Forging a cut-off hardie

I forged a cut-off hardie a while back. I took some pictures along the way. I hope you enjoy.

I used an ax wedged into a stump as a cut-off for a long time, but it’s time for an upgrade.
I used an ax and sledge to cut the end off the jack hammer bit.
I forged the hardie section down some.
The jack hammer bit I forged down.
This only took a few heats.
Before I evened out the edge and sharpened it with a file.
After the file work.
After I let it normalize I heated the cut-off and then quenched it in oil.
I then immediately tempered to a golden straw.
I tempered it in the oven again, twice: once after fire tempering, and once the next day.

I’ve been working on creating some extra pages for my blog. I can’t wait to publish them.

File making

I’m very found of making things from steel and sometimes I just have to ask.. how did they do that? Our rich human history of creation is an infinite pool of knowledge to wade through for inspiration. The wealth of research available is engrossing. I’ve found myself wondering about digital copies of books. Their scans seem dusty and to smell of musk like walking through a damp, gray tomb of knowledge.. Admittedly it could be my imagination. Or more likely the lack of a good shower wafting about. =)
I digress. I’m very thankful to live in an age where knowledge is abundant.

One of mans oldest tools is the file. A cutting tool like the saw. The two are nearly as ancient as the knife and it’s cousin with a little more leverage, the ax. Rocks, gems, bones and fish spines can be used to remove material for crafting. Modern files and rasp are easily recognized as the descendant’s of these ancient tools. Metal working files were known around the world in some form of another. 14th century Europe had a change in architecture and culture lead to more ironwork being refined cold with file work becoming abundant. By the 17th century file making would have been a full-time endeavor for some. A file cutter would take a shaped piece of annealed steel ground smooth with a stone or file. He’d strap it firmly to a work block or anvil with a softer metal between the file blank and anvil. Then teeth were cut into the file by hand on both sides. As many as 60 to 80 blows per minute could be delivered by an experience cutter. The angle of the chisel was dependent on the aggressiveness of the file desired but it could be between 40-65 degrees. Next the file was carefully hardened and tempered depending on the type of steel and file.

On a personal note. The studio has been organized, an office arranged and we’ve switched Internet service providers. A faster network has finally reached our neck of the woods here Clayton, NC.
Most recently a lot of my time has been spent organizing photos and a bit of modern file work. I do most of my reading, writing and photo work on a faithful ol’ laptop running Ubuntu; occasionally I migrate toward the desktop as I familiarize myself with google sketch-up so the two are not far from one another.

So hot steel leaves wilt

It’s been darn near a hundred in the shade lately. But I’ve been trying to stay hydrated by the forge. I’ve been practicing leaves. And well I have some more stuff for the ugly side of my next installment the good, bad and the ugly. But I liked these from the other day:
