This jig is ideal for when you'd like to cut a series of holes that are parallel to one another. The Wingnuts and slots will allow the top piece (or 'guard') to be moved back and forth with ease.

Tools & Parts
Basic Woodworking tools: Pencil, Try Square, Saw (Cross and Rip), Sandpaper, Centre punch

Step 1: The Base
Round these dimensions to the nearest whole number, and be sure to countersink the holes.
Step 2: Supporting Batons
These will be custom made to fit the drill press you currently have, lifting the jig to the appropriate height.
Step 3: Top Piece/Guard
The coach bolts have to be perfectly aligned with the slots, so when marking, use the Base for reference.
Step 4: Cut & Sand' the Side Pieces
These little blocks will stabilize the Top piece somewhat, keeping it horizontal in use.
Securing it to the 'Top piece'
Standard wood screws are all very good and well, but they can come loose over time. I'd recommend using Countersunk machine screws or any type of bolt you like; as long as it has a shank length of at least 60mm.
Step 5: Complete
A little greasin' can improve its performance, and if you want, a handle could be fitted to the Top piece too.
