Making the Displacer Pushrod & Creating the Pressure Chamber

We used music wire bent at a 90º angle and a quick drying apoxy to create the pushrod. We then placed the displacer and pushrod into the bottom chamber and stuck the wire through a hole in the upper part of the pressure chamber. We pushed the two halves together, and then cut a hole out of the upper pressure chamber, which was made easier by using smaller angled scissors.
