At the risk of putting myself out of some business, here is a demo on how I make tongs,I get better with every pair too. I try and try everytime to make tongs as good as Grant made, he really set the bar high. Tongs should be light yet tough springy yet strong gripping. I make them from mild steel, I start with 1" wide by 3/8" thick by 8" long, this gives me enough for a good bolt tong with about 16" reigns, for pickup or pincer tongs I start with a 7" piece cause you don't need so much for the jaws.
Starting stock:

Here is an illustration of the shouldering I will do, I layout measurements, 1" square area for the actually part that grips the metal, then 1 1/2" for forging into the jaw neck, then another 1" square area for the rivet area then shoulder off and draw the reigns.

I dimple the steel in the locations I need, I can see this dimple while the steel is hot but it does not effect the finished forging, like a hot cut mark or a center punch mark would.

Here is my offset shoulder tool, it is made from 1" wide by 5/8" thick A36, which I water quenched no temper. In my opinion and experience this makes an excellent tool for under the powerhammer, cheap too :D. Being quenched mild steel it is tougher then regular mild steel, yet still softer then your dies therefore the tool will wear out before your dies, it's easier and quicker to forge one of these out again instead of regrinding your powerhammer dies. As long as your steel is hot the tool won't really wear either.

Now you can work two ways under the dies, a mute point if you have nice big dies like on a saymak or the bigger anyang, but my dies are 1 1/2" by 3", I am working the wrong way here for this tool the steel should be along the length of the dies and the tool perpendicular.

And this is the first heat:

you can see what the tool does here, you have to work it regular, forging the width thinner of course bulges the thickness, so I do a little bit over the tool then under the dies to squish it back, then over the tool then under the dies.

Marking the stock with the dimples in the same spots, starting with the same diameter stock, and careful forging practice should yeild very close identical parts:

Next we do it all over again for the other shoulder. Care must be taken not to take that big of a bit with the shoulder tool, or when you move down the bar it could cause a cold shut, see here I have stepped my way into the shoulder. You could also use a triangle tool to set these shoulders.

here we go:

With the same heat used to do the second shoulder, start to draw the reigns.

future Jaw area:

If you have different lengths, there is a little wiggle room in the jaw area if you have slightly different length in each jaw, just draw a touch more on the short one or upset the long one. pretty close here:

and draw the reigns:

Bust out the hot chisel and hammer, or you could use a hacksaw or you could use a bandsaw to cut a slit in the jaw area. Take care to keep it centered and go slow.

A light line at first to make sure you are on center:

then slit away

use the corner of the anvil to open up the slit

bend the jaws over in the vise, here it is halfway done. I do it so that the jaw bends back almost 90, then bend it up so the jaw is parallel with the reign but offset.

I really need to make a bending jig for this, A hossfeld type bender I think would be perfect. But not too bad:

I did not get pictures of drilling the hole (too much distortion when punching, then you have to size the hole, I just drill), but use good layout techniques and go carefully to center your hole. For these I use a 3/8" rivet, with a hole drilled in the tongs 1/32 over 3/8", again in my opinion this makes for a nice tight rivet joint that moves freely. In this size hole a 3/8" rivet actually swells in diameter into the hole as well as heading over. I am bummed I didn't get pictures of this as the way I do it doesn't require making a rivet IE heading 3/8" round then inserting then riveting. I just stick it in hot then bang away (yar;)) under the dies which heads both sides and gives me a nice head on both sides. This will be TIGHT, a hot riveted joint is steam tight it is amazing. Heat up the rivet and jaw area next to do two things, one is loosen the rivet which allows you to two fit the tongs to the stock you wish them to hold. I do this by grabbing (awkwardly) the stock I wish the tongs to hold (while the tongs are hot) then clamping this in the vice. I always use square stock as square stock fit jaws will hold round and square, whereas round fit jaws won't hold square very well.

Bada bing, wire wheel/brush them and oil em up they are ready to go:

Nice article Sam. I do something similar except I start with a longer piece of stock and lay out the tongs back to back then cut the halves apart with a hot chisel so the reins are already tapered and to proper length. Saves all that drawing out work - unless of course, you just like to use that cool power hammer...lol

Beautiful Sam!!
Looks so easy-peasey, lemon squeasy. Sorry, learned that from my son. Beautiful tongs and NO cold shuts that I can see. Looks like you have figured out how to not make the part between the jaws and the pivot too thin... That was the first mistake I made in making tongs... As well as using a center punch to mark my forging... Created cold shuts... Thanks for the tutorial!!:spin: Glad to learn from you!!

Hollis, I like this idea, but there's a few little things when I split em, one is I can adjust finely the length to get em to match real close and keep a nice fine taper to the end, I can draw them in 1 heat. I start drawing when I do the second shoulder and by the end of the next heat they are finish drawn and a dull red, then I quench em in water, adds a little extra toughness to the spring.THAT and i love using my hammer 😀
Lynn :D. Don't worry I made my fair share of jaws and pivot too thin hehe
Daryl I am glad to help! I don't know if you have a powerhammer or not, but when I was taught tongs by my teacher, he made me first do a pair all by hand, then i could use the powerhammer, gave me an appreciation and better understanding of the process.

Thanks, Sam! Cool pics and explanations.

No one really listens to anyone else, and if you try it for a while you'll see why.

Sam I do have a 25# LG, but I will have her draw out the first set by hand. We stopped in at a friends shop today and she got to try out his 200# Bradley, I have a feeling she will be soon thinking she needs one. She does need to practice moving metal and drawing out by hand. Making a set tongs has a lot of techniques that are used throughout blacksmithing, so a good teaching project.

Daryl that's awesome!
Eric, when I fit the jaws to the piece in the vice I give it a little twist and tweek to line them up.
