How To Repair An Anvil

If you've simply bought your outset anvil, you might exist wondering how to repair or restore it. Nearly anvils are bought used and come with cracks, dents, and chips from years of utilise.

How do you repair an anvil? The most common means to repair or restore an anvil are by either grinding downward the surface, welding any missing areas, or both. However, if you're a brand new blacksmith and so trying to repair your first anvil can often do much more harm than good.

If your anvil only has small damage, try working around it. If an anvil you're considering buying has significant harm, maybe you should only move on and discover another anvil instead.

In this article I'll explain why you might want to repair an anvil. I'll go into particular about why repairing an anvil isn't always a bully idea, too as discussing some ways to set up cracks and edges if you decide to get ahead with it. Finally, I'll share some tips to help care and maintain your anvil to keep it in practiced condition for years to come.

Why Would An Anvil Demand Repair?

In that location are many reasons why an anvil may legitimately demand repair, as well every bit reasons why people might think an anvil needs to be repaired when that isn't really the case.

Chips, cracks, grooves, pitting, and dents tin make an old anvil wait really worn and damaged. But in many cases, the harm is purely artful and won't really impact your piece of work.

The chief areas where new blacksmiths might be worried about harm on their anvil is the face (the flat peak surface where most of your blacksmithing work is done), and the horn (where most bending work is done.)

Blacksmiths might too worry virtually rust or patina on their anvils and want to remove it also.

Anvils Are Somewhat Self-Repairing If Yous Just Use Them

A lot of minor imperfections in your anvil will get naturally worked out just by using your anvil.

Abrupt edges will outset to get worn smooth. And hot steel will quickly first to remove rust from your anvil.

Sometimes the best mode to fix modest damage or imperfections in your anvil is only to start using it. The constant pounding and estrus will really start to make everything pretty flat and uniform before long.

Retrieve Carefully: Do You lot Really Demand To Repair It?

Like I said earlier, chances are that trying to fix your anvil will do more harm than practiced.

If you effort to "set up" it and screw up, it tin can be a lot harder to "united nations-set" it later on.

Most anvils still take plenty of working life left in them without whatsoever kind of repairs.

Proficient blacksmithing isn't near using tools that are in pristine condition, it'due south all about your skill every bit a blacksmith. A master blacksmith can make exercise fifty-fifty with sub-par tools.

Fifty-fifty if you lot spend the time and money to go your anvil welded upward right, yous're likely to still damage and chip information technology again as a new blacksmith while you're still learning.

Minor Restoration Work

If you just desire to clean your anvil up and make it expect a bit nicer, I'd recommend taking a wire brush to information technology and removing some of the rust from the surface. This can requite your anvil a more iron/steel colour. Although I'd notwithstanding probably leave the face of the anvil and allow hot metallic and scale to naturally remove any rust or patina through use.

To brand your cleaning job easier, you lot might want to consider giving your anvil a bath in vinegar to clean it off a bit before y'all kickoff. You lot'll need a large plastic tub with a hat, several bottles of vinegar, and likely an engine hoist or something to elevator your anvil up. Identify your anvil in the tub of vinegar, making certain it's completely covered, and allow information technology soak with the lid on for virtually 48 hours. Then it will exist much easier to clean off with a wire brush afterwards.

Don't worry most edges until you've had a significant corporeality of experience with an anvil. If you actually need precipitous edges for your piece of work, it might be easier to make a hardie tool with good edges instead. In fact, y'all don't really want sharp edges as they're more likely to scrap and tin can also cause cold shuts in your work.

Yous tin also put a calorie-free coat of oil or wax on your anvil to prevent further rusting.

DON'T take sandpaper or a grinder to your anvil if you don't know what yous're doing. If you mess up the hardened meridian of your anvil, information technology will only be good as a garden ornament! The steel face of your anvil is what provides it with decades of working life.

Don't even worry if the face up of your anvil isn't perfectly flat. Well-nigh old anvils are a bit concave (the depression is called a "swale"), and they'll work only fine. If you really need to straighten a piece of metal, a cake of woods and a mallet often does a meliorate chore anyway.

Fixing A Cracked Anvil

If you want to fix a cracked anvil, the basic steps you'll need to have are to sand information technology down, grind down the cracks a flake, and weld information technology.

Yous desire to grind all the surfaces yous're going to weld to expose practiced, make clean material. Make sure to get into any fractured chips or folds.

If the crack is 3D and goes more than 8 cm deep, your anvil is almost likely too damaged to really be repaired into a good working state again. It'due south not going to exist useful for your blacksmithing unless yous were able to completely reforge information technology.

If your anvil just has a small crack that you desire to prevent from spreading any further, that's possible too. You can drill a pigsty at each end of the scissure and that should stop it from getting any worse.

Use a skillful build-up rod for welding. Avoid hard surfacing electrodes. If y'all put multiple layers of difficult surface on your anvil, in that location's a good chance that pieces volition fly off your anvil while yous're using information technology.

If you're not sure if your anvil is steel or cast atomic number 26, y'all can use a grinder to detect out. If it gives off very few sparks it's cast fe. If there are lots of sparks, then it's steel.

Heating Your Anvil

Before you weld your anvil, you lot want to estrus information technology up to betwixt 350 and 450 degrees kickoff. You tin can utilise a Tempil Stick to verify the temperature.

Lifting a full-sized anvil can be hard, so you lot can apply a more portable tool similar a propane-fired weed burner to heat your anvil up.

Yous can also use a forest fire. But if you put your anvil direct into a fire, be sure to apply a wire brush to remove all smoke deposits and carbon before you weld it.

Be enlightened that the hardy pigsty and heel surface area of your anvil has a thinner cross-section and it will rut faster than the larger and more solid areas.

Fixing Edges

When you heat up the edge of your anvil it may reduce hardening, but that's fine.

Hardness means you're more likely to fleck your anvil during use, then it's okay if your border is a bit softer. That'southward actually probably preferred for new blacksmiths.

Fixing the edges of your anvil is pretty much the aforementioned process as filling in cracks.

Bring your anvil up to around 350 or 400 degrees.

Weld your edges using a rod specifically made for building up worn parts on heavy equipment. These kind of welds will accept really proficient bear on resistance.

Later on you're done welding, you can pein the welds. This helps relieve some of the tension as the metal cools off.

Once the metal is cool, you tin grind it flat and smooth. And finally give it a bit of a smooth.

Cooling Down Your Anvil

Quenching your anvil tin be difficult and dangerous to do. You lot'd likely need a steel pulsate or something of similar size to do information technology.

A amend option is to pack your anvil in vermiculite, which is made of crushed up mica. You tin find information technology at the majority of garden centers and nurseries. It will allow your anvil to slowly cool over about eight hours. That mode there's less take chances of stress slap-up and other issues as a result of your welding.

Getting The Right Finish

When you're starting off, use a 24-grit loving cup stone if yous need to aggressively remove a good corporeality of metal. Be sure to hold it flat. Y'all'll know information technology'southward flat if y'all've got sparks coming off both sides of the cup stone.

Subsequently an initial grind, move on to flex back metal sanding disks. You want to kickoff at about 24 dust and work your way down to 240 grit over the course of v or 6 steps.

As I mentioned earlier, sharp edges can actually exist bad on your anvil as they're prone to chipping. So I'd recommend using a 100 dust or finer sanding disk to radius the edges.

For final polishing, y'all can utilise a Scotch Brite disk. This will become your anvil and so shiny that you lot'll usually be able to see your reflection in information technology!

Potential Risks Of Repairing An Anvil

As I've said already, repairing your anvil isn't without risks. If you aren't conscientious, you could end upward doing more than damage. Such as:

• You can spend a lot of time and money and make your anvil worse off than it was originally
• Making the face more than breakable and prone to cracking in welded areas
• Heating the face up of the anvil can ruin its temper in all areas in contact with the weld bead
• Edges of your anvil won't be able to hold up to heavy utilise and will start to flake out or deform

But ultimately information technology's up to you lot to decide if it's worth it.

Maintaining And Caring For Your Old Anvil

Here are some things y'all tin can do to keep your anvil in good status for as long as possible.

• Information technology's helpful to warm your anvil upwards a bit earlier using it. Cold metal is more probable to break when hit. If you can't keep your anvil in a worm room, then warm it up by laying pieces of hot atomic number 26, a oestrus lamp, an electrical coating, or something similar on elevation to warm information technology up a bit before utilize. Information technology takes a while to warm up a cold anvil, so don't expect this to be done in just a couple of minutes. As well avoid heating your anvil above 250 degrees F, as it could ruin the hardness of your anvil'due south face.
• Employ hammers that are softer than your anvil'south face. Striking ane piece of hardened steel with another can crusade sharp pieces of metallic to fly off of either your hammer or anvil. You can do some serious impairment. Information technology's also generally a smart thought to avoid striking the face up of your anvil with a hammer directly. Especially on the tips of the horn or on its edges. Keep some hot iron between your hammer and the anvil. Hot iron alone is soft and typically doesn't harm anvils. It's merely when you striking the anvil confront with cold steel that it tin bit or break.
• Be particularly conscientious on the very tip of your anvil'due south horn. These small areas are prone to bending, breaking, or mushrooming if they're repeatedly struck with heavy hammer blows. The edges of your anvil are also particularly weak areas. All anvils will suffer some kind of edge damage over fourth dimension.
• Generally you want to use a hammer or sledge that's less than 1/l^thursday the weight of your anvil. Then if you're using a 150 lb anvil, you don't really want to use a hammer heavier than 3 lbs. Some people use a one/30 rule instead of 1/l, but for beginners who aren't confident with their swing however I'd err on the side of caution.
• You tin can utilise WD40, wax, or similar items to continue your anvil rust-free and polish. Anvils tin rust when they come into contact with water or dampness if not protected. Notwithstanding, sometimes an anvil that'due south too shiny and slick can be more than difficult to use than one with a mild rust or patina on it.
• Leaving objects on your anvil can crusade condensation during changes in temperature, peculiarly in high humidity. Don't store items on your anvil when it's not in use. It can also be a good thought to embrace your anvil with a cotton towel when non in utilise. A towel volition keep grit, dust and other stuff off your anvil that could attract moisture.
• You can take out pocket-size dents and dings in the face of your anvil by lightly hitting around them with the rounded terminate of a brawl pein hammer.

What If I Just Desire My Anvil For Ornament?

If you lot don't plan to use your anvil for actual blacksmithing and only plan to utilise it every bit a lawn ornamentation or for a tabular array, then it doesn't really matter what you do to information technology.

Feel free to grind information technology down, sand it, or whatever y'all want to do to make it more aesthetically pleasing. Information technology won't matter to you if you maintain the hardness and temper of the anvil's confront.

You can too seal it with annihilation you desire to prevent rusting and keep it looking shiny, even in outdoor weather.

The only downside is that in one case you ruin your anvil for the sake of making it into a ornamentation, it can only e'er exist a decoration. If y'all e'er desire to re-sell it in the future, it will have less value since information technology likely won't serve much purpose for actual blacksmithing at that point. To use it again, yous'd likely demand to weld a new hardened steel face onto it.
