Built like a hummer from an off-cut of 19 mm ID tube, about 50 mm long. End plugs of wax treated cat litter, 4 mm spin vent and case wall treated with waterglass.
Propellant of Chrysanthemum #6 composition. Fused with blackmatch and meal-NC paste. The spin vent was at one end of the case, not in the middle like a traditional hummer.
Slow spin up.
Not all that impressive of an effect.
I guess the Ti/meal composition has ruined my love of charcoal effect.
