Mark the location of the jig on the fence for future

reference.Then either clamp the jig, set the rail

end stop or hand hold the workpiece for cutting.

To easily obtain an accurate miter cut length, first

set your saw at the proper angle for your cut

(right or left) and set the Crown King jig on the

saw table, at the mark you previously made.

Place a piece of scrap molding into the jig and

make a test cut. With the piece still in the jig,

measure from the bottom of the jig to the cut

edge. This is the measurement you will need

to offset your final cuts.

Measuring the test cut – (Front view)

When making final cuts, extend your molding

(wall length) mark beyond the jig by this same

distance and cut the molding as shown. Repeat

the procedure when making cuts on the opposite

angle.

Then make the cut – (Rear view)

After cutting, test-fit moldings in place.

It’s as easy as that!
