Introducing the GEN II conversion kit to make your vintage Delta Unisaws J. Et-lock fence function again. 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. 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 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. 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. 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 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. 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. These fences still work as good today as the day they were introduced. No rubber bushing to harden and crack, etc. 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. Although it appears that way, it wasn’t as simple as replacing the screwdriver slotted sleeve with a knob. Our first design reused the original cast lever and provided a great improvement over the single lever clamping systems shortcomings. 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. 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. The replacement parts that you would install are shown in another of the labeled photos. 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. 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. 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. A better and more time consuming rebuild would include sandblasting and repainting of the head casting between disassembly and reassembly. Additional parts to upgrade your now fully functional fence are also available. These include a new CNC machined geared adjusting shaft, a billet knob for the adjusting shaft, a complete billet aluminum rear rail clamping block, and a new Saturn knob & stainless steel lever arm. So you know, retro-fitting a Jet-lock fence with our Gen II kit is not difficult, but one task is a bit tricky. The one and only tricky part is removing the round cams pivot shaft in the head casting. Delta press fit this shaft into a blind hole. However, our instructions and included parts will guide you through this task and all of the others. As we do more and more of these retro-fits, we are finding slight variations in about 6-8% of the castings that require that the nylon bushing on the cam be shaved a bit to center the lever and/or the nylon bushing in the lever be shaved a bit to fit up into the opening at the 5/16 diameter pin. Neither of these tasks are difficult and should be anticipated if you are installing your own Gen II kit. An added feature of our new Gen II kit is that the new billet aluminum lever arm incorporates a means to adjust the Jet-lock lever and knobs locking position, like the vintage Delta Micro-set fence had. This easy-to-make adjustment allows you to control the height of the Saturn ball and lever at the lock position. Too high a position interferes with feeding stock through the saw. Too low of a position runs the lever arm out of stroke before clamping takes place. Jet-lock fences were designed and manufactured without this capability, but we have corrected that. The kit ships in two packagesone for all of the small parts and a second for the new longer aluminum pull rod.
