I started to do that and then I realized that they would end up being 1/4 inch square. Why waste all of those nice straight pieces of wood? Why not just use 1/4 inch wooden dowels? So that's what I did.
So, I started with the base and then added the platform. A Cheerios box with a piece of 1/8" basswood on top was the perfect height. I do a lot of improvising here! LOL
Now I'm waiting for the glue to dry. The next step is adding the stairs.
I didn't like the finish on the bare wood so I weathered the floor and the platform before I started gluing. So far, so good.
Hopefully, this won't fall apart when I try to move it.
