I’ve been playing around with this.
Drilled a new platform hole in the center, close to the edge. Replaced 5/16 bolt and plastic liners with a 3/8 quick release pin off amazon (kept nylon washers, but they are a real trick to get in there).
Replaced standoffs with DanO standoffs (had to file out the recessed part because the Hawk tube is wider). I will need longer bolts too.
I drilled another hole at the top (now bottom) through the original cross bolt location to get the second standoff close to the end.
Basically, it can’t fold up all the way with how it’s designed, so it’s really hard to get it to cam properly, but it can be done. On the ground. I’m not stoked about trying it hanging from a saddle.
I might just go back to the original configuration, but keep the 3/8 pin for the added strength, and maybe add a second strap for stabilization.
The consensus is correct, IMO. This will probably be a backup, a platform for one of my kids, or just a tree seat.
But, I’m open to any suggestions that don’t involve welding or a grinder. I don’t have those capabilities at the moment.
