Just picked up a atlas lathe. Total bed length is 42", swing 12", distance between centers is about 28". I'm pretty green when it comes to machining. Could someone with experience on a similar machine please help me out with some questions I have. Thanks!
 
Start asking and I bet you will get many responses! If you are wanting to know the basic functions of your lathe it might not hurt to also look in the Atlas section of the Downloads area. We are definitely here to help if we can. :encourage:
 
There are many here running Atlas/Craftsman lathes, including myself. 101.27440 is mine. Find your numbers with a similar configuration, and post them up. This site is a fantastic resource, with lots of knowledge, and many helpful people. :big grin:

Welcome to H-M, I was going to say basically what @tweinke just posted.
 
Guys and gals here are gonna want pictures..you came to the right place to ask questions.lots of very smart people here..
 
I got it from my friends family. It belonged to a deceased family member who was described to me as an "inventor". I guess he had 31 patents. I can't find any markings on it because he refurbished it. I have a Chinese benchtop lathe that I can run but I wanted something bigger and this fell in my lap. I watched some YouTube videos and I think I'm starting to understand some things I was able to make a .060 total cut on stainless and was really surprised with a near mirror image.

I got the lathe, 4" and 6" 3 jaw Chuck's with both sets of jaws. 6" 4 jaw chuck, back plate, a very nice kobalt tool box, 6 starret dial indicators in various stages of usability, a couple cheaper ones too. Alot of calipers and mics. About 50 pounds of tooling, 300 pounds of bar stock. Lots of drill bits and home made tooling, a big air compressor. Another brand new 5 year old ge motor, some belts that I don't know what they're for and a bunch of other gadgets. What could a median price be for all of that stuff? To change the belts that control spindle speed from the small v pulley to the bigger one do I need to change belts? Only thing I can think of that I didn't get a good bit of are the atlas tool holders. I think I missed them in a drawer or something because there are only 2 of them and they are for 1/4 stock. I have a extra oxa qctp but I think it's a bit too small.

Where would I find that number. The only number I can find is one stamped on the end of the bed that looks like a part number and some smaller numbers cast into the big pieces.
 
It's an Atlas 12" no doubt about it. An AXA quick change tool post would be a good size for it, but if you have the old style lantern one you can use that for the time being. Yes, you move the belt to change speeds. Did you get any extra change gears with it? Looks like it may have a home made countershaft unit- more pictures would be helpful

How much wear on the bed is bad. With my basic measuring equiptment I can measure about .004 where the carriage rides the bed. Is this acceptable. It's only on about 5 inches closest to the Chuck.
