Making a Pulley?

[Uglydog]

Made some bolts with special heads to hold the head on my Cincy as two were broken, and the Gib Screw.
Wiring again next Saturday!

I didn't see any noticeable wear on the gears within the headstock. There is likely a way to measure for excessive wear. However, the spindle doesn't seem sloppy.
Regardless, the V-Belt pulleys each have large chips in them. I'm considering TIGing them and turning them. But might be easier just to make new!
I just watched the Tubalcain videos on making pulleys. I figure I can make them, once I get them off the spindles. It's been suggested I bake them at 400F as it someone likely used locktite.

My larger concern is the Gilmer pulley the smaller shows what I believe might be judged as significant wear, but more importantly there is about 1/8" of slop on the shaft.
Does anyone know of a video or "how to" for making a gear with teeth such as a Gilmer? The other 3 Gilmers seem to be in adequate condition.
I've got a Grizzly 6" vertical & horizontalrotarytable withdividing plates and a tailstock (http://cdn0.grizzly.com/manuals/h7527_m.pdf), and I still have my Rong Fu 30. However, I'm not sure how to do the calculations, do set up, use the dividing plates, choose and end mill.
I figure like everything else, by the time I make the sixth one it'll be close enough to work.

I accept criticism well. If a Gilmer is above my pay-grade please say so.

Thank you,

You'll never succeed unless you try and like the old saying, "if at first you don't succeed, try, try again"!

Good Luck!

I had a new foreman in one shop, I worked in, walked up to a lathe that was turned off and grabed the chuck and put the spindle in low gear. He said if he could turn the chuck with not nuch effort then there was a lot of wear in the drive train. He was the only one I knew who did that.

Good luck in your repairing your lathe.

If it was me I'd be repairing your pulleys as you have suggested rather than make new ones. Unless of course you want ot make them for the exercise of doing it.
To repair, tig up as you have said and then mount them on a mandrel and machine the repaired area. Would be a lot quicker ( and cheaper if you have to buy the metal) than making a complete pulley.
