I have for years, oiled shock resist jewels the old fashioned way. Place the oil on the freshly cleaned cap jewel, and then placing the hole jewel in its setting, over the oiled cap jewel. This works fine 80%+ of the time, but unless you are dead on when you place the hole jewel over the cap jewel, the pair end up not properly oiled. Of course that involves re-cleaning the pair and trying again.
I am wondering if anyone on the board (who believes in separating these jewels so they are cleaned properly), who successfully uses capillary oilers to lubricate the re-assembled jewels. Are there problems with residual oil ending up outside the hole jewel (within the hole jewel setting) as the capillary oiler is either inserted into the setting, or upon being extracted? Is it a totally satisfctory method compared to doing the old-fashioned way?
