new mill completed
you have certainly done a very nice job , I use a roller / drill rig, my cash outlay including a custom hopper (large funnel) was $100 mill, $50 drill, $3 funnel. now I can crush 15# of grain in about 4 min's.
What was you final cost of construction? Not counting other failed tries, just your working prototype.
Bought the crankenstien 2a mill "basic" and the 1/2" adapter

Bought 2 of these Motor's of ebay ...."spares are nice 
110v, gear reduction, final ratio of 58 rpm...
I suggest if looking for a motor, find one "gear reduction" "with capacitor" with atleast 110 inch pounds of torque...and atleast 100 rpm output... Problem i had Initially was trying to run a 4-1 ratio so i could get the mill spinning around 250 rpm, problem the motor I got would stall out...only about 25 inch pounds torque... Downsized the driven
too a 2-1 ratio, shortened the belt 5" and got an output @ the mill @ 120 rpm and good torque...Hopper holds 11 lbs, and run's it through in about 4 minuites....With a constant crush....
You could use any motor, but you would have to add a pulley so large at the mill to reduce the speed, which doesn't make it compact.... which i wanted....
1/4" Plexy-glass was free..."friend owns a glass shop, and these were cutoff's"
Other pieces bought from Lowes.. "just moved in up here" great selection of gadgets
Mill $88
1/2 adapter $10
Motor $20
2 pulley's $12
Belt $5
Plexy adhesive and needles $15
s/s fastner's $8
Idler bearing $3
Light switch and pvc box $had
Plastic grain box $13
Misc $20
As for design, I just went for it,
Base is 16x16, 2x4 hole cut into it for feed too the mill, mill mounted to the base with 5/16" s/s machine screws, Hoper is of 7 different pieces glued together, than secured with 1/2" s/s screws for additional strenght....I added an additional support bearing to the driven shaft of the mill, so the force of the belt tension
would not prematurly wear out the brass bearing on the mill....I would recommend doing the same.....
As for the motor mounting and tensioner.... That took some thinking .....
Made up a aluminum mounting plate for the motor, than attached that to a piece of 1/4" plexy...The pivot for it is from hinges off an old stereo cabnet "the ones that hold the glass door in place " Just mounted them too the base, slide the plexy into where the glass would go....walla hinged...As for the tensionor..Just drilled a hole through it and the base piece and ran a bolt up through....tighten nut as required....
Added a simple light switch for on/off power......
If anyone wants closer up pics of the pieces / or actual dimensions....let me know ????
They do sell the base and hopper ready for it, but is made of wood...$35..... But I wanted something water proof.....
Maybe cost me a bit more for the final product, but have what I wanted in the end... Little better..little improved.....
Where did you see the base and hopper for $35? Your design is great!
