Project - "Adding the Incra Ultra Jig to the Sommerfeld Router Table"

    I hated to cut into the beautiful oak raised panel side, but I decided that I should add a dust collector connection for the chamber under the router. When the CMT/Sommerfeld fence is in place, the dust collector attachment on that fence pulls most of the saw dust. With the Incra Jig and using straight or dovetail bits, most of the sawdust is pulled down. So I added this outlet.

    I purposely used the same connector as is used in the Sommerfeld fence so that the hose could be swapped over easily. I added a 1/4" plywood sheet to the open side to block off the vacuum there. The draw through the bit insert plate is very good. The test will be when using the jig...so that is next.

        Before I quit for the day, I had to make one quick joint to test the whole system. I have cut some 3/4" plywood scraps to make a box using a 3/8" straight bit and cutting box joints. A lot of saw dust is created in this operation. It will be a good test of the new dust collector system.

     Everything works fine. Some sawdust ends up on the table but most was sucked down through the insert plate.
   Even though this was a "test" and the box has no real purpose, I added 1/2" MDF pieces on both the front and back of the sandwich. I wanted to see how clean a box joint I could get. You can see already that there is a great deal of tearout in the MDF.

  Now I am completing the "B" cuts on the sides. Again, the MDF us badly splintered, but it is hard to see whether the plywood is cut cleanly or not.

   Well, the moment of truth. The joints assembled perfectly, and there is little tearout. I am using a piece of sandpaper to smooth away the few traces of tearout. It is a good joint, and the Incra Jig added on to the CMT/Sommerfeld Router Table works excellently.

 

   I am looking through the Incra Project Book. I think it is time for me to do another one of those great gift-type projects. Maybe Beth can look through it and make a selection. Clearly, this router table and Incra Jig combination is a great tool for the shop.
