My Watchmakers "Staking Outfit" contains 120 Punches and 30 Stakes ( anvils). Made long ago, by a company called Boley Leinen.
Here is a list of some of the uses of a staking outfit.
Riveting, Jewelling, Hand fitting, Bushing Clocks and Watches, Reaming, Fitting Banance Staffs, Closing and opening Holes, Thread Making and punching pins out of Bracelets. This tool is so versatile that is can be adapted for many other uses.
If you are considering buying an out fit, then look for one that has a raised conversion table. This enables you to convert a Punch into a Stake, which vastly increases the outfits versatility.
The smaller outfits on sale with few Stakes and Punches are of limited use.
The reason for using an Staking Outfit is that the pressure applied to the job is equal and between centres. Very important when fitting a new balance Staff, for example.
Hope this helps.
