My pulley broke on my Delta 46-111 lathe

Wondering if anyone has had this happen or heard of it happening? I was turning a piece on my old Delta lathe and heard a very different noise. The lathe began to spin to a stop while I heard the motor still running so I shut down immediately. I noticed that the innermost rim (closest to the motor)of the 4 step pulley had separated from the rest of the pulley and was spinning to a stop around the motor shaft and the v-belt had slipped off the pulley.
I bought the lathe a few months ago, am new to the craft, and hadn't noticed any misalignment in my brief visual checks. I'm getting by in the mean time by running at the 3 higher speeds. Now I guess I need to either repair the pulley or buy a new one, don't even know if it can be welded back on? Any thoughts on a repair strategy, parts for this model don't seem to be readily available and when they are they cost an arm and a leg. With the way the economy is going, I don't want to spend what I won't have tomorrow...

Can't repair a zinc casting. You're in for a replacement. May not be a thrill, given the size of the shaft. Get on the horn to Delta and see what's up.

It may have nothing to do with you, of course. Used lathes bring their history with them. I had to file my long toolrest because the previous owner was an underhand man and had chewed it up in a few places. It's been with me for five times longer, and probably three-four hundred pieces more with no recurrence. I'd go to owwm.com and see if anyone has parts. Wasn't exactly the top of the line when it was current, so there may not be many out there.
 
Rick I don't know were you are located or your local resources, but you might take the broke one off and take it to bearing house or a repair center that repairs wood working tools and they might have one( off of a drill press and have it bored to fit the shaft) that would work if it is close to the size it should work as long as the shaft size is the same. I don't think I would spend the money to get it welded, one depends on the material that it is made of and two if they did not true it it could cause some vibration problems.One other thought that might work is go to the hardware store and pick a single pulley the size of the one that broke and slide it up next to the good ones and lock it down. you might have to smooth the jagged edges up with a file but should not take much. good luck
 
Try This!

Did you go done to your local Ace Hardware. They might have a replacement, or can get you one. Or look up the local Dewalt/Delta tool repair shop, the might be able to get you a new one.

I just bought an old Delta 14" bandsaw, and the had a part I need for it in stock, after a little searching.
 
Hey, Rick, welcome to the forum. Step pulleys are readily available from a wide range of suppliers and, even though you may have to make some adjustments (sleeves, shims, etc.) you should be able to get your machine back into working order without too much trouble. If you can't find a OEM part, mic up your pulley shafts and try source like WW Grainger, Aubuchon Hardware, Clesco, etc.
 
step pulleys

One of the best sources I have seen is Wholesale tools. They have three and four steps and bores going up to one inch.

If everything else fails, turn a new pulley in wood. The end flanges should be thicker than original, to compensate for weaker material, if there's enough real estate available. This could also be your introduction to segmented build-up, because you'll need to embed T-nuts to receive set screws for clamping it to the shaft.

Delta Pulley

Rick,
I have a complete 12' Delta headstock, including the pulley cover, for sale for $50 plus shipping. The pulley looks like it's in good shape with no cracks, bends or breaks. If you're interested, contact me at tcarter771@bellsouth.net.

You could also check eBay, using 4 step pulley as the search words. There usually are a number of pulleys available.
