Dang, I just ordered 3 new AL-4 bits. Good thing McMaster Carr is so cheap! I'll order some AR-4s. Thanks dude!

thats correct, I ordered AR-4s and the difference now is what I have been missing. Main thing also was the cut direction I moved the bit. I was going from Right to left. Big no no. Going the right way, worked wonders.

also, a nice set of diamond files work well to keep the bit sharp too. I have a faq on how to sharpen it properly from Big Jim if you want a copy. He never used diamond bits from what he told me.

Alright! Now that's what I'm talking about! This is how the lathe was meant to cut. Thanks for your help guys. I got my AR-4s yesterday and today I cut my first comm that actually looks like a new penny! Sooooo smooooootth!

Cain, are you use AR4 for integy super lathe 3?

I just ask a machinist to fix my lathe, They know all the things that need to be adjusted and have the tools to make sure its right, and they can examine your bit and tell you if it needs to be sharpened or replaced. That will get you the best performance out of your lathe, and the performance will last a very very long time.

Super Lathe 3 uses an AL-4 bit according to McMaster-Carr. Even though the Super Lathe 3 cuts towards the right, it uses a left hand bit because the bits are installed upside down from industry standard. This is the source of much confusion...

If you still don't believe me, just match your bit to the illustration on McMaster-Carr's "Single-Point Carbide-Tipped Tool Bits" reference page.
