Damaged filter ring

[olroy2044]

Any thoughts on repairing this? Is it even possible?

Hi You should have no trouble getting that ding out, I used to used a piece of wood with a radius on the end to match, this I mounted in the chuck of my Drill Press, another piece of wood with a radius cut out of it that I mounted in a drill press vice, held the lens with the ding in the center in this piece of wood then pressed the the other piece of wood in the chuck against it a litte at a time untill I pressed the ding out. The hardest part was trying to hold the lens in the correct postion and press down at the same time, works fine with a mild ding like this but not so good on sharper dings. I've now got a commercial lens repair vice tool, see ebay auction 280728799052 only problen with it it's 25mm one side and 49 mm the other, you have to real carefull using the 25mm side on larger filter threads like 46mm, very easy to stretch the ring out of shape the opposite direction, a range of them for each size filter thread would be ideal but there dosen't seem to be a wide range of sizes available and at about $50 a pop not that viable. the 49mm side is good up to about 55mm if one is carefull, good enough to screw filters into after getting the ding out anyhow.

I use a board with a row of different diameter semicircular holes as a rest, and a piece of wooden dowel, with a pointed end end as a chisel, to knock out dings in filter rings.

They have a tool just for that job. Look under 'lens dent repair tool' on evilbay.

That's what I've made, but out of ABS plastic. It's still soft enough to not damage the metal or the finish.

You have to be very careful as that type of metal tends to be brittle--especially after it has been bent one direction. Use a dowel made of soft wood and tap lightly.

Use a lump of blu-tak to hold the lens and absorb the bangs. It brings the dent gently out.
