    When ever possible avoid burns or being injured in the first place. If in doubt, then do not do it. If you must, or insist, on being injured, call for help (intervention), call emergency services, or call a film crew before you start. It will provide them a head start on getting to where you are, and they can bring the proper equipment for the rescue. Personal responsibility: Make a list of all the body parts you can do without, eyesight, hearing, left pinkie toe etc. It is YOUR PERSONAL RESPONSIBILITY to protect everything not on that list. There are several threads on the site discussing burns and how to both avoid them treat them. What is posted is personal opinion and is NOT medical advice. For medical advice, consult a doctor.
  2. What do you use to hot cut metal? Show me your hot cut hardies, improvised or otherwise. Whitesmith posted this one made from a piece of angle iron. It can be bolted onto the hardie post if you do not have a welder. If it gets dull or deformed just touch it with a grinder.
  3. I saw the top of the stack terminating inside the exhaust hood and the exhaust hood being a power booster to get the smoke on up and out of the building, I agree that moving the smoke just close to the exhaust hood is not a good idea. Thank you for the correction.

    Never put anything on a burn that the doctor has to scrub off when you get to the hospital.

    The site stresses safety. To the beginner that does not know what is safe and what is not safe, we must alert them to the dangers early and often. Hot, heavy, sharp, and dangerous only starts the list of cautions. That said, blacksmithing can be done relatively safely. Welcome to the site. If you have trouble finding something, just ask.
  6. If you have the forge going you MUST have a window or door open to allow as much air into the room as you are exhausting out of the room. With just the supersucker in use this is a natural draft moving the forge smoke out. If you kick on the exhaust hood, you MUST have enough air entering the room to replace the air that both the supersucker AND the exhaust hood move out of the room or the stronger of the drafts will pull any extra air needed from the weaker draft sources. For instance is you have the exhaust hood running and all the doors and windows closed the only source for exhausted air is the forge chimney and it will move air DOWN to chimney to supply air to the exhaust hood. For the top of the chimney, think of putting a 90* elbow on the very top of the chimney, and pointed to the East. Any wind blowing from N, S, and W will blow around the 90, create a partial vacuum, and draw smoke up the chimney. If the wind is coming from the east, the 90 will collect the wind and channel it down the chimney. A cut off portion at the top of the chimney will, to a certain extent, do the same thing.
  7. Why? Did the super sucker not move the smoke from the forge into the chimney and out of the work area on its own? If you put a 12 inch diameter pipe into a 3 foot by 3 foot opening you will need to close off the excess open area. Otherwise it will draw room air into the open area of the exhauster. The chimney top being open will work. If needed add a chinaman's cap, or a high volatility stack which is just a larger pipe around the chimney. Cutting the chimney at an angle as shown only works if the wind blows against the tall side of the cut, W to E in your drawing. If the wind blows E to W in your drawing, it will create a pressure that may kill the draft, or even reverse the draft of the chimney.

    jabod ?

    Invite her over and make her something nice as a gift. Plus points if she swings the hammer a couple of times while making the gift.

  11. The one thing folks overlook when shutting down a solid fuel forge is the ash tube. It contains both hot embers from the fire and insulating ash that keeps those ashes hot. The ash tube MUST be dumped at the of each forge session as part of the shut down process. Propane forges heat up the entire refractory and insulation of the forge. Turning off the gas just turns off the incoming heat, NOT the heat that is stored in the refractory or insulation. Play the what if game sometime. What if the dog knocks something over, and it falls on the forge and knocks the forge over. Or the cat wants to get warm and is drawn to the forge and it's warmth? If it is too warm and what can go wrong as the animal now rapidly departs the area? Add any vermin to the list, as well as their nest building abilities. What about wind? What about an outside weather conditions, or heavy weather, that can causes a reverse draft in a chimney. I have seen this happen in a wood stove and fortunately it only filled the house with smoke. These are only some of the things that can happen. It is also why I like solid fuel fires that when they are raked apart tend to die out. Then everything is placed into a 5 gallon bucket of water, fuel, ash, coke, clinker, and yes even the ash from the ash tube, everything under 2 inches of water, you can only then think the fire is out. Do not forget the hot iron on the work table, and the work table both of which can retain heat for a long time. At the end of a forge session is a good time to sweep up so there are no embers hiding in the dust. The dust goes into the bucket of water also, NOT into a trash can. The bucket of water can later be dumped and any fuel, coke, etc can be separated out, dried, and reused. If you want you can recycle the water to the next bucket. By the way, when was the last time you checked your fire extinguisher? Did you check the smoke detectors? Are they fully functional and ready to use?
  12. Use the anvil for a year (2000 hours) and get to know each other. You may find that you do not need to make any modifications.
  13. The hole in the ground IS a proper forge. JABOD ( or any other forge) is nothing more than a hole in the ground raised to a convenient working height. The hot chisel is a piece of metal with a flattened and sharpened end. If the mild steel deforms with use, then reshape and quench the working end the next time. A higher quality chisel can be made from coil spring or leaf spring from a vehicle. When tempered it can be used on cold steel. Practice making chisels, punches, drifts, etc is a good learning experience. You get to use something you made. Then go back to the forge and make another one with a different working end. You improve with each one you make.
  14. You cutting cold metal or hot metal? For hot metal just tilt the stock 45 degrees and use the edge of the rr track to put a crease in the stock, flip it over and crease from the other side. Bend to brake into two pieces. If cold, then put a crease or cut through the stock with an angle grinder, hack saw, chisel, then bend.
