Editing Guide to Assembling Models (section)

=== Pinning ===
If your model is metal and has large parts, you'll want a stronger bond than mere glue. '''Pinning''' a join requires drilling two holes, one in each of the opposing faces of the join, and inserting a metal rod (such as a length of paperclip) into both holes to bridge the two parts. This rod, called a '''pin''' reinforces the join. Inserting a small amount of superglue into both holes is encouraged, to secure the pin. It will support the weight of any parts that might scoff at mere glue and think about breaking apart the rest of the finished model.

Pins can also be useful for making tiny or fragile plastic parts much more durable, a common issue with dynamically-posed [[GW]] showpiece models. If one carefully drills a hole through a frail plastic element (such as the ankle of an outstretched leg), inserts a pin slightly too short to fill the hole, and smooths over the hole opening with green stuff, a part which is liable to break in the future may become the strongest point on your model.
