At the other end, we similarly drilled out the end cap to allow the steel rod to pass. Here we're using an off-the-shelf length of threaded rod, as getting a sufficient length of smooth rod delivered and threaded at one end was going to take weeks. We just inserted the rod into a rubber tube, to prevent it snagging as it passes through the PVC end cap.

In case you're wondering, the 4mm steel rod seen in the component snap above is just 15cm long - not enough for our purposes.

So, with the oxygen tube sealed at both ends, we could now conduct a high-tech pressure test...

...which demonstrated just how much the tube can expand:

Of course, we tested the assembly for leaks, in the time-honoured fashion:

Finally, we put the whole thing together and mounted it on a test base:

It just remains to see how this performs at altitude, as we'll be bringing you the result in due course. For the record, the downside of this simple yet elegant set-up is that the PVC tube alone is 60cm long, and of course the steel rod is seen here in the "fully compressed" position.

This extravagant dimension will impact on the size of the main payload box, but we think we can use this to our advantage, as you'll see in due course. ®
