sometimes working for a drilling company comes in handy, especially when you need to make things heavier. my employer bases much of the machine design in the notion: if the part can be made well out of 1/4" steel, it will be indestructible made from 1 1/2". this line of thought inevitably produces plenty of waste both figuratively and physically for me to pick through and salvage. lord knows that my current budget does not allow for the purchase of 100lbs. worth of steel just to be strapped to the underside of a seldom-used motorcycle. so with a bit of patience i have gotten almost all of the components together to make something happen; a year ago at a swap i swindled a dude out of a torch outfit and a handy book all about gas-welding, months ago i salvaged some oxy-acetylene tanks out of a dumpster and now i have the raw materials in hand. all that is needed is some gas and rod and a little instruction. and it just so happens that i have a local pal, experienced in the gas-welding process, who will instruct me in an exchange for a face-crushing burrito.
