Received an e-mail today saying that my 14X40 had shipped, The wait was longer than expected, hope it will worth it. I am really looking forward to the lathe.

The lathe arrived with no problems, crate not damaged. Roadway did a great job! Well the lathe is even pretty to look at. I have leveled the lathe and have been learning the controls. I am running the spindle at different speeds un-loaded as well as the gear box. This is in addition to the recommended break in procedure. Made a few cut s on Al. Friday to see how the DRO works, never used a DRO before. The headstock is quitter than I expected. And the change gears are also smooth and quite. I am going to make some test cut on steel (drill pipe) this week-end. I am more than pleased with the lathe. Long way from a 13 inch South Bend that is now for sale.

try reposting that. I don't see a picture, all I see is a little red X.

If you need a place to load your photos to so you can link them here, I recommend photo bucket.

Been learning the lathe, cutting a lot of air breaking it in. I am going to purchase carbide insert tooling this week--time permitting. I am going to get help learning to post pics next week.

Have not had time with the lathe. Been doing some work on airboats. Followed a 572 inch Dart engine build--made 701 HP at 5200 RPM (bad boy) Right now I have to decide if I want to keep my AXA QCTP or use the BXA size that came with the lath. I have a lot of tool blocks for the AXA, 2 expensive insert holding blocks that I like to use.

Helo together,

I bought mine in 2006/2007 and I was a little bit disapointed. I bought it with the a lever style collet closer installed, which wasn't. There was not much help from Matthew either, so I had to figure it out by myself.
Also the lever for the feed directions is a pain in the ass to operate, because it's difficult to get into the notch.
The tail stock quill is way to sloppy.
The plate underneath the the tail stock is not clamping right either

I forgot to mention that the feed selection lever at the carriage is very difficult to operate/change from longitudual feeds to cross feeds

Best regards

Klaus

Interesting. Can you take pictures that show the issues you are talking about? I am curious about how much slop you are seeing in the tailstock quil.

I have a question. The 14X40 HD manual calls for Mobil DTE Heavy Medium oil to lube ever thing. I have not run a machine that did not require Way oil for the carriage and cross feed. Is this common for PM lathes, Any comments about not using way oil. Thanks Folks.

No expert here, but from what I have read and used, I would see no reason not to use Mobile Vactra #2 oil or Shell Tonna S2 MX 68 on the way sliding surfaces. I notice a big difference in using way oil vs ISO 68 lubrication oil that I use for the gearbox and bearings. Some machines specify ISO 68 all around, as it may be easier to use/stock one oil. If that is the case, then the Shell Tonna would be the best fit. Otherwise would use the Vactra #2 on the lathe ways. Evidently Vactra #2 is less tacky then the way oil it replaced which was Mobil Vacuoline 1409, but is less likely to get gummy over time. Vacuoline 1409 also EPA issues with the tackifiers, and there were issues with CNC type machines due to the increase carriage speed.

This is not specific to the PM/QMT machines, as other machines (like the PM1340GT, ERL, TRL) specify different oils. Your machine looks identical to the Jet GH-1340 and 1440 models, their manuals specify ISO 68 oil for everything. Other manuals specify something like Mobil Vactra Oil No.2 oil for the ways. Grizzly on many of their lathes just specifies ISO 68.
Example for G0776:

I have not found the tailstock Quill to be sloppy. Did you check the clearance.
My lathe does look like a Jet GH-1340 and 1440 models and the motor is Labeled JET---Go figure. If it is the same, seems to be a good buy from Quality Machine.

I have been using the lathe making a few small parts. Two shafts to build an elastic bandage wrapping machine that weight lifters use to re-roll
ace type bandages. Used the lath to cut " Birds mouths" in some pipe couplings for welding to 1.75 tubing. Learning to use the DRO. A DRO makes setting the tapper attachment easy.
Does anyone know how much oil the Head stock holds-- just a rough idea?

have been working the lathe turning a chuck adapter for a new 3 jaw chuck that I have. Just to see, I took a few cuts at .250 per side.
Still trying to learn how to posy pictures.

Anyone have a picture of inside the drive gear cabinet on the head stock? I'm curious on how easy it is to do gear changes with the full enclosure?

Thanks,

Jay

Send me your E-mail address. I have a couple pictures I took with the cover off when I changed the oil for the first time. I also needed to drill two holes to mount a chuck guard on the head stock. Wall thickness was unknown. Are you having problems with the head stock or gears?

Thanks. I sent you a PM with my email address. Also if you don't mind... can you tell me what the length of the spindle is through the head?

Thanks Matt!

A safety switch in the door? Really? Like the rest of the machine isn't dangerous. Must be a lawyer thing...:rolleyes:
