Thought I would start this thread to provide a place for everyone to post helpful hints/tips/tricks they've come up with: One I used today was, cardboard is cheaper than steel! Seriously, I'm talking about making patterns out of corrugated cardboard to see how things are going to fit together. I was building a receiving hopper for a conveyor, and the bottom of the rear plate needed to match the contour of the conveyor belt. The easiest & fastest way was to trace the belt contour onto a piece of corrugated cardboard. I then trimmed it to size & shape & test-fitted. A couple of minor corrections were needed, once it fit properly I laid it on the 1/4" wear plate I was cutting parts from and traced around it. Cut, grind, and perfect fit first time. (Well, first time with the steel piece anyway!) This is also helpful when working with projects such as my truck deck, where a number of plates meet at different angles - rear corners of the deck angled back tow-truck style. Here's another one: If you have a number of identical steel pieces which need holes drilled (conveyor example again: small flat bars about 5" long with a 9/16" hole at one end which clamp flashing rubber on the hopper, typically at least half a dozen per hopper) stack them up, make sure they are aligned properly and tack weld them all together. Drill through the stack, then grind off the tacks, separate the parts and do a final touch-up with the grinder. Saves layout & setup time - only 1 piece needs to be marked & centre-punched, and only 1 setup in the drill press. Looking forward to learning some new "tricks" from all of you!
