The Woodpecker corner radius jig is a very nice and well done jig.In Brazil I can’t find it at stores and to order a set one is expensive.
Based at Woodpecker idea I developed myself idea and a friend of mine made it to me using acrylic sheet (1/4”).
The idea is to have a four diferent radius at the same jig.To change the radius you need only to change the fence positions.
The fence is screwed at jig using two screws per side.The fence hole is taped using 5mm screw (you can choose 3/16” screw).The jig hole is bigger than screw diameter.
Perfect,acurate and cheap.
Thanks for attention
