FTC Nozzle
Pretty frosty around here. It jut snowed ad this morning it was 3 degrees above zero! That is pretty cold for around here! I was wondering especially from anyone who has made and FTC rocket, I have made the nozzle out of the caps provided and used an X-Acto knife to cut a hole in it. This way I fit the neck of a soda bottle in here. The only problem is launching it. I can't find out how to launch it because the rim for the zip ties to hang on to is covered up with glue. It is a full bore rocket but I can't seem to figure how to hold it on during pressurization. Can anyone help?

Re: FTC Nozzle
Here is a picture. I will try to post another one later, as you can see this is not the clearest.

Re: FTC Nozzle
Yeah you are going to have to redo that. Unless you want to go to the trouble and building an internally gripping launch pad.

Re: FTC Nozzle
Yeah your right. I was thinking about a launch rod but I think the bottle i better. I'm just not sure if what I did will hold the pressure. For the end cap I used the FTC cap and PL'ed a bottle cap over the end and then glued the FTC cap in place. Will that hold. What do you guys do?

Re: FTC Nozzle
Threw away the cap that came with the tube. Heat shrunk a bottle over the bottom and top. Polycarbonate doesn't shrink the way blow molded PET does. Glued with PLP.Water Rocket Expert wrote:Yeah your right. I was thinking about a launch rod but I think the bottle i better. I'm just not sure if what I did will hold the pressure.

Re: FTC Nozzle
I didn't heat shrink it I just glued the edges to it I think it ain't gonna work so I will just have to try to do your method after I test it. How high should it go? It is about 6.5 feet tall excluding nose cone part, has a ring fin and it will be pressurized to 120 psi. How much higher can I pump it to since it is not reinforced? Maybe it will go 700'?

Re: FTC Nozzle
Someone else will have to answer that. I typically don't pressurize over 100psi.Water Rocket Expert wrote:I didn't heat shrink it I just glued the edges to it I think it ain't gonna work so I will just have to try to do your method after I test it.
