This is a very simple rack I made to hold the screw guns, drills, and electric shears in the tool crib at the construction company I work for.
Step 1: PVC Pipe
I used scrap 4" PVC cut to 14" long to accommodate the length of the DeWalt (DW257) screw guns that were used for my measurements.
Step 2: Cut Notches
A 2" hole saw was used to make a hole 3" in from one end of each of the 14" lengths of 4" PVC and a jig saw was then used to cut into the hole from the nearest end.
Step 3: Drill Mount Holes
At 90 degree angels to the notches a hole was drilled with a #6 wood screw countersink bit. One set of holes was drilled out larger to accommodate a screwdriver to pass into the pipe for mounting.
Step 4: Mount to a Board/Wall
I mounted the pipes to a scrap of 3/4" plywood cut to ~2'x4'6". I could have mounted it directly to a wall but opted to mount to a board so I could move the entire unit as necessary.
Step 5: Make Improvements
I also used a cutting of leftover pipe to make a basket to hold screw tip, drill handles, and other accessories. This was made by cutting a 45 degree angle on one end the screwing it to the board from the backside.
Step 6: How to Use
Each pipe is mounted with only two 3/4" #6 wood screws but the interlocking formation that I used to mount them makes for a strong mount. All the same I would not recommend holstering your heaviest drill on the lowest tier.
The screw guns, drills, and electric shears all have the same handle shape and simply slide into the pipe with the handles falling into the notches. The cords must then be gathered up so as not to drag on the floor. I wound the cord into itself but tape, Velcro, or cable ties would all work.
I hope you all find this enjoyable and hopefully useful. Please ask questions and leave comments.
