Three New Splices Finally Finished

Veteran Fracture II Vessel serves as Strapping Tape Key
I finally got round to finishing three splices I had started almost the day after our last launch, all the splices have been pressure tested to 160PSI, 20PSI over there launch pressure and held there for 5 minutes before the pressure is released.
The New Three Splices

Two of these are going to be put to immediate use to make Stratum I (6.8 Litre Rocket) as mentioned in a previous post this will be our first rocket to use tornado couplings. More splices now however will be produced as spares and backups in case of a CATO  or Crash that may occur.

A Sneak Peak of Stratum III the Largest Rocket Planned to Date the Vessel Currently Stands at  224cm (7ft 4in)
Between me and the rest of the crew we have decided to not launch any of the Stratum assemblies until we have carried out a few further flights and feel comfortable with the Robinson coupled Nexus series.

Waiting to launch Stratum will also give us chance to give jet foaming a go, something we've been meaning to try since the assembly of Nexus I nearly 2 years ago!!

    The Stratum III looks like a very serious rocket Doug! :) What size nozzle will you use for that?

    Good to hear too about the pressure tests on the splices. Do you get any stress marks around the necks of the bottles at those pressures? Having spare ones made up is definitely a bonus.

    Looking forward to your next flight report. Keep up the great work :)

    Hey George,

    Thank you :) We aren't at all sure about the size of nozzle to use, but one thing we know for certain is the launch pad will need a little work to take larger nozzle's, the current release head will only take the 9mm nozzles or as we have tried in the past a 9mm bored out to 10.5mm(Didn't go well I'll see if I can find the picture). What release head do you use for your larger nozzles if you don't mind me asking?

    Regards Doug

    Sorry forgot to add I have currently had no stress marks at the necks but I'm sure I will see my fair share at some point :)

    Ahh good to hear that there are no stress marks. That means the reinforcing is working.

    We use the 15mm (maxiflow) release head and nozzles for the larger rockets. Just a lerger version of the Gardena connector. The 9mm is just too small for a large rocket. You can always also go with the full open neck of the bottle.

    Cheers
