I've had a number of old axes for some time, all are in a state of decay especially the shafts which are all loose and some even have woodworm.

I weighed the heads so I could compare them to other axes I own.

.
After normalising and hardening in oil I tempered them at 270 Celsius, once by using a heated drift and temperature indicating crayons and once in the oven at gas mark 9. You can see the crayon on the edge in one of the photos below, the crayon wax melts when it reaches its designated temp, I used 2 crayons, 1 rated at 232C and one at 260C.
HT crayons used on the edge.

.Finished axes after tempering, the long shafts are 18" long.
