Thanks for the latest 2 cents worth - it is way more valuable than that. I am in the process of constructing a rear blade. That choice allowed me to justify a Hypertherm Powermax 45 plasma cutter to my wife :laughing: - wow - is all I can say about that.
JoeL4330 sent me a picture of his Landpride with all the bells and whistles and once I saw that, I was hard pressed to be satisfied with the most basic blade. That's probably a mistake on my part but it's in my nature.
So here's what I'm doing. I'm kind of following the Landpride format with the option of adding hydraulics later. I have fastened two 7 foot x 3/4" thick blades (cut back to 6'-3" for my JD 2320, about 14" tall) together using 5/8" thick 23" diameter pipe cut appropriately as backing. Welded into this backing is a rectangular channel that allows the main rectangular vertical support tube to pivot, thus providing about 8 degrees of tilt either way. The blade can be inverted top to bottom to give me the choice of a very sharp edge or the flat worn edge. I have rightly or wrongly assumed that I can benefit from floating tilt with skids at either end of the blade and a guage wheel in the middle. It's too late to turn back on the tilt so we'll see (of course I can always just lock it at level - 0 degrees). All this is going to be over build and heavy but I have been assured that heavy is good.
I also am constructing the main member that goes from the iMatch out to the blade so it can swing to offset the blade. To do this I will be creating taller pivot points for rigidity. The blade itself will also angle via a pivot point. The square tubing I am using is 3x3x1/4 beefed up when necessary.
After typing here for a few minutes I think it makes more sense to include the pic of Joe's Landpride because it, in scaled down form is my guide. And my daughter has just taken 3 pics of this grungy looking project (my camera is fried). Two are of the blade proper and one is the piece that attaches to my iMatch 3-point.
I am not a mechanical engineer, machinist of mechanic so can't claim what I am doing is particularly great but those of you that build things will appreciate that there is a small sense of pride involved (very humble pride of course

) Caviat: 90+ % scrap material, including 23" D. heavy pipe pulled from my fire pit after 25 years of burning, grader blades found in county ditch etc.
