Stumbled upon a Craftsman 101.21200 Lathe

[bama7]

One of the motors I have had the ability to go clockwise by swapping the wires around and it worked! I was looking yesterday for another motor and a guy called me today. He has what I want for $25. I plan to head that way tomorrow morning. That will give me two motors for the two lathes. Can’t beat that. I am still waiting for the new belt for the 101.21200 and some parts for the 101.07301.

After swapping wire to get the motor to turn clockwise I installed the motor under the lathe table top with the pulley to the left end, headstock end. Well I had to swap the wires back to have the motor turn counter clockwise. Maybe I am now a two wire electrician. Nope not a chance. I almost forgot to mention this is the 101.07301 lathe I am talking about this time.

Which direction the motor needs to turn depends upon whether the motor is mounted straight behind the headstock and countershaft with the pulley on the left end of the motor (most installations) or to the left of the countershaft with pulley on the right end of the motor as shown on some early 6" installation drawings.

Here are some pictures of how and where I mounted my motor on the 101.07301. It seems to work well and is out of the way.

If you need a belt (and it looks like you do) US bearings and belts has 2L belts for cheap. I think it's about a 29"
I'll go check mine and see how good my memory is

ps yep it's 2L 290 made by Pix (India)
pss I see you have the milling attachment but I wouldn't plan on doing a lot of milling on this lathe- the spindle drive coupling is a weak point

I recently acquired this same lathe (101.21200) but it appears that the headstock bearings need replacing. Do you know the bearing specs of the part number for the bearings? I tried looking up the part number from the parts list but was unsuccessful. I believe that there is a manufacturer number for the bearings as I have replaced similar bearings on other machines. I would like to order the bearings in advance so I can do the job all at once. Thanks

Here's my thread on this model, there may be some bearing info in there.

Just added a 101.21200 to my shop out west

I've been suffering lathe withdrawals since my Seneca Falls Star 9" is 2000 miles away. I found this little guy on Craigslist, not the upgrade I've been hoping for but it should keep me busy for a little while. She's rusty but the spindle turns smooth so hopefully just a clean-up and paint...

FYI, the 101.21200 is the same except for badges as the Atlas 3950 and was also known as the MK2 6". Introduced in about 1974, it has ball bearings on the spindle, not tapered roller bearings. And except for being about the same size and using about the same tailstock and bed casting, does not look anything like the 101.07301 shone in the photos just above. The 101.07301 looks similar to the Atlas 618 except that it has bronze sleeve-type spindle bearings and for some reason stayed with the 2nd version of the 618 Countershaft, instead of shifting to the third version when the 618 changed. Also, the 101.07301 was replaced in mid-1957 by the 101.21400 which is the same except for badges as the 618. Why Sears assigned an earlier model number when they switched to the MK 2 no one knows.
