Default Are there any tools to help cope crown molding?

Anyone seen any tools to help cope crown? Rockler has a plastic
device to help keep a jig saw at right angle and still sit on
something. Doesn't look like it would help much.....

Highland Hardware sells a coping foot that relaces the flat base of a
jig saw with a rounded piece. Looks like it would work good but
probably has a huge learning curve.

I'm only doing a single room and don't need a Copemaster or anything
that will take the entrie room's worth of molding to practice on.


A pencil, a coping saw, a utility knife, and a Dremel Moto Tool
(or a few small files/rasps).

I assume you are trying to get a good fit on an inside corner?

For that, put one piece in "square cut" so that it fits flush
against the wall. The second piece gets coped. Cut that
piece at a 45 degree angle. Use the side of the pencil lead
to mark the edge. Cope back along that line just a little more
than 45 degrees, careful not to overshoot the line. Then,
using a 1/2" diameter sanding drum on the Dremel, file
away as much as needed. Make the places where the
shape changes "perfect" with the knife.

Test your work, on the floor, against a scrap. When you've
"got it," then climb the ladder and put it in place.

Remember, ONLY the VISIBLE intersection of the two pieces
matters. The joint does NOT have to be good enough for
gluing.

"Piece of cake." After all, it's "only a single room" so you
only do this four times, typically.
