For the micro star fountain, I would go with C sparks instead of Ti/Al. You can't really see the microstars... Pretty heavy candle btw, and nice giant fountains.

This is my first attempt at shells making. All are three inch ball shells with scrap cloth used for pasting. In two shells the spollete time was 4 seconds and in others it was 3 seconds. The burst charge was mepco 999 Al based.

Lift powder was 60gm in each mortar.

 

My main concern was to make the shell reach a proper height and not to go blind. Now, I can concentrate on priming stars properly

In one of the pics I was checking the clearance between mortar tube and shell.

Just enough for the ball shell to slide down with its own weight. Around 1.5mm approx

That should be enough.

Hi debu,

 

The commercial charcoal available at my side is all made of keekar wood.
