I tried the cross strap to see if it would do anything for lateral suppert. It really doesn't do anything honestly. The gate is 11 1/2 feet wide and I didn't hsve the choice to make two gates due to structure limitations.
I just went to my local bike shop and asked for a blown out mountain bike shock, since I only needed the spring set up. So $20 bucks later I came out with a Fox shock and a 400# spring. It works perfect!!
My saying was when I was building it was "it's only a gate" don't oer do it.
Did you try it w/o the wheel, or will the post not hold "her."
