Servicing the lock - to do - or not to do . . . that is the question !

[Rog]

Can't seem to find anything which tells how to service the locking system on any antique combination lock or door hinges, bolts and latch system.

I've taken a peek inside the back of the combination lock panel and can see where any previous grease had long since melted and run down the back of the panel.

Any thoughs on how to service these areas?

Also, I'm thinking I might rebuild my safe to include an extra drawer or two, and an extra pair of lock boxes - any idea where I might find the keys and locks for such items?

Thanks a bunch!
