Most bushings made at Kaiser were made of aluminum bronze (Ampco #18) like yellow hard steel not real fun to work with ---

Terrible stuff to machine. We made some parts from extruded flat bar. I recall squeaking just before the tap broke and corners breaking out at the end of a milling cut. The stuff of machinist's nightmares.
 
We repaired a lot of oilfield and mining equipment. Used this stuff on pumps mostly. Yuck, what obnoxious material to deal with.
 
I have plenty if anyone wants to give it a try.
 
I'm confused, I think Jeff just worked AL not aluminum bronze... right? wrong?

I've never worked Aluminum bronze either... is it hard, or just grabby?
 
Yeah, us old guys kind of ran off the topic rails….sorry..
 
Hard
 
Machined Ampco 18 and 45 way too many times!
 
Jeff,
I have done as John suggested quite a few times, making the parts back to back. Works very well. That lathe of yours will part that size aluminum like butter.
