drill press pulley-HELP!

[stoveboltgunnut]

I am looking for a replacement pulley for a drill press I was given. It is a Craftsman 15.5 inch floor model. It is in great shape, new chuck, tight bearings, but the spindle pulley is shot! looks like it was ran with a loose set screw. It wobbles around on the spindle. I need to find a replacement, but cannot locate one. The original is a Browning SCZ3, variable speed step pulley.

Sears lists the pulley as NLA, and google located browning, but cannot find a place to buy the thing! I have checked McMaster-Carr, but they do not list one that would work. I don't think there would be enough material to bore it for a sleeve.

Any ideas?

Here is the press:

Eprey is going to be your best shot; Find one someone is parting out...

Post a Pic of the pulley center, another option might be to sleeve the thing, depending on how its constructed, That it is the spindle pulley complicates things...

Outlaw, thanks for the help! I just don't think that it can be sleeved, but I will post pics. Do you think that this one would work? It has a keyway, but it also has a set screw...I don't need the keyway.

I do not believe that is the right one for your press. I believe the original has move grooves and they are smaller. If I remember right the belt is tiny also. Dad has one I believe came from Montgomery Ward, under another brand. It should look more like the pulley pic on the front of your press.

you may be right, but it is the correct dimensions, and I believe the right configuration. the plate on the front shows both the motor and spindle pulleys, with one being shown above the other. The manual shows the pulley I have.

It depends on the CL to CL spacing of the pulleys; DP's often use a tighter spacing than off the shelf pulleys.

I'm surprised that your pulley uses the 4L belts; all the other DP's of that type I've seen used an ultra thin belt with 8 sheave pulleys.

So the spindle drive on your DP uses a std pulley and setscrews? Can you post a pic of the hub? If so you are lucky; usually the pulley has the splines or a cast in hub which makes them orphans real quick!

Is the hub a std shaft size?

Isn't the spindle pulley usually splined so the spindle can move up and down and still spin?

I know the exact DP you are talking about I just re-furbed one for a friend that used that 8 sheave pulley setup. decent DP and useable for both metal and wood...

Usually; but this one may have a separate splined hub...

 

[stoveboltgunnut]

It is a standard 1 inch bore. here is the spindle hub, no splines. It has a flat milled in for the set screw about an inch from the top:

here is the motor pulley, maybe it will help:

not on this one, the splined shaft rides inside of the spindle.

That one on Eprey may work. Looking at the pulley spacing both appear to have close to a knife edge. If yours are 4L (1/2") belts, and the pulley diameters are the same (Or a bit larger on the new pulley; that will allow you to go slower, you DON'T want faster...), and the center hole is a fit, then you should be OK.

Actually the splined center shaft is the spindle; the hub the pulley goes on is "floating" on the spindle shaft and is supported by its own bearing in the head casting. Unusual design, but I like it as you don't have an orphan pulley as a drive pulley

Thank you VERY much for the advice!!!
