+# Test 1 #
+
+Trying again using the same formula as [test 1](test1.html), but different
+handling logistics for pouring the grains.
+
+[Tru-Core](http://www.rocketsaway.com/html/casting_sets.html)
+casting set with two bases each set up with 0.5 inch mandrels. Four pieces
+of casting tube cut to grain length of 1.875 inches.
+
+## Process ##
+
+The grains were cast on 31 May 2015.
+
+The multi-cooker was preheated to about 250F with the lid on. Temp was
+increased during melting to 275F indicated.
+
+When the 200g batch of propellant was nearly ready to pour, we put in enough
+bits from the void-plagued grains of test 1 to re-melt that we'd be able to
+cast 4 grains plus a burn rate test rod.
+
+We poured one grain at a time, leaving the multi-cooker heating and putting
+the lid back on between grains to keep the propellant at temperature. The
+first 3 grains poured pretty easily, the viscosity was higher when pouring
+the last grain so not clear how well it filled. Two grains stacked on each
+mandrel, for 4 grains total. That left enough to form a test burn rod about
+3/8" diameter and in excess of 4" long.
