I recently purchased a six pound whistle rocket kit from Wolters. The
kit arrived with a four inch spindle, isn't that way too long for
whistle mix? My first whistlers exploded confirming this notion.
I've been pressing whistle rockets for some time, so I think my fuel
and pressing is OK. I am awaiting an answer from Wolter's, as well as
yours! Thanks, Dan ps, this tooling is beautiful!
