Am I correct in thinking the new hammer has the same contact point as the old spade hammer, all be it a smaller contact area?
I have seen evidence of this on the underside of the roller bearing.
They are both machined above centre of the total thickness of the bar used.
May I enquire why the spade hammer is not under load all the way through the cycle and the new one is ?
About as much use at field target , as a life guard at the Olympic swimming pool.
