I don't have the capability of making metal ones

Haha don't worry my man

I got you covered

Been developing carbon/metal composed adhesive composites for non machinable SRMs

And 3D printed mandrels

But the last test I did was a PVC engine (3/4) but I capped the end, then packed with clay, then fuel, then clay, then cap again. Drilled the nozzel through the cap and clay

It was a flying IED

No recovery charge

I make rockets out of pool noodles and anything laying around, so I don't care if I lose it, although that's not preferable

I don't recommend PVC

Have you seen what it did to a lot of rocketers

It's X-ray transparent

So shrapnel wounds meant they can't get em all out at the ER

I normally wrap them so if they should explode they won't send shrapnel everywhere

I was teaching my nephew how to make them

This is from last year

It's just a powdered fuel... Not solid

Wow that flew really high

Yeah, my powder engines work well, but I want that lift sucka

Ammonium perchlorate

And aluminum poweder

Almost double the impulse

This was the most recent failure

Lol

The flying IED

If the nozzel had been a little larger probs would have been fine. It was also top heavy, hence, the flying left after it took off

But that was just a test

Once I get it right, it will have a lot of lift

Dang you should really use a electric ignition system

Yeah, whatevs lol

I like the old fashioned fuse or even a sparkler

Lol

If you need help building one I can help, I literally do all pyrotechnics behind a blast sheild

I have an electric igniter, but I need to get plugs and the little wires

Unless they can be made

Yes they can be made

You just need nichrome wire and matches

I use 3D printed plugs, but tape can work too
