If it helps ,

 

I mill the Kno3 and sulphur until super fine , i then screen all the ingredients together through a 60 mesh screen about four times and use .

 

I used to do this and in fact I wasn't too fussy about the charcoal. It came "air float" but also contained some much larger particles. They worked like a charm. It was when I started ricing the same comp that things got a bit variable.

I quite like the short mill for my tests as it really ensures the BP is reliably well integrated. It's no bother throwing a batch in the mill for an hour. Once I have a number of reliable tests under my belt I may change things a little, like this.

Ok things are going well. I am very happy with all the improvements to the build process, especially waxing the tubes!

Another 2 good solid tests tonight, still no headers but I've never had 60:30:10 milled powder work even in parallel wound tubes. They sure do seem to shift too so I'm dying to see what sort of header they will lift. I hope they will manage a 150g - 200g header up to a workable display height.

Good to read that you are getting on top of things now and are getting reliable motors  :)

Glad you're making good progress. Have you tried any nozzleless yet?
