I took a piece of cardboard and traced the new footprint of the larger machine. My friend let me borrow his jigsaw for some reason, so I was then able to take the original apron and trim it larger so the new machine fit. Sitting on a 3/4" piece of plywood and a 1/2" cookbook it sits flush with the table surface.
Pretty productive day for me. Made dear wife super happy to have her sewing table functional again.
