Introduction: 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:

Step 1: How It Works

Picture of How It Works

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.

Step 2: Plans

Free plans for the jig are attached!

Step 3: Hijack a Bearing

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

Step 4: Pick Your Radius

Step 5: Set Up the Jig (1 of 2)

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

Step 6: Set Up the Jig (2 of 2)

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

Step 10: Cut Aluminum Angle

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.

Step 11: Drill the Aluminum

Really neat idea. I like the use of the tool that you are making the jigs for.

Very cool. I've had a router for a long time but not really used it in any depth--this will help get over that hurdle. Thanks for such clear instructions!

I really enjoy your instructables, than you for posting this. Hope you make more (I have subscribed to you on YouTube also).

That straight edge you used to measure 3/4" from the edge... do you happen to have a link to that? Very cool!
