In Stock Since ancient times, the mortise and tenon joint has been one of the most classical jointing methods in woodworking. For effificiency and accuracy, the mortise is made before tenon. Also, to avoid a loose fit, the width of kerf and tenon need to be carefully measured and marked by hand, which is complicated and errors can easily occur. Needless to say, a perfect fit is difficult to control. The TM-1 and KM-1 can avoid the above problem. There is no need to comply the making order, also the measurement of kerf, mortise and tenon is unnecessary. What you need to do is position the two sliders, and then the precisely fitted joints can be made in three steps. Three steps for tenon making The TM-1 consists with one block, two sliders and two locking knobs. Once you confirm the mortise, precise tenons can be made in three steps. Step 1 Confirm the width of kerf Confirm the width of the blade kerf by using the distance between orange slider and block. Step 2 Confirm the width of mortise Confirm the width of mortise by putting the protruding parts of the block and the dark slider into the tenon. Step 3 Cutting Cut successively by using the orange slider and the block as a flip stop against the fence to achieve the precise tenon.
