Customer reviews for Mortise and Tenon Jig

Mortise and Tenon Jig

Since 1910, General Tools has grown to become the recognized industry leader for specialty hand tools and instruments. This trailblazing tool provides a quick and easy, all-in-one solution to cut both a matching mortise and tenon with a single inexpensive jig. The Mortise and Tenon Jig is ready to use right out-of-the-box to produce 1/4 in. mortise and tenon joints for cabinets, furniture and frames. Included are the bushings for also producing 3/8 in. and 1/2 in. joints. Using a plunge router with the jig, woodworkers can cut fully aligned mortises and tenons ranging from 1/4 in. to 1/2 in. wide and from 1 in. to 3 in. long. The unit can be mounted directly on a workbench or onto a board that can be clamped in a vise or to a bench. The Mortise & Tenon Joint has been used for thousands of years, but not until now did someone figure out a way to provide a quick and easy, all-in-one solution to cut both a matching mortise and tenon with a single inexpensive jig. The unit can easily handle stock ranging from 1/2 in. to 1-1/2 in. thick and can cut multiple mortises in a single long piece.

Bought this because of all the M & T I need to do on my grandfather clock. Mounted it to my bench temporarily.
This tool is useable, however it is tough to center the work piece for either tenoning or mortising. It took several tries to learn how to get the center alignments setup. (The alignment bars on this version are made of metal not plastic.)
It works and after some trial and error, which I would do with any new tool, I'm sure I'll be happy with the purchase.
Pros: All In One, Sturdy, Strong, Good Size & Weight
Cons: Difficult to Use

The General Tool's 870 Mortise and Tenon Jig provides anyone with a plunge router an accurate way to make crisp fitting mortise cuts and tenon wood joins. The jig handles 1/4 inch to 1 1/2 inch thickness stock. This tool can create mortises from 1 inch to 3 inches wide. The jig is made of heavy duty aluminum construction with an automatic centering feature. This General product manufactures both the tenon and mortise in one tool. The jig is not available in the store but I ordered online with the help of in-store staff. Home Depot shipped the tool directly to my home.
Pros: Easy to Use, All In One, Sturdy, Accurate

No, I do not recommend this product.
Although this jig is fairly well made, it does not live up to its advertised flexibility and ease of use. Right away I learned that it was not made to accept mortise stock that was less than 2" wide, which is what I was using for a cabinet face frame. It offered two workaround suggestions: the first using a shim to make of the difference in width and then setting the bit depth that much deeper. It was very difficult to make sure the hole position was centered when it was over 3/4" below the surface of the jig. Tenons proved even more of a challenge to properly align and hold in place. The brackets that hold the boards in place are narrow and are tighened by thumbscrews that make it difficult to securely position the wood and it is awkward to find way to get a square in place to make sure the wood is perpendicular. Although it makes a nice looking rounded mortise and tenon, it is just too slow, awkward, and not precise enough for most projects.

Fair product, but could use some improvements.

This jig was easy to set up and use if you follow the directions, but it could definitely use some improvements. The plastic top guides should be metal. They are a bit sloppy and I don't see them holding up to heavy use. Also, the clamping does not square up pieces easily. Take great care making sure your stock is completely where you want it in the jig. It is very easy to be off by 1/16th of an inch from one end of the mortise or tenon and really screw up the joint. I see myself making quite a few jigs to hold wood in this jig, making sure I have a repeatable cut. Other than that, my first project I did with this jig was a pretty big success. I couldn't have done all the joints without something way more expensive than this.

Mortise depth and tenon length limited to around 1.25 inch making a through mortise on a 1.5 inch leg difficult. You must route from both sides making setup awkward. Mortise on 1.5 inch stock difficult because of limited clamping surface. (Spacers required to ensure 1.5 inch stock is within reach of the built-in clamps again limiting the reach of the router bit)
Consistent mortise and tenons on several alike pieces difficult because of the amount of interpolation required. However, consistency is attainable with practice. Pieces can be re-inserted within the fixture to correct errors after becoming more familiar with the various features.
Pros: Durable, Good Size & Weight
Cons: Limited Features

My brother and I wanted to learn how to cut mortise and tenons for a repair job on our family kitchen table. We did a lot of research to find the right tool that we could also share, but all the jigs we looked at were big and costly. We finally settled on General’s Mortise and Tenon Jig because of the price and its size. We spent some time following the manual and watching the video and eventually figured out how to do the set-up and cut the mortises and the tenons with good results. The knobbed screws, used to tighten the jig to the stock are kind of small but they held the stock steady during routing anyway. The jig came with all the stuff we needed, including a very helpful centering device for aligning the router base with the router collet. All in all, once we got the hang of it, we were able to create the needed mortises and tenons for our table repair project. General’s little jig worked great for us and we would recommend it to anyone.
