Museum of America: Blacksmith (part three)

[CTBlacksmith]

Actually when you cool metal gradually it will become softer. This is because all of the molecules are allowed to relax and align. When you quench metal at the critical temperature when it becomes non magnetic you are hardening it and trapping the carbon molecules, just like liobeking said. When you quench a piece with a high carbon content it becomes very brittle so you need to temper it by heating the metal up and drawing the correct color to the working edge then quenching it.

Thanks! Used it for teaching Blacksmithing to my homeschooled 3rd grader. He really enjoyed watching you work. He says "I enjoyed the whole thing."

[sgtkhumm]

IF you want to teach him more when he gets older you can build a forge that osts nothing, just frome adobe or mud and a couple nails to block coals from falling in the tuyere and a home hairdryer. The forge im building i a big 3x5 foot coal/coke forge made from 3/8 inch plate and the whole thing may cost me 80 $. You can also get RR rail for a decent beggining anvil and hit garage sales for hammers and such and a pair of vice grips will get you through most sized stock

[starguy9]

totally awesome and well done

[liobeking]

Sometimes things need to be hardened, it's done by cooling in water to capture the carbon in the iron molecules. I never see them reheating it (to a lower temperature for a while) so it gets less brittle. Was that done by a blacksmith or was that invented later?

[mannie1952]

Actually the more gradually the metal cools the more hardened it will become.  Quenching is something I use only to control the heat in specific areas of the metal.

either you see people who don't know what they are doing or you are missing a key factor.... when i treat my handled cutters after forging i anneal, and then heat treat and temper, however i only quench the tip on a tool like this because it is going to be struck on the back, the residual heat in the mass will allow me to draw my colors back into the tip, key temperature is non magnetic, blacksmiths did know this, but they did not know the science behind it

[TomLumpkins]

I love your video's please keep them coming..

five stars from -Tom

[Dmajorproductions]

...was that last one a kansa album cover?

[wasd0ne]

CAN U use a grill as a forge?? if u have a blowdryer to blow air to thw cole??? what kind if cole do u have to use? where can u get it? can u use grill cole?? some 1 pleasw awser me!!

[mannie1952]

I would think not, unless the grill is very thick cast-iron.

@wasd0ne Pack some sand into the bottom to insulate it well, works for me

[MADdwarfWorkshop]

Love it :)

evokes that old colonial blacksmith feel.

great video!

[fishkiller41]

Hey Manny... I don't feel "LAVA-SOAP" grungy,,,,yet.. :)

[chowpappy]

I like this guy!

[Snoman830]

i thought the ending music and smashing and sparks was awesome

[tonedizzle6289]

hey, loved your blacksmith videos, im a high school senior who's getting into forging. first, where can you find borax? second, what was the name of the song that starts at 5:10? third, did it say you were in grand rapids? i live in south bend.

[dienized]

you dont need borax or flux to weld with blacksmithing, all you need to do is get the material over 860 degrees and it will free electrons makingit possible to weld in most metals, flux just burns at high temprature

[tonedizzle6289]

awesome, thanks for the reply, i was just checkin my youtube as well. what is the name of the song at 5:10, its drivin me nuts.

[PiIsYourFfriend]

I am not into forgewelding yet, but I'm pretty sure the flux helps strengthen the weld, by grabing impurities, and pulling them out when the joining peices are forced together. If I'm wrong tell me, so I don't mess something up horribly.

[herbstjh]

borax, seashells (ground), climax welding compound, all of these work well, i prefer borax that i bake at 200 degrees for 3 hours then bottle in mason jars, (to rid the moisture) the borax turns at highter tempatures into a glass like barrier that prevents oxidation inside where your joint it, without it inclusions and cold shunts would result, resulting in a failed joint, in a proper weld no seam should be visable, your sparks flying are mostly that flux being expelled, look into abana, & local

[hayhangle]

Wal-Mart has it in the laundry section

20 Mule Team Borax. get the unscented.

[KholdAxe]

Yes, u can get borax in the laundry section.

Borax grabs the scale and forces it out of the weld in a liquid form. It is necessary for a good, strong weld.

[traceur9]

If you google blacksmithing tools or supplies, or ferrier tools or supplies, almost all of those sites offer a variety of flux.

[herbstjh]

look up abana or artists blacksmiths ass of north america, and find a local state chapter then attend workshops and you will more often then not find older smiths who will have extra anvils and tools that they will sell at a more then reasonable price once you prove you want to learn this art..

[coobicek]

it may be dying but the art lives on >: (

[AmericanFabricator]

A dying art really.

[MichiganGirl32]

This is extremely fascinating. Jane Austen mentions the 'smithy, being not too far from Mr. Darcy in Derbyshire!! Is this at Blandford now? asks Jim. Thanks for bringing the old museum back for us... The blacksmith scene in the old Great Expectations from 1947 is worth a viewing, he says.
