How to remove front cone?

[Neil Grant]

I've managed to remove a front cone on a non-C RB 90mm using a tightly wrapped camera strap - but this won't work on my C 90mm. What other methods could I try? What about one of those Zyliss bottle openers?

Thanks if you can help.

take the beauty ring out, use a spanner to get the cell out, then the cone comes off.

post a pic of whats giving you trouble?

Thanks, I was trying to undo the barrel - but now I've unscrewed the beauty ring instead and can remove the front group. I'm able to clean clean some of the dust out of it. Seems quite embedded so may need to use some alcohol and a lens tissue.

take the rear cell out as well n clean her with denatured alcohol. canned air burst n good as new!
