    Good video Mike, but I always turn the boring bar so you run the spindle forward (M3) to b0re a hole and turn it around and run the spindle backwards (M4) to do an O.D. bore.

    I have a product that has a .2495/.2498 O.D. and the only way I can do this part on the Tormach is to bore it. Otherwise, I would have to send it out and have it centerless ground.

    I also find these tutorials very helpful. Maybe in Part 2, Mike could address how to adjust the boring bar so that is aligned correctly.
