Mirco-adjustment Box Joint Jig

Step 8: 6. make the back adjustment piece

We are going to make the back adjustment piece next
you will need a nice piece cut at 5 3/8 x 2 "x 3/4 wide

From the top left hand side of your back adjustment piece   measue down 1 3/8 and in 1 ½”and make a mark with your pencil.  Cut out with your router from your pencil mark back to the left hand side edge.
The thickness of this slot should match the thickness of whatever bolt you are using I used 6mm bolts.

On the right hand side from the top measure down 7/8” and in 2 3/4”. again mark with your pencil and make your slot with your routerto the outer edge of your wood.
