Lest anyone try to convince you otherwise, an anvil is any
object onto which hot iron or steel can be hammered in order to forge those
metals into different shapes. There is
no such thing as “an anvil shaped object” (ASO) as some have claimed since
anvils have no particular shape other than a flat surface. The accouterments added to anvils in the way
of bicks, hardie holes, pritchel holes etc. are additions or orifices intended
for either specialized forging processes or for accommodating tools, punches
and the like. Anvils come in all sorts
of sizes and shapes and are made of many materials. The earliest anvils were made of stone, and
around the world many smiths still ply their trade using boulders of one shape
or another as their anvil. Anvils have
been made of wrought iron, cast iron or steel or a combination. Anvils were also made using soft alloys like bronze. Therefore, any sort
of condescension regarding anvils arrives from tunneled vision and not
fact. The physics behind anvils,
however, is another matter entirely. Let
it suffice to say that the greater the mass beneath
the flat surface onto which hot steel will be placed and then pounded the
greater the opposing force that will drive back into the steel—recall Newton’s
3rd and 2nd Laws of Motion. In a properly mounted anvil the opposing
force becomes the earth itself which is a breathtaking thought to ponder. Regardless, once smelting ore was discovered
and the concept of an anvil was established humans set upon an endless quest to
advance the technology.
We have no idea how many anvils were made of nothing more
than wrought iron. Later humans learned
to manufacture steel and small steel plates were forge welded to the anvil
surface to add strength and resistance.
Rowan Taylor has an excellent video of this process on his YouTube
channel. After watching Rowan’s video I
wondered whether or not these small European anvils might’ve been part of the
original bug-out bag contents. With a
suitable small hammer a craftsman could forge arrow points in the field or
perhaps other small items as needed.
Refer to Rowan Taylor’s video on forging the hammer that compliments the
little anvil.
I’ve stated that worldwide more anvils are made from salvaged
materials than anything else. The
quintessential “anvil” that so many people equate with “an anvil” is conceptually
modern but is not the one-and-only anvil shape.
I hope you’ve concluded that you don’t need to spend five hundred or a
thousand or more dollars on an “anvil” when the local salvage yard or metal warehouse
can provide you with all you’ll ever need in the way of anvils. For years my two anvils were the underside of
a railroad track (nice and flat) and the head of an old sledgehammer. Even though I purchased a store-bought anvil a
year ago I occasionally use my sledgehammer head and upside down railroad track
rail to forge steel.
It was also about a year ago that two friends of mine decided
to upgrade their anvils to something with a bit more mass. Only one of my friends is a knifemaker; the
other is a woodworker. Both fellows are
very talented and I cherish their friendship.
Gerald makes beautiful knives and Joseph makes just about anything
related to wood you can think of. Both
of them are perfectionists. Joseph had
been using a railroad track anvil for tinkering with small bits of steel, and
Gerald was using a four-inch diameter round bar sunk into a tub of concrete.
Below are photos of the two anvils each man recently fashioned. We’re not sure what type of steel is used in
these anvils. I had mentioned to Joseph
to buy six-inch diameter 1045 about 12 inches in length. According to my calculations that chunk of
steel would weigh 96 pounds which is more than enough to accomplish what either
fellow might be looking to achieve. The
other advantage is that a round bar of that weight can be heat treated by small-shop
blade-makers and hobbyists. Anything bigger
(and heavier) becomes difficult. But
Joseph, never much concerned with the details of science or physics, remembered
my sermon about mass below the heated
steel but little else, and when he was at the metal store he said, “I’m
looking for a six-inch diameter round bar.”
“What length?”
asked one of the employees.
“I need mass,”
Joseph said.
“How about two
feet,” the employee said.
“Great! Arthur [that’s me] will be pleased.”
Is it 1045 I
wondered when he called me up and said, “I bought four-feet. Two feet for me and two-feet for Gerald.”
So Gerald
picked up his two-feet of six-inch round bar and Joseph took home his two-feet
of steel. Note that a two-foot section
of six-inch round bar weighs 192 pounds.
We’re talking some serious mass beneath the hot steel that probably
equates to something like a 500 pound store-bought anvil.
“Yeah,” you
ask. “But how are they going to heat
treat those suckers?”
To which I’ll
nod and shrug my shoulders.
Anyway, we’re
not even sure if its 1045 steel or 1018 steel.
And please don’t say things like “spark test” or something similar. Besides I wasn’t around when either fellow
created his anvil and both of them seem content now with what they’ve got. Lots of people are making anvils
using mild steel these days and no one seems all that upset. As one English fellow on YouTube says, “If
you ding your anvil then just clean it up with an angle grinder.”
Joseph's Anvil
Gerald's Anvil
So which of the two anvils do I prefer? I’m not so much a post anvil aficionado as I
am a stump anvil fan. And like I said, I
would not have gone with a 24-inch long round bar for the reasons noted above. Yes, I purchased a beautiful anvil from
Centaur Forge and I am extremely pleased with it. In fact, it’s kind of become my baby. My little shop is a lean-to bordering a barn
on one side and within a few steps of a smaller barn at one corner. But it is open on three sides so I prefer
wrapping my more expensive tools with synthetic tarps when I’m not using
them. So the Kanca is cleaned and covered after an afternoon or evening of working. Let me make it clear that if you want to buy
a modern-type anvil and you’ve got the coins to do so then by all means go for
it. Some people find old anvils and restore
them. Restoring old anvils is something
I applaud.
Okay, of the two large post anvils I think I prefer Gerald’s
design because it seems more stable. If
Joseph were to anchor his anvil to the ground I would consider it a tie. To my knowledge, Joseph’s anvil has not been
used and probably won’t ever see much use.
Gerald’s anvil, on the other hand, has seen quite a bit of use. They are presently working on a collaborative
project that will be raffled off for a charity event. I’ll post pics when the project is
finished. You will be amazed by their talents.
I had to look up "post anvil" when you mentioned it in you last post (?).
ReplyDeleteMy minor hard surface needs have been met by a piece of steel I got from dad when he passed.
It does get confusing. Lots of people do exactly as you’ve done. Just a hard chunk of steel.
DeleteI've never seen steel post anvils like those pictures. As Arty Johnson used to say on that 60's Laugh-In show: Very Interesting !
ReplyDeleteYup. And they do work.
