Hi, I'm Dave Osborne. With over 50 years experience as a journeyman carpenter, foreman and contractor in heavy construction I enjoyed working with apprentices and sharing the tricks of the trade that others shared with me. Now I get emails from Members all over the world and we include many of my answers in our Free Monthly Newsletters. Some of my answers include drawings and instructions specific to a project, but may also answer your questions. I use correct construction terminology, so you can confidently inform your building supply dealers or contractors exactly what you need.

We have projects you can build for (and with) your kids, furniture for your wife, and sheds and gazebos. If you run into a problem or need advice your Membership includes unlimited email questions to me through our Ask Dave quick response button.
How do I cut 3 1/2" crown molding at the correct angle?
This is how to cut 3 1/2" crown molding on a compound cut-off saw.
Think of the table on your cut-off saw as the floor or the ceiling where the molding will go. Base (floor) molding is cut upright and crown (ceiling) molding is cut upside down. Crown is tricky this way, because not only is it upside down but its ends are reversed.
I usually have four sample pieces with me when I cut crown molding: one for the inside right miter, one for the inside left, one for the outside right and one for the outside left. Mark each piece, so you know which one's which. These save me cutting up expensive crown just to get my head right every time. I'm referring, of course, to a maximum of a 3 1/2" crown that will stand up vertically against the saw fence. Anything larger would have to be cut on the flat, a different procedure entirely. If your fence isn't high enough, make a 3 1/2" high fence from 1/2" plywood and screw it to your fence from the back with wood screws.
