Looking for step pulleys

[Mike Cunningham]

I'm restoring an old Rockwell/Delta, as part of the process I'm installing a DC motor and controller. I'm in need of a couple of 4 step pulleys. Does anyone have a source.
Thanks,
Mike

Unfortunately all 7 are out of stock. I'll send an email to them.

Mike:

Keep an eye on eBay - search for "lathe parts", "lathe delta", etc. and even on the model number of the lathe you are restoring. There are always people parting-out old lathes and other machinery, and in many cases sell these items individually instead of a "fixer-upper" lathe that they can't guarantee performance. Make sure the seller is reputable (good feedback score), and ask questions, particularly regarding whether there is any damage to the shaft hole, keyway, and set screw areas, and that the pulley is 'true' without bends or distortion. I'm guessing you'll find at least one or two auctions for what you need in a period of 3-4 weeks....

Good hunting.....

If it is the motor pulley and not the headshaft pulley, I was able to get a replacement from Grainger.com. The steps are a little different but it has worked fine. The slow speed will be a little slower and the fast will be much faster.
You might have a store near you. If you order online, you will need a business license.
Hope this helps.

Finding an exact match may be difficult. Rob's advice may be your best answer.

I have an antique Delta (1929). It has a non-standard shaft diameter, as well as weird belt spacings. In such a situation, it would be well-nigh impossible to find a replacement. If you have access to another lathe, and if you're just trying to restore function (i.e. not a historical restoration), you can make your own pulleys. Make a segmented buildup with t-nuts embedded to receive setscrews. The groove profiles are available in Machinery's Handbook. Oak is a good material for such pulleys.

I have found that wholesale tool has a good supply. www.wwtool.com
Their printed catalog has a good description while the internet has you open up each stock number to get a description.

Look for "MASKA Pulleys" with your search engine. MASKA has cast iron pulleys and has them up to 1 1/8" bore. they may cost double the price of aluminum pulleys from BROWNING (get these from your loca Power Transmission products dealer) but are better suited to Lathe applications.

I think the Delta headstock pulley may be larger bore than 1 1/8" but I have never measured one.
