trueing the surface on a hay budden anvi


Recommended Posts

hi guys we have a 288lb hay budden in the shop that has about a .100 sway in a 3 in long area of the top surface . The anvil came from a horse and carriage building shop from the early 1900's in N.J. what are some thoughts on having it Blanchard ground to be true .We work with them and not a collector .

thanks  doug

DO NOT modify the anvil until you have used it for a year (2000 hours). A 0.100" (I am guessing that is the measure you intended) is most likely from one type project and many years of use. Read normal wear.

Blanchard grinding the face to be true will remove decades and or centuries of the useful life from the anvil. Move 3 inches away and leave this feature for your future use.

I came into blacksmithing through knifemaking and the sway in the face of one of my anvils is probably it's greatest feature. It allows me to straighten work beautifully as I can push it just a hair past  straight and let it rebound to dead straight!  I wouldn't trade it for the same anvil in unused condition!

Why not just grind a large chunk of 2" plate for a dead flat surface to work on and leave the anvil be?

Leave the sway. It Can be useful And doesnt hurt the work normally made on it. If you need a perfectly flat surfave to just correct or finish a piece on get a larger lump of steel and make a stand for it. Those can be milled or ground to what you want. Anvils have limited face plate or depth of hardness or both. So grinding them does detract from them. And a solution is easy and should be inexpensive.

Comments on the site are usually made by working blacksmiths that actually use the anvil. They have seen anvils that have lost value or is no longer useful as an anvil due to good intentions. 

As mentioned above, if you want a dead flat surface, purchase a piece of heavy plate or other material and make it dead flat. Put it on a stand and have the best of both surfaces.

A 288 lb hay budden is a wonderful anvil, and to many a dream come true. That said, it is YOUR anvil and you may do with it as YOU wish.

Welcome aboard Doug, glad to have you. If you'll put your general location in the header you might be surprised how many of the gang live within visiting distance. 

Big ditto here. Please do NOT do any grinding on that fine old lady. If you're correct it's been in use for more than a century and has 0.10" wear. Grind it flat and you'll remove more than another century's life from her.

If you work in a machine shop FLAT means surface plate, NOT a milled off anvil. You could sell that beauty to a working smith for enough to buy a surface block and some Starret instrumentation. 

However, it's your anvil.

My Trenton has some sway.  I made a flatter / set station with 2" thick block of mildish steel (has 5 inch returns on a 10 inch ball bearing drop).  It works perfectly to straighten things out and is a much bigger surface area than my anvil face.  I'm with others, don't grind the face.

As has been already mentioned, it's your anvil to do with as you choose. If you still want to flatten up the top face, you should first grind/mill the bottom face. Set the anvil upside down on the working face to make the base parallel with the top face. That way, when you flip it over to kiss the top face, you'll be removing as little material as possible from the hardened face.

If you don't do this and the top/bottom aren't parallel to start with, you might end up removing a lot more to get rid of the .100" sway.

Removing .100 off the face will remove a major portion of the hardened faceplate as they were not that thick - 3/8" or less in some cases. If it is a solid tool steel top I would be very concerned about how deep the hardness goes. .100 may end up leaving you a top that is soft all over and more prone to deformation than now.

What?  Fill in the swayed part on a perfectly hard face?  That's seems like a worse choice than the grinding flat.  :o  I'd think you'd anneal the whole face around the the area you "filled in".  I'd rather see a person sell the swayed anvil and buy another one with a flatter face than mess around with it.  Sway is not a big deal unless you have a face that looks like a horse saddle or a camel's back.

Naw,  you CAN weld hardfacing on an anvil but that tends to be for major damage, not 1/10" sway. For that little spray deposition would be preferable. Regardless you'd alter the heat treatment of the face plate and without knowing just what it is it's a gamble.

Rehardening and tempering an ANVIL is NOT a trivial project.

From personal experience wirh my anvil and a long association with others, you do not mess up the temper when using Robb's process above. Even a good hard surfacing rod done properly will not affect your anvil face temper. They both do nothing more than do an excellent 100% restore of your anvil face. As advertised. Robb's rod selections just can't be beat. There is another brand that is less expensive.

And, well, what's too much sway?  Once we figure out how many angels we can fit on the head of a pin, we can debate that.  :) ;)

As for sway being a benefit,,, hmmm, once you have worked on an anvil with a beautiful, pristine, flat face,  lol, come back and lets talk.  ;)

Just my opinion,,,

Yes, the Gunther process of restoring an anvil face is excellent, but filling in the sway section isn't really the Gunther process.  I can see doing that with sections with bad torch marks or bad chunks taken out, but with sway you have a nice hard face that you'd have to fill over top with welding rod.  With that said, it's his anvil and there are no anvil police that are going to come and arrest you for doing what you want with something you paid for.  It's your anvil.

Now here's some sway - see the anvil on the far left :D:

I think there are two different (but closely related) issues here: removing material from the anvil, and the need for a machined-flat surface. Everyone has answered the bit about removing material from the anvil well enough.

Blacksmithing isn't an endeavor that requires precision tolerances and machined surfaces within thousandths of an inch. If you're looking for that, there's a different disconnect in this whole process. You're probably looking for a different process than blacksmithing.
