Still can't figure out how to make it a powered rotation so, it will rotate freely.
Made some progress and I Muggy welded with great success..
wooohoo!!!!!!!
The parts I "welded" are the lower parts of the knuckle- two pieces of channel back-to-back. Sweet!! I am happy with the articulation of it, turned out real nice for me. Man I need some hydraulics!!!!!!!!!!
