I work for a company that does alot of the HVAC work for the Gila River Indian Community. Recently I welded a wheel for a co-workers dolly. My boss was so impressed by the quality of the welds that he's taking on small fabrication work for our HVAC clients. From welding cracks in food service equipment to building stands for package units. This project is rather unique tho.
The Gila River Indian Community runs a small theme park called Rawhide which is a 1800's style western town. They have a small show called the 6 Gun Theater. Where they shoot blanks at each other out of revolvers and fall off a 30ft roof after being shot. Really entertaining and funny show. Anyways they have indoor style stage lights, mounted on the top of the surrounding roof tops by unistrut, everytime it rains they destroy $1200 worth of bulbs. They asked us to come up with a cover that would protect them from the rain and be large enough to not overheat the bulbs. So my boss thought of building it out of uni-strut but I knew that it would not look professional nor would it be very sturdy. So I order up 120' of 1" x 1" x .060" steel tubing and welded together a frame to cover the lights and protect them from the rain. I'm going to attach sheet metal to the frame and use some hinges to make a access door for maintenance or repair.
I used 3/32" 2% Thoriated Tungsten, #7 cup with a stubby gas lens set at about 30cfh. I was having severe problems welding on the roof and the wind from south mountain was blowing my sheilding gas all over the place. I really need a MIG WELDER!!!!
Anyways heres some pictures. (The guy in the pictures is my co worker who I was teaching how to prep metal and how to measure angles...) Had to redo a few things after he fit it and I welded it, I also changed the front a bit because we royally screwed up on how we fit 2 tubes together. I have since fixed it but haven't been back out yet to install the sheet metal to get some pics...
