Default Upfitting the "Wondermill"

We've had a grain mill for years used it a few times and sort of like making Firewood manufacturing our own flour takes more grunt than it first appeared. Aww, hell you just turn the crank uh huh you do it for awhile. Current events have spurred me to mechanize this chore just in case. Initially I thought this might be the perfect use for the motor I canniballized out of the daughters stand mixer she stripped the gears on. Could I make it work? Yes, but, lacking a means to machine a shaft adaptor. It would have required $70 in parts to build a Jackshaft assembly to go from XL toothed belts to driving an pinion gear for the factory conversion. I remembered I had something in the "Resource Pile" as Chris refers to it. That might be perfect once the "Inventory Manager" located it that took a day once I recalled where it might be. It was sucessfully located and tested for function Etc. It felt a little stiff like the oil was gummy. Did a cleanup and oiled her up with the Kroil light machine oil Ron recommended for weapons and whatnot (I pay fucking attention when Shade makes recommendations). The gearset was supposed to be here today ETA is looking like tomorrow now. In the meantime I've been making a switchbox and other odds and ends to go with the resource treasure. 1/4 Horse Century built in the US of A motor with oil caps on it I'm guessing 60s- early 70's maybe smooth as silk can barely hear it run

The gear set showed up and I have things mocked up. I counted gear teeth and determined the reduction ratio. I came up with 8:1 so this motor runs at 1725 RPM which puts the mill speed at 215 RPM. They recommend no higher than 300 RPM so this should be about perfect fast but not too fast Now I have to head to "Trashmart" AKA the transfer station to see if I can score a piece of plywood to mount the whole works on. I also need to pick up some real set screws to lock on the gears. I'm not impressed with what was supplied with them. Cap screws with a jam nut threaded on them.

Having a flour mill would be handy for mixed grain bread and muffins.

I have a set of stones for it and steel milling burrs that I can even make peanut butter with.

So, I got it assembled on a mounting board wired etc set to jet NOPE. The motor rotation has to be reversed. Okay, no biggie just switch 2 wires. Except one wire is too short to be attached to the other terminal. Which I established after fighting with it for 40 minutes or so. Totally burned up my supply of patience for today. Will splice an extension on it tomorrow and pray I didn't fuck up the Old School cloth insulation too much.

What a PITA reversing the motor rotation turned into. This morning I tried just adding to the short wire by joining an extension on it with a ring connector and some heat shrink tube to insulate it. No Bueno things got too crowded and it just wasn't gonna fly. Then I noticed some damaged insulation on the other wire. So much for a "Quick & Dirty" fix. Pulled the motor off tore it down and proceeded to solder and shrink wrap extensions to the motor wires. That was fun let's just say I wasn't at the top of my game after a few beers Saturday night and a quart cup of coffee to get me going. Soldering and hands shaking bad enough to thread the needle on a running sewing machine are not conducive to top notch work. I got them done and shrink wrapped. Reassembled the motor and gear drive wired her up and tested for function. Success finished it up tonight after a trip to the valley. Then ground up a couple Lbs of wheat for a test. Won't run it any more until the lube comes from McMaster Carr. I need to settle on a design for the guard and get it built.

Was going to seal the plywood everything is mounted on. I scored a full gallon of Minwax Poly from "Trashmart" got things sanded and masked off with painters tape. Never got much above 40 today and the humidity is too high for applying anything oil-based. I found material in the Resource pile to build a guard. Did a little CAD (Cardboard Aided Design) work last night. I think I have come up with a workable plan. Probably try to get everything cut tomorrow.

I was thinking that if you couldn't reverse the motor a couple of sprockets and a roller chain would give you similar reduction and solve the rotation issue.
But you got it done

The sun returned today and it warmed up enough to get 2 coats of Minwax Poly on the base board so I can get the guard and whatnot mounted. Plan at this juncture is to get the parts cut to build the guard tomorrow. Still debating on whether or not to paint the guard obnoxious "Safety Yellow"
