Impressive rocket mate, what composition did you use? Passfire worked well and lit the star, what headings are you going to use?

[ProfHawking]

Cheers! I was happy with it The nozzle on the tooling is bigger than i had been using before, so I used a hotter comp than standard RP, but not as fast as proper BP.
Using my cruddy & lumpish BBQ charcoal, 70:10:20 milled for ~ 3hr, I think its just about right.
I plan to use 2" canister heading for the 1/2" and maybe 3" ball for the 3/4". I will test them both to see how much they can lift.
I have some nice purple star comp mixed up, so i might try and use that. I need a star plate tho, my fingers nearly wore down making enough stars for a a few 3" ball shells with a srynge pump. I havent had enough of a go with rolling yet

Could somebody plz post the exact dimensions of a bought pyro tool set?
Tube ID, OD.
Clay plug angle (rammer).
Clay plug length.
BP core length, base with, top with.
I'll repport back to you when I've finished the replica.
PS. How strong is your press? I'm trying to replace my old one, it started leaking, and now I could'nt crush an egg with it. DS.

[ProfHawking]

i can do, as soon as i find my calipers.

as for my press, its 2 tonnes, but i broke it a while back. i rammed those rockets with a soft ended lump hammer.

I'd post a pic, but i don't have a camera.

basically i casted most of the bits, out of aluminium, used lots of pulleys and stuff, and a 500W motor.

[littlejohny]

you built a lathe I take it that its a wood lathe because I can't see a metal lathe being made in an average joes shed

[adamw]

Hey, respect if he really did make a lathe, wether it was a woodworking or metalworking one!

[Pieman]

does anyone know if Greg Boyd still sells tooling? that link doesn't work anymore.

[Pretty green flames]

This link should work http://www.pyrotooling.com/

Cheers for that i think the server must have been busy or something. I don't suppose anyone can send me the dimentions of a 1 pound rocket tooling set. I've started a new job as a lab tecnician in my old college (only temporary alas) and the physics department technician has a lathe in his prep room.
