Measurements of mine:
20" wide, 46" long on the bottom, and about 5" tall.
First, let's start with the base.
I used 8 pieces of wood about 20" long. With the amount of wood I specified, you can make your pieces up to 23". You cut them all from 2 1"x6"x8' wood pieces.
Then you need two pieces for underneath at about 48" long. (Cut one of the 1x6x8 pieces in half)
I also sanded down all the edges to save everyone from splinter's!
Line them up, place your two long pieces along all of them and screw it all down).
Optional: Stain them for a darker wood.
Next, you'll need to clean all of your steel pipe and fittings. My dad gave me this stuff- LPS Electro Contact cleaner but I think you can just use a warm, soapy rag to clean off all the gunk.
Now it's time to put all the pieces together. My dad did this part for me (he kind of took over) but what you do is grab some wrenches and just tighten this stuff together as much as you can. Start off with the top piece and attach the tees. Then the side pieces, the nipples and caps. And last, the floor flanges.
Then, measure out your top (from middle of one tee to the next) and screw floor flanges onto base accordingly.
Done! Here are some close up shots (:
