Granary repair

I was given an old granary this year. It was from a very old combine and had been converted to hold grain for chickens. It had not been used in a very long time and the entire bottom had rusted out. It still had the old pto motor for an auger on the front. It was trashed but it was still there. I have finally gotten around to repairing it. The problem is I have never really attempted a metal project this big before. My one quarter at BMCC with the welding class to learn stick welding did not cover this. Especially since the Gingerman changed the welder to a wire feed system. I have been trying to teach myself to wire weld. It is not quite the same as stick welding.

I have spent a couple weekends cutting out the bottom with a disc cutting wheel on my DeWalt 60v grinder. I have accepted that to work with metal I do actually need to wear some protective gear. I am wearing long pants, long sleeve shirt, leather gloves and eye goggles when I grind or cut anything. I switch out the goggles with a welding helmet and welding gloves when I use the welder. I get popped on the arm or face every once in a while but the important stuff is protected. I needed to buy some sheet metal and when I went to Packy’s the only type they carry is 14 g. I do not have a sheet metal brake. I needed to bend an angle into the sheet metal, both sides. I cut the piece then tried to bend it with a hammer and some clamps. No go. So I then tried to bend it over a piece of angle iron with one piece under and over the bend and beat on it with a heavy hammer. No go. So then I ground. Groove on the bend line and tried again. No go. I then proceeded to cut two inch grooves along the crease line about every six inches, so I cut out about 25% of the material along the bend. I then put it in place, welded one side down and then started to beat on it with a hammer, jump on it and used the forks on the tractor to bend it to my will!! I still ended up with 1/4” air gap in a few places that was painful to fill in with the wire welder. It would have gone faster if I had used the stick welder. But who wants to do the conversion again and then convert it back? I am too lazy for that much swapping around.

I was able to get the first half welded on and welded the gate holder in place. I marked the drill holes for the gate but I think they are wrong. One side looks good but the other looks like I let it slip while I was marking holes. I will just drill one hole. Put the gate on, mark and drill a second hole, insert bolt then I can get the other four in the correct spot. It will most likely be the very last thing I attach and I am going to bolt it on instead of weld it on. I bought a grain gate just for this purpose.

A full sheet of 14 g sheet metal cost roughly $110. So I think I can make it all with this one full sheet, if I piece the other side together. It will be close. I want a second granary, five feet on each side and five feet high. I have been looking to see if there is one out there available. The reason I want that size is I can fill it with the bucket of my tractor. If I get a real tall one I will have to use a grain auger. At this point I may have all the structural material in scrap and would only need maybe 2 pieces of angle iron for the lid and all of the sheet metal. Each side could be done with a full sheet of sheet metal, I would need one for the bottom and one for the top, six full sheets plus the grain door and it would cost $700 in materials, plus $100 in welding wire. I am thinking that this is the way to go to get a second one. An old water tank would be the bomb! I may keep looking, if I mounted the tank on a downhill angle I could just put the gate on the low side, a fill lid on the high side and I would be set!

My welds are improving as the project progresses. I have had to lower the voltage to minimize burn through and I have had to increase the speed of the wire. I had turned it down but had to adjust it faster on three separate occasions. I will need to move over a couple of railroad ties to set it on. Slow and steady progress. Eventually, I would like to have enough storage to be able to go get our wheat truck filled with 3-4 types of grain/peas and then store it on the farm. One wheat truck full would get us through the winter for the sheep and the year for the chickens.
