First tension your blade. I use a 1/2"-wide blade and tension it so the indicator of the saw reads 3/4". Ensure your band saw's table is square to the blade. Raise the blade guides up as far as they will go and check the blade with a square. I put four screws on the underside of my jig so I can level it in the proper position - the bearing face needs to be dead parallel to the fence's face. Loosen the jam nuts and move the threaded part of the jig up against the work you are going to be resawing -trapping it between the jig's bearing and your band saw's fence. Note that the bearing should be positioned so it's W' to V2" in front of the teeth of the saw's blade. Set the fence parallel to the blade. The distance between the blade and the fence should be the th ickness of the veneer you want to slice. I set the fence to the right of the blade so it feels more like a table saw and clamp the outfeed end of the fence to the table. Set the ball-bearing blade guides so they are snug against the sides of the blade. Ball-bearing guides are key here. Stock or aftermarket block-style guides will either heat up the blade or wear away quickly with use. Set the thrust bearing behind the blade in its standard position - it should engage the blade only when you are cutting wood. Here, you can see how my simple little jig works. The threaded section is a common $9 hinge (called a bolt hook) for a farm gate that I modified. I sawed off a vertical pin on the end of the hinge, then I bored a hole at one end and bolted a 1 Vs"-dia. bearing to the hinge (any diameter bearing will work as long as it clears the hinge). The bolt head rests on the machine's table. The threaded section of the hinge is held in place by two jam nuts and washers. The hinge is made by National Manufacturing and is stock No. N130-583. The part No. is 293.J12J1. I bought mine at Ace Hardware. Turn on the saw and make a test cut. Push the work through firmly but don't stress the motor. If you've set your jig correctly, you'll slice off perfectly consistent pieces of veneer. After your first cut, reset the jig's bearing against your next piece of work and make your next cut. popularwoodworking.com I 67 |
