Hello everyone. Im currently well out of the pyrotechnics and have been for months as im pursuing bigger interests (believe it or not!) in life. Pyrotubes4europe.com ran out of webspace and some tw@t bought the web name before i could re-new so thats why it never started back up, plus tube prices were high and damand low. Would never make me rich lol.
Anyway iv got about 200 - 36" x 1" id tubes left, parallel wound with 7mm wall thickness, very strong.
Also got a couple hundred 1/4" x 8" id tubes, parallel wound with 2-3mm walls, also very strong and handy for all sorts.
Il sell the LOT for 200 quid plus what ever postage comes to (would probs be around 45 quid) , or collect from Middlesbrough. Thats less than 50p a tube!
If your interested in the lot of just 20 or so let me know by PM. If not il prob just re-cycle them all and get rid coz their just in the way in the unit.

I think a 2inch core might be ok but could lead to a cato..would make them even more powerful if it never cato'd. The main reason i make them end burners is because i am only filling the top of the tube off with 5 grams of flash so they aint carrying anything too heavy and dont need the higher thrust of core burners. The tubes i have had good success with are 5 inches long and use a 2ft green garden cane for the stick, could do with being 3ft but aint got any longer ones left..they work ok with a 2ft stick though.

Im sure a 3lb core burner could lift a 6inch shell easy. End burners - not sure but at a guess 4" maybe 5. Il have to get some more scales to do a test on the thrust of these big mothers got over a kilo of initial thrust using the 3/4 inch tubes (possitive i can get more though) so the 1"ers i think it will be more like 1.7-2kg initial thrust.
Theres not much point buying a tool for making an end burning rocket bit of a waste in my eyes all you need is a wooden dowel and a drill..thats what i use and they are perfect.
Sound like some very good rockets you made shame about no vids ya gota love a good home made rocket video. Its fun testing and experimenting rockets but nothing beats it when you have em shooting of like a bullet every time with no cato's or upside down fountains lol.

I can imagine what that would have looked like in person very impressive rocket for a 1/2 incher!
Yea.. i use a 5mm hole with a meal based comp but slowed down with unmilled BP. And here is the vid i said i would make, same problem with camera quality but you get the idea..listen to the roar of this 1" end burner:)
PS off to make some more:) lol
