Thankyou Don for your generous offer, though I think we agree that Nikonians should supply the correct replacement knob. I will ask them to do that (again!).

I'm tempted to write this all down to a bit of confusion somewhere along the line.

Leif,

No probs with doing it if you have no luck with Nikonians or it all drags on a bit. I am sure if you refer them to their own instructions for the replacement knob they will send the right one.

Having had a good look at the net info on the head it certainly looks to be a pretty impressive unit.

Let us know how you get on.

Don

Leif, I've been reading your thread with interest.
Your ingenuity is inspired, my hat goes off to you.

I do hope they supply the correct replacement part this time, but I have a horrible niggly feeling they're gonna let you down. I only hope it's not me getting a negative stance.

I'm sure many of us would've gone with the option Nikonians offered and been without the unit.

I have my fingers crossed that you get an adequate result on this one Leif.
Just wanted to post my words of support.
Good luck
cheers
Joe

Thanks Joe. It seems such a waste to exchange my almost perfect unit for a new one, which is part of the reason for refusing. And anyway I find the wing nut preferable to the original knob, as it is easier on the fingers.
