So here's what I did if anyone is interested.
Attempt 1.
At first I put the handle end in some boiled hot water left it for a min and it slipped straight of the top part.
I first attempted to spread the split open and use a pin to put some epoxy in it, then wrapped a bit of copper wire round it and twisted it tight.... However the epoxy didn't have enough to set in the split so it didn't work.
Attempt 2.
I checked the size of the metal post with the hole of the handle and found that it was identical in size (around 6.5mm) if not a hair smaller on the handle, hence as soon as the head post was inserted into the handle the split opened wider. So I carefully drilled a 7mm hole so that the head post would slide in and out without friction. I then loosely wrapped a bit of copper wire around it in Preparation, I mixed a second batch of epoxy, spread it on the inside of the handle, (tip.... Use baby wipes to remove any excess/stray epoxy works a treat) then inserted the head post. Carefully align the head and handle, Now carefully twist the copper wire to close the split.
Lets see if it's worked in the morning.
