Picture-Frame Marking Fixture

Is Adjustable

W

HENI HAD TOmake a large number of hardwood picture
frames, I designed this fixture to help me mark out miter lines
on the frame stock. The fixture, which adjusts to fit the artwork you’re
framing, consists of an aluminum yardstick and two shop-built sliding
blocks. Each is equipped with a thumbscrew for locking a 45 ̊ thin-
plywood triangle to mark the miters and a replaceable filler strip cut
to fit the rabbet in the frame. It’s important to align the edge of the
triangle over the corner of the block below for proper registration.
To use, adjust the sliding blocks to touch each edge of the artwork,
and lock the blocks into position with the thumbscrews. Place the
frame stock in the jig, so the rabbet fits over the filler strip, and adjust
the stock position until you have the grain pattern you want. Now
mark the miter line on both ends of the frame by scribing against
the triangle.
