How to keep filter/hood from binding on lens?

[btgc]

That is, without obvious methods like using accessories with brass threads?

I have vintage hood for Konica III, it looks like both hood and lens threads are made of iron, hood's threads are for sure. If I screw in hood securely enough, then off it comes together with front element.

I wonder what could be done - probably slightly use graphite powder on hoods threads, a bit only - as I don't want it deposit on glass. Is there common wisdom I'm missing?

Thanks in advance!

No, you're not missing anything. The obvious answer is the most reliable, but, as you say, not necessarily an option. Otherwise, a VERY soft pencil (6B if you can get one) is often the easiest way to put very small amounts of graphite on the threads.

Cheers,

Mr Hick's suggestion sounds better than the "nose grease" I always used.

Thanks Roger!
Problem with hoods is like with good shoes - once one has started to use them, it's hard to go out in slippers I just feel better with hood on lens.

You're welcome!

And I feel exactly the same way about hoods, and good boots.

Don't underestimate the power of 'nose grease!'

It's my first choice of lubricant for these sorts of things!

Nose grease is great unless you've been sweating, in which case it can have long-term corrosive effects. Not good if you leave the hood on for too long.

+1 for the pencil lead tip

Guys, are you serious about nose grease, really? Hm, I can have some finest, smoothest variety - from kid's nose! After I have started to flush my nose with salt water, I'm afraid I've put myself into dependency from outer suppliers

Zen Shooter - probably I'm wrong with use of term "vintage hood" ? I called it so because it's plastic with metal threads, I think it's old enough to be vintage but I'll stand corrected.

EDIT: after pencil/graphite cure I mounted hood and added little extra torque at the end - as usually, just to be sure it will not unscrew accidentally. While taking it off lens, front element remains in place.
Thank you!.
