A variable speed drill press and small drill bits will probably serve you better than that sewing machine. You will have to hand sew it after you drill out the holes, but it will do the job, and you will be able to use the drill press to sand and burnish the edges afterwards. You have to be gentle, but once you get the hang of drilling the holes out, it goes fast enough. I think I got my variable drill press from MicroMark, but that was like ten years ago. What I like about it is the small foot print and the variable speed, that comes in handy. I wonder if a router speed control unit would do the same thing.
