A nice bonus of this is that all the wood and door were scrap so I didn't have to buy anything for this counter.
This instructable was easy to make and only took a couple of hours form beginning to end. The tools I used was a power saw and a cordless drill.
Step 1: Setting Up the Wall.
Step 2: Buildint the Counter From a Door.
using the hinges, I connected to another 2x4 that was 62" long
Step 3: Mounting the Counter
Having 2 2x4's to mount the counter gives you additional space to place things on them such as a power strip. I have a plug right above the counter to work with, but if I am using lot of items, a power strip would be helpful.
Step 4: Making Legs for the Stands.
Where the width of the door was 30" wide and the wall was 62" long Each leg would be 30" wide.
My garage has a slope in it so the one side of the counter was taller than the other. In my case, it was 35" high on the other side.
Using some hinges, I secured the legs to the wall.
Step 5: Using the Counter
I drilled some 1/2 inch holes on the sides which gives me the ability to put in a arm style lamp from my other workbench without having to clam and unclamp the holder. It is nice to add additional lighting when needed.
