Last weekend I scored an Incra Original Jig off of Craigslist. I have been wanting to get into dovetail and box joinery, however had not found a deal on the necessary jigs. This purchase will allow me to get started.

The Incra is mounted on a sliding base which fastens to the table saw which one or two wooden miter bars. The miter bars have flat head screws which lock the base to the table saw table. The base has an adjustment range of about 9” which is more than enough. The sliding base has two rails of hardboard which keep it straight. Two knows lock the position.

The fence is more or less a copy of the design in the jig manual. I did add a dust collection port and some reinforcement. the T track is made by cutting a 3/4” wide groove in the fence plywood, and then gluing a 1/4” tempered hardboard piece over that. Finally a 1/4” slot is cut for the bolt. I use 1/4” carriage bolts.

Stops and the right angle support round out the build.

Looks great. I have the same jig, but haven’t used it much yet. Didn’t think of it, but I like your use of the miter slot for securing the base.
