Ok, here is mine- it's not organized at all yet, needs shelves, hooks and drawers before everything is moved in. tack locker 005.jpg
We opted for a separate top compartment for seasonal and infrequently used things. Right now there are just saddle pads, a couple blankets and coolers up there. The bottom will be tack, meds, grooming and everyday type stuff. tack locker 008.jpg
Here is the roof. It's framed in 2x4s. With a 2x4 in the middle for support (we have things stored on top of the locker, too, so it needed to be strong). The floor and shelf for the top compartment are framed the exact same way, except they have a 2x4 every 2 feet (2 total - you can see them above my saddle in this pic) unlike only 1 in the middle for the roof. tack locker 009.jpg
Here, you can see the main frame in the corner. We used 4x4s in every corner. For the saddle racks we used a separate 2x6 - it stabilizes the back wall too. There will be 3 saddle racks eventually so we needed something hefty. The 2x6 is attached to the 2x4 that frames the floor and the 2x4 that frames the top compartment, we just beveled the floor around it. tack locker 010.jpg
Here is another shot of the 4x4s... I should have taken a better picture, but you can see at the top of the pic where the 4x4 meets the 2x4 - Ok, let me try to explain this - We cut out sections of the 4x4 to wedge the 2x4s for the floor and upper compartment into. That way it's really secure. It's like the 4x4 had a [ shaped 2x4 space cut out of it. tack locker 011.jpg
I forgot to get a picture of the floor, but it's just a solid piece that's sitting on top of the 2x4s and we beveled each corner to fit snuggly around the 4x4s.
Whew, sorry if that's hard to understand - tried to explain it the best I could, but I'm not very good a construction terms. Hope it helps!
