Re: Don't want that taper

I assume that with the leveling operation, I'm only looking for twist along the ways? Put level across each end of the ways and make sure it matches? I'll try my new Bison 3 jaw chuck to test the collet theory. thanks everyone for your input. I'm going to be a little busy doing other things this wee...

Re: Don't want that taper

What do you mean by temperament?
Can you tell me the issues you see with the tool. I'm not real experienced at grinding them.

Re: Don't want that taper

Still get the taper without the tail stock and 1" stickout with 3/4" rod. When I used the dial indicator, the tail stock was involved. Indicated ways parallel to headstock. I'm beginning to wonder if the live center has some slop in it. It's a cheap one I've had for a long time. I'll check that out.

Re: Don't want that taper

I would think that run out would cause a smaller diameter at the end away from the spindle. This is a smaller diameter toward the spindle.

Re: Don't want that taper

More information... - I'm using an HSS tool that I ground myself. - Spindle speed is 500rpm. Feed rate tracks with spindle speed, but chips are far from looking burnt. I'm seeing this while taking very small cuts. Feeding manually at very slow speeds; the tool still tracks at a taper. - I'm having t...

Don't want that taper

I'm cutting a 2" of a 3/4" round rod down to .7200" on my Monarch 10ee. I've had the lathe less than a year, but this is the first time that I need to go for sub-thousands accuracy. The .7200" section I'm cutting is 2" long. I'm seeing a taper along the 2" of 1.5 to 3 thou diameter (diameter always ...

Undercutting A Drilled Hole

I want to undercut at several levels in a hole I'm drilling. It's a 3/8" hole in mild steel. Every 1/4" through the hole, I want to cut a round slot that is about 1/2" in diameter. I don't know if this is possible nor can I visualize what kind of tool would be required to do it. Any knowledge on thi...

Lathe Inserts

I need to stock up on lathe inserts. I typically buy tools from MSC Direct, but my problem here is that they have so many choices of coatings, etc, for inserts, that I have no idea which way to go. Can someone point me to a simple tutorial that helps me understand what coatings are suitable for what...
