2 gardena nozzles: 9 mm and 20 mm

[RaZias]

I think this nozzle is posted somewhere but I finded another nozzle size

The black one has a 20mm diameter nozzle and almost 5 cm height.

The package from the black one says:

BIG
G.F.srl
CORREGIO (RE) Italy
made in Italy
cod.3352-5434
8000.5434

I also bought the component that attatch the nozzle to the garden tube, it´s quite big and has less friction compared to the Gardena.

If someone wants to try different nozzle size it could glue something inside the big nozzle to reduce it´s diameter, so it would be between 9 and 20 mm

Jinkies! Thats a huge gardena. I have to find one for my wrockets! You guys are a wealth of information lately. More than usual! ;-)

Hi,

WOW! Now we only need to find quick disconnects for "A" and "B" fire hoses....

But how do you connect these beasts with bottles?

And is there a chance that you will also post pictures of the female counterpart? I like pictures of females, if they look nice.

Regards
Soren

To connect the big nozzle to the bottle:

1º-Melt the screw zone of the bottle with a hot metal (a knife or whatever)
until it stays almost perfectly cilindric

2º-erose the remains with a steel file tool

3º-put the nozzle by forced rotation until it fits

4º-remove the nozzle, put glue in the bottle area and re-insert the nozzle

Where is the quick release for the 20 mm nozzle

By the way how much pressure can hold a plastic quick release ?

That's huge! Wow!

[RaZias]

Where it´s mounted in a 2 L Pepsi bottle.
The tap-adaptor that cames with the nozzle it´s glued to the melted the bottle´s screw-zone. ( I hope my glue resists the pressure...)

At left it´s a 2 L Cola bottle with a 9 mm nozzle and main chamber reinforced with very large zips (I still didn´t tested it´s max pressure).

Sorry for the size of the picture...sometimes I resize it badly...

[RaZias]

I think I have found another trademark that sells these nozzles and quick releases

Check out the site

http://www.semperflorens.ro/3501.htm

You can see a nozzle for 5/8 and other for 3/4 hoses.
(don´t get mistaken by the size of the picture)

I saw the IPIERRE GARDEN in the same shop I bought the G.F. but it looks that somebody buyed all the IPIERRE...maybe cheaper ?

The trademarks "G.F." and " IPIERRE GARDEN " have their sites under construction so it´s necessary to check on-line shop that sell these components.

Anyway I also saw a metal quick-release for 15mm nozzle.

Have you done any testing on the zip-tie reinforced bottle? I read you haven't tested for max pressure but have you tested it to see if it goes any higher than a regular bottle? It looks really super strong the way you have it reinforced.

Well I am having air escape in my launch system so it´s hard to pass from 85 psi, I will re-built a launcher more air tight and with a stronger hose.
Anyway I only have a 140 psi compressor.

But I belive it can hold more pressure than the non-zipped because I couldn´t see the expansion of the bottle as clearly as the non-zipped version.

Comparing the rocket at same pressure (85 psi) with and without zips the " zipped rocket " goes less high do to the weight (you really can fell if when you pick it) and is more instable in the air (anyway I have to re-design the CP and CG).

If you wanna have the idea of the heigt well...it sounded like a piece of wood when it hitted the ground. (where it goes down...PUM)

I glued something (the black ring on the top) because at the beggining due to expansion the zipps started to slide letting space betwen them.
(don´t know why they didn´t slided down...)

The ring is made of a black tape glued to the bottle and a soft tissue glued to that. And a black tape covering the tissue.

The zipes measures almost 42 cm and I alterneted the zip-head for each side.
I buyed it at the chinese (the trademark is " BlueSky ")

Do you think you need so many zips? A smaller number of zips with an even space of empty gap in the distance between them would stop the bottle from growing diameterwise in the same way and would yet be less increased in mass?

[RaZias]

The fact of having so many zips it´s the fact that stops the spacing between them when the bottle diameter stars to rize.

If there was some space at the beggining then at the end it would have some centimeters between them.
That was what happened in my first zipped-rocket.

Belive me they aren´t so "many zips" they are the " necessary ones ".

But to know who is right it would be necessary to test the max pressure of a simple bottle, a full-zipped one and a "more or less zipped one".

Just when I have finished builting my launcher more air-tigh I will comprove that.

[RaZias]

Where is the same bottles but in another perspective.

( I really start to think that this topic should be in the thread about " zip reinforcement " since it´s an off-topic)

Hi

wow that nozzle is huge!
do you know if you can buy it in the uk?

Thanks

I bought it in a shop in my country (Portugal), so I don´t know if they are sold in UK.
I posted in this tread the specifications of the product (trademark etc...) as well of another trademark that has big nozzles.
It´s from an Italian company.

There is only a slight problem with the female part, it needs to very (an very) tightened to the house so the air won´t scape.
Now I am using a metalic component to tight the house to the female part.
