I had some nice burl wood from RC Tonewoods for the rosette.
At first I tried to use the manual cutter to cut it, but at some portion the wood is brittle and for that part it literally crumbles to pieces when I cut it.
So I resort to my circular routing method and it works fine.
Then I began to scribe the circle for the rosette.
At first I use my manual cutter to scribe and concentric circle then chisel it.
I discover I was too slow... (I didn't have much time to do it)
So I resort to my B&D RTX (dremel equivalent) with the circle jig.
Thing got fast and because the outer and inner rims were scribed, the circle didn't appear too bad.
The inner was remove using chisel but much less materials to removed.
Then I threw in some PVA glue (dries transparent) and glue and clamp the rosette.
The fit wasn't too great but since there will be a purfling border I guess it should not matter too much.
The purfling channel however must be perfect, as there will not be any more room for error.
After I removed the clamps, I check that the burl rosette was inlaid quite nicely.
I shave it down using my Stanley new sweetheart low angle block.
After that I began to scribe and inlay the inner channels.
After scribing the outline of the channel, I use the RTX to remove the materials.
I test fit the purfling and it went it snugly.
Now when I was doing the outer ring I made a terrible mistake...
I switch to a 3mm router bit I thought it was a good fit for the purfling.
What a mistake I made.
First I route too deep and 2nd I routed into the rosette.
What is worse is that I have already scribed the channel...
Now the channel is too wide at some parts.
What can I do at this point? nothing.
I just glue in the purfling and indeed the outer channel is too deep and it can't stay there.
