Zmuro Posted December 20, 2016 Posted December 20, 2016 Pirotex, thanks for sharing your tools dimensions and maximum load capacity regarding fuel type used.
DavidF Posted December 20, 2016 Posted December 20, 2016 Yes, thanks! I notice that the BP spindle is quite long compared to what we use over here. It is very nice to see the tooling, formulas, details, and shells all together in one place. Thank you very much for doing all this work for us. Could you tell us about the fuel a little more? Is the potassium nitrate ballmilled to a fine powder for all fuels?
ExplosiveCoek Posted December 20, 2016 Posted December 20, 2016 Do you use QM to ignite your rockets?
Pirotex Posted December 20, 2016 Author Posted December 20, 2016 DavidF, all chemicals must be grinded and mixed very fine ExplosiveCoek, yes
mikeee Posted December 20, 2016 Posted December 20, 2016 The spindle geometry would also work with whistle fuel.
greenlight Posted December 21, 2016 Posted December 21, 2016 I have been looking for something like this even though I have an 8 oz rocket kit.Just tried the last fuel in section 2 for short motor in an 8 oz rocket with no heading and it had what seemed like very good thrust.Ball milled the chems for 20 mins together.Can't wait to try a heading when I get some hemispheres.
