nordicwolf Posted March 28 Share Posted March 28 So far I've had pretty good results with BP motors...4oz core burner with 60:30:10-ish comp; 4oz end burner hot ballmilled BP; 1 pound hybrid with hot BP. Next up I think I want to try whistle (strobe will be last if ever as I hear it can be difficult to dial in, avoid CATO, etc...) First simple question - I have whistle tooling (4oz.) Do I need to press a nozzle for a whistle motor with whistle tooling? I also have 3/4" 1# hybrid tooling I believe can make whistle motors, but again would it need a nozzle? Would the comp need any adjustments due to tooling not being "true" whistle tooling? I figure I'd start with a potassium benzoate comp as I've made it before into a whistling-pete fountain, and it was very loud! (and an aside...end burner vs core-burner. all things being optimized for each construction (hottest comp core-burn can take w/o popping; 75-15-10 ball-milled BP with eastern red cedar charcoal. Which rocket flies higher? end-burner or core-burner?) Thanks! Link to comment Share on other sites More sharing options...
Zumber Posted March 28 Share Posted March 28 Whistle is extremely powderful and sensitive mixture. You must not even screen it with sieve you will need paraffin oil/ mineral oil to reduce its sensitivity while mixing and pressing. Also needs personal protective screen or remote press to press whistle. And whistle needs no nozzle at all.....it is nozzleless.. Link to comment Share on other sites More sharing options...
