Howdy folks
After much time away doing other hobbies, I am going to have a bit of rocketry time coming up. I have recently dusted off my rockets from days gone by, and i am in the process of making them flight worthy again, mostly by replacing the old shock cords with kevlar or something better than old elastic.
Anyway, I plan on hosting a small group launch for a bunch of kids in the neighborhood and I need to build a launchpad for that purpose. I would like to have 3 1/8 rods and one 3/16 rod for my larger models. I figure i could clamp a 2x6 to a sawhorse and drill holes for the rods with no problem, but how would i secure them? Would a metal disc with a 1/8 or 3/16 hold drilled in it and simply dropped down the rod server as a blast plate? It does not seem that it needs to be complicated.
I will also be working up a ignition controller too, but that is pretty simple. A couple of safety cut outs, a flashing light to indicate that its armed, and a big red button on a long wire that can trip a relay. I figure I could power the pad off of a pair of LiPo batts that i run my RC truck with.
Before i bring a bunch of kids and parents over, I will build this up and do some tests with my own rockets to make sure its all working right.
