding it.

I pore filled a mandolin back with CA.
Easy, fast and very good looking result
but might be that I'll never do it again because of the nasty fumes.

I played a bit today with my black walnut headstock veneer and some thin CA just to try it. I applied a coat then scraped: three times. most likely needed three more to completely fill the pores. I thought I would aim for a glassy glossy head stock just for kicks. Don't think ill get there this time but fun trying and learning new methods.

An exhaust hood or something like that would be needed to pore fill a whole guitar with CA.

I hate sanding wood or anything else for that matter I just happen to be good at it...

As I mentioned earlier in the thread, you can get odourless CA glues. I haven't tried any yet, but I've got a bottle on order and will report back.

Jason, beautiful work, as always! What an inspiration.
To deal with CA fumes, I wear a respirator with organic vapor trapping canisters. Goggles help with the eyes. I also run my shop air filter which keeps the air moving. Plus scraping, not sanding, solves the dust problem. For me, CA pore fill is not problematic.

I have done this with gluboost fill and finish and get great results on ukuleles, I also use it on necks and headstock veneers. I do not use in on guitars as I found the large surface area makes both the fumes and the application a pain.
