A router bit is round shaped, that means exact 90 degree angle cut are not possible so when joining 2 pieces perpendicularly you will have a small gap between them ( depending on the bit diameter ).
- Machine Type:
- CNC Router
- Sketchup, Laserweb4
- Machine Time:
- Bit or Laser Size:
- 1/8" - 3.175mm

Heres an image of what a bit going through a corner looks like
That corner will prevent a piece to fit into the space.
Thats where "Dog Bones" come into play.
Look at the following image
Here i have create a small relief thus eliminating the 90 degree angle.
I wanted to try this further so this project i wanted to use a Sketchup extension called " Milling tools " that creates this just by clicking the shape. You can also just draw a circle the diameter of the bit and place it in each corner.
Bellow are the images of the cut pieces and the final assembly of the bunny.
I have to admit that i made a mistake here that costed me not to achieve the intended result. I created an cut operation in the bunny head instead of a pocket for joining the body. So i had to laminate the face thus preventing me to pocket the eyes, nose and mouth .
Anyways hope you guys find it useful info and get ideas for other projects you need to do.
