Hi, I recently purchased a used Jamieson hollowing rig with the Hunter cutter. Bought if from here actually. And I really like it. It's the first time I've used a Hunter or any carbide cutter. I'm far more impressed by the Hunter than I expected to be.
That said, I'm having trouble understanding what I'm doing . More specifically, I'm having trouble understanding the positioning of the cutter. I understand that in some positions it can be used to "hog off" a lot of material, and in other positions it can be very fine.
I'm hoping someone can help me with this. Let's assume I'm doing a straight cylinder with flat bottom. I can extrapolate from there. If you are familiar with the Jamieson rig, essentially the cutter is on a short 3/16" bar. The bar is mounted on a circle and you can pivot the bar in 360 degrees. The cutter is mounted to the 3/16" bar at a "jaunty" angle.
So given all this, at what "time" (clock position) should I set it? Let me iterate the cases.
1) cutting perpendicular to the bed
a) aggressive
b) fine
2) pulling towards the tailstock, parallel to bed
a) aggressive
b) fine
3) create a center hole (say you didn't drill deep enough)
I think those are most or all the cuts I make.
I don't know if you have to have the J with the H cutter to know what I'm talking about but any help would be appreciated.
Thanks
