    In this demonstration, the beadLOCK Loose Tenon Joint is being used over a cope and rail profile for a glass panel cabinet door.    
    First, dry fit the parts together.
Then, draw a line across the center of the joint where tenon is desired.
    Slide and snug the guide bar left to the “A” setting, locate the beadLOCK jig on the part, and align the jig with your center line. Clamp jig in place.    
    Drill holes to the desired depth.    
    Loosen the thumbscrews and shift the guide bar right to the “B” setting. snug tightly and drill remaining holes.    
    The result is an accurate, easy-to-make mortise! Now, make another mortise in the second part.    
    Cut a corresponding length of beadLOCK tenon stock and insert into mortises. The beadLOCK joint is a strong, simple, durable joining alternative for hundreds of workworking projects.    
FAQ (Frequently Asked Questions)...
The part I would like to mortise is too wide for the beadLOCK jig to center the mortise. How can I mortise into wider parts?
If the shims provided in our kit do not offset the jig block from the plate enough for your wide part, you can simply make your own shims out of scrap wood. Use ours as a pattern. If your part is so wide that our thumbscrews will not engage into the block after you add your shims, you can make some longer thumbscrews by visiting your local hardware store. Just purchase some 1/4"-20 bolts or ready rod and a couple of wing nuts and you’ll have longer thumbscrews.

I made the joint per the instructions but the centerlines don’t line-up; what is wrong?
Always use a sharp pencil and mark the parts using a square, not free hand. Line the jig to the work piece under good light; a shadow can cause error. Make a few practice joints. You will find how your tool ‘likes’ to be aligned. Some jigs work best by just ‘showing’ the centerline; some will want to ‘cover’ or ‘split’ the line.

Why does the beadLOCK tenon stock fit too loose in the mortise?
The holes were probably bored oversize due to a dull drill bit. Always use a standard twist drill bit and keep it sharp. Run the drill a minimum speed of 1500 rpm for best results.

The beadLOCK stock fits too tight in the mortise; what is wrong?
BeadLOCK tenon stock is run .010"-.015" undersize at the factory. The fit into hardwood parts will always feel tighter than softwood; hardwood is not as forgiving. Once glue is applied, a light tapping should seat the tenon. Storing the tenon stock in an unsealed container will allow the stock to ‘take-on’ moisture and swell. Always store your tenon stock in a sealed, air-tight container. Carefully inspect the mortises. If the block was not completely shifted while drilling the ‘B’ holes, the tenon will also fit too tight.

The joint fits nice but the parts do not come together flat; why does this happen?
Most commonly, the jig is pulling away from the wood during drilling. Securely clamp the jig to the work piece. One ‘C’ clamp is not enough. Clamps with wide parallel jaws work best; a good woodworking vise also works well. In addition, make sure the vise is securely mounted to a heavy bench. If not, the vise will yield slightly during drilling without the operator knowing. An angled mortise will result. Using a sharp drill bit will reduce tool pressure and produce better results. When drilling, remember to let the drill bit do the work--don’t put extra pressure on the drill.

Can I use a drill press to make the joint?
It is possible but not necessary. A hand drill is a better alternative for mortising the end grain of long work pieces that may not fit under a drill press.

Which size tenon should I use for different thicknesses?
The 3/8" tenon is perfect for thicknesses up to 5/4". Past 5/4", we recommend using a 1/2" beadLOCK tenon.

How long should I make the tenon for my joint?
For typical joints, a 1-1/2" long tenon is adequate (3/4" into each workpiece). For higher stress joints: chairs, cabinet doors, etc.... use a 2" long tenon. For highest strength (such as mortising a 1/2" tenon into a passage door), use a 3" long tenon.

Why do the instructions say not to use a brad point drill?
Brad point drills are acceptable for drilling into side grain material. However, most mortise and tenon joints require drilling into end grain. Brad point drills do not perform well when drilling end grain. Excessive tool pressure is required which decreases both safety and accuracy.
