Eddie,
I hadn't planned on a front support. But, I will see how stiff it is once it's built. I could add them later if necessary. I plan on using 2"x2" 1/8" angle on it and a diamond plate top with the diamond plate on the underside, shiny side up. I will be adding firewall insulation under to keep some of the heat away.
The scrap cost me 10.00 for the supports. I have most of the angle and the diamond plate. I need another 8' feet of 2x2 angle which I will get from the recycle place today, firewall insulation (should be around 20.00), the brackets, and a rattle can of paint. I checked on a 'frame only' from the local massy dealer and they wanted 268.00 for it. I'll come in much less and it's kind of a fun project.
Eddie I bow to you on the lake project. I am totally impressed. My little projects don't even come close to your skills!!!
Marty
