Here is my Shopsmith 10ER with a custom zero-clearance insert cut from 1/4 inch plywood. Cutting to size was straight forward, but drilling the holes for the set screws proved tricky.
I also built a jig to straddle the saw's fence that allows me to rip thin stock safely. I traced the shape of a saw handle and rounded the edges on the router table. The fit was a smidge loose so I shimmed on the inside with electrical tape. Seems good now.
