I am trying to get everything in the new shop organized and I remembered what a mess the old shop was with battery chargers and cords going everywhere. I decided there was a better way and built a simple box to solve the problem. This is built with SGS materials (screws, glue and scraps) the bottom is 1 x 10, the sides 1x4 and the top a piece of 1x12. It is 32" long. I fastened a 6 outlet metal (heard plastic has had problems) extension cord/surge protector to the bottom. I had a local electrician friend look at all the chargers and confirm that this outlet would handle all of them with no problems. I laid out my chargers on the top and marked where the cords were. I drilled holes with a 1/2" Forstner bit and then cut from the edge to the holes with the bandsaw. I put two 2x2 pieces in each front corner and drilled them to receive a 5/16" dowel (axles for toys). Lined up the top and drilled it to match. These pins are slipped in to hold the top from sliding around. One pin can be removed which allows the top to swivel in case I need to replace a charger. Lifting off the top full of plugged in chargers did not sound like fun. I cut a notch in the end piece for the extension cord. I gave it a coat of shellac to make it easier to blow the dust off and mounted it to the wall. I wound up the cords for each charger, wire tied them, plugged them in, put the wound up cords in the box and called it good. Now they are all in one spot and only one cord showing. Thanks for looking.
