Hi John, I have been looking but can't find any reference to this peculiar and apparently unique mitre slot arrangement. I did however find this, a rather wonderful sounding mitre gauge from houseoftools.com pasted below. I would have to buy a better saw for a tool like this.
I'll keep looking. JessEm Mite-R-ExcelT Precision Miter Gauge Table with 4 columns and 4 rows Price SKU Quantity $244.95 CAD JTC 07100 Buy 1 $259.80 US $180.45 Euros table end Zoom Photo Tags Signs Email a Friend Description: JessEm Mite-R-ExcelT Precision Miter Gauge with Dual-Indexing. The New Mite-R-ExcelT from JessEm Tool offers an unsurpassed level of accuracy, reliability and value. Designed specifically for the serious woodworker, this fine quality precision instrument is CNC machined from heavy gauge 6061 aluminum components for rigidity and rock solid performance. The miter gauge pivots 45 degrees in both directions and features our innovative Dual-Indexing Angle Location System which utilizes a brass push-pin to index positive stops at every five degrees. A secondary range of pin locations allows for quick accurate ½ degree increments at every angle in between each 5 degrees. The gauge mechanism locks in firm with a twist of our solid aluminum handle with knurled grip and red anodized finish. The Mite-R-ExcelT fence features a heavy-gauge aluminum extrusion that's rock solid with no flex. The fence length is 27" closed and extends out to a maximum measured cut length of 36" with stop. The fence also features our unique Dual-Reference Adjustable Scale that allows accurate measurements from the blade to 24" and out to 36" when using the telescoping fence extension. The fence offers quick and easy adjustability with solid brass lock knobs and features multiple "T" tracks for attaching your own sacrificial sub-fences to the fence face for zero-clearance crosscuts.This beautifully designed and engineered tool performs as well as it looks and is sure to become your most prized table saw accessory. 12lbs.

Dale, I'll try explaining the bar, again. If the bar was square, it would be 5/8 wide by 5/16 thick. Since it isn't square, the top 1/8 of the bar narrows to 7/16. My slots are 8 and 1/8 from the insides of the slots. earlier, Dale Leavens, wrote: >OK John, > >I don't think it is really so non-standard. > >Unless I am very much mistaken you can use a standard 3/8 thick by >3/4 wide bar in that table top.
