Lens Filter Ring Vise

I recently fixed two lenses from my collection which had dented filter rings using this $36 tool from Micro-Tools.

The tool didn't come with instructions but using it is pretty straightforward. As a precaution, I covered the front element with cardboard. First, I positioned the moving jaw of the tool on the dent and aligned the threads from the jaws of the tool to mate with the threads of the filter ring. Then I gently spread out the jaws of the tool to press out the dent. I cannot over emphasize going slowly but surely!

The tool has paid for itself ;)
