Hi Keith, actually a jigsaw blade. I ground the end on a bit of a radius and hold it in some small vise grips. The vise grips rest on the tool rest and the blade is brought against the wood at a slightly downward angle. With the wood spinning at 800 to 1000 rpm, the blade will screetch and chatter causing a pattern.
IMHO you've done an excellent job, glad to see a turning in the mix. I had considered doing a turning but I couldn't think of a way to incorporate the logo. Well done.

Good to see a few more entries popping up. Hayes, that logo is better than I could have done freehand on a curved surface, no forgiveness needed there

Sorry about the slip up, I knew you said jig saw blade but my fingers disconnected from my brain when I responded.
Did you hold the vise grip in your hands or clamp it to the tool rest?
The pattern looks perfect all the way around.

That's a nice looking box. Also curious exactly how the jigsaw blade works - that's a great technique.

The vise grips need to rest on the tool rest just like any tool. The rest needs to be high enough so the blade is angling downward. There are commercial chatter tools available that are more convenient but not having one shouldn't keep anyone from trying it.
I will post a photo tonight .

Had hoped to be able to photograph/film mine today, but the finish wasn't *quite* to the point I want it, so put one last coat on. Wheres the fun if you aren't running things down to the last minute anyway?

Ok Here we go outside the box a little bit but nonetheless it was fun to build and hope you all get a kick out of it. I tried to upload 2 animated gifs showing the progress but I guess I can only upload JPEGS. If anyone wants to see them I guess Pm me and I will send them or better would be tell me what I am doing wrong on trying to post them. I guess it needed a name I guess Tommy Gun

Crimony... a thompson submachine gun.

I predict that hand craftsmanship and time spent will be a factor.
Wyko's humidor will be a contender, and I wouldn't be suprised if a CNC/laser box doesn't get runner up. I didn't compete because i knew I didn't have the time to compete with the big guns. The thought of competing against CNC technology with a scroll saw and a dovetail jig is a bit intimidating.

Hey I said it was outside the box

Very cool! Neat how the parts fit together. It looks like the barrel was made with a large number of discs stacked up - is that right?
Member
The parts are all glued together there is over 230 pieces in the Tommy Gun and yes the barrel is a ton of small pieces.

Craig, that is a serious piece of work. Very impressive and unique.

Keith, here is how I hold the blade for a chatter pattern. There are really no rules so anything goes. It really only works on end grain. Different amounts of overhang, RPM, the grind on the blade, how you go about moving it to cover an area all affect the outcome

At about 800 RPM in about 3 seconds the pattern looked like this:
