I bought Archetype Rocketry's clever and compact Cable Cutter a couple of years ago because it enables dual-deploy from a single volume. After struggling to find it all day I finally ran the following test tonight:
They recommend 0.1 ml of Pyrodex but all I have is black powder. I could probably get away with 0.05 ml but, considering the parachute "burrito" will be outside the rocket when the cable cutter fires, I think I'll stick with 0.1 ml just to be sure. I plan to fly a minimum diameter AT 1417K185 on Saturday using this system so wish me luck and [almost] Happy 2016!!
