Well a mix of things in this episode, China drop and give me 20 
, I machine a spacer to test the new indexable tooling, GRRRRAHHHH #2 :madebooboo: and visit my local pushers. Here it is in pictures...
I was turning a 3/4 inch aluminum round, feed about .002 per rev at 360 RPM, the new Korloy CCGT 21.51 inserts cut like a hot knife through butter, this OD turning string was about 8 feet long.
Here I faced the end with one of the side corners of the insert, again this came off in a long unbroken spiral. I don't know if these inserts are the best but they seem a nice step up from the cheap carbide bits I was using.
This is the spiral from the new Glanze parting tool. I need to find a sharper insert, it cuts fine but left a hub of material on the spacer as wide as the insert vs a clean part off, it pushed the material forward into the bore area vs cutting it.
This isn't the finest feed on the lathe but I was happy with this finish.
I have this lathe stuff mastered...GRRRRAHHHHHH what the hell... :think1
kay I touched off on the face then backed out, nudged it left intending to face the stock...then sent it barreling left towards the headstock instead GRRRRAHHHHH. Got so wrapped up in how cool the new tooling was I forgot to pay attention to what I was doing. It cut a real nice chamfer though. lol
Here's the spacer, clearly I need something better than my old debur bit for smaller holes but all the turned surfaces came out fine. DRO report...I made a couple of these for practice. I brought the part off tool up to the face of the part, just touched, backed out moved left my target width of .300 plus the width of the parting insert and was .010 over. Second attempt I was .006 over. I'm obviously pushing the parting tool sideways flexing it a bit, I'll have to work on my technique a bit or figure out a tool offset in relation to the facing tool or something.
I visited my metals pusher and left $200 lighter today. 1.25 inch brass rounds and hex, 1.00 inch brass and aluminum hex.
Visited my wood pusher as well, these are spindles for a quilt ladder I'm building for my sister. I need to chuck these in the lathe and turn a couple sections round, I'm turning some brass end caps for these.
I was good I finished my yard/house chores today before playing with the lathe...went to install the 4 jaw chuck and who can tell me what's wrong with this picture?
Yes that's the correct D1-5 3 jaw chuck on the left, on the right is a D1-4 4 jaw chuck that does not fit my lathe :angryfire: way to go China. I'll be calling Grizzly on this. That's all for now, I'm at a stand still until I get the correct 4 jaw chuck or can find a straight shaft wood lathe gadget that grips the wood, I looked today they are all MT 1-2 taper.
