Look up CA954 aluminum bronze.
Very good sliding surface on stainless.

I have brass contact fingers and they work well.
I'll get a brass bar yet tonight then, thanks.
When supporting the
barrel tennon, they ride on the threads without damaging them.
Threads on a p-17 are square, 10 tpi. I already have a tool ground for
that.
Otherwise, they will always leave an annoying ring on a barrel. Only
way to circumvent is to make a collar to slip over barrel, then skim
cut concentric with the bore. Other option is to make a set of
inboard and outboard cat-heads so you can work near the head stock.
This really depends on the spindle bore dia and barrel dimensions you
are working with.
Fortunately, the spindle will pass the barrel nicely all the way.
It looks like I'll have to make the spider bolts, so I may as well get a
foot of 1/2" brass hex stock while I'm at it.
Currently working on a piece of 3/4" steel, crooked as a dogs hind leg,
need to fit the action on it between centers so I can face it square.
But first I had to shim the tailstock for elevation, it was about 25
thou low.
Then figure out a way to spin the bolt as its face is about 3.5 thou out
of square. Thats hard on brass. Then measuring the tenon after getting
it out, it doesn't match the drawing I have by as much as 37 thou in one
measurement. And I need to make a headspace gauge as I've not managed
to find one for the 6.5 C.M. Yet. Lots of work before I actually chuck
up the barrel.
And I found today, that the scroll in this 3 jaw chuck is an absolute
piece of crap. So I am tightening it, measuring the runnout, loosening
the mount bolts and tapping it gently to make it run true at the size
its currently tightened on. This chuck, a Polish Bison that looks brand
new, must be a very poor factory second to be that far off. I already
cut the registration in the backplate down some so I could move it
around.
Honeydo's call. :)

Thanks Marshal.

Greetings all;
My steady rest has steel sliders, which will not do for working on
finished parts. So I need to order a foot of 1/2x1" brass or copper
to make some more better shoes.
Which will do the least damage to a pre-finished part, such as the
fairly high polished SS barrel? Brass or copper?
Thanks everybody.
Cheers, Gene Heskett
