For instance, when connecting sides of a drawer directly to the drawer front, one wouldn't want to use a through dovetail joint, as the ends of the tails would show through the drawer front. In this case, the best type of dovetail joint to use is the half blind dovetail.
What is a Half Blind Dovetail?:
Creating Half Blind Dovetails:
The section of the pin board that is not to be cut (thus forming the blind portion of the joint), is called the lap. The lap on the board should never be less than 1/8" thick, yet should never exceed 1/3 of the pin board's thickness, to ensure the strength of the dovetail joint.
Cutting half blind dovetails uses the following basic steps:
Test the joint's fit and trim more off of the pins if needed.
1. Plane the ends of the two pieces of stock square.
2. Mark the length of the tails, which is the width of the pin board minus the lap. Make a shoulder line at the appropriate length around the tail board.
3. Mark the tails at the desired angle.
4. Cut the tails with a Dovetailing saw.
5. Remove the waste between the tails using a bevel-edged chisel.
6. Using the completed tails, mark the pins on the pin board, aligning the shoulder cuts with the side of the pin board opposite the lap.
7. Cut the pins and clean the waste using a chisel.
Using a Dovetailing Jig:
The procedure for cutting half blind dovetails with a dovetail jig system is pretty much the same basic procedure. Mark the depth of cut on the tail board based on the width of the pin board minus the lap. Insert the tail board into the jig and cut the tails using an appropriate dovetailing router bit. Then, following the jig's instructions, mark and cut the half blind pins in the pin board.
