I did not touch anything since NYE, absolute hiatus... But I just regaining my memory of what I wanted to improve.
Maybe you guys have some interesting thoughts on this.
First point is a very simple one.
My standard procedure has always been to glue the fuse into the tube so that it touches the propellant grain with it's tip, at the tube wall.
I've had a couple of rockets failing to ignite that way...
With smaller rockets I dont have the possibility to form a ring around the spindle or something.
Some form of additional prime is obviously an answer, but I dont want to light the core, so the prime must burn not too vigorous and not to sparky.
And second, speaking of sparks, some of my tools have very short spindle collars, so the propellant is quite exposed.
How do you protect your rockets from accidental ignition in "fiery environment"?
Giving it a classic paper wrap is imho not a good idea with hot whistle fuel...
