As I stated, mine is a 12x36, for what that's worth. The distance between centers is a close approximation for the other half of the size. One of them will chime in eventually.ġ,2: It is definitely a 12 inch swing machine. There is a "sub section" particular to the Atlas/Craftsman machines. It wouldn't take much to throw one off balance. If that's not the cause, I'd look to the pulleys. Short of the head stock and bed frame, probably the heaviest part of the machine. You've had the chuck in hand, you know it's heavy. Not necessarily but I would look there first. The 4 jaw is only truely balanced when all four jaws are set to the same depth.

I would say to remove it and see if the machine still vibrates. Your's is a rather large 4 jaw independent chuck. Something is "out of balance", likely the chuck. One of your largest concerns seems to be vibration. Just needed to figure out how on a proper machine. Having learned on a "homade" machine, I knew what I wanted to do.
#Atlas lathe how to
I learned how to set the machine up with a lantern tool post and 4 jaw chuck. We didn't have a machinist as such in the crew, but the machine was used by a number of people in different shops. One of the ships I was on (in the 70s) had the electric shop on one side and a machine like your's on the other. There are always a few things that must be done the "old way" on any machine. I would highly recommend a quick change design although I do keep my lantern post handy for occasional use.

It is frustrating for a noob to set up but its' use goes back a hundred years or more and is well worth learning how to use. The "lantern" tool post that you show is the original design. For their size, they (both Atlas & Craftsman) are not the most rigid machines in their class. I think the Craftsman is a little "flimsier" than the Atlas, mostly from the size difference. Where the Atlas has a 10" swing, the Sears Craftsman has 12" capacity. Both the Atlas and Sears machines are essentially the same. The 101.07361 marks it as a Craftsman machine. Most particularly, a quick change threading/feed selector box. It dates from the early 50s but has a couple of newer modifications.
#Atlas lathe series
I am not that familiar with the series numbers. One that can stand my "sea stories" is well worth being a regular to. If you don't have one get a needle oiler. There are a lot of lube points and they need to be lubed every time you use your lathe. In watching your video to me it sounded like your lathe needs to be lubricated. I can not over stress how important it is to have properly ground sharp tool bits. Time consuming.Ī must read is Mikeys very, very long thread on grinding tool bits. Because I was and still am a newbie at this hobby I chose to make a norman style QCTP. You can never have too many tool holders. The big cost is not the tool post but the tool holders. You can buy them, $$$$$$$, or make one, $. Most people go to a quick change tool post (QCTP). Your video shows a lantern style tool post. One of your first decisions will be what type of tool post holder to use.

I have some 1/8" tool bits that I use with my small boring bars. The size of the tool bit somewhat depends on what you are doing. The 8" chuck is a common size chuck for your lathe. Tell us what you have and we will go from there. We love to help people spend their money on accessories for their lathes and other machinery. That will be the best indicator of when your lathe was built.
#Atlas lathe serial
I believe that 4670S is the serial number. Forum member wa5cab will chime in here with all of the info you need on your lathe. Your lathe is an early Craftsman 12 inch lathe. You will definitely get the answers to whatever questions that you have. Any other suggestions on checks, cleaning, tooling, etc.Are there limitations to using 1/4'' tooling? Just seems small in comparison to what I've been seeing online.This seemed large to me, is it the normal size for this machine? It appears that someone installed a replacement motor on this lathe.Looking though the Atlas DB yall have in the stickies, I only found one that matched and it was dated in the 1030s.Does the 101.07361 give a good indication of date of manufacture?.This first number is the swing,right? With a tape measure the distance between the center and table is about 6'', so wouldn't the swing be a 12''? Based on the 10D-247 and some other searches I've been doing I think I would call this a 10''x24'' lathe.so I apologize if some of these are very basic. I've been gathering up a few questions and this forum seems like the best place on the internet to get answers on these lathes. Will probably be making a good deal of tools with it as well. and I plan on using this guy to make fasteners, finniels, pomel nuts, etc.
