Hi,

I just bought a 6" 4 Jaw independent chuck for my Myford ML7, but I
can't get a backplate around here. What steel would you suggest I use
to make one? I was thinking along the lines of 4140, but if 1045 is
alright, it's easier to get here... Any ideas?

I currently fabricating a backplate
for a 5C collet chuck from a cast iron
round.
