@7777dmith7777 Rhubarb shaped fish. Fish shaped rhubarb.

[therealciaran54]

what happens if you put your hand in?

[dogdove]

blacksmithing is gay

[barbarotico]

Hey, what happen if I put my finger in that stuff?

[pberglin]

if your finger got caught in their it might turn black and blue

[LetoZeth]

Man, that's cheating!

[deezomaxima]

It's always the old guys with the serious skill.

[harobmx17]

if it shakes the foundation with every blow i bet you would have some serious bone pain if you did that for a living

[joelito101]

That metal smith is good at this...

[9DragonMaster]

i could make so much money with one of these

[MrLeonard55]

How thick is the concrete underneath?

[capnnewb]

that is totaly cute! i think that is the big blu 100 right? i have never used on personally but i hear they are good. i am partial to the old little giants though. they are so much cheaper LOL.

[Bronzecaster67]

Hey Hector ! In what way is it intense ? I just can´t see the big deal here . Maybe i´ve seen it all before...

[Hector49er]

Soo cool! I really like metalworking. That is one intense power hammer.

[demarcohigh247]

WOW that is awsome!!

you dont get tired and you can work with larger, more heavier steel stock

[vikingo1987]

buenisimo

[brewa90]

buena maquina para forja rapida !

[ImausrI]

Stupid machine. Just use a hammer.

[TheGreatSpankini]

yes a seven hundred pound hammer

let me just pick that right up with my hands

[Conan568]

Uri Hofi, the guy using this Hammer is one of the World's best smiths.

I have an 88 lb. Striker air hammer.

It was the best shop investment I've ever made.

[ActaSanctorum]

I'd love to see more videos like this one!

[manofsteal0024]

Really its hard to make ends meet nowdays. Having a skill like this is great!

[31144]

Nice video,good to know things are still made the old fashioned manual way,lovely A+

[SanitySource]

i found this interesting, exspecially the vid info, upload more im subscribing

[a71dimer]

the big blu is an awesome hammer! and were is zeevik?

[obscenesimian]

Woops I got it wrong, I referred to the smaller Kuhn Hammer by mistake. The Hammer I meant to refer to is enourmous. probably 100 Kilos or so. It came out of a naval shipyard in the bay area. I wish I could find a picture. We used it to draw out 4" x 1.5' round stock to about 5'long after making a ball in the center with the smaller hammer. That thing was fun, but it could lift you right off the floor if you had the steel just a little off.

[carbuildergirl]

Very cool! I have only used the kind of hammer (Yoder) that is customary for cold forming steel.. So this type was really interesting to see!! and you are so right, too much hit on a hammer will demolish thin steel. :)

[Justanotherson]

wouldnt get my finger caught in that,Ouch!

Nice video of the master working

[BaliMawr]

I think that you'll get faster results if you draw down on the fullering side of the die first, and then plannish to flat on the flatter side.

[jpozadzides]

Oscar - 1/8" material is probably too thin for this machine. It delivers so much force that you have to be very delicate when cold forming. It can split steel in half if you hit it too hard.

[jpozadzides]

I'm assuming you mean it's 20 kilograms (44 lbs)? The particular hammer in the video is a 155 lb. hammer (70 kilograms).

Or did you mean something else?

[oscarajoperezoso]

I find your video so interesting, but I want to see this machine shaping a 1/8" stainless steel by cold forming, Is the machine able to do that job?, How much energy has every single blow?

[BaliMawr]

You are looking for a planishing hammer, an english wheel, or something of that sort specifically made for working sheet. (I am assuming you mean 1/8" sheet?) This type of hammer delivers a type of blow appropriate for hot forging solid stock.

[obscenesimian]

Thats not so big. European design iron In sparks NV has an air hammer with a 20 kilo head. Thats a big hammer.

[RenjiFujikawa]

maybe it doesnt spark becuase they could have used a propane furnacce wich would have lowered the amount of slag on the steel piece.

[MofoKaye]

Propane furnaces cause more surface scale than a coal fire, and a properly maintained coal fire shouldn't allow slag to touch the steel at all.

[Conan568]

Not at all.

I can control the air gas mix to make a slightly carbonizing atmosphere which produces very little scale. I do it all of the time when I forge.

It's as easy as turning the gas up or down.

[MofoKaye]

Granted, they can be regulated to produce little scale, but in my experience, and that of every blacksmith I've spoken too, propane forges still produce more surface scale than a properly utilised coke forge. I'm not slating Gas Furnaces, they're a real time and money saver.

[Conan568]

I do have a custom built forge and I have almost infinite adjustment for air and gas.

Maybe that's it.

Even a coal or coke fire has a carbonizing a neutral and an oxidizing area.

Placing steel in these areas will make a difference in scale formation.

Maybe they're just so used to a coal forge they just can't be bothered to figure gas forges out.

Square gas forges don't work as well as round ones do.

Scale happens and you do have to deal with it, it's just a matter of how much.

[MofoKaye]

Yeah, all very true. The factory made gas forges are always pretty dodgy. The scale just occurs instant you take it out the fire anyway, haha.

[Conan568]

I didn't have room to mention this before, but a cold shop makes it harder to get a neutral fire in a gas forge.

I don't normally forge much when it's cold though because I don't want to risk cracking a casting on my very expensive air hammer.

[slome815]

If it's so expensive it should be able to stand up to some cold I think. It can be cold here I have never heard of any big problems because of it.

[jeremiahsineiii]

Gotta be able to afford it, alas.
