Lovely! I especially like the delrin glowing red when it fires

These threads should give you a good amount of info:

I had an idea a long time ago about using a certain type of candy as shot.

Why not shoot one of those enormous jaw breakers?

Can you use regular compressed air as the oxidiser for a hybrid rocket?

would there be no worries using meths n an oil burner design? Like this for example : http://www.backyardmetalcasting.com/oilburners09.html

or a design where pressurised air pushes the fuel though the atomiser nozzle

Id be worried about the high ...

I just wanted to use it as a quick test bed, since building a mini copper mono tube boiler would cost an arm and a leg at the moment. As for heat I would use a vaporising alcohol burner. :D

i think it would be best though to pass a hot flame underneath the radiator, so that the hot gases would ...

oh, I cant find a video of the particular episode, care to post a link?

thanks

Just wondering if this could be used as a steam boiler.

Water would be fed in, and the heating source ...

Could my design work with a <70% spirits? I happen to have a few litres on hand. Besides I doubt I could get sunflower oil to run with this design, especially at a small diameter.

besides my tyre compressor is very small and can only deliver about 8cfm IIRC.

A burn tube would be a piece of steel or copper that sits on top on the fuel nozzle and is preheated before lighting?

And yes I would hopefully like to get this design to work with sunflower oil or similar.

Id like to use an oil burner for various hobbies that I do , but I need it to be very compact, and so I drew up this (very crude) design. Hopefully you get the design, as it works similar to aerosol cans in the way that the air pushes the fuel up the nozzle, mixing with it as the flow is restricted ...

Is not so heavy, 200g

Thats still fairly heavy, and with a bullet that looks about an inch in diameter, I think you will find the performance quite disappointing, due to such a dense bullet and the use of a very fast burning gas. Although I would think that a normal combustion would have some ...

edit down your posts a little to keep the intended use a little more vague.

Good point, posts edited

Is there a reason you don't want to use a combustion?

its not quite as precise as using air, plus I already have most of the fittings for a pneumatic on hand so the cost would be reduced. But ...

Well they cant be discussed, mostly so that people don't replicate the recipe and injure themselves and the fact that this isn't that type of forum, so that's why i haven't mentioned what it is or anything about it but its obvious what it is to most people on this forum.

My only concern with your ...

My "magic dust" worked brilliantly when tested yesterday, I would like to build a simple mortar to launch this high into the air.

I don't want to rely on something like a lifting powder so I thought a pneumatic would be best?

I would need to fire "object" about an inch in diameter and I can use ...
