Description: |
|
The Bates Patent gage is the most famous of the gages designed to
mark off bevelled edges. It uses a head that can tilt up to about
45 degrees, as well as two fixed and one adjustable "gage lugs"
which can be used to register off curved surfaces.
The adjustable face on this gage works quite well, which explains
why these were so (relatively) popular. The adjustable lug for
marking curves is also a cool idea, but appears to have had one
big problem-- the adjustable lug was too easy to lose. You need
to completely remove the head in order to flip the bar over to
change from a bevel marker to a curved edge marker, which left
the adjustable lug loose. It is almost always found missing on
old examples.
