JMP Fence using Rockler Fence Clamps

Hello,

Here's another cool idea that came to this April's JMP class. Neil Clemmons is the guy who thought up and engineered the original and with his permission, I made a similar one and am going to show it to you. Basically, you just drill holes along the top of the straight wooden fence and by using the clamps that are made to attach a sacrificial fence to a table saw fence, you have many options for clamp placement to hold stock or other sub fences like the wooden bias jig; it proved very handy during class and was probaby the most photographed thing in class. I started out with a 3/4" board 2 1/2" x 18" and then put a dovetail slot in it to attach to the JMP brackets.

Next steps were to find the center using the CS-2 (using a mechanical pencil in it,) mark out 45 degrees on each side and cut it out for blade clearance.

Setting up the DJ-2 to drill 11/32" (3/8" works too) holes along the top; offset the driling jig about a 1/16" to the back to allow the clamps to swing and store out of the way on the side of the fence.

Setting the depth of the holes with some tape for reference.

Drilling holes; I went 1" to each side of center and then 1 1/2" apart the rest of the way.

Here's some more on the fence. I like to use stick on sandpaper on the faces of my fences.

The reason for the offset holes; easy stowing of the clamp when not being used.

Here's a great use for this fence: holding "border" boards for doing repetitive cuts. The boards keep your stock registered and from shifting to the side as you make the cut. May also allow you to forgo clamping smaller stock which can greatly speed up your production line!

Here it is being used to hold the wooden bias jig in place.

This is a great fence to add to your collection, thanks Neil!

Thanks for writing it up.

One clarification that some may not be aware of. I originally was using locknuts to hold the clamps in registration. You can see that on the second set of pictures which came from the class. After Rutager's efforts to replicate the design, I got some thread-lock adhesive and removed the lock nuts and tightened the threaded posts down all the way with the thread-lock and it works better now than with lock nuts.

BTW, this is the fastest way I have found for cutting dovetails on the JMP. Use two captive blocks on either side of the drawer or box side and flip around. The clamps hold the pieces in tight registration.
