Tbh I had heard similar from others regarding older lenses (even lenses 6 years old!) but was definitely worth a try.
Thank you so much I am so relieved tbh and yes will definitely post something later on

Hah !
I told you it had been put together wrong !
Or they gave up half way through the job !

Great that you've made it good again , a bit of luck's as good as anything.
Just make sure it's in there securly , use a piece if rubber to grip it .
And keep an eye on it coming loose again .
If it falls out on something hard it'll break in two .

Now you can enjoy your new lens .

Yay! Yes you were right.
Ive screwed it as far as i can and it's about 15 or more turns. I'll definitely be keeping an eye on it and if I need to twist the hood then I'll do it as if I'm tightening the lens.
Thank you and thank you for your support

And welcome to Dyxum, Stuart!

All I need to see now are some images from a near neighbour to my home town of Birmingham (well Great Barr/Walsall border actually) to make it 'complete'.

Take care and best regards, Neil.

That's a favourite. Done this myself! Typically the helicoids are multi-start so there are more wrong threads than right ones ...

Yep . Done it myself !
Put another lens back together , while being interrupted .
Rubbish picture came out if it , and it wasn't untill I picked up the lens cloth to find one element still on the bench !

There's a lot if ways to put a lens back together , but only one right way !

There's a memory for me; my father worked up until his retirement at Webley and Scott directly opposite 'The Baggies' ground and I spent many of my uni. vacations doing testing there; if you stood in the drawing office you could just about see 10% of the pitch (but not the important bits!).

Take care and best regards, Neil.
