Tec tip--When replacing lock retainers sometimes there is not enough room to maneuver the retainers in place, and hold them on the proper position as the lock or mechanism is assembled.
If you will roll a tiny ball of heavy grease, and press it to the tip of a lock pick, you can stick the retainer to the pick and place it easily in the tightest quarters.
If you need to keep something on place, say ball detent or a tiny cam this will hold things in place, and act as a lubricant when you are done.
Tec tip 2--When installing a adams Rite type latch you can paint or put a arrow on the door, above the cyl with the proper rotation and print left or rigtht to open . This will stop call backs from some one turning the key the rong way.
