Up to this point, all my work has been done with the oxyacetylene torch. And I can honestly say many works to come are going to be done by way of the torch. But I have always being curious about arc welding. Especially since the weld is instantaneous because of the 10000 degree heat. This is especially useful in projects that would take a considerable amount of time to complete with a torch such as building a welding table.
These units are simple in design as they consist of a 12 volt gel cell battery plus a couple of heavy duty 400 amp cables and rubber insulated clamps. These are extremely useful items as the batteries they have are powerful enough with its 400 amps to actually jump start a vehicle when its starting battery is totally dead. Its peek power rating is approximately 900 Amps. There is AC adapter which comes with it for charging the boost battery as well as a 12 volt cord for charging it from your car as you drive.
Another large plus of grommet is that while you are happily making holes for nails and hooks you might not realize that you are also putting in holes made perfect for bungee cords, the grommets intended purpose. Now you can suspend your cardboard walls overhead and make them ceilings. Shifting walls and ceilings are easily made by stretching out a sheet of cardboard so it is suspended mid air. Using a PVC or 2 x 2 lightweight frame to stretch and anchor the bungee's to. Moving the frame can easily be accomplished with air rams or motors. Even easier is to suspend the sheet on a frame and have it anchored so you can manipulate the cardboard itself. Probably somewhat safer as well.
You do not have to have a compressor, some people prefer to use a CO2 bottle, but that seems somewhat expensive. Some of the discount tool companies (like Harbor Freight) stock inexpensive compressors. Probably the most import thing to a good finish is good surface preparation. In other words a good clean. Smooth surface. As I have gotten older I have developed a tendency to prime the surface and after that dries well to sand it with very fine grit paper. Try 3200, 2500, in that range.
First, let me tell you what turns me on the most about a really, really clean bike. I drive up to a friend's place and get the same reaction I've gotten since I started riding 38 years ago, "man is that all you ever do is clean that thing"? No, I reply, my wife cleans it for me. It's worth it just to see them turn that funny shade of green. No, my wife doesn't clean my bike and that isn't all I ever do. I'm like anyone else I'd rather ride the thing. So why don't we get right to it, shall we?
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.
