Logan 200 lathe (over 70 years old)
4 jaw chuck
ER 40 and 3/4" collet
4140 PR hard
SASswaging instructions
My questions:
Can an ER 40 collet hold 12" bar with out a lot of harmonics, or does the bar need a tail spindle for support. or
Do I just chuck up a 2" piece of bar to the collet , square it , then drill the 1/8 hole all the way through and proceed with the other drilling and lapping to the tubing size, then thread the press end and flip the die and make the final cleaning?
