I'm assuming this would be a direct drive project? Any ideas for couplings that would stand up?

or a 1:1 pulley system?

Correct, direct drive. Using a jaw coupling hub similar to what can be purchased at Grainger, and has been used by other members of this forum for their DIY grain mill projects.

I plan on attaching this motor to a Barley Crusher that I recently purchased. Still have to find a sturdy platform to install it on, and some other pieces of hardware.

One lovejoy the size of the motor shaft, one lovejoy the size of the mill shaft, one spider.

Sticking with the L50 sized Lovejoy's... looks like a 39 in-lb spider is the best you can do. Will that hold up on a barleycrusher?

After discussing with Grainger, ordered:

OP: Thanks for creating this thread. Using my Barley Crusher by hand or even with my portable drill is a PITA.

its available for me $115

not at check out "this item is no longer available sorry"

Hmm. I had one in my cart online but ended up doing the order via phone. I cleared the online order, then went back in and it is still available. I'm sitting in checkout and it still appears ready to go.

I wonder if it wasn't available because of that (not a great inventory system if so). Anyway, I cleared my cart if someone else wants to try again. (Can't use two of these .)

That's a decent motor. Not a bad price.

If you don't mind mounting in line with the drive shaft, this is pretty nice.

well, you don't HAVE to mount inline.
I'm using something like this from HD for $18-ish

Blast I missed it. Though I am sure my wife won't be disappointed... It says not available for inventory.

That's pretty neat too.

Do you think that is too much arse (torque) for a corona mill?

A question for you motor guys. Is there a way to find out torque on a motor if it isn't explicitly listed on the motor body?

I have a motor I use for my apple shredder that I was thinking about gearing down so I could use it on my corona mill. Here are the specs as listed (didn't see any gearing ratios):

1140 rpms
1/2 horse
7.8amp

I was given the motor, so I have no idea what it was from. It almost sounds like my dads old drill press motor (when it shuts off it has a sort of click and you can hear what sounds like a soft breaking mechanism).

I am not sure if it is well suited for grain, but hope it is because I only use the motor for a couple pressing sessions in the fall. Would be great to capitalize more us out of it.


I plan on trying to use it with pulleys and a V belt. Any recommendations for RPMs?

For apple grinding I use a 2.5 and a 9inch on the grind to get about 317 rpms by my calculations:

2.5'' / 9'' = .277: .277 x 1140rps = 316.66666

UPS delivered mine yesterday, it is a nice motor. It is also a beast, weighing in at 39lbs!
