I just completed the mid-bulkhead, pictured in the middle above. That's the last of the major components for the Minisshot motor. There is still a lot to do, not the least of which is to tap the 102 screw holes. It feels good to have the major metal cutting completed though. The next major milestone in my mind is putting all the components together for the first time and seeing how it all fits together. I wonder what the motor assembly time is going to be with all those screws?
