There is a lot going on in this photo.  The top left shows the approximate length of the shaft you need to
keep the film cannister from being forced forward when the charge goes off.

The centrifuge vial is at the lower left and a Daveyfire 28B is threaded through it.  The Daveyfire lead is
threaded through the film cannister in which I've drilled a hole just big enough for the lead.

The Daveyfire is wired to the terminal block on the GWiz.  In order to fit the GWiz in place I removed the
standoffs and saved them for use in other payload sections.

Also shown is another bit of foam.
