right tool to shave drywall

Dug

If you have a jointer, just taper enough out of the piece of window trim to fit the space. Set the cut very fine, remove the guard, and begin the cut where you want to start the taper, carrying on to the end of the piece. Do this a couple of times carefully and you'll have exactly the tapered fit you want. Use a push stick, for you will need your fingers to hold the nails later.

If you need the inside edge of the casing to remain on the same plane as the rest of the trim, set your fence so that you cut a rabbet on the trim, leaving the inside edge alone.

Not been used much after house is done but still handy tool to have around. Never can have to many tools :)

1. If you can get a knife blade on the backside of the rock, then score it. Then pull it toward you and score it on the outside. It'll break off along those scores.

2. Stanley Sureform rasp does a neat job.
