The Bridge City Tools TM-1 Tenonmaker is a diabolically simple tool which takes the guesswork out of sizing the tenon and results in a precise fit. It acts as a flip stop, requiring only two adjustments. One for the saw blade kerf and the other being mortice width. It works with any cutter that leaves a clean, repeatable kerf, such as saw blades or router cutters. As the readings are direct, there is no need for rules, calipers or any other measuring device, thus eliminating creeping errors.
3 simple steps to perfect tenons
1: Gauge the width of your specific blade kerf by using the distance between the orange slider and block.
2: Gauge the width of mortise by putting the protruding parts of the block and the dark slider into your tenon and lock in place.
3: Now use the orange slider and the block as a flip stop against your fence to achieve perfectly fitting, precise tenons.
This is a foolproof and accurate way to make tight fitting tenons. The TM-1 Tenonmaker works every time on tenon widths from 3-50mm.
The TM-1 Tenonmaker is 105mm x 38mm x 13mm; milled from solid aircraft grade aluminum and anodised for durability.
