Complex metal models often need pinning.
This article will show how pinning can help.

To pin a small model you need the following tools.
A pin vice with 1mm drill bits, or a powered screwdriver or a Dremel tool.
A hex mount chuck if you use the powered screwdriver.
Paper clips to cut up for pins.
Pliers to cut the paper clips.
Araldite or equivalent two-part epoxy cement.
Blu-
tac.
If you need to assemble an arm, you drill a hole in the shoulder and stick a short piece of pin in it. Then drill a corresponding hole in the arm. Then cement the three pieces together with Araldite.
Since it does not stick instantly, you use the Blu-
tac to hold the pieces in position. Position the Blu-
tac away from the cemented joint as it will stick to the cement.
Araldite Rapid cures hard in about 15 minutes, and to full strength overnight.
You can also use Superglue with pinning, though it tends to crack off more easily than epoxy cement.
