FILENAMES: WORKLAMP.GIF DESCRIPTION: These are drawings of a shop built worklamp. Posted by Ted Edwards . Ted provided the following description: ----------------------------------------------------------------------- A Free Standing Worklamp E.M. (Ted) Edwards 000718 Ted_E@bc.sympatico.ca See drawing WORKLAMP.GIF. I have built two of these and find them very handy. The base is a used brake disk from a 3/4 ton van. The column is two 30 inch lengths of EMT, 3/4" (nominal) for the lower piece and 1/2" for the upper. A circle of 1/8" steel plate about 5" in diameter is used to join the lower piece of EMT to the brake disk. A 6" piece of EMT or a 6" long, 1/2" pipe nipple is used between the two electrical boxes. The deep drawn steel boxes with metal cover plates are best for this application. In addition you will need, a 1/4-20 wing bolt (I made this from a hex head bolt and a bit of scrap) and nut, a 300 watt outdoor type halogen lamp, about 20 feet of #12/3 heavy duty extension cord wire, a rugged three prong plug, a switch, a duplex receptacle and a few additional feet of wire. I flared the bottom of the 3/4 EMT to ease the movement of the cord and drilled a 5/16" hole near the top for the wing bolt. (The flaring was accomplished by setting the ball of a ball peen hammer into the end of the EMT and smacking the face with a heavier hammer.) I then made a hole in the 5" diameter disk just big enough to let it slip over the 3/4" EMT. This disk was then slipped down over the EMT and welded in place. The 1/4-20 nut was then welded over the 5/16" hole. One of the ventilation holes in the brake disk was enlarged to allow passage of the cord and the 3/4" EMT and its attached 5" disk was welded to the brake disk. The two electrical boxes, the 1/2" EMT and the 6" long piece of EMT or pipe are welded into the two electrical boxes (see drawing). The usual fittings used to join these pieces in house wiring just aren't up to the job. The cord is threaded through the hole in the side of the brake drum and up through the nested pieces of EMT into the lower electrical box where it is connected to the duplex receptacle. The ground should be connected to both the receptacle *and* the box. The lamp was secured to the top of the upper box with the lock nut supplied and wired through the switch to the receptacle in the lower box. My unit has the outlets and switch on the opposite side to the face of the lamp. Power tools can be plugged into the receptacle so the unit serves as both lamp and extension.
