Some of you folks may remember this thread. I finally got some time yesterday to work on this some more. One issue holding up progress was figuring out the lift for it under the FF/20. I think I have that figured out now. So I plan to do more to get this thing working.
Here's a couple pics of yesterday's work.
This lets me see what clearance I have to the underside of the frame. And how tall I can make this blade. Not nearly what I had hoped for. I may have to cut the blade down to 6" tall. Still noodling some different options, but going forward with this.
