Great idea Peter, Same saw as mine and I also tilt about that height, but I use a single bolt at the rear of the saw.
Then to move to under the tree for fresh air just undo one bolt and unplug the saw and out side we go.
might look into the hinge idea after I finish with this art show.
Hows that saw treating you, I have had one bearing crap out on me. Otherwise I love it..
