Drilling Table Pins

F

OR YEARSI USEDa doweling jig to drill holes for pins in exten-
sion tables and leaves. This approach, unfortunately, requires
dozens of separate operations, each subject to error or misalignment.
So I came up with a jig that allows me to drill all the holes on each
side of a table part in perfect alignment.
The jig is simply a wooden T-beam containing precisely spaced
bushings. My jig is 48 in. long with bushings set 9 in. apart. I use
two-part drill bushings that consist of a sleeve and a bushing insert
(available in various sizes), which threads into the sleeve. Sleeves and
bushings are available from Rockler Woodworking and Hardware
(4365 Willow Dr., Medina, MN 55340; 800-279-4441). The jig, fitted
with an adjustable stop on one end, can be centered on different-
sized tabletops.
