Hand Made Piercing Saw

[75Plus]

The thread Chris posted reminded me of a piercing saw that I have. It was made by a friend's grandfather while he was learning tool and die making on the G.I. Bill after WWII.

The saw is made up of 14 pieces, only on 5 of them factory made. These 5 are the 4 socket head cap screws and the cast ali handle. Currently one of the collets that holds the blade is broken and I haven't taken the time to make a new one. From the appearance of the break it was due to the heat treatment leaving it brittle.

Should anyone want to duplicate this saw I can furnish dimensions and improved photos.

Here is the saw.

Joe,

How is a piercing saw used? I think I know, but I am not 100% sure,

Eric,

Piercing saw is just another name for a jewelers saw. It is a bit of a misnomer as it doesn't 'pierce' anything. It is put to use AFTER a hole is drilled. old_biker_uk's post in Craynerd's "Piercing Saws and Albra Files" has a link to some of his piercings.
