I just have easy acsess to malleable iron and in lots of sizes and I want to make a hybrid out of it and I would like it to be safer than useing sch80 pvc but is it

Yes, it will be fine. Didn't you just post a topic like this?

yes it is almost certainly safer then pvc, i posted a few day ago about some malleable iron fittings.

No that topic was for sch40 steel not malleable iron.
And Im very glad to hear its safe I will be starting my hybrid when summer comes along

why wait till the summer? i would get going so that i could take my time and think it over properly.

Because by then I would of save up some money and because my dad says I can make one when Im 15 which is at the start of summer

ahh cool i'm 15 i was on the 3rd december and i also have to save up for all my cannons but it gives me time to perfect the design

here is a link that should help you since you are obviously tryng to learn about pipe pressures and different pipes.

Thanks so much for the link grumpy that will help so much with the hybrid

What is DDT?Ive always wondered that. Ive checked the spud wiki and it just doesnt make sense to me.And 2000psi minimum burst pressure thats wonderful

Deflagration to Detonation Transition.

Bad if your a average spudder, good if you have one helluva strong chamber and want to break the sound barrier.

More or less the shockwave from the flame front travelling faster then the speed of sound is too strong for the pipe to handle and it fails.... I think.

I think I get it
But how can I avoid this from happening

On the other hand, after a small spark has created a deflagration, the transition process can take several meters or longer and a corresponding large amount of time. The key to detonation initiation schemes applicable topulse detonation engines is to significantly shorten the distance and time required for deflagration-to-deto-nation transition.

Deflagration-to-detonation transition is the general process by which a subsonic combustion wave(deflagration or flame) becomes a supersonic combustion wave (detonation

So I guess that means, don't have too long of a chamber (like a few meters long.)

I'm not the best person to talk to about this, I more or less have picked it up from reading other posts, you need someone like BoilingLeadBath, DIY or SpudBlaster15

Do you seriouslyexpect me to read all that. I started it and then noticed how long it is
