I'm using the MT3 (Warco WM-18 Mill) shank...
I've had a quick look and it is all one piece... I will triple check tomorrow and strip it down completely.
So it looks like I can do a couple of things.
1. Cut the shank off and attach a new MT3 shank somehow...
2. Machine the shank down to something smaller, maybe MT2 and sleeve it back to MT3
3. Try to bend it back somehow?
Oh and any other suggestions... (other than try not to bugger it up
On the plus side, I have had a chat with the seller and he wasn't aware... He's agreed to give me some money back so I have a good boring head... and if I manage to figure out a way to sort the wobble then I'll have the deal of the century... well almost...
