Restoring Drill Press : Sourcing Splined Coupling

HI PM

I'm in the middle of restoring a Toolkraft drill press (8in, 1/2HP, model 360A).

Unfortunately, I broke some parts on disassembly, and I'm looking to make or find replacements.

Specifically, there is a sleeve at the top of the press that was stuck to the upper pulley, so I cut it out. It is shown next to the glove in the pictures, and the male piece of the spindle that rides vertically is shown in the other picture.

- Exterior of the sleeve is 3/4OD and rounded (fixed with set screw to the pulley).
- Interior of the sleeve is 5/8ID, but is fluted with 5 longitudinal channels / aka 6 teeth, which the top of the spindle rides in.

I've seen very similar channels on other drill presses, but wondering if this is a generic part? I've found keywords "splined coupling" and "splined sleeve", but haven't found a source yet.

Welcome your suggestions!

You really screwed the pooch here,most likely that sleeve was not designed to be removed from the pulley. You have 2 choices here as I see it make a replacement of scrap that drill press. That cheap home owner grade machine is not worth much effort or expense to repair. And by the way please read the stickies about what type/kind of machines that are not allowed on this forum. Now a question on how to make that sleeve without mentioning the machine will be welcome.

They do exist but these are much larger OD.

Every splined shaft I've seen available commercially is usually 1.25" OD or larger.

You would think some one like "flaming river" would have something.

so from the (lousy) pictures, it really does appear that the female spline has 5 "channels", while the male has 6...

Seeing as this is probably a POS Chinese drill press, this thread is locked.
