Wow! I don't know how you'd do that with the side-loading bobbin. If your cabinet could raise and lower the machine easily, you could raise it up to change the bobbin, then drop it back down to sew. You'd still need the opening in the cabinet to fit around the machine. Maybe you just need a shorter desk? Or maybe the Fashion Cabinets of America model #299 sewing table.
