I'm required to have 30" of clearance between all obstacles by law. I have a waste oil boiler to the left of the bin, which you don't see. The bin shown is the absolute largest footprint it can be and in the only position it can be. Some raking of coal will be necessary.

The floor is laid on top of treated planks, which lay directly on top of the gravel below them. 1920's construction. There is no "give" in the floor whatsoever, regardless of weight.

The masonry work is done and the next step is to put the plywood over the inside area for the floor of the bin.

The reason why the pipe is off-centered is because I must keep 30" of space between the waste oil boiler on the left.

Ahhhh, I have been wondering why. Yep, a picture is worth a 1000 words.
As Detail-oriented as I am, I probably would have moved the waste oil burner first. But ya gotta do, what ya gotta do :D

Hey Stoker-man! That's a cool looking waste oil burner. Would that be an EFM product? What kind is it? :)

It's an efm K1200 boiler, modified for waste oil, utilizing a Shenandoah burner and is a product of our sister company, Columbia Boiler.

I guess I need another picture of the solid wall 30" to the left of the waste oil boiler. :)

The floor, 1 1/4" of pressure treated plywood is in place, resting on the stone bed.

The walls are framed out in PT wood, using exterior screws and will be sheathed out with 1/2 PT plywood on both sides.

Is this a display for customers? How about sheathing one side with 1/2" Lexan (interior wall) and 1/4" Lexan (exterior wall) so the customers can see in? :idea:

maybe one of the defunct banks would have lots of that real thick bullet proof lexan to make the "visible coal bin" ?????? 8-)

Here are the remaining pictures of the coal bin in sequence. The only thing left is to paint the masonary base and maybe the walls with efm blue.

I drilled a series of holes on the bottom of the slope for water to drain off, if necessary.

The outermost section of the bin where the worm will pick up the coal. This gets boarded up to contain the coal that falls over the boards in the background.
