He had a problem with his host, and basically lost his backups too. He is having to rebuild the site from the ground up.

I need some advice from the good folks here using Greg Boyd's BP rocket tooling. I recently bought both his 1/2" (4oz) & 3/4" (1lb) sets, and want to start pressing some core-burners. Just wondering how much nozzle clay and loading pressure to use as a good starting point? I know the BP fuel should be pressed to about 6500 PSI loading force, but I'm not sure where to start with the nozzles for both sizes of tooling.

Can someone help me decide what to buy?

Looking to buy some tooling but i dont know what i want, too small and i limit what i can do with it. What is a good size for a relative newbie?
Im leaning towards the 15mm (9/16 tube i think) which seems to be a good trade off.

As with most pyro, smaller sizes are better to start with. A 6 mm is too small for me so I would probably think 10 mm - ½ inch is a good place to start. You can always buy larger sizes and use them when you think you're ready.

Been making bottle rockets for a while, they work well but they cant carry a payload very high and space is limited. At $20 a pop for shipping its not cheap

[pudi.dk]

Well, in that case 15mm sounds reasonable.
I prefer to get my tooling custom made at my uncle though since that is cheaper. The only tool I'll buy is a crossette pump since those cannot be made on a lathe.

hi how would i go about makeing cheapo rocket tooling without buying myself a small lathe (drool drool) say i was makeing a 1/2" id rocket, could i not get a 1/2" thick walled tube and fix,glue,braze a smaller tubes inside until i get the correct size for the spindle somebody must of tried it ?

Well in fact a dowel made of brass, aluminium or wood and a dril is enough to make a rocket.
Roll a tube on the dowel and let dry. Once dry add clay, then BP, then clay. Drill a nozzle (be careful, safety!) and attach a stick.

Yoink.

Hi chris m.I made my own tooling,really easy.I put a 10mm Al rod in a electric drill,clamped it to my workbench and locked the power on,then shaped the Al with an angal grinder (PPE a must).It's a good idea to work out a few measurements on paper first to get core lengths etc. here's a pic of my 15mm tooling



Hope this helps
