How to Make a Drilling Guide Block with Bushings
Host David Thiel shows how to build a jig for installing decorative dowels into box corners. Adding dowels in mitered corners adds strength and flair.
Cut the red oak into eight strips, each measuring 1 1/2" by 24", using a table saw. Guide the wood through the blade with a push stick.
Cut the 6" piece of 2" by 2" white oak into 12 small squares. The thickness of the squares is determined by the size of the carriage bolt.
Glue three small squares of white oak to one red-oak strip--one square in the middle, and one on either end. Repeat the process for three more strips of red oak and the remaining nine squares of white oak. Let the glue dry.
Glue the remaining four strips of red oak to the tops of the squares glued to the first four strips. Allow time for the glue to dry.
Use a disc sander to round off the edges of the red oak.
To use the jig, place two of the wood strips underneath the work pieces, on either side. Place the other two wood strips directly above the bottom strips, on top of the work pieces. Insert carriage bolts and wing nuts through the slots between white oak squares. The carriage bolts should be positioned at the ends of the work pieces. Tighten the nuts to hold the pieces together.
