Fixed cleats for your modern 1/350th scale submarines.
If you've ever built the Hobby Boss 688 family of kits, you know how much of a pain it is to glue the plastic fixed cleats in place. This is 100 times easier.
You'll need a fine metal file, a small pair of strong nippers, a pin vise and micro drill bits and six shirt pins. Drill out the mounting holes on the hull using a 74 gauge/ 0.0225 drill bit. Using your pin vise handle, chuck up a shirt pin so its easier to work on. Cut two opposite sides of the head of the shirt pin so it starts to look like a US football. File and sand to get the final shape. Trim off the point of the shirt pin, leaving most of the pin intact.
Stick the pin in one of your drilled holes on the hull then add a dot glue to the pin before you position it, then paint.
Shirt pins have hundreds of uses in modeling, from adding strength to delicate/fiddly assemblies to adding antennas to model cars, you can even use the cleat trick to make a nifty removeable air cleaner on the engine of your model car.
