17. Spiral locks are a great upgrade to pressed-in pins but can be a real pain to install. Jeffery Stretch from Specialty Machine Inc. has a way to get these boogers in quickly without any special tools. First, use the tip of your finger to open up the end of the coil of the lock, then insert the tip into the groove. Now pull out your finger and use a flat tip screwdriver to push down on the coils with a smooth circular motion. When you get to the end with the screwdriver the lock will be completely installed into the groove.
