I am somewhat embarrassed to show my efforts so far but I will in a separate post as I hone my skills. But for now I will do a assessment of this technique. So let me start with the pros of arc welding. One is it is less expensive for equipment than MIG and TIG welding. Secondly, the heat is instantaneous and would be excellent for tack welding armatures and metal furniture that you can finish with oxyacetylene. Thirdly, because you are not warming up the work with a flame, the heat is highly focused and warpage is greatly reduced. Finally, this particular welder I have is very light weight and there are no gas gauges to watch over.
I will discuss safety first. You should ideally wear chemical splash goggles while working around a car battery. Batteries can potentially produce explosive hydrogen gas which can explode and release sulfuric acid. Although this is very rare, it is important to avoid any sparking around the battery and wear eye protection. Always use prudence and common sense when working around cars.
As far as materials you have a good choice. There is always the old standby: balsa wood. Balsa is light and easy to cut. A better choice might be plastics, in which case I would recommend using plastic from Evergreen Scale Models. That company produces a wide variety of shapes (sheet plastic, I beams, corrugated, etc.). Plastic also produces plastic in many construction type shapes.
Installation time: take off all the switch and plug covers pull the boxes out if you can or unscrew the plugs and switches to leave ½ inch behind them. When all tile are dry you can screw them back down for a tight fit. Draw on the wall where any key pieces will go with magic marker or pencil but you will cover it. Using the trowel, comb the mastic/adhesive. Note: Types of adhesive. In order of strength.
The assembly instructions had me using a bolt, two washers, and a locknut on each leg to hold it in place. Problem is, that means that the legs will wear on the sideplates. Not a good idea. I bought 8 more flat stainless steel washers and slipped those washers in between the legs and the sidepanels. Now the legs will wear on the washers instead of the sideplates. This makes the leg securing assembly consist of the bolt head, washer, sideplate, washer, leg, washer, other sideplate, washer, then the locknut. So each of the legs now has 4 washers: two washers on the outside of the side panels, and two washers to keep the leg from rubbing on the sidewall directly. Again, don't overtighten, or the workbench won't fold up.
Three possibilities come to mind. One is the old standby balsa wood. Balsa is fairly cheap and easy to work with. Several glues can be used with balsa: Elmer's, wood glue, super glue and even an adhesive that is used it wooden model construction. Balsa can be cut with an Exacta knife, or razor blade using a straight edge for straight lines. Sheet plastic is the second material.
