I'm in the Bozone, but I use a chain hoist hung off the roof trusses. I ran double 2x12's the length of the building, tied to the truss bottom cords and vertical stiffeners.
I used to write into this forum all the time, but there is a moderator "bear 45/70" who is a real first class A1 as*hole. He thinks he knows everything, and if he disagrees with you he will not hesitate to heave personal insults your way. Sort of a dictator type.
These forums are supposed to be a friendly free exchange of information, something enjoyable to help out fellow FE nuts like myself, Not a place to here more crap like in a grade school recess setting. It's no fun anymore with people like bear around.
I filed a complaint, then received a email reply that I did not do it correctly, tough luck, and get lost.... was the basic response.
So I have given up on what was a great forum. Phil
