Introduction: Jig for Cutting Perfect Crown Molding
Cutting perfect crown molding can definitely be a little tricky, as the various angles and compound cuts can be quite confusing. I made a simple jig to make it easier and safer and in this video I'm will go over how to create your own. Also, make sure to watch the video for a better perspective on the process!
Step 1: Angles
What's really confusing about crown molding is the fact that it sits half way between the ceiling and the wall, so in order to have it line up in the corners you need to make angled cuts. When you're working with crown molding you're primarily working with inside and outside corners.
Step 2: Cutting the Angles
There are two main ways to cut the molding. You can either flip it around (so it's positioned opposite from the way it's supposed to go on the wall), thereby gaining support by finding the sweet spot and holding it at an angle when cutting. The one thing about this method, is that you have to think upside down. The other option is to hold it the way it actually will sit against the wall, however in that case it's a lot easier and safer if you have a jig.
Step 3: Making the Jig
To make the jig, first position the molding as it will go on the wall, and measure how far out and how far up it will go.
Step 4: Get Your Cutlist
These measurements will determine the interior distance of the jig which you will need the molding to be cradled within. Now you can create a cut list based on these measurements.
Step 5: Cut & Assemble
Cut your plywood to size and assemble with glue and a pin nailer.
Step 6: Use the Jig!
Now you can hold the molding within the jig when cutting the crown molding and it's nice and sturdy.
Step 7: Cutting Inside and Outside Corners
When it comes to actually cutting inside and outside corners it can be a little confusing, and it's usually helpful to do some practice cuts and models. Here's a map of what cuts you need.
