Parts milled from solid aircraft grade aluminum and anodized for durability. Only a few moving parts which quickly allow for simple and precise calibration to the blade and the mortise. Fool proof and accurate way to make tight fitting tenons. Works with tenons up to 2” (51mm) wide.
4-1/8” (104.2mm) x 1-1/2” (37.6mm) x ½” (12.7mm)
Can I use a Tenonmaker as a kerfmaker as well? I'd like to use one tool for both tenons and dado cuts?
No. The Tenonmaker and the kerfmaker have opposite functions.
The Tenonmaker adds one kerf width to an existing mortise or groove, as gaged by the Tenonmaker, to create a tenon that fits the exact width of the mortise or slot created by using the Tenonmaker as a flip stop.
The Kerfmaker subtracts one kerf width to create a cut that exactly matches the thickness of the stock, as gaged by the Kerfmaker, to be inserted into the dado or groove created by using the Kerfmaker as a flip stop.
How would I adapt the TM-1 to work with my existing tenoning jig? I am interested in purchasing the TM-1 to use in conjunction with my Jet Tenoning Jig (Delta style tenoning jig) I don't want to have to make a shop made tenoning jig since I have a pretty good tenoning jig already.
Because this tenon jig uses a guide bar in the miter gage slot, it is incompatible with the TM-1.
If the guide bar were removed, it would be possible (there are a couple of mitigating issues that will render this concept worthless) to use the TM-1 on the back side of the table saw fence, and the tenon jig would ride along the blade side of the table saw fence.
Mortise and tenon joints go back a long way in woodworking and are one of the strongest methods of joining two pieces of wood. A precise fit is essential to insuring a strong and durable joint and most of us have used the trial and error method often involving chisels and planes in order to achieve that fit. The TM-1 Tenonmaker is a diabolically simple tool which takes the guesswork out of sizing the tenon and results in such a precise fit that you will want to find ways to show off these joints in your finished work. The TM-1, like its cousin, the KM-1 Kerfmaker, is basically a flip stop which allows you to calibrate your sawblade and the width of the mortise so that you can quickly cut absolutely perfect tenon cheeks up to 2” wide on the first attempt. You can custom size the tightness of your tenon for a friction fit or a slip fit when you calibrate for the size of the mortise. With the TM-1 in the mortise, turn the workpiece upside down. If the TM-1 remains in place, you will produce a friction fit. Loosen the TM-1 slightly (so it would fall out when turned upside down) and you have a slip fit.
