Whatcha got? Lathe, mill, any other shop tools, pics of your shop and tools, details, techniques questions How do I ?? How I did....
I'll lead off; my dad's ole southbend has followed me around for 25 years now.

But got all fancy and bought a Grizzly 4003,

Huge difference from the old, small, and rather worn, South Bend. But I have no training or education on the use of the lathe so I'm on that steep learning curve.
I'm liking the QCTP but the insert holders that came with the lathe were weird or improperly machined, the insert angle was just plain wrong?

In order to use them for typical square face and turning cuts, the tool post needed to be skewed off of square to the chuck which just made no sense to me. The grizzly boring bar holder that uses the same insert has the "correct" angle,

which seems to be the 80 degree "point" should have 5 degree back angle on each side, kinda like this,
I kinda kludge fixed them by grinding an angle on the rear of the holder so the insert has the "normal" 5 degree angle to the surfaces, I think this will work fine for now.

I got a few of the Grizzly carbide inserts which are also a bit unusual in that they are machined for left and right hand use.
Well that's a wandering first post in the thread eh?
