I have two tanks both have problems with rusty mesh in the lids. I am aware that new lids can now be bought and have two on order however after a major panic yesterday when the lock on one of the tanks failed I was forced to see if it was possible to make the other tank habitable and I am very proud to say I have changed out the old rusty mesh and replaced it with new! Left a few holes in hands from the sharp mesh but otherwise appears to have been a great success, I was wondering if anyone else has attempted such a repair? Also now does anyone have experience of the lock failing and can that be repaired? It seems such a waste throwing a tank away just because the lock is broken!
