I must have missed something.
You make an oil reservoir in the butt end to keep the head on tight????
So the oil migrates from the butt to the head?????
No, I drilled an oil hole in the butt to keep oil seeping into the handle.
I have seen a few old axes here with a hole and a cork in the end to hold a piece of oiled cloth which is used to wipe the blade when it has been used, I decided to put a hole in the end to keep oil seeping along the wood fibres...hence the use of cold pressed linseed without driers.
Instead of soaking the axe regularly I shall just unscrew the screw and pour some linseed inside.
What can I say, I really am lazy.
Added, and if it doesn't set the world on fire then I am okay with that as I still got to play with a new toy.
