Just mototized my malt mill!

[SkiSoloII]

My father in law came up with a 1/6hp 1725rpm motor. I put my BC on a new board with an 8" pulley. Put a 1/2" pulley on the motor. Running about 107RPM. Crush looks great. Needed to support the board differently - the motor is HEAVY. I guess the next project is a cabinet.

Anyone got an old kitchen base cabinet?

I am a total homebrewing equipment junkie. Posts like these are not helping me avoid the siren song of going AG.

Motor shaft alone looks like 5/8" diameter a standard vs your "1/2" pulley" stated. I think you need to remeasure your ratios unless the grain mill pulley is 32" diameter by your photo to net 107.8 rpm's.

I'm pretty sure he's talking about radius there.

I'm pretty sure he's talking about radius there.

Even at 150% on the monitor I can measure 3/8" motor x 2" mill (horizontal /vertical average) equates to 5.33 to 1 ratio, 1725 divided by 5.33 equates to 324 rpm's. Not even close to the 107.8 rpm's posted off by factor of three times the ratio.
Over the years numerous mill builds posted with a 12" mill pulley 1 1/2" or 2" motor pulley with 216 or 288 mill rpm's, 6:1 to 8:1 ratio reductions.
Not to start a piss war, my eyes and mind must be fooling me these days.

My point is that 1/2" x 8" gives a 1:16 reduction. Take 1/16 and multiply by 1725 and you get 107.8125. Then take your screen measurements and throw them out because you have no idea what kind of scaling was done to the picture and it's a two dimensional image and basically he SAID what the wheel dimensions were and incompletesentencesandpoorgramardeserveagreatresponse.

To the OP: Good job on the build. I'm still powering mine with a drill. I'm looking forward to building mine up into a full blown milling station.

Nope. Shaft is 1/2" on the motor. 3/8" on the Barley Crusher. Look where the belt rides, not the OD of the metal on the pulley. I guess it could be a larger inner ratio. Said 1/2"X1/2" on the label. Won't be more than twice the speed. 214, eh? I'll live with that.

The drill I was using was burning out while trying to run it slow.

That's a pretty shiny setup. When I see nice stuff like that it gets added to my mental check list of how I'm going to upgrade things in that mystical "someday" I keep waiting for.

OK. Just measured everything by hand. Diameter of the small pulley is 3/4" on the inside of the belt. Diameter of the large pulley is 7" in the inside of the belt. Not exactly what I put in there to calculate in the first place, but....

Gives me a speed of 185RPM. I'm good to go!

Had to put nylon bushings on the BC shaft to mount the big pulley. Standard fare at the hardware store.

Root of sheave measuresments are not the V-belts contact or tacking areas unless a mismatch like using a A belt on B scheaves.
Reply of 185 rpm's is only off by 1.71 times your stated 107.8 rpm's, again you stated "I'm good to go!" that is all that matters.

yes, but was it an UNLADEN African swallow?

for now you can just add a few mor legs, and trim boards under the top (Look at a picture of a table and it's 'skirt' boards)

And very small rocks float.

What's the Vne of a unladen swallow and is is different with a ladened one having more stability due to added weight?
The CG shift must also be factored in also.
All tests performed with corrected barometric pressures, temps and humidity?
Standard field grain or boosted high energy altered gene grains?
Too many altering factors for the proper outcome.

Are you suggesting that coconuts migrate?
