Aluminum for shims?

(1/3) > >>

DeaconKC:
Picked up an older Crescent SxS this weekend. It is a bit loose, so I need to shim it. I do not have my brass material [disappeared in our move], can I use aluminum instead?

Sir Charles deMouton-Black:
I have used brass salvaged from pistol cases to shim tang site bases. They are slightly tapered, so you can orient them carefully to have a rough windage adjustment. .38 Spl have a gradual taper, while 9mm have a steeper taper. Cut'n try.

P.S; to answer you real question, why not? It is a bit softer than brass, and might not stand up to extreme stress. Aluminum comes in different hardnesses, so try it. Pop can material?

DeaconKC:
Not for a sight, that would be an easy yes. It is for the hinge area that has loosened over the years.

Sir Charles deMouton-Black:
It just occurred to me. I have a role of foil that I used to "beagle" a bullet mold. I am away from my shop, but I seem to recal ithad an adhesive side?
