oldspark Posted July 16, 2013 Posted July 16, 2013 Looks good, what kind of ball mill and media do you use.
yvariro Posted July 16, 2013 Posted July 16, 2013 HelloNice try I have bought my rocket tooling on oliverbrown too!,It do the same nozzle ID as your but my spindle is slightly longer,I've done few test,and the best fuel that work for me is 65-25-10 Because your spindle is slighltly shorter,you can try 66-24-10 or 67-23-10 with this ratio you will be able to lift 300-350 gr header with no problem I personnaly don't add mineral oil and any binder to the composition but that's up to you Good luck !
