Anyone know where I can get a fly cutting bit simmular or like the one Cumpiano uses.

Martin sells one on their website. I also saw one at Rockler.

I got four from Grizzly. You have to grind the bits yourself no matter where
you get the tools. I like the grizzly version with a cutter on either side as it
keeps the tool ion better balance and has set screws that keep the cutters
from leaving the shaft if they become loose.

A word of caution: when using fly cutters make sure your drill press is set on
LOW SPEED. I had a shop partner that caught a fly cutter in the cheek after it
flew out of the drill press.   Luckily, he got hit with the only blunt end on the
tool. It turned out that he had forgotten to slow the drill press down before
beginning the cut.

Grinding them down sounds... complicated. Maybe I should use the popsicle stick.

Thanks Shane, it's This

The bits are pretty easy to grind on a belt sander. I have a little thickness
sander set up on my Rockwell 1 x 48 sander that made this job much
easier. There should be a picture in the archive.

I now have a dedicated cutter for .020 and .040 channels, another cutter
for the main ring that was as wide as I could grind from the stock blades
and one set up for cutting out the sound hole.

I like this rig for getting really clean cuts for single purfling lines.

Regardless of the one or two arm style fly cutters, do yourselves a favor and build a board with a 1/4" ID guide sleeve. Drill your top to receive the sleeve, slip the top over it and clamp down, attach the board (jig?) to the slots on your drill table and center the fly cutter (not yet running) in the guide. Then when you lower the cutter, the leading 1/4" drill will slide into the guide and receive support throughout the entire cutting operation. Makes for a very stable "machining" operation...and run at not more than 300 rpm.

The grinding's not hard at all, and the results are great. You can see the two bit profiles for two channel widths in the photo. Note the relief in the grind.

If you have a balance problem (make sure to use the proper speed <500 rpm if I remember correctly), you can put a counterweight on the other end. I think I used a small piece of lead screwed into the arm of the fly cutter at the opposite end from the bit. I don't remember the details - it was quite a long while ago. Even with that, it's kind of scary in operation, but the results are great.

I have one, tried it once, ruined a great soundboard, purchased the StewMac rig for a Dremmel and have been happy as a pig in slop ever since.
