I've joined the club as I completed the mod today. Thanks to the earlier contributors for the information that made this possible. The smallest JIS screwdriver worked perfectly. At first glance the screwdriver looks too big, but it's a perfect fit. BTW, don't order these screwdrivers if you want to do the mod soon as they come directly from China, perhaps by pigeon. I kept the baffle and the flange together at all times and I used the Dremel technique. The grinding was taking a long time so I switched to a rat-tail metal file and it worked much faster. Since the file was pretty coarse I did the finishing with the Dremel. I probably could have taken a little more off the flange, but I didn't want to get too close to the perimeter as all of my work was hand-held. The metal was very shiny after the grinding so I used some satin paint to cover the bare edges, which I did after taking the picture below. I took a couple of test pictures with the modified lens and they looked pretty good, but I didn't compare to any older shots.

Thanks for the advice. I've ordered the recommended JIS screwdrivers.

Thanks to all who have contributed to this very helpful thread. I am contemplating this mod. One question though... regarding the three JIS screws that need to be removed, have folks had success using Phillips head screwdrivers or are JIS screwdrivers necessary? I have an assortment of small Phillips head screwdrivers but it seems that I could damage the screws if they are tight and really need JIS tools. And I assume it might be a good idea to mark the baffle before removing it so that it's clear where to cut the corners out in the baffle.
