First please let me say hi to everyone and thank you all for everything I have learnt from your knowledge on here. I have been in and out of pyro for many years as time is available. I have made very consistant bp of various grades prefected over several years of experimenatation. I used to be interested in model rocketry and would like to ret makng my owm motors.

After being let down with a tool I have decided to take to my lathe and make my own. Could any body help me with any technical dimesions needed plese. I would be looking to make a 12mm one to start and maybe up from there if thats successful. I will need to know my nozzle size and depth and how tall it should be. Does it need any taper on it. I know there is a science to all this but a start point will help. I have read several articles but want to be sure before making swarf.
Thanks Again Dale
