with everyone talking about ribbon burners it got me thinking about my new forge I have decided I need
the interior is 24 inches long 13 inches wide and 7 inches tall maybe less depending if I add a shelf
every wall allows for 3 inches of insulation including the doors
I saw on facebook a guy by the name of takach forge had simply taken a meat grinder disc and welded it to a 2 inch pipe and used it in a similar way to a ribbon burner.
things began to seem pretty simple, it seemed like all the blowtorches and various other burner I had seen in my life may have had a purpose for all those tiny holes rather than being ornamental and I figured I would experiment, I might lose some time and some scrap metal but I might learn something so it seemed worthwhile.
Besides I just relined my tiny single burner atmospheric forge I use for everything right now I need it to cure with the coating for the ceramic wool.
I used a 1 3/8 inch pipe for the burners themselves and welded the grinder plates to that they have about 1/8 th inch holes drilled in them and cost about $1.50 and are made of stainless.
takach forge used the other plate with about 1/4 inch holes on 2 inch pipe.
mine might not work its hard to tell without it being in the forge.
I wont be finishing it for awhile I dont really feel like buying the ceramic board when I wont even be around to use it, it might get damaged while I am gone.
all I have for a blower is a dayton cb004 or something like that its a 1/40th hp blower with about 112 cfm or near that I have a 2 inch gate valve for it
I am playing with this blower ever though for everyone else it didnt seem to work
I also have a zephyr s10 blower that will make 128cfm at 1.25 sp whatever that means I could probley use it to blow away hot air at the front of the forge if it wont work
anyways it is an experiment it seems to get hot its also pretty cold outside though so who knows?
at the least I have discovered a new way not to make a burner

think its running right? I was able to heat up a pipe in the open air but it took awhile

Seems to me that maybe more fuel would get you a more consistency in the burn? I dont quite follow what you mean by the pipe hot either? I mean you dont want your burner to get hot, you want it burning out in front just like it seems to be.... Anyway my feeling is any experimenting is good... you always learn something
Whatever you are, be a good one.

I built a set of burners for my latest forge and had trouble with them blowing out when up to high. I had all my pipe fittings screwed together so could change it easy. I took it apart and put in stainless pot scrubbers into the manifold where your four burners go off. I kind of pulled them apart a little bit, filled the manifold right full and started it. They burn the best I have ever done. The reason yours blows out could be the air and propane is not mixed good enough. With the pot scrubbers it mixes real good and I can turn mine up as high as I want and now I have two blowers on it, on all my other forges I always used only 1 blower. It gets so hot my refractory is burning out and I have 2800 degree refractory. What I do now is when I finish a hot job I turn it down for 15 minutes or so to cool it a bit before I shut it off so there is not so much thermal shock when I shut it off. See how that works. I can turn mine up as high as I want so far and the forge just gets hotter, no blow out or nothing, just heat.

I am going to play with it a bit and see how it works it really needs to be in the forge to tell I looked at the office size it seems like its about .040 or something close so it should be made bigger I have heard of people using 1/16 or 1/8th for a blown burner but I am not totally sure what is best
I will try 1/16 and see what happens I figure I checked my regulator its bottom end is actually 10 psi which is still too high I have a 0-15 psi regulator but I think I lost the nipple that threads into the propane tank.
if it doesnt work its not that much for a pine ridge burner or to make one

I think I drilled a 1/16 hole for the propane. With a blown forge I have never used a gauge. I just listen to it and work with how much flame is coming out and regulate the air and propane accordingly. I found the oriface size didn't matter. I regulate the propane with a valve and the air with a gate valve. Can take it from cookin to cool very easily. I have 2 small blowers on the forge and with the second one just open is about the right temperature for regular forging and if I want it hotter , just open it a bit more.

Bryce It looks like it is working pretty well just as is, don't change anything and try it in the forge as is. Then if you want you can try different things, As I see it, it running pretty good. As for orifice size, the smaller the orifice the higher the pressure need to be to get a given volume of gas, if you need more gas you can either turn up the pressure or make the orifice bigger. What ever you do test it in the forge and keep track of your changes and propane consumption, if you are running the forge for a few hours set the tank on the bathroom scale (some of them are pretty accurate) monitor the heat and fuel consumption, keep notes of your changes.
By the way and interesting burnner

well at least this thread is here to remind me of what I need to do when I get back whenever that is,
I am currently trying to contact people all over the place and see if I can connect the dots so to speak, I dont really have much money in my pocket but I am willing to do whatever it takes to make it work, its time to use my various skills to earn myself a meal and place to stay and continue on the journey.
it should be the greatest adventure of my life thus far, and that sounds as good as it gets

Pretty much tomorrow I leave but I will be sticking around ontario for abit
I am going to meet with oleg of wroughtironart.net
and John from this site.
and darryl markowitz
I know this isnt really a good time of year for work but I am going to investigate a bunch of things and I applyed for a few fab jobs in ontario and then maybe I will hang around for a while for the work to come.
I just need to figure out how to make it though the day while either not spending much money or earning just enough to exist to make it a long trip
I am trying to contact people in new york and see what I can find down there as well
I would also like to see art gallery's and samuel yellin's shop and various other things that I can come up with.
if it doesnt last for too long then I will build up some money and take another shot as soon as I can

Well good luck, It sounds like a great adventure. I wish I would have done things like that before I got strapped to a mortgage, huge shop overhead and a family....
Whatever you are, be a good one.
