My first experience dealing with Stainless Steel. Learned a few things I'll pass along so other new guys may benefit. A friend wanted a straight exhaust pipe for his 4 stroke RC engine in a model airplane he's building. I couldn't find any SS tube locally in the size I needed, so I bought a 1/2" x 4" Stainless steel bolt. The Grizzly lathe turned everything down to size, (.430"), including the hex head.
Next was the time consuming job of drilling a 5/16" hole in the 4 1/4" long bolt. Quickly learned SS heats up fast. Had to stop frequently to let everything cool so as not to work harden the bolt.
Now it's time to cut a 11mm x 0.75 thread. The G4003G was easy to set up for metric threading. About 1/2 way through I noticed the very tip of my new carbide threading tool broke off. Was a Christmas present, so I wanted to try it out. OK, no big deal, I'll switch to my HSS tool bit. Tool back on center, but couldn't see if point was in position to pick up thread. No magnifying glass available. Bingo, I'll use the smartphone's camera with zoom feature to zero in the point in the fine threads. Worked perfect. Zeroed dials and finished threading. Project complete. I love my Grizzly.
