Bought a couple 6" chucks at auction that both need back plates in 1-1/2.
They were cheep and I thought the reversible jaws would be very handy.
The 4 jaw is a Union and is probably worth more than I paid for both.
It has a back plate but it appears to be 2-1/4. The back plate bolts all
the way thru the chuck with 4 x 3/8 bolts. The 3 jaw scroll only has 3 x 8mm
bolts out at the very edge - seems kinda lite to me especially if its going
into CI which some of the blanks are. The 4 jaw BP appears to be steel which
to my thinking makes more sense. soooo. . .
1. steel v. cast iron
2. pointers or pitfalls to look out for in fabing one
thanks to all that contribute
