This is certainly not the ideal way but, it's what I was able to come up with.  I really wanted to do this rosette!  I made a template of half of the non-circular portion of the design out of 1/2" ply.  I used a 1/4" pin to locate the center of the template onto the center of the uncut soundhole.  Brads were driven through into the waste portion of the soundhole to keep the template locked in place.  I used the shank of the dremel bit as a rub guide against the template.  I was concerned that the friction of this would scorch the template but tests indicated that I would be ok.  Not ideal for more than a few rosettes though.  I would like to come up with a more repeatable method.  An overarm pin router would be nice!  A stewmac circle jig was used for all the circular cuts.  I made all test cuts into 3/4" ply, flipping the template over after doing one side, and used this test piece as a form for the soaked in hot water purfling lines.  I mentioned before that I used a BWB purfling but all black would have given a nicer contrast.  After all the pieces were dry, everything was mitered and fit, then flooded with CA.  Router template guides might be an idea as well.  Anyway, that's how I did it.  Thanks for looking.

Hey Tommy that looks really good, excellent job.
I noticed we're neighbors sort of. I'm up in Los Alamos, nice to see another New Mexican here.

Nice.


Yes, a pin router would be ideal for that.  I made one with a drill chuck mounted under the table to hold the pin so you can use any size pin.  That makes it versatile and it has become one of my favorite tools.

Very nice Tommy. Mike Doolin has made a pretty simple pin router that would be perfect for this type of thing. Here's the link:
