3D Single Pass Skinny Jenny

I have a topo map to carve, and since the make depth of cut is only .15 inches, I’d love to be able to carve with just a single finish pass - no roughing. I have the skinny jenny TBN bit, does anyone have experiece if I can get away with a .15 doc and a 15%-20% step over with this bit? I’m cutting red oak.

What’s the material being used?

You skim-read :grinning: Red oak

Yes, the skinny jenny can be used without a roughing pass at that depth no problem. Feedrate 180 ipm, plunge 120 ipm. Your detail at 12-15% stepover wont be as smooth as if you were at 10%

You added it… Haha… Wowsa… How did I miss that.

Thanks, Mitz. BJ, you missed it the same way I miss most things these days…at the same time you are reading, there are a jillion other things going through your head…where are my car keys? what’s for lunch? how many women are in the pit right now? do I have enough lotion?

You are only ever going to get 118.11ipm with that bit no need to set it any faster unless you have altered your zaxis accel rate. TBNs are beasts when it comes to one pass finishing. I have a video of a 1/8tbn cutting .65doc in pine in one pass.
