Good discussion from the HAMB on the dangers of tightening the water neck on the Model A Ford without breaking it!
I have seen and broken my share of water necks in the past and had resorted to gently hand tightening the necks. i recently bought a water neck from Brattons and it came with this “trick” to avoid breaking them. i did not have any old paper matches but used a couple strips of cardboard, cut from a the backer of a note pad. the trick makes sense as it loads the out side of the ear instead of trying to snap it off. such a simple solution and it worked.
just wanted to pass it on.
