new2coal wrote:Hi. I'm in the process of planning my outdoor coal bin. I'm looking at building it with pressure treated 2x4s and pressure treated plywood. I want to make it 12' L x 8' W x 4' H. I will frame out the floor with PT 2x4s, 16" on center, with PT plywood as the flooring. Then construct the walls the same way, using all PT lumber. I'll then nail the walls down to the floor I framed. This will sit in my yard near my house (grass and dirt base). I'll cover the bin with plywood and tarp when it's filled.
Does this sound like it will work? Will the walls be able to support the weight of the coal, by just nailing them down to the framed floor? Or should I reinforce them somehow?
Also, any issue with having the bin sit directly on the ground?
Thanks for any comments you can give.
when making you floor frame put the 2x4 on end make your box frame run 2x4 in the middle for support Then lay your
Floor down nail or screw in down to the frame Take 2x4 make a L in each corner you will use 4 2x4 x 8ft cut them to 4ft
Put 2 or 3 more 2x4 4ft along both sides for support 1 in the middle for the back wall nail or screw the back & sides on for the front door Take 1x3x4ft go in 1 1/2 " from the 2x4 corners in the front screw the 1x3 inside one on each side wall to make a channel take a 4x8 sheet of plywood cut it in half 2ft use this for your door you can slide them up & down in the channel you can take one out when the coal gets low Now take some 2x4 and go across the top front middle and back screw them at the top of your corners and middel side support 2x4 now you will have more support for the sides they
will not move or bow out from the weight of the coal You can also split the front doors if you want to put a 2x4 in the middel on the front of bin you would make a T out of the 2x4 one flat against the bottom of the front floor frame take the other screw that to the first one on end like a T that way you can use that one to screw the 1x3 to make a 1 1/2 " channel for you doors use 3/4" Plywood That might work better being your bin will be 8ft wide You will have more support with that 2x4 in the middel only one side will be sliding doors the other will be solid you door still will be a 4x4 door Just a thought that's how I made mine been using it since 1996 it is under my front porch so it is out of the weather
