Recently, my delta planer went on the fritz. I bought the new pulley and drive belt, but the pulley did not come with a keyway. Barely able to make sawdust, I am certainly not a machinist. I know keyways are usually available at hardware stores, but how do I know the correct size?

I’m sure you geniuses will have an answer for me

Key stock comes in standard sizes 1/8, 3/16, 1/4”, I can’t see it being any larger than that, for that size shaft, but don’t guess use a caliper and measure it. The Delta uses a housed key which means you can’t just slip it on, you will need to cut it the right length and then grind or file the ends round to fit in the milled key slot, then you can slide the pulley on. Here’s what it should look like, and if you prefer to buy, E-Replacement Parts .Com has them in stock.

Dang, I wish that was shown in the schematic. Well, I’ll take a stab at filing one and if that doesn’t work, I’ll order it. Thanks for the education, just never know all that you don’t know.

Nothing magical about keyed shafts.
Key stock is available from Ace or True Value hardware in both English and metric sizes in the Hillman parts boxes.
Measure slot, or take the pulley to store and find one that fits.
They are soft metal that cuts/files easily.
Use 2 short ones if that is all you find.

The pulley on my 22-580 destructed a few years back. I really liked the planer, but I never could get it working right again. Gave it away and got a Dewalt 735. I hope you have better luck than I did.

To all,
Here is the latest and likely last post about my trusty old Delta: after getting the new belt and pulley, I pulled everything apart and discovered the spindle had huge chunks missing. I can only guess that awful noise I heard coming from the machine was pieces of the spindle being eaten by the pulley demons. I plan to give her a proper burial.
Today, I was offered an unused Dewalt and may have to make the switch.
Thanks for everyone’s great solutions. This forum has never let me down and I truly appreciate all of it.
