As seen on "The Wood-Hinge Box" this is Rob's 1/4 dowel centre drilling jig. Buy it with the dvd and save $5. No extra shipping when you buy the two together.
Jig should fit any 3/8" chuck, ready to use.
The DVD - Bench side instruction on turning bits to boxes. Rob shows you how to make the jigs to turn "would be" scraps into beautiful wood hinged boxes. Using a combination of hand and power tools Rob walks you through the building processes using precision and speed. Emphasis is placed on constructing the concealed wood hinge with options shown on completing the most difficult tasks. This is the first in a new series of project dvds.
