Whoever made your tablesaw will have them as replacement parts.
If you make your own, there's no particular reason they need to be round. A rectangular piece of heavy sheet metal with a countersunk hole for a flat head screw would be easier to make, and work just as well.
I might take the one off the miter gauge, (since it really doesn't accomplish any thing unless the wood is clamped to it) but then I would have only one of two I need.
If you have one you aren't using please let me know.
Delta has a part number for them, but the local repair place is saying two to four weeks for delivery. The online places I found are quoting the same delivery window.
I want to finish the sled, and get back to cutting wood, so thats out.
I was hoping there might be one made by one of the accessory manufacturers, that make the guide bars. The 7/8-inch by 1/8-inch t-slot at the bottom of the miter slot is an industry standard configuration on most mid and high range table saws. The after market miter gauges I've looked at all have the washer/plate on the bottom.
I will build it with out for now, but really want the washer/plate, as it helps prevent kickback if the work peice is clamped to the sled.
