If that is the whole thing, it looks just a little bit better than useless. IMHO.

So I only toy with smithing, Small fire hooks and such so far, but what is it about the setup that is not good?

I know a ground pit works but that would get tiresome for someone over 4 feet tall pretty quick. I know it hurts my back.

I would like to get more into it as time presents itself and don't want to waste time and money on something that is just a little bit better than "Useless"

Thanks!
 
Your forge design depends, a lot, on the fuel source that you will be using. There are specific blacksmithing forums that address the issue of forge design. You could put your pit forge in an oblong bucket and set it on a table. You could use an old metal drum. Lots of designs out there - that have been used and evaluated and built for little $$$.
 
So why is the one posted above " a little better than Useless"?

It looks effective to heat metal. Maybe not long pieces like for swords and Barrels.

Just wondering. :idunno:
 
It'll heat metal, however it's not going to be efficient at it...

A good forge will evenly maintain a consistent temperature troughout operation. This is very much needed when working steel so as no cool spots are present in your material ensuring even heating. Efficiency also comes from your fuel, again that design will absolutely eat up your fuel source which will eat heat, and you guessed it... efficiency.

I have two forges, and use them frequently. A forge doesn't need to be super expensive, good planning and an understanding of how metal works is very important before jumping in. Not questioning your intelligence, but most people rush to the forge before getting into the meat and potatoes of forge work, then become frustrated.

What stock do you plan to work? Low carbon steels or high carbon steels? That design you posted would more than likely work fine with the lower carbons, but it definitely would struggle with higher tool steels... again because of efficiency.

I'd shy away from soup can forges with plaster refractory linings and what have you, as mentioned before they all are better than useless, and here is were a ground forge would be much better of a choice. If you absolutely do not plan on doing any real serious forge work, indeed they will work but will burn out very quick. If your personal goal is to better your skill and get into forging more permanently, definitely spend the time to build a quality forge that will last. You'll be very happy you did. :thumbsup:
 
The firepots on commercial solid fuel forges are sloped and not too deep. This allows stock to be placed near perpendicular to the air blast. The forge in the movie has straight sides and seems to be too deep for the width. This means that you will be placing you stock down into the heat which often results in adult sparklers as the temperature varies considerably with depth. I've read that a charcoal pot can be deeper than coke or coal but should have a side blast vs a bottom blast to keep from throwing sparks. I'm guessing that the forge in the movie will have the usable fire a little deep in the pot with coal and coke as the fuel. This means that you will be wasting heat.
 
That actually looks, functionally, very much like the general-purpose forge At the local tech college on which I learned. Differences would be in the size of the fire pot and the lack of a fume hood. I'd be curious to hear what differences the critics might be able to point out between it and the big, general purpose coal forges that were in wide use back in the late 19th century/early 20th.

These days I use a small side-blast hole-in-the-ground type with two earthen walls like a Japanese swordsmith's forge. Works ok, though it can be difficult to heat longer objects, and of course I have to work sitting down, which is a real pain. Also only works with charcoal, which is a great fuel, but perhaps not everyone's cup of tea.

edited to add: Answered before I finished asking, I see. I think that using a smaller brake drum and a bit of clay inside it to shape the slope is a potential solution, though.
 
Just my opinion, but I don't see it as large enough, or efficient enough to do very much with. There are many shown on you tube videos that would be more useful. As mentioned, a forge does not have to be expensive. I made a good one from a shallow cast iron sink, some 4" square steel tubing for an air channel, a cheap squirrel cage blower and rheostat, for air control. I bolted on a 3/16" steel plate to reinforce the bottom, also bolted on the square tubing for the air channel, drilled a bunch of holes for an elongated air delivery, so I could heat treat blades. It lasted about 10 years, maybe a few more, but the cast iron finally broke down from the uneven heating. I keep it going a couple of years longer using chimney caulking. Though it only lasted 10 or 12 years, it worked very, very good. I burned forge coal in it, and easily melted part of a steel bar, just to see if it would. Later I lucked into a vertical propane forge, made to do sword blades in. The fire chamber looked like it was a water heater tank, coated inside, and had opposing openings in order to pass a sword blade through. Great forge, but lost it in a flood. The interior coating was ruined. I meant to fix it, but never have.
DISCLAIMER.
I am not much of a smith. I used my forge for heat treating more than smithing, but it was capable to do either pretty well.
 
:hatsoff: Thank you guys!! That is what I was looking for! As usual, I have learned something today!

I apologize if I came across as anything but genuinely wanting to learn!

I know we are all busy and sometimes its easier to just say "that wont work". There are a lot of us here who like to know why it wont work so we don't blunder off wasting time and money.

I would like to make more knives and Hawks and such. I have a few books and they have forge designs but I have not progressed too far. You make a great point that its not just about heating metal!

I think its human nature to see something simple and Want to go that direction. I know that's my problem every time I do something dumb! :grin:

Again Thank you!! :v
 
I built my forge from a semi tractor rim cut down with an old manhole cover that I cut out to hold the tuyere set in with fire clay and an old hand crank Champion blower mounted with black pipe. I built it over 20 years ago and it works well with coal or hard wood charcoal (not briquets). I chose to use a hand crank blower to be more traditional and use less fuel than an electric blower.

my last forge, made of mud/clay/sand from my yard. in an old wheel barrow with home made charcoal made from hardwood shipping pallets. total cost- 3 or 4 hours of my time and a day of drying. using it with charcoal promoted rapid drying. hand cranked blower. when i moved i yanked out the tweer and tossed the forge and rusty wheel barrow. that instructible looks fine to me. this hawk and knife were forged using that forge. it gets to welding heat fast, and if you`re not careful, you'll burn your steel. i have other forges, but i`ll be building a new dirt forge in the spring. already have the wheelbarrow for it.


 
Wheelbarrow, eh? Never though of that. At some point I have to rebuild my forge and Mom and Dad have an old wheelbarrow that is trash, IIRC...
 
i use an old champion blower that leaks as much oil as i can put in in it. i should try and fix that one day. it was very portable, meaning i could move it to the driveway to forge, then after it was out, move it back in out of the weather. not that rain affected it much after the first few forging sessions. small problem i did have was the glass clinkers that formed from i`m assuming the sand. it eroded the fire pit somewhat but it lasted me two/three years. i also would find clumps of pallet nails fused/welded together from the charcoal.
 
The clinkers are the waste product and should be removed as soon as they develop so they wont interfere with the air blast or any welding. A forge left outside in the rain will corrode fast due to the acids that are created from the wet coal and ashes. The forge bottom will be eaten away.
