HI! Do you know steve laduke's universal rocket tooling? I have searched the dimension on the internet without any results! Do someone know the dimensions of 1LB rocket tooling?thx to all!!

You can ask him personally on passfire.com .

Yes I know, but I need to pay for log in in passfire :)

I asked this question hoping someone have bought this tooling :)

Maybe this helps

I believe he only makes rocket tooling with a max OD of 1 inch now.
If you send me your email address I can contact him for you, that is if you were intending to buy a tool from him and not just copy his design!

Hi guys! I had machined 1LB BP rocket tooling using ''pdfbq'' link. 2cm ID, spindle lenght 14cm. I've tested it using hotter 75 15 10 granulated BP without nozzle, ignited at the top of the core but the rocket CATO. Is the spindle too long? or is the BP too hot?
For UT tooling is too expensive to buy for me.This is the reason I have investigated for dimension.

Nozzleless motors are very hard to CATO so there might be something wrong elsewhere.
Your spindle specs don't look very unusual either, whats the diameter of the spindle?
Also, at what pressure did you press the motor and how large where your increments?

I belive the problem is the ignition because I made an electrical igniter using NC laquer with 75% BP. I tested it and it made a little BOOM, so i suppose it was too poweerfull. Is it possible? The diameter of the spindle is 1cm. I rammed the motor with increments of one teaspoon

Well then maybe you sorted this one yourself my friend
Press up another one and just fuse it with visco and see what happens.
Like I said, these are hard to CATO.

thanks guy! I have another question.. Do you can see the images and the other pages of this site?
There are many parametres to make 1LB nozzless BP rocket: http://www.angelfire...kets/index.html

Better check here...more info, and a lot more info about just about anything..

thx! It's a good website! As soon as I have some spare time, I'll try to make another 1LB motor! :)

HI all! I have another question for you! Reading AFN book I read some different contrasting things about rockets. On AFN II it is said that the nozzle is 1/4''(~ 1/3 I.D) with 5.5'' spindle lenght for 1 pound rocket. On AFN III it is said that the nozzle is 45-50%(~1/2 I.D) of tube for a generic rocket, which spindle lenght is 78% of motor. On website posted by sjeef1 it is said that nozzle is 1/3 I.D. Using http://www.flashnet.dk/rts/ the nozzle is 50% I.D.. So can someone tell me to make ''perfect'' rocket what is the best tooling design ? Using larger nozzle I should use hotter fuel right? or to reach highest height is better smaller nozzle with colder fuel or bigger nozzle with hotter fuel? Is reliable using(http://www.flashnet.dk/rts/) software? thanks to all. My tooling have this design:
I.D 2cm
spindle lenght 15,4 cm
spindle width 1cm
