When using my Jessops "KA Auto"(!) ext. tubes on my K7, they're not talking to one another!
I remember a post mentioning removing the paint to allow contact tube/tube.(The "first" & "last" mounts are plated metal.)
How does one remove said paint?
Tried scraping but it just makes a mess of the mounts!
Paint stripper!?

Is there a particular area that needs to make contact, or the whole thing?
Any other way round it?

Thanks,

Roger.

You should get a better finish using sandpaper. I used
3M Sandblaster 180 Fine.

Its because the mount itself is another contact.
