yes, I later saw that was not just my idea because I later have seen 2 at farm auctions that others made. What I did not know (in your second link) is that they are also commercially manufactured. One thing I don't understand is what use they are unless you had them supported by wheels since a forlift lifts much more than a 3 point can handle. The mast itself is pretty heavy.
