Since the primary purpose of this project is to learn, we will keep the design simple, and we may
not take steps to avoid extra work if it will show students something interesting.
Basic Design: All steel. 6x6x1 inch upper and lower plate halves. 1 in diameter hinge.
Since 1 inch thick steel plate at 6"+ width is not easy to find at small quantities and reasonable prices, we found a deal on a piece of 3x1x36" cold rolled 1018. We cut four 6 inch pieces of this and welded them together to make two 6x6 plates. Students had big fun using the oxy-fuel cutting torch.
First pic is the bevel we put on the plates to prepare them for welding. 30 degrees with a 5/32" land.
Second pic is a finished plate. Stick welded with a 5/32 open root, E6010 root pass, E7016 fill and cap passes.
