October 13, 20196 yr I know Tim, I'm long past feeling defensive about making mistakes and deeply appreciate when someone points them. Especially when a mistake can make life so much more difficult than necessary for folks just breaking into the craft. You done good Bro. Thanks! Frosty The Lucky.

Shows you how observant I was I knew what you meant and just went with it. I guess I just listened to what you meant, not what you said - I often screw up verbally (thank god for word processors).

October 16, 20196 yr Are there updated plans for Mikey’s burners or Frosty’s T burners? I noticed this thread has gone on for three years and unclear if there is an “official” update.
October 16, 20196 yr Author There are updated versions of both kinds of burners. My changes are distributed all over this thread; sorry for the inconvenience. Frosty has just given a concise update to his burners, all in one place.
October 18, 20196 yr Mike it seems like you have reduced the number of openings in your 3/4" burner from 4 to 3, what are your thoughts on 2 openings opposite each other? Would it be an improvement or is 3 the magic number for a 3/4" burner?
October 18, 20196 yr Author I reduced the number of openings to increase swirl as the air comes into the burner, with the side benefit that the total amount of rib widths will increase for the same amount of of opening. Unfortunately, two openings will reduce swirl; not good.
October 18, 20196 yr Mike are you saying that the openings are the same width as the original plan, just with 3 instead of 4? Or does the size of the opening change too?
October 18, 20196 yr Author Three is the magic number To answer your question, Jbradshaw: Only if you want to "play it safe." I originally went for larger air openings then I needed, to play it safe. Since then, the group has discovered that more spin is better than unused extra opening space, BUT, if you under estimate how much opening is needed, you will end up needing to do some extra work to enlarge them. To get back to your question, yes, you can end up with wider rib widths--without sacrificing any of the total air opening space by reducing down from four ribs to three; a win-win situation.
October 23, 20196 yr Is there a list of build threads/instructions, either official or not that are “approved” and reflect the latest recommendations from Mikey and Frosty?
October 23, 20196 yr Author To repeat, my burner changes are scattered throughout this thread; sorry about that. But the biggest single change is mentioned right above your question. Beyond this, you would meed to look into the 3D printed burner thread, if you want to go beyond my burners... As to Frosty; he has just gone through the trouble to update his burner plans, on the thread deducted to it. just look on his thread and there it is I'm sorry, but there is no magic wand that is going to provide another book for you, and I don't think I have what it takes to write another one.

Sorry, it’s about 1000 posts over 3.5 years. I find a lot of it confusing and contradictory. There seems to be multiple build posts by others, so I thought some of them might be approved as good builds with the latest info. I’m a diy guy, but don’t need all the nuances. I’ll get back to reading the builds. Thanks
November 9, 20196 yr Author A lot of good things have been reported about ribbon burners over the last couple of years, but I would like to hear more about ribbon burners running box forges.It would seem that they would shine there.
November 9, 20196 yr Author What burner would I recommend in a box forge: Mikey or "T"? I would recommend the "T" burner over mine "any day of the week, and twice on Sunday." Why? Frost's burner has a softer flame, which will mute the tendency of box forges to have hot and cold pots. A hard flame will accentuates the tenancy for hot and cold spots. Logically, the multi-flame nozzles of ribbon burners should do even better at evenly heating a cubic internal area.
November 9, 20196 yr Author Low cost 3/4" commercial burner I get asked about decent burners at decent prices frequently, and have been intending to mention this one: link removed by request of the owner. The page has some interesting information for people who want to build, too.
November 9, 20196 yr NARB 1 and NARB 2 live in a rectangular forge and play well together. Frosty The Lucky.
November 10, 20196 yr Author 3 hours ago, Mikey98118 said: link removed by request of the owner. Ups! My bad It's the Black Beauty P75 Forge Burner, which can be Googled.
November 10, 20196 yr 20 hours ago, Mikey98118 said: I would like to hear more about ribbon burners running box forges.It would seem that they would shine there. I agree! My .125" NARB lives up top of my little round forge. I decided to reduce the interior size, so I added wool on the sides making a kind of Isosceles Trapezoid (not a box, but easy to do with IFB). Not much need for swirl like with the tube burners. The burner could be a little further up (it's about 5" high), because when I have a high billet in there, or HTing a knife perpendicular to the floor the top looks like it's in a bit more oxidizing atmosphere. Upshot is that I agree this burner works really well in a box forge.
November 10, 20196 yr Author I think you have put your finger on it. Ribbon burners don't make, or need, much swirl.
November 14, 20196 yr Apologies if I missed this info. I am particularly interested in the .025 migs being used in the 3/4”. Have there been any updates? I couldn’t find the page, but I snapped it on my phone awhile back.
November 28, 20196 yr Author First, sorry for the slow reply; I've just managed to get back on line. Here's an update on the subject .025" MIG contact tips .025" tips. are supposed to have .034" diameter orifices; some do and some are actually .023" tips (.031" orifices), that have been listed as .025" on the convenient assumption that, in wire feed welders, they are interchangeable; which is total BS, even if you were using them for welding! When re-purposed as part of a 3/4" high speed burner, the differences is infuriating. So, bottom lining, you need to look closely in the sales literature before purchase, if you want to have the optimum orifice diameter gas jet.
November 29, 20196 yr I am a fan of the 3D printer nozzles as orifices, over the mig tips. They are listed in exact size, they are brass, they are inexpensive and they have a shorter channel length which outputs a higher velocity stream per fuel pressure. I am curious what a 3/4 Mikey would do with a 0.8 to 1 mm printer nozzle.
