Description: |
|
Here's a real gadget. Not only can this gage mark off bevelled
edges, it has an flexible fence to follow any curved edge,
bevelled or straight!
The pivoting design is here is pretty unusual, in that it uses a
split rod with the pivot point for the head running in this
slot. This means that tightening a single screw will lock both
the angle of the head and its position. This is quite a clever
idea-- it seems like it would hold well, but would probably be
a pain to adjust.
This gage also is the first to sport a flexible fence, which can
be adjusted to match the curvature of the reference edge. It
works much like a typical metal compass plane, using a flexible
steel plate attached to adjustment screws at the edge.
