This dovetail tenon jig is designed for use with hand routers.
The tenon jig is adjustable to four different positions. You can create tenons that are 3.5″, 4.5″, 5.5″, or 6.5″ tall. If needed, shim the jig for the desired depth.
The tenons are tapered at a 10 degree angle.
The jig is fully supported when screwed into the work piece to prevent the router from tipping over.
The mortise jig creates a pocket matched exactly to the tenon created. Use the scale on the back to match to the tenon.
