What i said then I'll say again now...we have a need for PORT/CORE burning E and F BP SU motors like the old Mini-MAX Centuri offerings. End-burners...meh.
*Tosses head in assent* Yes, and with today's 3D printing technology (which also facilitates precision, fully-automated machining and drilling of work pieces), safety is a non-issue for making B14, C5, and larger port-burning black powder motors. Also, new-production B8 port-burning motors could, like the original ones, be made using the elongated pintle (non-drilled) but otherwise standard pressing method. (If memory serves, the longer B8 pintles sometimes bent--or at least temporarily deflected under load--resulting in a defective motor, but with today's ready availability of much harder specialty metals [and alloys], stiffer yet spark-free pintles could be made.)
