 ## Results ##
 
-The batch size was pretty good, there was a bit of excess propellant in each
-batch so we can make density and burn rate measurements after cure.  The excess
-weighed in at g after cure.
-
-Grains were cut, core drilled to 0.625", and sanded more or less ala Terry's
-process.  In the data below, lengths are a bit approximate due to imperfectly
-squared ends, gross masses are precise using my new 600g by 0.01g scale!
