Hello All,

I'm plugging away at my Kaa-2 install. I tested my auger today. It fills a 5 gallon bucket in about a minute. It's an oddball 5" tube grain auger.

I'll attach some pics. The gear box is a 50-1 ratio. With the pulleys used, I figure it's turning the auger apx 30 rpm. I can always change the speed with pulley swaps, but it seems ok. The auger shaft is just .065" wall 1" tubing and no keyway. A machinist friend made me an alum plug to fit several inches into the tubing and I used a heavy duty ebay bushing bore pulley [tapered, split bushing tightens on shaft]. It seems to be holding ok so far.

The motor mount pivots on the wall mounted brackets, and the weight of the 1/2 horse motor pulls tension on the motor to gear box belt. Btw, the machinist made the threaded pivot lugs [from s/s bar stock] that I welded to the motor mounting plate. I needed s/s, since the motor mounting plate is s/s [I hate to paint]. There would be other ways to make a pivot point too. Even a nut welded on would work fine imo.

Belt tension can be varied by different length belts. A longer belt will allow the motor to swing down providing less weight and therefore, tension. The speed reduction box is a "Winsmith" 920 that a friend had stashed. Btw, such boxes are plentiful on ebay, although most are direct mount to a motor.

Further plans are to fashion a latched, gasketed top for the hopper with a 6" inlet, and heavy wall clear plastic flex hose between auger outlet and the hopper lid. I'll fashion some sort of gasket for the hopper to stoker inlet junction too. I'm aiming for no dust.

With saving bandwidth here in kind, there are pics of the mount that holds the bottom of the auger tube in this thread: COAL BIN Pics See p 39 and 40

Fwiw, with a 7" pulley on the auger, I could turn it by hand and fill a bucket as fast as the motor. My point is, imo, a person could actually use a large wheel and handle on such an auger and spin it be hand.

Back to boiler plumbing and wiring....

Dave

Very nice work! At only 30 or so RPM, it should last a long time. I think they normaly turn about 300 rpm or so.

Thanks, Gents,

I'm a sheet metal worker by trade [big duct jobs and heavy industrial work]. I have some equipment at home, and access to bigger equipment, material and such for this type work. Now plumbing or electrical is another story. I plod along.

A buddy stopped by and I tested again. 48 seconds to fill a 5 gallon bucket with current pulleys.

The auger came with a 1 horse motor, and a 3" on it and 7" on the auger shaft. 4/7 = .428 x 1725 = 739 rpm!

Dave,

Nice work :!: My goal is an auger system out of my bin also- but not this year. I just need to get my system running. Interesting comment about a hand crank. I'm just that cheap to try something like that! :lol:

snowman,

Thanks for the kind words. My metal working trade has served me well. Esp on car/truck hobbies and home type work. I always try to learn from persons in the other crafts too [if I could just master soft soldering LOL]. I post the info and pics so that others might get ideas for their project. I try to give a little back here, as I sure have taken a bunch away.

Steve,

A hand crank might give you a work-out if you have a big hopper, but I really think it would do ok. A person could always add a motor drive later.

Dave and others I am very interesed in a coal auger setup. How are the augers working what are the pros and cons. I need about 10 feet and the auger tube would be full all the time so I'm concerned with it binding up. Any info would be appreciated. Brian

Brian, these augers would move 3/4 stone with the gear reduction they have. Coal is very slippery, so don't worry about the auger starting up when full. It is a non issue. I've used them for over 25 years and they still have no signs of wear.

The elusive ash auger is still the stumbling block.....but not for much longer. :!: :idea:

Dave, Excellent Job with the install. Great Craftsmanship in difficult quarters. The auger is damned heavy with the motor on it, without a lot of help.

Thanks for the reply. Is Daves unit over kill, under kill. Tell me what you think the perfect auger would look like. 6 inch or 4 inch, gear reduction, what size motor and pulleys. Like I say I need to move my Buckwheat about 10 feet. Thanks Brian

Here's my bin to hopper auger. It's from Washburns Farm supply. Here's a link.

It is about 10' to the hopper moving rice coal. This was the first season for it. I could not be more pleased. Just a flip of the switch and it loads the 250# hopper in less than a minute.

@Dave,

Very nice work. I am rebuilding my bin that I use an auger for trying to get it from the basement to the outside wall. Judging by the angle of your auger I was wondering if the bin is completely above ground or is this an inside wall that keeps the bin separated? I am thinking about digging down about 3 feet on the outside of my foundation to put the base of my bin to accommodate the angle I will need on my auger which leaves me with 2 quick questions hopefully someone can answer. 1. Can I use a metal cover on the inside of my bin (plywood) to help the coal slide better without worrying about corrosion and if so what should I use? 2. Being that I wanted to create a "funnel" to focus the coal down to the auger feed I was planning on using stone as the support under the plywood slants for support. If I do this would I still need to pour a foundation of cement or would the stone be enough since it's sitting on earth?

I am sketching things up so I don't have any pictures to post yet. I'm just trying to determine if this will work so I know if I can proceed with the outdoor plan or stick to the inside bin.

Thanks in advance for any help and experience anyone can offer.

I have a line on a 4 inch auger to move my buckwheat coal is there any reason it won't work?. Brian

Techclique,


Sorry, I haven't been here for a while. Thanks for the kind words.

< I was wondering if the bin is completely above ground or is this an inside wall that keeps the bin separated?

My house has a sloped lot, bin is seperate room, block wall seperating it from boiler room [both are under 1st floor garage slab]. the bin floor is same as basement floor level, top of chute is at 1st floor level on side of house.

> . Can I use a metal cover on the inside of my bin (plywood) to help the coal slide better without worrying about corrosion and if so what should I use? 2.

Imo, normal galvanized sheet should last a good long time, and would allow coal to flow much better than plywood. I might use treated plywood, esp if you use stone for a base for it. Moisture level in ground would effect life of both to a large degree, imo.

Fwiw, imo, slower is better. some say run the auger fast, and let it 'fluff" the coal, but imo, that would make for more grinding of the coal. My auger is slow, works for me. Fills a 5 gallon bucket in apx 1 minute.

Pic below showing layout during install. Chute bottom is about as high as the auger gear box. Bin is apx 8' x 8'. Much shovelling needed to get that 6.4 tons in there. With empty bin, about 2.5-3 tons is all that'll roll in. Then, you can shove about another ton or so in with a long shovel. Then I have to get in with the coal and shovel it back. Once it's in there, it's cake though.

--

whistlenut,

The gear box isn't very heavy, i made brackets to mount it where the motor fit originally. The motor hangs on a hing affair on the wall and the motor's weight keeps tension on the belt. Tension can be adjusted via shorter or longer belt. Just keep your hair out of the belt!!

I haven't posted pics [will], but I made a cover for the hopper that has a 6" snout looking up. There is a short piece of 6" rubber flex hose from the hopper outlet to bin cover. Foam rubber gasket on hopper lid, and latches hold it tight. No dust at all. Unless your coal is damp, you WILL get dust of you let it free fall into the hopper from the auger outlet.
