Hey gorge I just thought of what would happen if u made the tornado coupler by to bottle caps and u weld them to gather then drill the insides out in please try this

@fatpeople249er This indeed has been tried before. Dan from British Water Rockets has had some good success heat welding the caps together to make Tornado tubes.

George ... at 14:26, you show a fairing that goes between the two spliced pairs. I tried that using the longest section of a single 2L bottle and it was not long enough. In the video, it looked like you spliced two sections together for the fairing. Could give some more detail on how you did that and what measurement you used to determine the final length of the fairing? Thanks!

@MrTomcarnahan The fairing is just made of two bottle sections that overlap about 1cm. You don't need a lot of PL for this. I assemble them on a cardboard tube to keep them aligned. The length I worked out by trial and error. I just kept cutting sections off until it was the right size. We have different lengths depending on type of bottles and whether they have reinforcing or not. You want the fairing to be tight when you tighten the bottles in the coupling.

George ... maybe I missed it but I thought somewhere you mentioned how you keep PL Premium from hardening in the nozzle. I used my tube of PL Premium once, covered the tip with aluminum foil using a rubber band to keep it tight. When I came back a month later, the PL Premium had formed a rock hard plug in the nozzle that I had to carefully drill out to use the remaining glue.

Can you recommend a better way so that the glue does not harden in the tip?

@MrTomcarnahan I always use a thick nail that I insert into the cartridge nozzle. The diameter of the nail is slightly bigger than the hole I make in the nozzle, so that when you force it in it seals around the edges. You normally have to use pliers to remove it again, but the nail leaves a nice channel inside the nozzle for the PL to come out.

where do you get a tornado tube

@sethdenzak I'll have to give that a try ... thanks!
