Duragrader Update

[sandman2234]

Actually, I just got back online a few minutes ago. Decided to throw a computer online so I could look for a set of tires for my tractor. Seems both fronts are flat sitting in the driveway. I fixed one yesterday, and one the day before. Time for some new ones! I was on a borrowed connection before.
I think when I get around to building the 7 foot model, I will probably slot the boltholes that the blades mount in, and make some sort of retaining bolt to keep them from working loose (Stop adjustment) Won't be hard to do during build, but more of a pain with yours since it won't fit in my Bridgeport!
You might try adding a 3/8" or 1/2" piece of wood to the bottom of the two side runners, to lessen the bite until you get everything figured out. It might take more or less strip of wood to get the digging dept just right, but a strip of wood is easier to work with than a strip of metal. Drill a couple of bolt holes in the runner and counter sink the bolts in the wood. Use some old pallet oak, or something like that, that is harder than pine.
You have my number in case you need any help.

The more I think about it, the more I believe the duragrader may crown on either side. Since the blades extend to such depth, if you lower the front and raise the rear, it will crown to the left. If you raise the front, it will crown to the right by digging in at the left rear. Crazy, and probably hard to get an exact feel for what you want it to do. Also probably takes a lot of seat time to make it do what you want it to.
I think it might be easier to lower the front and raise the rear, allowing the dirt to fill in any potholes.
Let us know how you are doing, mastering it.
