Drilling angled holes is not difficult to do on a drill press. But having to tilt the table and then reset it square can be a hassle. To get around this, I built this jig. The secret to the jig is a sliding wedge between the top and base. To adjust the slope of the top, you simply slide the wedge along the jig until you reach the desired angle.
The drawing shows how it’s put together. I built the base to fit the auxiliary table I already had for my drill press. (You may need to modify the jig to fit your drill press.) Flange bolts fit into the T-track on my auxiliary table to hold the jig securely.
As you can see in this detail, the top is attached to the base with a piano hinge. The top is quite a bit narrower than the base. That allows you to adjust the sliding wedge quickly and easily. The wedge slides along two slots in the base and is held in place by carriage bolts, washers, and star knobs.
With this jig, it only takes a few minutes to set up and drill angled holes, rather than spending a lot of time resetting my drill press table every time.
