Stan, I don't see where you've mentioned the type of bearing you have in your lathe. That can make a difference. I have what Robert tells me is the correct manual for my TH42, with Timken bearings. On

I now realize, from catalogue pages someone privately emailed me, that although the speeds given in the beat up manual I have are for a 12" they are also the speeds for a 10F. So, my confusion is

The badge didn't come with the lathe I have. Maybe it got trashed somehow over the years. The beat up manual I have that is supposed to be for the lathe, at least I thought so, has this image, but it

Sorry -- 618 was their six by eighteen inch lathe. Minimum speed in back gear 54 rpm. I have my grandfather's, delivered in '40 (or maybe '41? Robert knows because I used to have the delivery papers

Here is the badge that came with the lathe. It should also appear in your lathe manual. wrote:

Hmmm. I guess you are right. I was approaching it from the the other direction. I this case there would be no reason for the max spindle rpm of the 10" to be higher than that of the 12". I'm not

Jon, Thanks. From your response one would conclude that my lathe was a 16 speed. However, how does one reconcile the images in the Atlas parts list? As I mentioned, the images look like the pulley

Top speed of the 618 is about 3600 rpm. Again, it's for small-diameter work that you want the higher speeds. Yrs, d > >

Well, all 10 and 12" Atlas and Craftsman lathes I've encountered had basically the same setup. A belt with 2 positions from motor to countershaft, and then a 4-position belt from countershaft to cone

I think we all agree because I did take into account surface speed if you read my email. I am assuming the max rpm was set by Atlas to whatever it is by some considerations that have to do with

Surface speed for cutting is only related to rpm whether turning, milling, drilling, grinding, whatever.?Easy to remember formula: 3.82× desired surface feet per minute ÷ diameter of whatever is

The speed that matters is the surface speed of the particular piece you're working on, not of the lathe's capacity. So the issue at the large end is can it run slow enough and at the small end can it

Forgot to attach. Here it is.

I am not convinced my 10F lathe originally had 16 speeds. Robert had estimated its vintage is about 1953 or 1954. As? I mentioned in a previous email message my lathe is a real frankenstein. I did

My printer is only capable of printing 8.5 X 11 sheets. Thanks.

Originally, the nameplate was on the rear of the bed and the serial number, sometimes with prefix or suffix letters, was stamped into the top of the front way near the right end. I am trying to pin

If you have an Atlas 10F or Craftsman 101.07362, 101.07382 or 101.07402 or 101.07363, 101.07383 or 101.07403 and it was made in or prior to about 1945, please reply direct to wa5cab@... with the

I own three metal lathes, a South Bend 9 inch and two 618 lathes, one Atlas and one Craftsman.? I have read dozens of articles of DRO retrofits and have purchased inexpensive aluminum scaled LCD

I am going to do this on my 12x36, I need pictures!! Thanks, Ralph

Look on the tail stock end of the bed there is a plate it will tell what you have? GP
