Improvements for this? The capital expenditure for any of it never pays
off,
so just forget about it.

Not necessarilly ... no one said you had to invest money to get access to
improved production equipment. Perhaps the production of parts needs to be
subcontracted to someone who has already invested the money in the
equipment
for other reasons.

US labor for those types of machines is running $35-$45/hour. Then there's
material cost, machine costs, and profit. Even the simply constructed high
production rate composite cylinders remain very expensive. I think it's a
great idea conceptually, but prohibitively expensive practice. Aircraft fit
and finish at any level is very hands on.
