This is the one I have made from a used Yanmar boom.
slick. very slick. but, in this litigious society i wouldn't make my own and post it on line.
That's pretty slick -3Doc.
whats the load rating?
I don't know what it would be rated at, I only need it to lift about 1500Lbs and it does that easy.
I think for safety reasons id make the fork tubes full length and also heavier.
Thats a good thing to do with all the recalled Yanmar booms. hope it don't break, I had to get a new boom on mine due to the recall...
