  1. I understand. I have felt the same way watching people with kitchen knives, axes, circular saws, chainsaws, car jacks, a lawn mower, even a kitchen hand mixer. Lots of stuff has risks. Knowing and caring about the risks helps you stay safe. Watching others who don't always makes me cringe. I have been on several construction sites and seen things that I just had to look away. I've also heard a lot of bad stories when it went wrong. This shouldn't stop a person from using them though. Learn the risks and think before you act.
  2. They are neat. Power Air Purifying Respirator (PAPR). 3M's Versaflo ranges $1300 - 1800. A bit hefty and pricey for me.
  3. Did your family member end up ok? I've had doctor intervention for something in my eye two different times. The first time because of no eye protection which resulted in surgical removal. The second time because my eye protection wasn't enough (darn) which luckily was able to be pulled. I sure hope it doesn't happen a third time, I'm going to be walking around in full body suit. I was told, by the first time doc, if it happens again, immediately stop what I was doing when I felt something hit my eye and go take a look in the mirror. Blinking a lot and rubbing eyes can make thin
  4. Thanks Mike. It was a bit off topic and I should have posted it to the relevant place. The angle grinder is a bit large for making burners. Though most of those same points follow through with the mini rotatories (dremel) cutting discs. I just didn't want anyone to get the sense that angle grinders were to be avoided all together. Their affordability and usefulness makes them worth having. Especially to someone just starting out. Harbor Freight's lowest end model, currently going by the name Drill Master (Black handle, 4.3amp, ) goes for $15 and can be had for $10 with a coupon.
  5. I regularly use an angle grinder with an abrasive cutoff wheel. I also use grinding wheels, flap discs, and cup brushes. If I were to start a new smithy with limited funds, it would be the first electric tool I purchased. I own several. I use them in my trade as well, so I have hours and hours of experience using them. I do not fear using them but I keep a healthy respect. Are there risks involved in using them, yes. Understanding these risks, helps with safety. It does not eliminate the risks, it makes you work differently to mitigate them. My advice if you are new to angle
  6. I need to go out and forge a foot in mouth extraction pry bar. I try hard not to talk about things I don't know. If I ever fully figure it out, there's a good chance I'll never speak again.
  7. I thought the same on the dimensions but I don't know much about ribbon burner or square wall forge flow patterns.
  8. I interpret that a little differently. Should be fine meaning the burner would run fine and the forge would heat steel. Difficult to heat evenly meaning you may have a hot spot wherever the burner is pointed because of the long/narrow dimensions. With a top center down burner, the hottest area being right in the center. If you are to be a knife smith exclusively, you might want to invest some fuss in this. I am a general smith and I prefer to have a hot spot. On the occasion that I make a knife, I just have to know the hot spot is there and work with it. With a ribbon
  9. Welcome to the club. I spend as much time tinkering with burners as I do actually using them. A lathe also makes drilling the tee concentric with the mix tube a piece of cake. If you are trying to squeak out every drop, spend most of your time on drilling that hole as close as you can get it. Having the orifice off just a little can reduce induction dramatically. The smaller the burner, the smaller the error to screw up things. Nice job on the tiny burner. I like the mini forge as well.
  10. Nice job. Looks like you are having fun over there.
  11. No problem jwmelvin. As to your expansion in round, small cones in sheet metal are not too bad to roll by hand. You can use several online calculators to get the layout of the cone. I wrote a small program which does the same but outputs a DXF file for scaled printing. I posted about it on page 48 of Burners 101. M.J.Lampert, I second what yotebuster said. The Creality machines are less expensive and can produce excellent results, however, they are very basic and require a lot of tinkering and learning in order to keep the machine printing nicely. The Prusa is more expensive but r
  12. What are you interested in now?
  13. Welcome Rusty. Good ideas. As to the ribbon burners being cast in a 3D printed mold, it has been done a little bit. I have played with it but haven't given any of it enough time to understand the particulars yet. I spent a lot of time on the head, then the nozzle, then the casting process. I plan on heading into the ribbon burner territory soon. The only other one I can remember off the top of my head is member jwmelvin printed a mold. I could not find his original post which contained the mold itself but I found his thread which shows the burner in action. I also tested some p
  14. yotebuster, the mini forge I used for the hammer is a 2 inch circle, cut down the middle and separated by 2 inches. The forge depth is 6 inches. We have made a 3 inch version (3 inch circle split by 3 inch) and a 4 inch version. We are playing with 8 to 9 inch depths for a little extra. I have not powered a forge with the 1/4" super yet. I just now got one put together so the next 2 inch forge will get one. Right now, the two inch forges are powered by detuned 3/8" burners. No wonder I have always felt so welcomed here. Birds of a feather.
  15. Thanks Mike. Part of what I like about some forums is the constant checking of information. Anyone can say anything they like, intelligent or otherwise, and then the information can be questioned by the knowledgeable. Thanks Jennifer. Solid fuel forges are hard to compete with when it comes to localization of heat. Controlled fire size, higher temperatures, and the ability to shield some of the stock from the heat. I like liquid fuel forges in their ease and cleanliness but I will probably always have a solid fuel forge as well. I do like the mini forges. The new guys tend
