# Test 2019-3 #

Re-starting the process of characterizing "Everclear" now that we have a new
1600psi pressure sensor on the test stand.

This was a 2-grain 54mm Everclear motor using a #24 nozzle.  Ignition was 
with one of Terry's igniters, on Saturday at the Tripoli Colorado Spring 
Fling event near Hartsel.

The grains used were from the 21 May 2019 batch:

* 21 May grain 4
* 21 May grain 12 

Small profile o-rings were used between grains, leaving the grains still 
slightly "loose" in the case.  The buna-n o-rings on the nozzle and forward
closure were lightly greased, and the liner exterior was heavily greased.
