I considering removing my existing sound hole inlay ( the box is all assembeled), because I don't like it. Am I crazy, is it doable? I guess I would
have to make some kind of a plug for the sound hole, nice & snuggy & do the circle router jig dohicky??

I think someone did that not to long ago and posted the procedure. But I could be wrong.

Well, I recently had to do another one, and this one was to replace a whole rosette with another AND also the spruce in between rings. I had used cyano to glue in the center inlay and it turned the spruce yellow. I thought that I would have to replace the top, but gave a replacement rosette a try first. Here are the photos. My first thought was to leave the outer ring and that was a mistake. I didn't document the whole process, but the essentials are there. As an afterthought, I probably would have cut half the outer ring and put the new seam for the spruce plug there. I missed perfect fit of the plug by a couple thousandths and cut a little off the outer ring. so I had to make it B/W/B/W/B.





I was fortunate in that I always use a full crossgrain doubler under the rosette so that I could rout right down to the doubler. I glued the routing plug in with a few dots of cyano after rotating the plug to find the spot that would leave the outer ring intact. The new plug of red spruce was matched to the grain of the old as closely as possible and made of two pieces so I had the center seam and also the slight amount of run out to match the top.
A block support was added to the new plug and it was glued in.





Then I was able to rout a whole new rosette. Originally, the outer ring was intact, but I lost a few thousandths somewhere with the new plug.



After the new rosette was in, I resanded the whole top.



Hindsight being 20/20, I wish I would have hidden the seam under the outer ring and just routed the ring over again, but it turned out pretty well, and I decided to keep it as is...

Haans,
Thanks for that. I suspect I may have to do the same thing.
I'm curious about that little bit of cutout for your fretboard. Is that something you usually do?

I forgot to add that in order to get the support block in exactly the right spot to maintain perpendicularity, stick the pin in your rosette routing board, followed by the plug (upside down) and last the block with the hole in it gets glued on to the plug. Then you are sure the pin is vertical to the plug.
Mike, the bit of cutout is for the T/R barrel nut under the fingerboard. Have to do it for dovetail joints.

So is it a bad thing if I thought something was posted 2 months ago but it was really 2+ years ago?

I rescued this rosette sand through using a plug similar to the one Haans used.



I made the plug from a piece of pine using my rosette routing jig. It fit, but was a hair lose so I wrapped a layer of tape around the inner plug section to get a tight fit.



I was a bit off from my original circle so I added a black trim around the herringbone. I probably should have done this originally. Sometimes it is nice when a fix comes out better.
