StratoFins Water Rocket, Assembly Part 2

Before assembling I sanded off any printing on the PVC tubes.

You don't have to do this, I just wanted the launcher to look cleaner.

Nine of the cable wraps are used on the release ring.
Line up the tops with a straight edge, the flat sides are down.

For now it helps to hold these in place with a piece of masking tape.

A 5" long piece of duct tape is set over the ties, 4 1/2" down from the top.
Don't tack the tape on your work surface, just stick it to the ties underneath.

Lift up the cable tie assembly and turn it over.
Apply another 5" piece of duct tape directly over the top of the first piece of duct tape.
This is set down sticky side to sticky side.
Set it down carefully, it will stick quickly and very strong.

Press a fingernail between the strips making trenches between the strips.
