Hi All!!


I was wondering , with all the knowledge out there if anyone would know how to fix the yellow stain I got around the rosette from not accelerating the CA and it wicking into the end grain?

I think what others do is seal the trench to avoid the CA wicking up the endgrain. Don't no what the solution is to remove it once it has happened but will watch and see what others say.

(EDIT) Sorry, that is that they seal the rebate with shellac or lacquer sealer prior to glue up.

Cheers

I am not so sure that it is jsut the CA staining .. it is likely also leaching colour from the outer ring of the rosette. I like others, now use a generous ammount of french polish around and in the channel. I dont use it around the bidning ledge though, and seem ot have no problems there at all .. go figure. Sitka, at least for me, pretty much doesnt stain at all (pre FP days), but engleman and red are bad . They seem to go light yellow or even a hint of green sometimes if you forget to seal everything up.

Sealing is the way to go, but I guess it's a little too late to put the toothpaste back in the tube now. The only real fix I've seen is to route out the rosette and make it slightly larger routing away any stain marks. If the marks are too big this might not be a good solution. I haven't heard of anybody having any luck sanding them out.

I was talking to a local builder here who said he had issues with a certain brand of CA glue. Don't know what the brand is, but try using a different brand, that might help in the future. Don't know about getting rid of the stain now. Good luck.

I cannot say this enough , CA will stain spruce. Yes you may get away with it sometime but eventually you are going to ruin a top. I have yet to see this cured other than sunbursting.
   CA and spruce don't mix. Use the proper glue for the job. Duco is one of the better rosette glues

I had this problem on a rosette.I guess I was too stingy with the shellac,I don't know.It wasn't too bad so I just scraped a little and sanded and after finish you can't see it.I was lucky and now I brush the shellac in the channel and up around the rosettes edge about an inch. Others have had the stain not clean up . Good luck with it.

I sanded through a rosette once trying to get a nasty yellow CA stain out.I didn't even notice it until I was spraying on the finish. (The stain, that is.) It was a great learning experience to bite the bullet and replace the top. Lost a fine piece of euro. spruce and an expensive abalone rosette, but I was happy with the final result. I stopped using the thin CA altogether and am now using epoxy. The parodox of lutherie seems to be that a process that has worked well in the past will eventually turn nasty and bite you. I keep thinking I will finally make all possible mistakes, but it never happens.....
