I visited Estes Industries when I was a kid (in 1966), and remember the fantastic tour, including seeing Mabel cranking out engines. I also remember someone performing an operation on motors, and believe it was drilling out B14s. It was a long time ago, so I could be wrong. But, I am not sure why they would have to be drilled. Why not an automated process that has a pin that rises up into the nozzle prior to pressing the BP, and then is extracted, leaving a core?

I still have a few Estes B14s, and quite a few Centuri B14s, so I may try one of each this summer. I loved that motor as a kid! Only one problem I ever had -- I launched a Flying Jenny biplane glider with one, and it suffered major balsa disintegration.
