Grader mod for BB

[Tig]

Sorry for the delay in more pics. Here is one of the grader as it is today. I extended the tails so they could be used like gauge wheels.

Here is a pic of the grader on the BB. You can see the bolt securing it on this side.

The BB cutting edge catches a notch towards the back of the grader to secure it.

Here is a view looking down at the back left of the BB grader. The area behind the second blade became too small on this side. It still seems to work well in spite of that.

How much of an improvement is this over just using your bb alone?

Are you still using the single gauge wheel or did extending the angle iron take the place of the wheel?

Have you figured out a way to get it to crown material on one side or the other?

When you welded up your blades out of 3x3 angle, did you weld a flat bar on the bottom to form a triangle or do you think the angle is strong enough to use as is?

Some of the other graders mounted their blades at a tilt from vertical, say 35 degrees, if I remember. Do you think this would make any difference?

Thanks for sharing your ideas.

To answer your questions.....

How much of an improvement is this over just using your bb alone?

-The dual blades move more material and the BB cutting edge prevents a wind row from forming. That makes it quicker to touch up any areas of the road that are showing wear. The skids and tails make it more forgiving. It is much easier to control than a BB on a road that needs maintenance as opposed to major work. I have both types of roads to deal with at the moment. All that being said, I only have a few hour use to go by and limited BB experience to compare it to. I am satisfied that it does a good job.


Are you still using the single gauge wheel or did extending the angle iron take the place of the wheel?

- Angle iron replaced the gauge wheel. Works very well.


Have you figured out a way to get it to crown material on one side or the other?

- To get material to move to the other side I would run the grader in the opposite direction. eg; The grader moves material right to left so if I follow normal traffic (drive on the right side of the road) I build a crown as I drive up and down the laneway.


When you welded up your blades out of 3x3 angle, did you weld a flat bar on the bottom to form a triangle or do you think the angle is strong enough to use as is?

-Yes, I did box in the the triangle, but had to leave gaps to access the bolts that secure the blades. Grading ins't a huge strain on the cutting edge but catching a rock is.


Some of the other graders mounted their blades at a tilt from vertical, say 35 degrees, if I remember. Do you think this would make any difference?

- My blades are at 45 degrees because I did not realize others prefered a steeper angle. Seems to work well on a rain softened road. If I had known that there was a preference I would have followed suit.

I hope that answers your questions.
