Thanks Trev. Now engineering in my mind how to make the base more stable. That's a lot of weight wanting to pull it backwards. I think I am going to cut 3/4" plywood the width of the base and 24" back and screw it to the wood. I may also make angled braces from the bottom to maybe 24 inches up along the back uprights. The screws holding the base together are as tight as a power screwdriver and ratchet can get them and it still wants to waver a bit. I'll figure it out. Just finished adding the last piece and completing the wiring and everything works.
