Always have a little extra room, sometimes the coal guy has extra.

Mine is 4 x 12 x 4 = 192 Cubic FT Approx. 4.8 tons,

I have just over 5 tons (5.05), but have to ramp it up quite a bit in the center to get it all in! It is FULL! I told him 4-4.5 ton, and ended up with a bit more!!

I burnt about 6 ton last winter. I will get a pallet of bagged (1- 1.6 ton) if I have to in the early spring if I run out.

In process of building my bin. It's 13ft by 4 1/2 and will be good to about 5 1/2 H. Losing some room in my woodshop but willing to do it I haven't looked forward to winter like this in a long time LOL

My bin is 4x8x4 with two of the sides sloping downwards towards the auger for my stoker. I burn 9 tons a year. I could fit 3 tons in it. Then last year I got 3.5 tons in one delivery. It fit. I had some more room on top. So then I raised 2 sides another 16". I just got a delivery of 4.5tons. The bin is FULL. PACKED FULL. OMG its sooo FULL!

This past summer I installed foam board and drywall over an exposed stone wall in my kitchen. And I had a radiator on the 1st floor that didn't work. The valve was frozen closed. I replaced it. I'm hoping, praying that this year I only have to burn no more than 7 tons. I think this improvements should work.

This coal bin actually is more of a coal handler. It holds 800lbs, of rice but enables me to cleanly load my scuttles with little or no mess. I buy bagged Kimmel by the trailer load with a few friends.

Did you do the welding/metal work?
Is there a latch to keep the wind from opening it up?
Does the chute door easily slide in and out under the weight?
I like it..Looks good

### Re: How Big Do You Make a Coal Bin?

A few years ago I traded a "Budman" beer mug for a welder. So after making a dump trailer I became a welder for fun. Getting back to your questions, the lid needs a lift of about 6 inches prior to the gas shock taking over. The blast gate from ebay works quite well, the coal just crunches when closed just like our stokers. Others have made knife gates using steel and wood, I just cut to the chase and went with all stainless. Yes I did all the fabricating in my garage. Some people say I have too much free time. But really I like to putter around instead of watching TV, coal burning has become quite a hobby over the past 27 years.

### Re: How Big Do You Make a Coal Bin?

I have a friend that sold me an old ATM machine house.
8x9x3 I built a slide in it and put a chute on the one end. It will hold 4.5 ton of coal according to the calculations you guys have posted. I put a "slide" in there to get the coal to come out the cute. 4' up off the floor on the one end and on the floor on the chute end.

I love it and it is working well. If I can post pics I will lets try.
Oh I bought a grain elevator for \$40 at and auction and put \$70 worth of bearings in it to get the coal in the roof of the bin off my trailer.

I have a total of \$200 in this setup. With our surdiac stove we only need to get coal every other day so it works out well having it outside.

Thanks for the help with the #'s guys that helps a lot because we burn 4 ton a year so 2 trailer loads of coal and we're set for the year all in one shot. I used to have to make two runs at different times due to lack of storage. Now I can go over the summer get all I need and be done.

This is a very helpful site I'm glad to have found it.

Having that ATM house coal bin is a great storage idea.It's the same as having money in the bank.
