So I'm about to purchase the supplies to build my bin. 8x16 5 feet high.

I'm thinking either rough cut 1x8's or 1/2 plywood. Guy at work said the plywood is stronger.

2x4's on 16" center

Your 520 is already in?? I'm jealous.
If I'm not mistaken people are putting the 2 X 4's 12" on center and using 3/4" plywood. Don't forget to lock it to the floor. I went a little nuts and used 8" cinder block, drilled into the concrete, installed rebar and filled the first 3 courses with concrete. It's not going to move but I think it was just a bit of overkill. :)

I'm not sure which is stronger ... either should be suitable.

Somebody commented on the studs being on the inside of one bin. My thoughts are, that the studs should be on the outside for strength. If the suds are on the inside, the coal is pushing on the outer (plywood or boards), but ... it's only being held by the fasteners (nails/screws). If the studs are on the outside, the weight will be pushing on the studs.

Check out a horse paddock sometime. ... posts on the outside. ;)

The studs will be on the outside.

I was just looking at a cost factor. 1/2 plywood is $15/sheet @ home depot. I can get 1x8 for 2.50 each. So $16.50 for the same area.

3/4 is $24/sheet so I was hoping to go a little cheap with the box. And I plan on anchoring it to the floor.

And no bill. I'm not finished. Barely started actually. Probably be around November. :sick:

Aren't six rough cut 1x8's going to cost $15? Even at $ 16.50 that sounds like a pretty stout bin material. They used to use rough cut one by's to form concrete walls in the old days. From what I've seen, concrete is way heavier than coal. I wouldn't hesitate to use the 1x8's. Can you get alot for that price? :) Scott

I would use fencing. It looks and weathers better than plywood. Just add an extra post per section and then secure a 2 x 4 side to side to keep it from spreading.

I used 5/8" OSB and have had no problems. As long as the studs are on the outside it will hold fine. I think the main thing you need to be sure to do is fasten it to the floor in someway to prevent the bottoms from kicking out. I used one of those nailers that uses the .22 cartridges to nail it to the floor. Holds 4 ton and is solid as a rock. Good luck.

Persoanlly 2x4's on 16 in centers with 3/4 or 1/2 is what I would build it.

For now it does but those nails are going to deteriorate over time, they don't go very deep etc. Instead I'd suggest drilling some holes into the floor and get some rebar or pipe.... it will never move unless the wall itself fails and even then you'll ony have a partial failure.... with the 2X4 that goes up against the rebar you're also providing support to the entire length of where the studs meet the footer. All the weight is transferred to the rebar so there is nothing to fail. I should note that I've seen a lot of bins fail usually when I was in them and they always failed on the bottom. Either the studs popping off the footer or the entire footer failed:

I agree with Richard. Those ram-set nails are OK, but over time might start to fail. Simple drill through the footer into the concrete and set in pieces of rebar. Cheap insurance.

To quote my father... "wtf are you putting a hole in perfectly good piece of wood if you don't have too..." :lol: If you don't want to use the extra 2x4 you can always put them next to the footer. ;)

If I may jump in here, I just finished my bin. 8x6x8 I secured my 2x's to the floor with 3 red head 3/8 or 5/16 concrete anchors on the 8' length and 2 anchors on the 6' length and a bunch of 2 3/4" tapcons I want to hold 5 or6 ton think it will hold :?:

mark.

I used 7 - 2 3/4 tapcons screwed to the floor on 8' wall and it's holding 4.3 tons of nut :yes:

I suggested drilling because I thought there was no room to add anything outside the wall. For sure, if there's room then just some pins outside would be the cat's meow.

Razzler....that's a beautiful bin.
