Help Needed: Lovejoy Spider Coupling
|
|
I went ahead and bought a Barley Crusher and the motor that everyone seems to like nowadays: https://www.surpluscenter.com/item.asp?catname=&item=5-1098
However, I need help with the spider coupling. Can someone provide links to exactly what I need to buy at McMaster-Carr? The rest of the items (mostly electrical) I am fine with. It's just the coupling that I'm not sure what to buy.
TIA for the help!
John

I used the parts below, except my gearmotor coupling is 5/8" whereas yours is 1/2". I had to lightly sand the barley crusher shaft for the 3/8" coupling to slip on.
6408K73 - Buna-n Spider For 1-23/64" Outside Diameter, Flexible Spider Shaft Coupling Hub
6408K123 - Flexible Spider Shaft Coupling Hub, 3/8" Bore, 1-23/64" Od, without Keyway
6408K712 - Flexible Spider Shaft Coupling Hub, 1/2" Bore, 1-23/64" Od, with Keyway

Thank you lamar.
So, just to be clear, do I want to order those parts for my purposes? Or do I require different sizes?
Sorry...I really am Spider-Stupid! 
Thanks for your help!

Yes, those should fit your shaft.
Sorry, couldn't resist.

Thanks for the help!

The shaft on that motor has a keyway. Why not use a keyed hub on it? Might as well take advantage of the keyway since it has one.

Lamarguy (or anyone else),
How do you like the motor listed? Does it have enough toque to not slow down when crushing wheat? My drill needs very slow feed of wheat in order to get through things on the Barley Crusher.
