Custom-sized toothed pulleys?
 

I posted a couple days ago that I was going to modify one of my machines with a belt-drive.
I've started in on that, and found that I'll need a toothed timing pulley... I figured I would. But, it does work, even with the rough temporary setup pictured.

Anyone know some place that can make a custom-sized pulley? I'll need them for the spindle shafts. I'm tempted to have a friend CAD them and just 3D print them... The bore on each is a bit different. 24mm and 24.5mm it looks like. 5.08mm tooth pitch.

have you looked here? McMaster-Carr

You can try Stock Drive Products too...they specialize in drive systems. You may need to have a shop bore out the pulleys to fit your specific shaft diameters, but that's a lot easier than making the entire pulley. Even if you had a pulley 3D printed, you'd have to make the bore undersize and then ream it to the exact diameter that's required. The bores would need to have only about .001" clearance (.025mm) for those diameter shafts...current 3D printing technology can't hold that kind of tolerance.

Yeah, I haven't found anything close to what I'm looking for. Anything with a 24mm inner bore size has a huge outer diameter, which I don't need. I need something fairly low-profile.

Rcooled, I'll check SDP, thanks.

Buy what you need and bore it out...or change the shaft size.

Kaman or applied industrial technologies can source it if exists, or have it made if it doesn't.

Found what I need, but we'll have to bore the center out to fit.

I picked up two of them locally, albeit in steel. I would have preferred aluminum
