I was planning on building a Catherine wheel but i dont know the best way of making one. I previously just made a wheel with four pieces of visco fuse on each side so provide the propellant but i would like to amke a much larger one than that but fuse does not work.
Has anybody made a big Catherine wheel and knows of a good propellant.
~Many thanks
