Supplies and Tools
Step 1. Predrill a hole in the post of the casting.
Drill a hole in the post of the casting, using a 1/16″ drill bit, that is than 3/16″ deep.
Make sure you are at a 90 angle to the post. The post is small so there is very little room for error. Also, be careful not to drill to deep and go right trough the casting.
Step 2. Add threads to the hole using a tap.
Using a 2-56 tap, screw the tap into the hole that you made in step one. The tap will cut into the walls of the predrilled hole making treads for your screw. Work the tap in and out, cutting a little deeper each time if necessary.
Step 3. Assemble the casting with a screw.
Now you can reassemble the casting and using a 2-56 X 3/16″ screw.
Do not over tighten the screw, the metal of the casting is very soft.
