Wow, it has been about a year, but this launchpad is finally done!
I got a blast deflector from my dad who had a few 11"x11" plates of steel that he didn't need. They are very thin, but still tough. I drilled a 1/4" hole through both the blast deflector and the PVC X in the middle. I used a die to thread the end of a 1/4" launch rod and then attached it with some wing nuts. It worked well for one F engine flight. This was in December. I recently got my own 6' 1010 rail, and wanted to attach it. I borrowed a tap from my dad and put a threaded hole in the back of the rail. I used a long 1/4" machine screw to connect the rail to the pad. It is a bit wobbly at the top due to how small the attachment point is, so I will probably be putting an eyebolt in the top and some taut strings to the legs. I will upload pictures soon!
