Hey Zach,
I was going to get to that... Here's a couple additional pics that show it better. I put two #10-24 machine screws through the aft CR (one on either side of the igniter conduit). On each screw I added a washer, lock washer, and nut to keep the screws in place on the CR and to attach a terminal to which the igniter leads are soldered (the other end of the lead wires will be attached to the WRC+ 2nd stage ingnition output in the av-bay) . Then I added another nut and a 10-24 thread coupler. My intention is to use two 10-24 screws in the end of the tread couplers as screw posts to attach the igniter wires for the upper stage motor. The main reason for all this added complexity was to make it convenient to attach the igniter wires out at the pad (I could have used the twist and tape method, but that's not my preferrence). I did not want to have to run igniter wires through the conduit, open the av-bay, attach the wires within it, close the av-bay, pack the drougue chute, and insert shear pins at the pad (rules prohibit inserting the igniters until you're at the pad). Like I've said earlier in this post, I have not built or flown a 2-stage HPR. If anyone has any clarifying advice to offer... I'm all ears.
