Our resident metals expert wasn't at work today, so I didn't get to ask his opinion on the 1144 matl. We use tons of 4140, but I can't ever recall using 1144. I doubt either one will make a difference in this application.
Correction to my original post--I believe 6' of matl will only yield 3 shafts--thats 2 more than I need at the present time.

1144 is called stressproof. Not good for welding. Don’t know it’s strength offhand. It machines like a dream though!!
