If I am understanding your hardware design right, it looks like the launcher heads can be tilted (and locked) to the left or right of the yellow rail/hardback, but not in the direction "up" or "down" the yellow rail. Is that right?
Where did you get the angled pieces of metal if you don't mind my asking where they made or bought at a hardware store?I need to get a hold of something like that for my home built pad right now I am using two eye bolts back to back with a drill chuck screwed on top to hold the launch rod but it doesn't hold up to heavier rockets well.
Making a working Alt/azimuth launch rod head really doesn't have to be all that involved or hard to make.
Below is a head I designed for one of our Clubs 6 pad Racks, They work like a charm. We also have tons if kids using the pad also and only occasionally will a rod get bent.
36" really is a minimum length for most model rockets flying with the exception of Micro's . I believe it's still part of the sporting code, if not is should be for 1/4A-D models. Shorter rods just don't give the models enought time to get up to speed, unless they are all very small and light weight. I'd suggest sticking with 36" rods for safety sake
