    Which Tool for Filter Ring Dents?

    I wanted to get something to fix these. There are pliars for this available from Micro-tools. They also have a vice like device that is much bigger and, surprisingly, less expensive. Has anybody done enough to this type of repair to make a recommendation?

    I picked up one of the vice-type tools:

    http://www.micro-tools.com/store/ite...x?ItemCode=LV1

    The first, and only, time I tried to use it, the mild steel turning rod bent all to heck without putting a dent in the dent I wanted to take out. I put it on the shelf and haven't touched it since.

    Just my $0.02.

    I have both the pliers and the spreader-vise. Iíve straightened a few lens filter ring dents, and in all cases, I achieved better results with the spreader-vise. I snug it up and tap the outside of the filter ring with a soft hammer, which seems to relax the metal slightly. Continue tightening and tapping until the ring is close to round. When I used the pliers, I always seemed to damage or mark the outside of the filter ring.

    Eric:

    Tapping may be the secret. I wouldn't trust myself to tap on the outside of the ring, though. I've had better luck cradling the lens in a hollowed out piece of hardwood, and tapping the dent outwards from the lens side with a piece of hardwood. I think Micro-Tools used to sell a hardwood cradle set.
