Tablesaw Sled Adapted for an old 113. Saw

I was busy designing a new sled to go with my old saw. On one of the trips to the garage for measurements I saw part of a sled poking out from under the rubble (my garage is jammed with twice as many things as should fit while waiting on the new shop). I pulled it out and decided that I could adapt it and make it serviceable. One of the runners was in a great spot, the other had to be moved about 5/8".

The UHMW runners also needed to be shaved down a bit. A shoulder plane makes quick, reliable work of this.

I put double stick tape on the runner and trim it to fit.

I put dimes in the slot to raise the runner slightly. I use clamps for reference stops for placing the sled and single runner onto the saw.

The tape sticks to the sled bottom. I flip it over and add screws.

I make ZCI's in batches. Even in my current disorganized state I was able to find some blanks to replace the used ones. I also added a nicer handle. I position the handle on the rear fence so that when I grip the dummy block on the front fence with one hand and the handle with the other the sled is balanced and lifts off smoothly.

I use the 5-cut method to get to under a thou over the capacity of the sled which is about 22". That's not bragging . . . I was just plain lucky on one of the adjustments. :D

I put in the ZCI for the fence.

It's about as basic as it gets but, it's all set.

For a 36" fence I use four holes that fit the t-bolts snug; I use 1/4". These four holes in the fence are also counterbored to recess the washers and nuts.

The corresponding holes in the sled's base are slotted. These holes are also counterbored on the bottom but, shaped to follow the slot.

The BORG sells 2-packs of 'toilet bolts' that come with the washer and nut if you don't have a hoard of t-stuff hardware like I do.

The result is that the heads of the t-bolts fit flush on the bottom but have a small amount of forward and backward motion. The shaft of the t-bolts fit snuggly into the fence. I slide the fence (that's being generous as the total movement is about 1/8") to the extreme front or rear position and tighten one end. I can now use that end as the pivot point.

I use a square to get me pretty close, snug the three remaining bolts and do the 5-way cut test. I clamp a block of wood in front of the end of the fence opposite the pivot point. I loosen the three non-pivot bolt positions and can now adjust pretty delicately using paper shims between the block and the fence. Repeat 5-way cut test as required. I'm usually good for at least 3 runs, sometimes twice that many.

Similar to aligning any tool, I put myself in the state of mind that I have all the time in the world to do this. That way I don't feel pressured or stress out :). If I get a quick accomplishment of my goal I take that as a smile from the shop gods.

My newer fences have the fence set in from the base to allow me a little platform. I had planned to rig some sort of threaded-rod setup to help with aligning. I stole that idea from someone on the forum. I always seem to get the sled setup without much issue and have never followed through. If you find setup troublesome, I would bet that this can be a real help.
