Postwar F3 Shell repair help

A split soda straw, some JB quick and some car wax on the screw threads will do the trick.

Fit the straw over the broken post, fill everything with JB quick, put in the screw with the threads waxed, and let the epoxy harden. When it is cured, remove the screw and clean up any excess epoxy.

When you put the screw back in, turn it backwards until it clicks, to make sure that you are using the original threads instead of cutting new ones in the epoxy.

I've done numerous repairs on broken posts.  Cut a straw and use it for a mold then fill it up with JB Weld.  After it sets simply drill out the hole.  Depending upon the size of the screw you'll have to use a numbered drill to get the right size.  Any good tool store will have numbered drills.  I don't have access to my charts right now or I'd tell you what size drill to use.  I am sure someone will chime in with the proper drill size.  I presume you are going to use self-tapping screws.

Thank you both.  I'll pick up some JB and let you know how it turns out.
