Here`s a poor pic of the rosette that I made today. Actually it`s the second one, as I trashed the first when I sanded through the lines only to find that I didn`t have them seated all the way down when I inlaid them. You vets out there are probably chuckling about that aren`t ya? Gotta live and learn, huh?
Sorry about the pic quality. I need to get a better camera. Actually confiscated this one from a box of garage sale stuff.

That looks like one of those 'spirograph's' that showed up in a recent thread. Only in this one the lines appear to be curving 'away' from the center, rather than 'around' the center of the soundhole. Interesting. I thought about that approach myself, but never got around to plotting it out, can't find my compass. I'd like to hear about the process too.

Here`s my approach at it...

First, I Made a shallow cut around the outside diameter so that I could see how much arc I wanted to put into this design. After deciding, the arc is cut, running past both tangents. Then the center is cut loose so it can spin and a piece of .050" purfling is put around the diameter of the jig to compensate for what I lost to the bit.

Now the jig is turned so that each cut is half the distance accross the arc. (If I had it to do again, and I probably will, I would have made that distance 1/4). Clamp the jig down securely. You don`t want it to slip from here on out. From there, it`s off and running. As each slot is cut, remove from the jig and CA the line into it leaving a length of about 1/8" protruding on each end. These are the tabs that go into the slot in the jig, and determines a definite locating place for the next cut.

This is what I got after one round. I had to re-adjust to get the next set of arcs centered on the previous. That was the reason for only adjusting the jig by 1/4 of the distance accross the arc at the onset.

Here it is after the second lap.

After setting it into the top and adding my .50" rings to it. Kinda pretty, huh?
Man that last pic sucks. I`ll see if I can get hold of a better camera tomorrow.

What are you using to make those cuts? Can't tell from the pictures.

Just a Dremel with a circle cutting attatchment. Using a .050" dentist`s bit. BTW, I`ll be going to a place that sells these bits for cheap. If enough people chime in, I`ll make sure to get a bunch. They also come in .030", both with 1/8" shanks.

Coe,

Ok, I'm 'in' for some of those bits, both sizes.

That must be the Dremel brand circle cutting jig, yes?

I've been toying with an idea of using Dap Plastic Wood for inlaying.

Thanks,guys. I thought y`all might like this one. It looks alot nicer now that it`s done and cleaned up.
Robbie, That`s walnut cut into .050" strips. The first one I made was walnut w/maple lines, and looked better IMHO. I`ll probably do it again using .030" lines.
