TDVT, an FYI. As usual with me, after I go through too much work I find a shortcut. I was at TSC (Tractor Supply Company) and saw some sleeves for 1 inch rod. If you don't have a TSC in your area your local tractor dealer probably has some sleeves also. This would have saved me having to drill then grind the short pieces of tubing to fit the 1 inch pins. The sleeves I'm referring to have a hole drilled and tapped for a grease fitting but you could cut and use both ends anyway. They even have different lengths available. The schedule 80 tubing was still cheaper but if you don't want to have to do the fitting, the sleeves are the way to go.
BTW, keep us posted on your build.
