Star-made shell plates
« on: October 23, 2017, 10:11:51 PM »
On original #13 Shell Plates produced by SMW, was any form of surface treatment [for rust prevention or aesthetics, not related to hardening] applied prior to the front and back faces being ground & polished?
Hot bluing, black oxide, other metallic coating, bead blasted, etc.?

Greetings,

I have seen two style of shell plates.

The old original ones appear to have been sand blasted prior to grinding. This would remove any "crud" from the heat treatment and also gives the plate a nice visual appearance.

Toward the end of Star's reign in San Diego, and perhaps with the Pioneer owners, I have a plate that still retained the black appearance from the heat treatment. It was never sand blasted as the old ones.

Does this address your question?

Cheers,

Dave

Yes, thanks Dave.

That explains the textured appearance of small recessed area around the center hole on the bottom face.

When cleaning up acquired used parts that have some surface rust, I usually throw them into a container of Evapo-Rust.  It removes rust and any other oxide present (like bluing).  I was wondering if I was removing any SMW applied surface treatment that would have been left around the shell holder cuts, the center recess on the bottom, and the outside edge. Apparently, there is none.

Thanks again for the response.

I have one 45 Auto Rim shell plate that is blued.  It looks to be original Star, but I have no idea if the bluing was done by Star, or at a later time.

The Dillon 223 SuperStar shell plates were blued.
