We just finished building a Whizbang. Here are some tips from my experience:
First, buy the book. Kimball has it down, makes it easy, and why not make your life easier, too? If you build one of these, you are going to be spending a lot of time and some money doing it. The plans will help you spend both much more wisely. Don't re-invent this thing. It works just like he's got it. (I'm not invested in H. Kimball! I just appreciate what he's done, and his plan book is good.)
I am a 'scrounge' so I tried making this as cheap as I could. I made my own shaft from a a piece of 1-inch rod, and a 'spring shackle plate' I bought cheap at the farm supply store. It is for mounting springs on trailers. It is pre-drilled, thick steel and just exactly the right size. I am a fair welder, so this is something I can do. Not everybody can. If you can't weld, buy the shaft. I used plywood and plastic laminated for the feather plate. This saved me a ton of money and it works fine.
I used two straight sided USED plastic barrels because the bottom cut-out of the first barrel is not useable for the featherplate. Just about everything in bulk comes in plastic barrels now. You can find them cheap at barrel recyclers, craigs list, etc. (Under $5 or free.) I used one for the tub, and cut a 20 1/2 inch disc out of the side of the second barrel for the feather plate. The sides of these barrels are very reliably 3/16 thick. The rubber fingers fit fine in the side tub, and they work fine in the feather plate disc, too. I counter-sunk holes in a piece of 3/4 plywood to accommodate the back side of the fingers sticking out of the plastic disc, and laminated the two together with screws for strength and water resistance. It works great. Very cheap. The plywood does not ever stand in water, so it holds up fine.
Get a used motor from the pawn shops, junk stores etc. Used motors are free or under $10 if you 'scrounge around' a little. The featherplate is geared down so far that it doesn't take much horsepower to run it. Kimball says he originally used a 1/2 hp motor, and it worked fine. He later recommended a bigger motor because a bigger one didn't cost that much more - even though you don't need it. A TEFC farm motor is best, but any motor protected from water by the bucket would work, too. Think safety! The motor only runs a minute or two at most for each chicken, so it is not going to overheat!
I glued my frame together, in addition to the bolts. Glue in the joints really stiffens up the frame. Why not? You'll never regret it.
I put mine on 4 caster wheels so we can move it easily. It 'kicks' a little on start-up, but otherwise it works fine. You could 'chalk' the wheels with a wedge if it bothers you that the frame bumps when you turn it on....
I'm running about 215 rpm (2 X 16 @ 1725). Kimball says he would slow down his original speeds if he had it to do over. I see some really fast runners on youtube, and they work OK, too. I don't think rpm is really that critical.
I'm also hoping folks might want to rent this from me. I'm thinking 3 or 4 chickens a day might be a good rate. I'd rather have meat than cash for this. Who knows? I might stop raising chickens! Kidding - can't think of not having some chickens around the farm. They're fun, and we enjoy the efforts of their work!
