Thanks guys for the encouragement. It helps to finish a project when you think that others might enjoy seeing your work and share in your triumph or failure at least vicariously. I know that is true for me as I see your masterpieces.
I finished the gauge wheel setup so that I could "test it out" on our parking area. I had smoothed it as best as I could with my BB but it was not where I wanted and I could not get it better so I decided to finish the gauge wheels for the RB.
Since they will not always be needed I made a way to raise them past vertical so that I could get as close to a building as possible. I used a sliding rear bracket that can be pinned in the down position or in the vertical position. Theoretically I could put more holes in the bars the make the frame and pin them in any position, but I could not think of a reason that it would be necessary.
I wanted to be able to spin the blade around so the wheels had to be a distance from the blade. The side benefit of that is the better "grader effect." The draw back is that the thing is so long. You really have to be aware or you will smack something when you turn sharply.
They also needed to be adjustable. I accomplished this in two ways; 1) I put a CAT 0 toplink that I was sent by mistake in the place where others could have placed a
hyd cylinder, 2) I used washers for spacers for side to side fine tuning.
