The Home Machinist!

Just because it is a negative rake tool holder or insert doesn't mean that it can't have a positive cutting edge. There are both roughing and finishing type inserts available, although normally, negative rake tooling is for use as Harold describes. Perhaps what you have is a sharp edge finishing typ...

I do see the occasional 3/8-16 mt2 piece, but they tend to be 2-3x the cost of the metric import tooling.

Why not just sell your present 3/8-16 tooling and convert to metric draw bar and tooling if your 3/8-16 tooling is worth that much and so difficult to find?

An Arcsecond would be about 19 millionths at the perimeter of an 8" rotary table. (If my math is correct...)

The only real negative of a turret is they're pretty much useless for one-off parts. Mine gets used constantly regardless. I've never looked at another one, but mine has 8" of travel with a ruler on the front side with an adjustable pointer so it is not always necessary to set the stops. For a quan...

Looks like a great project!

Best wishes Harold and take care. You've made a difference in my world of machining (and perhaps a little more) and I really appreciate the opportunity to benefit from your knowledge and experiences that you so generously share.

Well said, and I couldn't agree more!

Thank You!!

If you need two of them to hold something and are concerned with alignment, why not just use one larger vise?

Hopefully, all will be good and everything will continue normally.

Thank you for letting us know!

From where do you obtain the Mobilmet oil?

I bought a couple of 5 gallon pails from Enco.

A quick search turned up 5 gallon pails from MSC, and a number of places with 1 gallon jugs.

Water based.

I use Mobilmet 766 oil in my lathe flood system for stainless.
