THROUGH DOVETAIL TROUBLESHOOTING
For joints that are too loose, move the template toward you slightly.
For joints that are too tight, move the template away from you slightly.

HALF-BLIND DOVETAILS

The half-blind dovetail is one of the most common types of joints and is the ideal choice for the drawer construction.
In typical half-blind drawer construction, the joint is not visible from the front and is invisible when the drawer is
closed.
NOTE:
For miniature half-blinds, use the 4215 accessory
kit.
Use scrap wood until you are comfortable with the
jig.
You can cut half-blind pins and tails simultaneously
on the 4200 series jigs.
Mount the correct offset guides - black for the
standard and silver for the miniature.
