Prevents joint failure in chairs, stools and log furniture.

Overview

Avoid the possibility of joint failure in your chairs, stools or log furniture with this clever expanding cutter and wedge ring system. The high-speed steel Tenon-Lok™ cutter features spring-action blades that flare out at the base, creating a dovetail-shaped round mortise. The sharpened tapered steel wedge ring then sits in the flared mortise, expanding the tenon with minimal splitting as it gets driven into place. The resulting joint will never come apart and is completely immune to weather-related expansion and contraction. Ideal for repairs or original construction, the Tenon-Lok™ system requires both a cutter and a matching wedge ring (sold here in convenient multi-packs). Every Tenon-Lok™ cutter includes a steel setter guide to create an impression on the base of the mortise for the wedge ring to rest in.

Using the 1/2" Tenon-Lok™ Dovetail Drill Bit:

1. Drill a standard 1/2" round mortise with a forstner bit or another bit of your choice.

2. Chuck the 1/2" Tenon-Lok™ cutting tool in your drill.

3. Before starting the drill, position the Tenon-Lok™ cutter all the way at the bottom of the mortise.

4. Start drilling at a low RPM and push hard enough to extend the cutter's spring-loaded dovetailing blades. Let the drill come to a complete stop before removing the cutter from the mortise.

5. On a flat surface, place the setter guide over the ring with the sharp edges up. Fit tenon into guide and tap with mallet just enough to start the ring into the end of the tenon. Now you can proceed with installing the tenon into the mortise. Either clamp the joint together or use a mallet, causing the metal ring to seat itself into the tenon, expanding it for a permanent joint.

I have used this on a set of chairs that until now have not been able to keep together for more than a month or so. So far so good. Glad I got the whole set.

I used this bit on a rocking chair. The tenon on the arm kept pulling out of the mortise. I had tried other methods of repair without success. This product works.
