Most bandsaw template guides are designed for long sweeping curves. For smaller projects with tight curves a different design is needed.
This jig mounts on the bandsaw fence and is not dependent on the blade guide design. It is easily adjustable in all three axis. Left to right is accomplished with the fence, in and out is made by sliding the jig on the fence and the guide pin is pushed up or down to match the height of the workpiece then locked in place with a small bolt.
The clamps are made from inexpensive 4” U-bolts and scrap pieces of wood. The arm is a piece of softwood 1 1/2” square. The guide pin is 1/8” diameter steel. The notch on the end of the arm allows for easier set up. The bevel under the locking bolt provides a better sight line for thicker workpieces.
To set up the jig follow these steps.
Place the jig loosely over the bandsaw fence and adjust it so the blade is at least 3/16” away from the cut out in the support arm. Secure the jig to the bandsaw fence with the clamps.
Adjust the bandsaw fence so the steel pin is centered or slightly to the right of the blade. Lock the bandsaw fence.
Loosen the locking bolt that secures the steel pin to the support arm. Lower it so the pin is just above the workpiece. Tighten the locking bolt.
Using a 3/16” blade with 10 tpi I can easily easily follow a pattern without accidentally cutting into the template. With this jig I can maintain a distance no greater than 1/8” from the template without keeping a constant eye on a cut line.
Thanks for looking.
