    I would use a spring loaded for that job - as I have twin turrets, but I wouldn't expect someone with a machine like this to have one.

    Maybe you got one of those from McMaster too?

    No, I don't have a spring loaded center. I was able to dial down the tailstock thrust pressure to the bare minimum for this job.

    I haven't mentioned my small CNC lathe (Junior) since I got in installed. Well, here's the start of that story...

    After the machine was set into place by the riggers, I noticed I could take off the rear sheet metal guards and gain about 10" of much needed floor space. Sweet!

    Anyway, I began stripping off the covers to clean the overall machine and get inside the machine's tool changer as well. HGR sent me very detailed pictures of one dirty ass machine. I knew I was going to be cleaning for a while, but damn.

    More to come.

    No, just had to go into my real job this morning. I'll finish the story with the rest of the pictures when I get home. Those pics are from 2016. I'm not going in exactly chronological order. Didn't mean to add confusion to the story.

    Just meant that you have spent more time here this past few days than seemingly the last year.
    I have noticed your absence.

    Must have fallen off the wagon....

    Got it. I still read the board a lot, but haven't posted a whole lot. When I do post something, it's usually in the Mazak section helping someone. This thread will up my post count for sure.

    Swirl in to the cylinder has been proven to greatly increase volumetric efficiency.
    Isn't this the premise of the Dodge "Hemi" motor...??

    I think that is for the benefit of more surface area?

    The paws in the picture belong to Ruby. She's a Red Bone Coon Hound about 5 years old.

    Ah, so it seems that Mr. King aint the only one in the area with a redneck streak.

    And just how many coons y'all got down there?

    I bet that howl sounds a bit out of place in the city?

    Back to Junior, I took off the chuck and cleaned and greased it, then I took off the tool block that holds the milling spindle and took it apart. The bearings in there were shot so I bought all new parts and O-rings for it.

    The dog behind the lift was Scarlett. She passed away last year. She was not a coon but a Vizsla.

    I bought four Filtermist units from HGR back in 2015 timeframe. I cleaned and painted this one to match Junior. I bought a side discharge plastic lawnmower grass chute off Amazon and used it as the air intake on the back of the toolchanger sheet metal enclosure. I then wired the Filtermist into the electrical cabinet and used a spare VFD to control it's ramp and running speed.

    I got Junior reassembled and trued up the hard jaws with a ceramic insert. I then aligned the headstock to the Z-axis via test cuts on an aluminum bar. Things were looking good.

    I thought the machine was ready to go, but upon running my first program, I noticed the machine was "hunting" for the tools. The machine would index the tool changer two full times before it found the appropriate tool. Damn. Something was wrong. I messaged Wippin Boy from the board and he thought it was the proximity switches. I had to tear into the machine again to gain access to them.

    The proximity switches were in good condition. However, it turns out the mounting bracket that holds them was slightly out of adjustment and the gap from the prox switch to the index gear was too big. I reajusted the bracket and the machine was indexing properly. Cool! Time to make some parts.

    Here's the first parts I made with Junior. Nothing too exciting, but it was a milestone. I machined them from HT 4140 hex stock and ran the second OP facing the back and tapping the hole in Mini Me.

    Here's a neat tool I made for Junior. I made one about 10 years ago for my QT10N at work, so I know I needed one for home. It's a combination interchangeable cut off tool / bar puller. This saves time having both tools in one and also frees up another tool station for something else. Makes running production jobs automated.

    The tool is an old Sandvik quick change head called a BTS system. Hard to find now as they are obsolete. I machined up an adapter and welded the BTS holder to it and also bolted the bar puller to the back of it. I can use the puller with a 1/8" cut off blade, or if I'm doing smaller parts, I can swap over to a grooving holder and use a .062" wide groove insert to cut off the parts to save on kerf width.

    Here's my first long running job I did with the system. 110 pcs is high volume for me.

    That takes:

    A) A lot of X travel

    B) A lot of turret to way cover clearance

    !!!

    This machine has tons of X travel and clearance around adjacent tools due to the machine having milling capabilities. You are right, I could not clear a tool like this on a turret machine.

    When I bought Junior, it came with a knurling tool in the tool chain that had really fine rollers. I never thought I would use it so I set it aside. Well, last year I got an aluminum knurling job to make some small knobs and the print specified .030" pitch knurl. Well, look at that! I have the tools to do this job. Parts took a little dialing in, but they ran sweet. I finished the back side on Mini Me and tapped the holes by hand.

    Here's another long running washer job I did from 4140HT for the same guys. Junior is starting to pay for itself.

    I recently installed an aftermarket oil pressure gage in my 2001 Dodge Ram 6 speed Cummins. The oil pressure sender from the factory was 14mm x 1.5 and the aftermarket gage had an 1/8" NPT fitting. I wanted to use the oil port where the factory sensor went, so I machined up an adapter that mirrored the factory sending unit. This is the first time I used the live milling on Junior to mill the hex. I tapped the back side on Mini Me.

    I used a kit from Genos Garage to mount the gage into the dash where a little cubby hole used to be.
