I whipped up a launch pad using John cockers plans. I modified it a lot and used square tube steel since I can weld steel. It came out pretty well, so good I thought about making a few and selling them if the price was right. I used 1 1/4 square tube and 1 1/4 flat bar that was 1/8" thick. I also used 2" flat bar for the main T connect. The main pivot pin doubles to lock the unit in place when folded for transport. I also used some old hard drive magnets to secure the legs during transport. I also have plans to secure the stakes inside the legs using foam to create friction. I'm still working on that piece. I hope to have it painted by this weekend. Using high heat manifold paint. I'm curious to see how well it handles AP motors.
