I bore infrequently on my 7x12 minilathe. The last time I was boring I struggled, and the chips were not curls, but little tiny particles. At that time, I recall being told that was just wrong, that I needed to produce curly or continuous chips. I recall rotating my bar to get it to produce curly chips. Now I am trying to bore again, and I have tried rotating my bar, but am not having any luck producing continuous chips. Was I just lucky last time? Is there a system that I can use to set up the boring bar?
I read some articles on line about boring, and honestly they were discussing forces and angles and carbide inserts and relatively sophisticated aspects of optimizing boring, but did not seem to give much in the way of hints on setting up my boring bar. I have the usual Little machine Shop Chinese brazed carbide boring bars. I have selected the shortest bar to reduce vibration. I am trying to bore to 5/8" ID for a ball bearing.
Hints would be appreciated.
