DIY Corner Radius Templates

A set of corner radius router templates is one the most useful accessories for the router table. This 'ible presents an easy way to make your own!

Stuff you need:

• Router
• Flush Trim Router Bit
• Aluminum Angle Extrusion

To ensure perfect templates: a bearing guides the radius cut, then a jointing-action flattens the adjacent side. I drilled a hole for a view of the cutting action.

Free plans for the jig are attached!

The bearing of a flush trim router bit is removed. This will be used (temporarily) to make the templates!

Pick the radius you want, and place the bearing accordingly.

The corner of the jig should be in contact with the bearing.

The edge of the jig should be parallel to the workpiece.

Pivot the workpiece around to make the radius cut.

Cut the template at the mitre saw to any desired size.

Make a hole so you can hold onto the template while in use.

Two aluminum bits form the edges. A length of aluminum angle is cut at the mitre saw. Aluminum machines quite well with regular woodworking tools.

Create two screw holes in each aluminum piece.

Screw down the aluminum angles.

The jig can make any radius template you can imagine.
