Topic tags/keywords: lathe

My 25+ year Sears is on its last leg. The driver pulley is all bent out of shape and wobbles like a professional Arabian dancer hips in a cheap Moroccan’s cabaret. Upon removing it, it is all broken up on the inside and I can’t find the new part for it. Ebay has some for $45 used. I went online and was floored by the prices of new lathes that are 40+ inches. I don’t want to spend 3-4 G’s on a new lathe that size. Ebay has one new; never used one of what I have for about $300. HF has one for 299. HF reviews are mixed as to the quality, i.e., wobbles, cheap construction, too light, etc. I know how to weld, can HF lathe be reinforced with additional support to provide me with what I need without breaking my pocket? Should I go to a machine shop and have them make me a pulley? My experience has been that once one of old Craftsman’s parts start to fall apart, then other components follow to do the same thing. Any ideas?
Thanks in advance.
Mahdee

Get a new pulley.. doesn’t have to be ‘Craftsman’, just have the right diameter and shaft size. Give some more specs (model number, measurements?) and I bet someone will turn up a replacement much cheaper than the one you found.

Cheers,
Brad

When I’m looking for pulleys, bushings, bearings etc, I go to a local company called”transmission supplies” .

That’s theiir business…..check your yellow pages under “transmission supplies” as a category

OTOH lathes have come a long way in the lastt 25 years

Oh come on, 25 years, it’s barely out of puberty. My Craftsman is over half a century and still going strong.

Seriously though, you should be able to replace the pulley for not too much. Sears lathes were built mostly from off the shelf parts. But if you just want an excuse to buy a new lathe … well don’t let me stop you. ;)

Look in the phone book under motors or motor repair for an electric motor shop and take what you have to match up. Probably out the door for 10 or 15 dollars. If it’s a stepped pulley you may have to look online for a replacement.

If you just want new for news sake, you could probably just add a shelf to the HF lath and load it up with some sandbags.

Here are the pictures I took this morning. I was able to wrap a 1” wide copper sheet around the shaft and put the pulley back on and now it is not wobbling, but I know this is not going to last too long as the inside of the pullet has a lot of cracks. I definitely don’t buy another lathe if I don’t have to. The shaft is 1/2”.

Can’t really tell the step diameters, but a quick search turned up a lot of possibilities for $25 or less.. Amazon has some (new) for around $14 – 1/2” bore with 2, 2.5, 3.5 and 4” steps. The step diameters don’t need to be exact, just close.. a few hundred rpm one way or the other shouldn’t make much difference.

Cheers,
Brad

Buy a regular pulley and convert to variable speed with a DC motor.

Thanks MrUnix, Ricjk. I saw this one on e-bay today and it looks exactly like mine. As you can see on the third picture, the inside the pulley has these rectangular dents in which a “key” locks the pulley so the tip can be removed from the head stock. However, his description says: It has a 3/4” diameter bore mounts with set screw. I wonder if he is talking about the outside diameter? I’ll 1st contact him and 2nd remove mine and see if the serial numbers match. I think the price is reasonable unless shipping is $99.95!

A 3/4” bore pulley won’t work on your machine, and those indents are for indexing the workpiece (mainly for fluting with a router or similar). But it does give the step diameters (2, 2.5, 3.5 and 4”) which are identical to the ones I pointed to originally with the proper bore size.

Cheers,
Brad

mrjunx007…I know I will get grief for this, but I have turned on a HF lathe and they were a little less than impressive. Co-planar and vibration free they were not! Fix the craftsman even if it’s 45.00..

Thanks MRUnix. Thank you again will go with your suggestion. Moke, that is what I have read on the reviews as well. I am really hesitant to n=buy anything that has moving parts from HF although their nail guns have served me very well. Every electronically operated machine, belt sander, grinder, orbital sander I have bought from them has been a disaster. With that statement, we can share the grief :)
