I may, as they say, gone full retard...
I have 40' of 2" DR11 polypipe waiting to be cut into 40 mortar tubes. My buddy lasered me 40 plywood endcaps. Ordered 75 Talon igniters for the borrowed COBRA remote firing system I'll be using.

Main show will be 40 big ass mortars. With the COBRA it's possible to sync a show to music, but I'm going KISS for my first show. I stuck with Talon ignitors, which lights the fuse. It's simpler, but you introduce a delay with the fuse. The other style igniter replaces the fuse and is instant ignition. It requires some easy mods to the firework. Maybe next time...
His system has 2 banks of 18, so I'll have to chain a few fuses. No clue as to choreography(?). Timing, or whatever. Hopefully my friend has some ideas. If not I'll wing it. Will be 40 shots for the mortars. I have extra igniters, so I may do a rack and chain some rockets, or roman, candles in. May do a couple big cake style in there as well.
If you plan ahead you can buy the mortar racks for cheaper than building it yourself. Lots of companies, just search mortar racks. I'm making 4 separate racks so I can angle them and get some separation on the shells.
The pipe is specific for a reason. Other types may fail, fragment, explode, BOOM!, "MAH FINGAS", WHUT!"

You don't need the remote firing system. Just happens that my buddy is a pro-fireworks guy.

Only down side, is I'm putting about 5 dads and a couple kids out of jobs lighting fireworks and running, lol.
