RE: Sig Hog Bipe
When using the cutting tool I found a few tricks.. Others can probably add to them.
1. Make sure your project can't move. Clamp it to the bench or something. VERY VERY IMPORTANT!
2. Start the cutting tool away from project. This way the start-up of the tool doesn't make it bounce around on the project.
3. I usually extend a finger from my hand holding the cutter to the project, it helps make any subtle movement easier.
4. When starting the cut, go very very slowly, until you're certain you have the cutter place/oriented correctly.
Good luck.
