1940s or 50s Lathe
Apr 27th, 2017 at 6:47pm
 
Hello, I just purchased my first lathe from a woman who said it was her grandfathers.  It is a Craftsman, but it doesn't have any model markings on it.  I am trying to get it up and running but I can't seem to get the faceplate off.

Any ideas how I can remove the faceplate - or is this actually a backplate?

After I figure this part out, then I need to figure out how to replace the belt.  I am not sure how to get the spindle out of the headstock, but that is for another post...

Thanks for any help and ideas!

Here is a video of the entire lathe:

My first guess would be that it is screwed onto the spindle.  Can the indexing pin behind be used as a spindle lock without destroying it and the pulley?

No, I don't think so.  I think that is an oil cap for oiling the ball bearings (Just a guess though from reading through some old manuals).

There isn't a screw under the cap.  There is another one on the other side, but I can check again.

Good suggestion.  I didn't know what an index pin was and had to look it up.  I will try that.  I haven't been able to secure the spindle at the end to twist off the plate.

Be generous with penetrating fluid on the base of the faceplate first.  Pulley body and the indexing pin likely won't stand up to a lot of force.

Could you grab the outer edges of one of the smaller pulleys with a large pipe wrench?

The center area around the screw is raised, as if it might unscrew from the faceplate.  Might want to fuss with that first, in case somehow it locks the faceplate onto the spindle.  Doesn't seem likely, but . . .

Thank you Don.  I will pick up some penetrating fluid tomorrow and give that a try.  Is it best so spray it on?

I use PB Blaster with good success. Spray it on and let it set for 24 hours. Applying some heat to the hub of the faceplate can help also. Don't get it too hot !

What Dwight said of PB blaster and it is wonderful stuff..  On the back of the face plate is the whole thing screwed onto the head stock or does it have something a wrench can get ahold of?

Also can you somehow get to the shaft to keep it still?

Like you said the thing is an oil port and 30 weight should go in there.  It looks the  same as my old Delta lathe head with the oil port and they were nice.

I think someone already said about trying to remove the center screw from the faceplate first which might hold it on also.

Good luck and Welcome since I have not told you that before.

I would consider removing the spindle and then the step pulley.  Put the spindle in a vice and use a strap wrench to take off the face plate. 

Then remove the bronze bearings and press in new ones.  I found these as stock $2.00 bearings at my upscale local hardware store.  (I used this as an excuse to buy a hydraulic press),  but I am sure that ingenious use of clamps and dead blow hammers would work.

The bearing replacement was how I got my Dad's old Craftsman lathe ready to give to my nephew.

Where I worked long ago had pumps with 500 and 1000 HP pumps with bronze bearings and oil cups.  The old mechanic related that automatic transmission fluid was first developed in WW II as a replacement for sperm whale oil.  He mixed it equal parts with 40 or 50 weight motor oil (multi-viscosity oil would not do).  The pumps had thousands of hours on the bearings. 

Back checked his story, and a couple sources verified the gist of it. 

Have used heavy straight oil and ATF any time needed good lubricant and it works well.   A quart lasts forever.

ATF and acetone mixed 50/50 will work as a rust breaker/pB Blaster substitute with equal(IMHO) success.
