Properly sized pins help eliminate the need for taping to prevent lines or flesh from snagging. Fortunatly you'll usually have the right sizes in new gear. The pins should all fit exactly, especially not too long, so that the cotter pin lies nice and flush with the jaw. The cotter pin itself should fit closely in its hole and be short enough that when you bend the long leg just a bit, neither sharp point sticks out. Finally, the screws are most nicely held if you use Brion's dodge of welding rod.
G'luck
