Grain Mill Page - Motorized JSP Maltmill
A three part series where we brew a 20 gallon batch of Denny's Rye IPA.
08-Oct-2006 - Today I retired my Corona grain mill and replaced it with a JSP Malt Mill. I picked it up from a friend at work who didn't have time to brew anymore. Cost was $40 plus a 12-pack of Oktoberfest. I built the extra large capacity hopper with the idea coming from a fella named Stirplate on Northern Brewer's forum. The knurled rollers are 10" long and really make a nice crush and power through a 40 lb grain bill in no time. I bought a 1.5" pulley with 5/8" bore, a 10" pulley with a 3/4" bore, a 1/2" X 3/4" bushing and a 40" Type 3L V-belt all from Graingers for about $23 total. The rest of the stuff you see is all leftover scraps of lumber and electrical stuff from various odd jobs. The pulley ratio gives a grain mill speed of about 194RPM. Here are the pictures:

23-July-2006 - I got tired of making 5 gallon batches so I set out to upsize my brew system. I bought a 25 gallon SS megapot from Austin Homebrew for $199 and free shipping and bought a March 809-HS mag drive pump for the wort transfer. I had a friend model up the concept for the new brew cart on Pro Engineer. Then he borrowed a MIG welder and we spent the better part of a day welding and fabricating all the pieces. Then when I got it home, I spent a few more hours putting the finishing touches on it. I took great care to keep all the brewing equipment on the cart and ready for use.
Now I can get 4 times the amount of beer from the same brew session with less work. No more heavy lifting of hot liquids.
9-11-2008 I'll give you all the details about my brewcart and with a little tweaking, you can make one to suit your needs. I bought my steel at Home Depot. Probably could have been cheaper if I went to a steel company. The steel for mine is all 1.5" X 1.5" X 1/8" thick angle iron. I made the inside opening for the Superb burner to drop in exactly 11.75" X 11.75" and the burner fits in real nice. Here are some of the other dimensions measured from the bottom of the stand (base) where applicable:
overall length 64"; overall width 15"; overall height 48"; ground to base 4"; base to BK surface 10"; base to MLT surface 30"; base to HLT surface 48"; length of BK surface 20"; length of MLT surface 29"; length of HLT surface 15"
I changed a few things after making the stand and using it a few times. One thing was the wheels. I removed the two wheels under the HLT and the two adjustable pegs under the BK. I replaced them with heavy duty locking swivel casters. They were $15.12 each from McMaster Carr. Much better maneuverability. (4) Swivel Casters McMaster Carr p/n 87845T172 DUAL-WHEEL THREADED-STEM CASTER, W/BRAKE,3" X 1" RUBBER WHEEL,1/2"-13 STEM,250#CAPACITY I also recommend a waterproof top where the MLT goes. I started with wood paneling but eventually replaced it with a thick piece of acrylic. Put as many hooks and things onto the brewcart as you think you will need. I also hate always trying to figure out how much strike water I need in the MLT so I made a SS ruler with the marks showing corresponding pounds of grain. Then I fill up my MLT until the depth is equal to the total weight of the grain bill. Same concept for another ruler to measure the volume of wort in the BK.
