Each kit will come with complete and easy to understand instructions to allow a normal hands-on type person to complete disassembly and reassembly of a Jet-lock fence in about an hour or two. Our retrofit kit incorporates some 16 new pieces and parts to make your Jet-lock fence work as efficiently as the early Delta Micro-set fence. The photo of the reassembled head casting clearly shows the new lever, the new spring position, and the billet finger knob attached to the new pull rod for activating the rear rail clamp.

The replacement parts that you would install are shown in another of the labeled photos. The parts that are removed and discarded from the head casting from your existing Jet-lock fence are shown in one of the labeled photos. However, our just completed Gen II design went even further, prompting us to actually design and manufacture a new CNC machined lever arm for inside the head casting, along with the required bushings, spacer, pivot shafts, spring, and a longer pull rod. Our first design reused the original cast lever and provided a great improvement over the single lever clamping systems shortcomings. Although it appears that way, it wasn’t as simple as replacing the screwdriver slotted sleeve with a knob. HERE’S THE DEAL!!!! We have, for the second time, redesigned the internal components of the later Jet-lock fence to incorporate the finger nut clamping system for the rear rail clamp. No rubber bushing to harden and crack, etc. These fences still work as good today as the day they were introduced. However, before the “better idea fence” came along, early Delta fences had a finger knob to lock the rear clamp after the ball knob and lever were depressed to square the fence to the front rail. The adjustment of the top slotted sleeve is now virtually impossible to get right, so most users now just get along with a fence that won’t clamp in the rear.
After 10, then 15, and now 50 years…… These once resilient rubber bushings are rock hard, egg-shaped, cracked… There is no more “flex” in the clamping system. The adjustment wasn’t that critical because the lever arm inside the head casting was supported on a very resilient rubber bushing and could flex as required to allow the clamping components at both ends of the fence equalize. This new fence was supposed to lock the front head casting square with the rail by pushing down on the ball knob and lever and, at the same time, lock the rear of the fence at the back rail. With this second generation of our redesigned internal components for the Jet-lock fence, your fence will lock securely to the front rail and allow for finger tightening of the rear rail clamp, the same way as was proven so reliable with the earlier Delta Micro-set fence. This sale is for one (1) complete kit to eliminate the poorly designed Delta Jet-lock single levers simultaneous clamping of the front casting and the rear rail on your vintage table saw fence.
