Just a quick walk through.
Use a Sierra kit. Only one tube, quick and easy to make.
1) cut a bunch of blanks to approx. length.
2) drill blanks
3) glue in tubes
4) mill ends
5) turn
6) finish
If you can't do 100 of 1 and 2 inside of an hour, something is wrong. glue up may take another hour, and by the time you get to the last, the first should be ready to mill. Milling another hour tops. Turning with a carbide tipped tool can go pretty quick. And finishing with friction finish is very quick.
So I really think 100 per day per person is possible. If done on the quick and easy path, not necessarily quality.
