Re: Welcome to [email protected]
Robert, you pose a very interesting question here. Other than basic conservationism on the part of customers and producers I do not see why! But then the basic design of our lathes was done in an era

Re: Welcome to [email protected]
From the photo of the left hand spindle bearing, your machine was obviously a Craftsman 101.07301 (built by Atlas for Sears from 1939 until mid-1957). The highest reported serial number is 030965. At

Re: new guy - old 618
There should be a thrust collar with set screw trapping the bearing against the pinned ring. I have not done it but I presume that the way to remove the bearing is to drive the pin from the primary

Re: new guy - old 618
Thank you David. I thought I was missing something. I may try that. I've already tried holding the gear and giving little baby taps on the screw with a punch. And yes, I realized after I typed the

Re: new guy - old 618
It's supposed to be a very close hand fit, but some of mine are (were) quite tight and needed a light touch with abrasive paper not to stick. Suggest gentle prying with a screwdriver using the collar

Re: new guy - old 618
Thank you all. Can anyone who is familiar advise how the leadscrew drive gear is removed? It appears as though it should slide off, yet doesn't. there is a collar between the gear and the bearing,

Re: new guy - old 618
Yes, I believe on the 10" lathe, at least, it was an extra-cost option. Model numbers like TH42 would indicate Timken bearings, horizontal-tensioning countershaft and 42" bed. Without the T, it would

Re: new guy - old 618
Hi Don, A liberal application of either 10 or 20 beats the crap out of none! I like Mobil Vactra #2 for the ways. Dave

Re: new guy - old 618
I don't think any "modern" lathes use plain bearings anymore. Tapered roller or sometimes angular contact ball bearings are it. Various grades of both, ranging from reasonable price to you must be

Re: new guy - old 618
from what i read? the atlas came out with timkens first and sears wanted to keep the price down and stuck with bushings unless ordered with timkens... the 618 was prmarily a hobby lathe but also was

Re: new guy - old 618
You might take the table that shows the belt configuration. And associated speed and break that up into 3 groups (slow, med, fast). Use that as your guide.? But I didn't know this was required for

Re: new guy - old 618
The manual addresses speed with the sleeve bearings. It states that the clamping pressure should be reduced slightly for high speed and tightened back for slow speed. If it states what speed is high

Re: new guy - old 618
Jody, I think the Timkens were more like: we invented this newfangled thing called a bearing and we're now putting it into our lathes. ? ________________________________ Sent: Friday, January 25,

Re: new guy - old 618
Were the Timken brgs an option when they first showed up in Atlas Lathes?Sort of like a deluxe version. Mine is a Timken brg 101.07403, circa 1944.? Granted this is a 12"-Jody

Re: new guy - old 618
Interesting. I knew about the oil recommendation changing, I never knew they were putting timkens in them as early as 1937. I wonder now if the timkens were sold as a high speed option, or if they

Re: new guy - old 618
I've looked through a bunch of pdf's and a couple of original printed manuals. My original 1937 Atlas manual never mentions 618 or any other model number, as best I could tell, but it discusses both
