This thread will show my part in finishing the 18th c. styled axe that Jake forged last year. See original thread here:
https://www.bladeforums.com/threads/r-d-18th-c-american-axe.1657540/
I was grateful that he entrusted me to work on his axe. I shared many emails with Jake and Old Axeman to help steer my course with this. In the end the flaws in the process are mine and no fault of theirs.
The axe came to me fully forged and with much of the forge roughness removed. It looked like this.
I began by just cleaning up the perimeter and balancing the lugs.
I toyed with the idea of giving it pointed lugs but in the end rejected this idea.
Instead I elected to go with round lugs and center them on the eye. I drew lines indicating where the eye was and then shaded the area to be removed to get the shape I wanted.
I cut some of the poll and lugs off with a cutoff wheel and then finished the shaping with files.
Next I laid out the bevels. But I didn't cut them yet. In the past I've spoken about not just shaping the haft to the axe but also filing the axe to the haft. You can tweak the edge alignment a little by how you file an axe. The time to do this is when you still have metal to work with at the edge.
I began rough fitting my handle blank to the axe. This handle blank is cut from a stave of local black locust which I had air dried for 3 years. There were issues with it but more about that later. Fitting the haft revealed an issue with the axe that I hadn't noticed up until now.
The bit was twisted off line from the eye and poll a bit more than I was comfortable with.
At this point there was a lengthy email discussion with Jake, getting his advice about how I might correct this at my home forge. He recognized that even my big 145 leg vise would have difficulty resisting the torque I would have to put on this axe to straighten it.
My forge, cobbled together 9 years ago with junkyard parts. It's made from an old cast iron sink filled with clay earth and capped with refractory cement. I'm swapping out the directional tuyere I use to create a longer fire with the standard tuyere. High temperature anti-seize compound keeps the threads from locking up.
Often I use firebricks to enclose the fire and concentrate the heat.
I brought the body up to heat slowly letting the heat soak through the axe. I used that yellow pump sprayer on the left to keep the bit cool while the body came up to heat. It would be easy to burn the carbon out of the thin bit by overheating it. Once the body was up to temperature I let the bit come up, just before I performed 'the twist'.
I would need to move fast once the iron was hot. I got everything ready before I brought the axe to heat. I pre-set my vise jaws to the width where I wanted the axe to drop into. I braced off the operable jaw of the vise so it could resist the the torque I was going to put on it. I still have a little bit of movement available with it braced off. I adjusted my twisting wrenches to fit on the axe as I would need them during 'the twist'.
Then when I was all set I made...
The Twist
It came out of the twist pretty straight. But it took several more heats to clean up the wrinkles I left in it during the twist and then to straighten and slightly enlarge the eye with some makeshift drifts.
Opening the eye
Edit to add: I had dented one side of the eye while straightening the bit. To push it out I wanted my makeshift drift to move one side of the eye without moving the other side. That's why you see me cooling one side of the eye. The cool side will resist the drift.
I'm going to stop with the axe here for now and go back to that handle.
