I'm going to build a shelf for my Lego project, which is the Saturn V rocket. This rocket was part of the Apollo program back in the late 60's and early 70's which took humans to the moon, collected rock samples and then returned them to Earth. The V in the rocket name is the Roman numeral five.

This Lego rocket is 39" long, comes apart to show all three stages along with some of the inner workings if you wanted to display that way. As for me, I'll be keeping it all together and then setting in on a wooden shelf in my office. With all that being said, lets get started with the shelf project.
 

I'm going to make floating shelves for this project, which I've done before. But this time I'll be making all the hardware instead of buying it. Now this shelf won't have much weight on it so the round supports will be 3/8" diameter steel in place of the other ones that were 7/16" diameter.

I'll be using 3/16" thick steel plate for the brackets that screw into the wall, which is the same if you were would buy them. The piece that I cut off (right side) will make my two bracket pieces.
 

Here are what the brackets look like that will be screwed to the wall. I'll be using 2" long drywall screws to attach the brackets and I'll be using 1/4-20 set-screws that will screw into the 3/8" round support rods to the brackets.
 

Here are the 3/8" round supports that are 4 1/2" long. One end is threaded for the 1/4-20 set-screws and the other  end is chamfered that will go into a hole in the wood shelf. Speaking of wood, now it's time to start on the shelf.
 

I had a piece of oak that was perfect for this project. I only had to remove a few inches from it.
 

The arrow is pointing to my story stick. I centered the story stick above my brackets on the wall above, and then transferred those lines onto my stick. Then I transferred those lines from my story stick onto my shelf. Now it's time to drill some holes.
