JSP Maltmill DIY hopper and brewstand mount

[30Bones]

I got my JSP mill Friday and whipped out this simple mount out of some scrap 3/4" plywood. I had my Dad router the edges yesterday to minimize slivers, also rounded off the corners.

I didn't want a dedicated motorized stand and came up with a simple and space saving way to mount this to my brew stand to mill the grains and remove it for storage so it doesn't get burnt during brew days. This thing is massive so I may need to DIY a way to chute the grains to the bucket below.

1/4" x 20 SS bolts were used throughout (may need to upgrade the 2 on the stand, this thing is heavy). I drilled two holes in my stand and hard mounted 2 studs. The hole for the grain is 1.5". The rest is pretty self explanatory.

The hopper is an old 5 gallon bucket with the bottom cut out and riveted to a large funnel I already had. I clamp it to my keggle while in use.

Cool!

Question: Why don't you utilize the full width of those rollers when feeding in your grain?

Seems a waste of milling/ crushing surface.

How would one do that with my hopper design I can't say for certain, but I can only assume the grains disperse throughout the length of the rollers. I will try to take a better look next time I use it.

The creator and seller has this as one hopper idea. Eventually I may go motorized, but no real need to at this point.

The JSP mill only adjusts the gap on one side (at least that is the way mine is). So to get a consistent crush you can't use the entire width of the rollers.

No idea on that statement other than, yes the adjustable models only adjust at one side, not the entire length of the roller. My LHBS has a motorized one and man it rip through the grain and crushes perfectly.

Hmmm......Was just curious as to why all roller width, and no feed to the "full width".

Never seen this particular mill in person, and I am surprised when you say only it only adjusts at one end.

Feel free to read his site, I am no expert on this topic. I bought a mill based on some research, word of mouth, price, made in the USA and lifetime warranty.

Good read!

The pic he has posted, ( with the full width hopper), is the configuration I was referring to for most mills I have seen.

Same here. I will go that route if/when I decide to motorize it.

Well, my Dad made me a 2'x3' table I will be getting on Chritsmas. I have the pulleys/sheaves purchased and a coworker gave me an old 1/2hp motor I have since cleaned up and painted.

Sheaves are 12" and 2". Belt will be purchased once I have it all painted and mounted. I'll have roughly $60 into this, a bit more once I install a dedicated electric box/switch.

Well Dad and I cut a hole for the mill and mounted the motor Christmas Day and I brewed the following day. Worked like a charm and chewed up 14# of grain nicely. Not too fast and a good crush as usual with my JSP.

Changes in order already:
Dad made the table with a 2" lip all the way around. The way we mounted the mill I could not cut the hole for the mill the full 10" width with the 1x4 skirt support in the way. It worked, but not optimal. What we should have done (and I will be doing this week) is moved the mill and motor more into the center of the table, cut a "slit" for the belt and pulley to go. This would allow a hole for the entire roller width and room to install a chute to channel the grains into a bucket. I will need to cut another piece of plywood to make it look good, but that's not a big deal. I will rough it out on this one and if it's where I want it, transfer it to a new sheet of 1/2".

All in all I am into this for a total of $235 roughly.
1/3 or 1/2hp motor. I can't tell, the tag is beat up and it's OOOOLLLLD, but it was FREE from a coworker. $Zero
JSP maltmill, barebone model, adjustable. $175 shipped IIRC
12" sheave $39.05
2" sheave $7.45
1/2" to 3/8" reducer (3 pack) $7.95
60" belt (local hardware store had them on clearance for $3.50

Officially done minus paint. Going to add some holes for my hop addition cups to sit recessed also. I'm happy with it.
