How To Create A Mitered Return On Trim Molding

When installing trim molding where it doesn’t terminate into a wall, cabinet or other structure that allows you to simply cut the end straight – a mitered return will give you a professional finished end.

Cover cutting surface gaps

These tiny pieces often fall into the open throat on the saw surface and get flung backwards through the gap in the fence. Using scrap wood to create a 0-clearance cutting area both under and behind the cut. Use double sided tape to stick the sacrificial boards to the saw’s surface and each other. You’ll eventually have quite a few cuts through your sacrificial fence and the tape will help keep it in place.

How to cut mitered returns

1. The trim sits flat on the saw surface
2. The Sawblade is set at a 45• left bevel.
3. The edge of the trim that sits against the fence will flip between top and bottom

The trickiest part is getting the tiny piece cut at just the right length. You’ll likely have to cut a few pieces before getting the length perfect – and you’ll have to cut a new piece each time because you can’t safely trim down a tiny piece of wood on a miter saw.

Outside Corners

• The mitered return is an outside corner joint.
• The bevel will always cut into the backside of the trim.
• One side of the joint will be cut with the top of trim against the fence – the other side will be cut with the bottom against the fence.

1. First, cut the small return piece.
   – The edge of the trim that sits against the fence will depend on the side of the joint you are cutting.
   – Safely holding a long section of molding against your sacrificial fence, with your saw bevel set to 45•, slowly bring the blade down to cut that tiny piece.
   – IF the piece is not the correct length, start over and cut another piece until you have the length you need.
2. Now flip the trim around so the other edge is against the fence and cut the end off – creating a mating bevel.

Install Mitered Return

When installing these tiny pieces, nails often split the wood so glue is preferable. CA glue is fantastic because it sets quickly. Wood glue works but takes longer to set up so use painters tape to hold the small piece in place while the glue sets.
