Use 1 gal paint stir sticks to make a new wedge strip. You can pick them up FREE from Home Depot or lowes on your next visit. Just ask for four or five and they'll gladly hand them out. Use a razor knife to score and break or score on both sides for a complete cut through.You weren't supposed to glue that strip, just tack it on with brads. With a sharp chisel you might be able to remove the old strip; any woodworker can make new strips for you. A wider strip coated with wax can be used as a starter strip for foundationless.
This is what I've started doing, just remember the wires will be gone so be careful when you inspect, don't turn it over, just lift it up.If you glued them, just cut out the wax but leave about a 2 cell section at the top, they'll draw the rest out good as new.
