Just found this thread - watched your videos - very impressive......
I am a wood tuner - just barely - still learning my lathe, etc - speed control, tool manipulation, etc is all done by hand.
Naturally - I has questions....
Are you using carbide tools?
How smooth a finish can you get?
Do you have the equivalent of a skew chisel for a cutter?
Your wood is what species?

I'm not Salty, but I can answer one question. The finish is as smooth as he cares to make it depending on the resolution and stepover when doing CAM and the quality of the source file. I would suspect for wood plugs its probably more efficient to leave it slightly rough and sand rather than to use a ton of machine time to get a near perfect finish.

Wood species varies from pine to cedars to birch and maples.
Finish is dependent on how you run the machine. If I want to run it wide open it's going to give a much rougher cut. A slower speed will give you a cut that requires only 120 grit paper to sand. Like this:
That's a bit over 7000 rpm, cutting at 4 speeds in the program as you can watch from the speedups and slowdowns. Yellow Birch rough to finish one pass with 2 axis. This particular body can be done pretty efficiently and doesn't need the whole machine. I can do these in 14 seconds each un-sanded with a 80-100 grit sand finish needed or I can slow it down a bit and save some time sanding like this.
Tooling is all carbide. This particular bit has over 1000 bodies on it already and is just starting to get dull. No hard crashes though.

Scott, That is sick...
Where did you get your servo's and lineal bearings etc from? I am still toying with the idea of making a non-concentric bait duplicator but lack a quality supply of odds and ends!

Thanks guys. Some of the original videos got deleted in cleaning up stuff online. This machine has made alot of lures now. It's been very reliable. Dust collection continues to be an issue. Needs a collector 3-4 times bigger than it has now.

A cyclone separator can help a lot. I don't do a lot of wood, but one of my buddies does a lot fo hardwood on a 48x48 CNC router, and he uses a 55 gallon barrel with a DIY cyclone separator btween the shoe on his machine, and the vacuum he is pulling air with. He says with hardwoods 95% of the chips drop out in the barrel, but when he does MDF he quickly plugs the filter on his vacuum.
