Shop Tip #208

Consider making  your own heavy duty extension cords.  If you get some nice JSOW grade neoprene insulated cord,  you'll  have a very flexible cord that will bend easily, lie flat, and give lifetime of service (no exaggeration). My oldest cord was used when I got it in 1962, and it still works better than those new stiff vinyl ones.  Choose the gauge that suits your tools and the length of the cord, and get heavy duty plugs and receptacles.  If the cord gets damaged,  you can always shorten it or make two out of one. Same goes for power tool cords - replace those cheap vinyl cords on your drill, circular saw, shop vac or other tool, and at least one of your troubles will be over. . .
