I am in need of help this week. I know this may seem like common knowledge to all of you but I must ask that you please spread this knowledge on to others.
When browning a lock (i.e. rusting metal parts) please make sure that you take the lock completely apart and brown each piece individually. Reasoning being if you brown the lock fully assembled with all the screws in place and parts touching each other a bad, bad thing happens - all the parts and screws rust together and you can no longer get the lock to function nor any of the screws to come out. It's funny how rust has a binding affect on moving parts.
The only way to save a lock after this has been done is to carefully drill out each screw and replace them with new ones. The top jaw screw must be cut out and replaced. Then sand blast the parts that must have a smooth bearing surface and re-polish them. Finally a heavily layer of grease must be applied to all the working parts.
So please pass along this information to anyone who you know that might ever contemplate browning a lock. It sure will save them lots of headaches in the future, and also save them the cleaning fee we are now implementing for locks that get returned to us for repairs in this condition.
Thank you all for your help!
