Hope you're all staying safe and healthy. We've got some great content lined up for you and we're trying our hardest to keep you inspired and entertained. We hope it's just boredom you're fighting and not illness and suffering. We're thinking deeply about those affected by Covid19 and are grateful for all the healthcare workers around the world putting their lives on the line.
If your shop is at home or it's just you, I hope you're able to make some great things. If you're allowed to be responsibly outside, as we are fortunate to be here in Montana, I hope you enjoy some nature too. If you or loved ones are struggling with health, we have you in our thoughts.
This video began filming about two weeks ago so it's a little out of date in terms of the precautions and protocol we now have at the workshop in regards to avoiding the spread of the virus.
What do you think about a live show at some point this week or next to lighten the mood and have a blast from the past of the Barker Street Forge days?
Alec
How about an update on sword you were working on that has seemed to have disappeared.
Could you do a vid on how to cover the blanket or what to use to do it please
You should try using compressed O2 tanks.
Alec, those fittings are MegaPress fitting from Viega: to the Press Tool looks to be a Ridgid.
thats a pretty wide 90 degree angle
You need bigger air supply pipes, yours are restrictive.
This.
@@AnttiBrax Doesn't matter they have to feed into the burner, he needs pressure from a compressor.
@@AnttiBrax That.
Correct. He can put any size blower, but where the gas and air combined it looks like only 1” to 1 1/2”. If he going bigger size pipe. Now you move more gas and air.
Yes, he needs to make the air pipes larger to allow the flow. Maybe add another opening to the backside of the burner.
Consider this another vote for a larger inlet/mixing pipe. You can only cram so much air or fluid through a pipe of a certain diameter.
Awesome informational educational video experience Y'alls
You need larger pipes going into your burner. Getting rid of the 90* elbows will also help. A curved 3" exhaust pipe should be just the ticket for the blower that came with it. You may need to expand your burner box on the outside.
Either up the pipe size or increase your pressure. Heck of a forge. Personally, I'd match the pipe to the size of the output on the blower.
connect the blue blower to the big black blower. that oughta give you enough air
Wow! That sure is a giant, collosal, king sized, jumbo, huge, massive forge! (Not to be tautologically redundant of course.)
I think you need a bigger tube between the blowing Mashine and the oven. Then can more air flow
Hey Alec, just a possible thing to investigate from a fluid mechanics point of view. That bigger blower may actually be powerful enough but if the plumbing lines on the forge aren't large enough the fluid viscosity is going to cause some issues with the flow. Looks like the tube where the mixing occurs is ~1inch, maybe going up to 1-1/4 or 1.5 may help and allow you to use the same blower. Good luck with it!
Edit: Most fans also have a chart from the manufacturer that shows the CFH as a function of the back pressure - you could figure out what back pressure that system is creating and then work backwards with one of those charts.
I see a 75 part project coming to automate the door on the new forge.
You might want to try putting an oxygen line directly to the blower to increase the percentage of oxygen to it,
Even a year ago... Yes. There are wifi plumbing valves. Look at automation for pools. Hayward and Jandy make automated valves to control water flow and function... From your phone!!!
"Turn it 90° up"
- proceeds to turn pipe 180° upwards :)
All you need to do is add a supper charger, two 22" turbos, and nitrous. On second thought make it 44" turbos.
I dont think it's an issue with volume of air moreso the back pressure of the piping leading from the blower to the forge. Maybe try bigger piping as well? Worth a try and its gotta be cheaper than a new blower.
You may need to have bigger plumbing because a fan creates flow and the restriction of flow cause pressure to build up
You might need bigger holes in your ribbon burner, just a thought.
I feel like you need a bigger mixing pipe, if you aren't getting enough air then that might be the next step, bigger blower needs a bigger pipe
If i buy the devilfoge dfpprok serie. And put that powder on the wool am i fine then? Are dose bricks save? Or do the need stuff on it too? Plz leav me a answer!!! Is that powder save?
Professional problem solving
Alec Steele: "I need a hook on the wall, so I'm going to spend hours making some." Also Alec Steele: "I need to make the forge hotter.... oh look, that plastic bucket will do!" XD
Bigger blower but same size pipe restricting the airflow? Perhaps needs more pipe volume?
Alec, increase the diameter of the air/fuel feed pipe to three inches. That should solve the air flow because you're currently using the same size pipe which restricts the amount of air being moved, eh? EH!
i'm impressed he didn't blow himself up
Or both blowers?
No one is saying how he said “holy granola”
ALEC, ITS YOUR FLOWPATH BEFORE THE BURNER!!!
you are swedging it down too much before your mixture point.
I spent 9 years in the oilfield as a well tester, knowing how to deal with flow and fire were essential to my survival, it's easy enough to test up before wasting a whole bunch of money.
Use your largest diameter pipe (equal to the output of the blower) and dont swedge it down until the burner housing or at the very least, After your mixture point.
Your airflow system isnt pressurized so any restriction in that line is going to have huge impacts on your volume and flow Dynamics. Keep them to a minimum and you should be able to move enough air with what you got already.
Awesome advice!!! Thank you so much!!!
I’d like to see some softer elbows to keep the air moving instead of hitting a dead end before turning to reduce the eddies in the piping. Larger piping will help reduce this as well.
I’m curious, if the pipe is that size at the burner. Doesn’t that still have the same restriction? Or is there something about fluid mechanics that makes this work? I just want to learn the science to it.
This was exactly what I was thinking. Honestly, with your metal working skills I would try to make a custom feed line that has wide smooth curves and maintains the same cross-sectional area from the blower to the burner, maybe even opening up the back plate of the burner to make it more wedge shaped. Smooth the flow as much as possible and so you minimize restrictions and when it hits the burner you get max pressure forcing it out the holes.
@@ReinQuest in fluid flow there is drag along the inner surface of the piping. Making a tight 90° turn adds a bunch of turbulence and back preasure. Increasing the pipe diameter increases the internal volume in comparison to the increase of the internal surface area.
Alec: We need to turn this 90°
Me: Okay, okay, im following along.
Alec: Proceeds to turn it 180°
Me: I believe I have been tricked, backstabbed and quite possibly bamboozled.
Those are just the new 180° circles Alec is prototyping!
It's a metric 90°, you see.
He did turned it 90 degrees, just two times.
You definitely got bamboozled
I was like "please turn it so 'it faces the other way' and not just 90°"
"you could forge anvils in this thing." Sounds like a challenge to me.
Damascus anvil..that would be absolutely mind blowing
@@Alexshockwave84 I think he already did that one time
*eyes narrow* hmmmm
Sounds like a new Steele vs. stelte(sorry I have no memory of how to spell it)
Alec: spend thousands of dollars on equipment for any and all projects, even if you only use it once.
Also Alec: just Tuck tape together a plastic bucket.
As you say, "Its a pressure thing." Think of the partial pressures involved, and run the numbers for adiabatic combustion. Propane doesn't make any hotter of a flame, but it does have the advantage of being more dense. That means it occupies less of the inlet capacity for the same energy level.
Because of the two blowers behaving the same, my suspicion would be that you're limited by fluid drag in the inlet. You need a larger diameter inlet pipe, or to reduce drag by taking out bends, smoothing the reducing fittings (that bucket can't be very good), etc... Or by moving to a higher pressure blower. With scroll blowers, this is typically done with a multi-stage unit. You're close enough that a 2-stage is probably enough, but again you can run the stoichiometric and fluid friction calcs to be sure before you order.
as an engineer in fluiddynamics I was about to write this exact comment. So instead, I upvoted you :)
I’m no engineer but you are correct. There’s to much resistance for a volume blower. Need pressure or less turns in the pipe. May or may not be correct but I know it will help.
TrojanManSCP what about increasing the diameter of the holes in the brick?
The problem is that turns in pipe act as mixer for gas/air mixture for ribbon burner. They are needed to get even burn. Short and straight pipe is good for flow but not good for mixing gasses. Sometimes there are even built in mixers inside pipes for similar burners (some bent blades or sieves put inside pipe before burner). The easiest thing to do is use higher pressure blower system. Lower pressure blower needs wider pipes and total redesign of feed pipes and maybe even burner.
Koit Kõiveer could you use a wider pipe, with a sort of mixer internally? I’m thinking something like those shitty vortex air intake things you get in eBay to add HP to your car.

It just works!!
If it works then let it, aesthetics be damned!
His blower isnt pushing enough air, because it is only getting 110 volts. Check the voltage with a multimeter
Two things:
-Oxygen concentration doesn't actually drop with altitude. It's still 20.9%. The issue is the air is less dense. Those charts show you a relative percentage, which isn't very useful really.
-Your problem isn't the blower with the larger blower. Its the restriction at the burner. The piping is big enough and and there aren't too many bends. Youre running up against the max static head of the blower because you've got too much restriction at the burner tips or the most restrictive section of pipe. Open them up. Getting a higher static pressure blower won't help either because that will reduce your max gas flow rate due to increased back pressure. You should use the manometer to test the alterations you make to the burner tip.
This is the comment I came to find. I’m glad someone else knows that the concentration doesn’t change, just the density.
Granted it won't be as effective or efficient just upping the blower power vs actually fixing the design but he would gain from a blower with more cfm at a higher pressure. It's not like a brick wall where you just stop. Diminishing returns sure but I'd be more hesitant to mess with the piping if that's indeed how it came stock.
You can make some $ on the side with pet cremation.

Alec Steele forge now featuring Chinese food.
Now THAT might just pry a 5'er out of my no-budget wallet to his Patreon to see that video.
Increase your feed pipe diameter. Wil increase the volume you're moving at a time . And also reduce the back pressure created at the reduction point .
I agree 100%.
Yall may need to make a new ribbon burner with a larger intake port as well.
Think of air like a water bottle. If the bottle neck is bigger, more volume can come out.
I.E. a 3 liter bottle can only pour as much as a one liter bottle if the openings are the same size.
The Ribbon Burner will be the bottle neck. 1 Get a screw compressor then you can press more air. or 2 make larger pipes and get a frequency converter for the fan or 3 get a industrial burner . Im for a 8-71 blower, your now living in the usa so bigger is better.
You could also turn the blower outlet to be vertical and remove that elbow joint.
The feed pipe diameter isn't the problem, a axial fan like that doesn't produce much pressure.
He needs a fan/pump with a higher pressure rating.
Maybe Alec could use that air compressor, that would create much more pressure in the intake.

Why does he need such a big blower? didnt the one it came with work?

Way bigger blower
@@Matt-ob8gj The old blower wasn't pushing enough air, and he is thinking to get a bigger blower. However, the consensus is that the pipes are too small and the back pressure is just too much. he needs larger pipes.
more air would need a bigger pipe thats why you didnt see a difference between the big and amaller blower. Cuz the amount of air that can fit in the pipe is the same
Or a fan with a better head pressure, to force more air through the small pipes
That's true if the pressure is the same. My guess is that the dust blower has a similar pressure head as the forge one, so he either needs a blower that can operate at higher pressures or a larger diameter pipe.
If he could find a way to couple the blowers so that one runs into the other, that would also increase the pressure, but be super clunky.
@@jasons5916 Or Both
I’m currently using a “bouncy house” blower for my ribbon burner and it tosses so much air I have a motor speed controller ( essentially a rheostat) to control my flame and a ball valve diverting excess air to a air curtain in front of my forge.

Hmmm... looks like your air ducting is choking up with that bigger blower. If the bigger blower produces a similar pressure differential to the smaller one, there's only so much air you can shove through a pipe, regardless of blower size.
Now, you *could* gun for a two-stage system, i.e. one blower feeding into a second one to boost the pressure, but... it may be faster and cheaper to just redo the air pipes.
Also, why not supplement oxygen in the air in-flow, or am I missing something? Same airflow, with a hotter burn, and less noisy.
Dwayne the problem with that is if your air stops the has leaks into the room and kaboom
The Manifold the gas and blower are hooked to is to small and restricting your airflow. Moving up to a larger diameter manifold will in turn increase your heat production.
Agreed. You're fighting against static pressure here. That blower has a duct that size for a reason. Scale up the plumbing or use a blower with a higher static pressure rating.
As the pressure in the manifold goes up it pushes back against the gas. With only a couple PSI it doesn’t take much to adversely affect the mixture. So yes, a larger manifold should help ... however, at some point it will not be possible to push more air through the burner (brick with all the holes) so it may be necessary to increase the size or number of holes to get more flow.
you Could forge an anvil in that thing.... care to demonstrate? Damascus 30lb anvil? mmmmaybe? gold filigree that reads "Steele" or something?!

Alec: we need a solution for more air pressure
Will: *rolls out an air compressor"
Daniel Jungmayer pressure is the problem, and it’s pressure in the flow like that is causing reduced flow.
A compressor may have high pressure but not high enough airflow.
The issue that needs to be overcome is the flow resistance in the lines. This means a larger air feed line or to install a second burner and split the feed into two.
Cold Air intake is possibly the best solution, will add more air / oxygen for the same volume, as with blowing more air in via larger motor will still be blowing the same air oxygen ratio in, but cold air being more compressed by nature will give you higher oxygen content for the same amount of air in.
Taking above idea, an expansion tank for compressed air with a regulator will lower the temperature without needing to have any sort of refrigeration unit, could also give you a good video series making it if you can get enough volume of air through it
These are very good ideas I suggestion an S&B cool air intake system (completely sattire lol)

As a natural gas locate tech, "two whole psi" is laughably low. I don't know what the mains up there run at, but general distribution pressure here in VA is 60 psi.
This. Outside my house at the road is a 100 PSI natural gas line. There is two regulators to bring it down to normal household pressure. There is a regulator at the road to bring it down first. Then the normal regulator on the house. Alec needs to call the gas company there and ask what the PSI of the main line is and ask them about getting higher PSI gas at the shop.

Drilling the hole above your head... I felt that haha
I bet that huge blower you've got is rated for high volume at low pressure, so it can't push air through that thin tube you've got going to the forge
you've got stronger blower but still the same diameter of pipes
THIS
Probably been said but by adding a larger blower with more volume to a small pipe will only increase it's velocity not pressure. In order to obviously get more volume to the flame you will need to greatly increase the piping size which will relieve the internal pressure slowing the blower and reducing the total amount of "air" to the flame.
Avoid using as many 90 degree elbows as you can,
each one you use adds 1.5 meters of resistance that can cause lack poor gas flow.

Air, like water is a fluid, so when you have a reduction of pipe from what looks like 3" down to 1" you're losing at least 66% of your volume. And yes air is more compressible than a liquid, however it's easier of the blower if you have a pipe that is the size of your blower running into the forge.
@@fatbuttbassett4732 As messy and dangerous as that is, I'd still love to see it!
@@fatbuttbassett4732 cant compress fluid huh? Well I think about 400 billion hydraulic cylinders would disagree with you.
@@joshtheking1772 hydraulic cylinders work because you can't compress a fluid (well, not very much). If fluids compressed a significant amount, hydraulics would work like pneumatics. It's the reason why we bleed our brake lines on our car, because air compresses. Source: college fluid mechanics
@TheWarGamer11 - air is NOT a fluid, it is a gas. And thus it behaves ever so slightly differently. The reason why college level flow mechanics is a bitch. Gas flows in a way that is called a compressible flow (for a very good reason). You can't just exchange fluid for gas and use the same equations.
You also can not compress liquids - hence why hydraulics even work.
@@Dinnye01 Although liquids are the most recognised fluids, air is also a fluid and gas can be a fluid. Liquids can also be a fluid. Fluid and liquid are different things. A fluid is anything which flows. If you know about 'flow [sic] mechanics' you should know this as it is fundamental, fluid is a phase of matter not a state of matter
It just keep getting bigger!!
*my friend screaming* That's what she said!!
Could it be that there is so much pressure from the fan to the duct that it doesn't burn hotter because the air mass that goes out is smaller but moves faster? so if there would be a bigger diameter duct that air would move slowly but in greater quantity ? I am no expert but that't the principle in car exhausts that if the diameter is too small it builds pressure inside the pipe and gets "chocked"
I might be just 100% wrong
Pressure versus volume. A venturi effect in old school carburetors might be what he needs. Before it enters the final expansion area constrict the flow down slightly which will raise the pressure. It appears to have adequate volume just not enough pressure to mix the fuel.
The issue is he needs O2 specifically for combustion which literally gets thinned down at higher altitudes. So he can make the pipe bigger but then his air is not moving with the desired pressure, which means he can back draft possibly. I am no expert either, but I think he needs to either use an air compressor so he had pressurized air supply or he needs 02 tanks. It's possible it just isn't economical for his shops location.
TheCoBBus your observation is absolutely correct sir
I’m just spitballing too. I hear, “We need more oxygen.” Oxy Acetalene uses an oxygen tank yeah? Is there a safe and economical way to implement that? Seems like it’d burn through an oxygen tank very quickly, and it’s more dangerous. So, we need a Venturi effect right before ignition so as to better mix fuel at expansion and combustion. So, we need more volume, and higher pressure a la larger fan than current, as current fan was adequate at sea level. Best channel on TH-cam!

Couple of things: Depending of the humidity of the air, you may want to dry out the air before you burn it (drier air has higher oxygen %). Also from some back of the envelope calculations (I may be wrong) it seems that even if you have higher flow rates introducing the same MASS of oxygen, because you have a lower concentration of oxygen at 4000ft the larger mass flow results in about a 15% cooler flame (more mass to heat up, using a specific heat of Cp = 1.00 kJ kg-1), you may want to look at injecting a small percentage of oxygen into the intake to from your oxy-acetylene setup to bring the oxygen percentage higher, because even if you increase the impeller and pipe diameter, the increased mass introduced will cool the flame.
It could also be the pipes. I know that cars with a turbo fan larger than it needs causes a spike in internal air pressure and thus robs power. The pipes may be too small.
Isn't this all based on wrong principals? Yes the 'effective oxygen' decreases with altitude, but this is because there air density is just lower, which lowers the partial pressure of oxygen. However, the actual proportions of the constituents of air doesn't change much. So, yes you've got less oxygen to work with, but you've also got less non-combustibles to waste heat on.
Imo, if Alec's flame isn't burning rich (which it didn't look like at the end there, looked stoich), then it's borked and the only thing that could increase the temp is more gas+air or better insulation.
@@TheBanana4life oxygen is denser than nitrogen so at altitude you do actually get a lower percentage/ volume of oxygen (not just the partial pressure). The argument I am making is that with more inert gas (N2) in the mixture you are essentially 'diluting' the heat. not only that but it will be harder to get a high combustion efficiency. the issue isn't the the fuel oxygen mixture (you are right it looked close to stoich) but the fact that you have more nitrogen in the mix/ volume which dilutes the energy produced.
Actually, you are right *face palm* the mixing in the troposphere (up to 12km) is pretty much uniform. My bad, so yeah more airflow is the key!
As a doctor we routinely increase O2 concentrations by adding supplemental O2 to patients. If there was a pure O2 supplementation to your blower you could significantly increase the direct O2 delivered to the furnace. you could use the variable O2 concentration to the blower to make fine adjustments to your furnace temperatures outside of the course adjustments from a simple gas faucet. Inquiry to a medical oxygen supply company to see if a large container or concentrator might add the needed concentration of O2 to your system.
The part with the drill bits cracked me up. Every single person who has ever worked with bits/sockets knows exactly how instantly soul-crushing that feeling is.
Pancreaticdefect i once flipped over a case full of bits,screws and rivets thinking it was closed... the next half hour was EXTREMELY enjoyable,me swearing while trying to pick up every tiny little screw and my colleagues laughing their asses off
“UnI-brow” 😂😂😂Stop it man! My back hurts and you’re making me laugh which is killing me!!!!
10:53 i guess you could say that you're having an extentional crisis.
Raid: Shadow Legends is really paying well for you to make all these investments. :p
this channel is just advertisement. dude's actually making things for profit regularly.
Interestingly, air contains 20.9% oxygen at all altitudes
The pressure makes a difference on how much gets into your blood.
Ahem ahem, Why does one need oxygen for flying high altitude then????
@@trentgay3437 It's a pulmonary volume vs pressure problem, the gaz composition has nothing to do with this.
@@lolaa2200 oh so there's not enough oxygen in the air in the volume of your lungs unlike at lower elevations? Kinda the point I was making
The air *is* 20.9% oxygen at all altitudes, but there is less air per unit of volume. You’re correct that you need supplemental oxygen at altitude, but the OP is also correct that the proportion of O2 in the air doesn’t change at altitude.
genuinely laughed out loud when you spilled your bits. Because it was funny, and because I've done it myself, many many many times.
we should make a club and never talk about it

You might be surprised what you can find out there using an arduino and a solenoid.
He meant a wireless transfer of the gas itself.
These kinds of blowers are built to suck high volume of air with low pressure at low air-speed. If you connect a much smaller pipe to the outlet you get limited volume and pressure. What you need is a blower which is built to produce high volume and high pressure. Maybe a leaf-blower could solve this problem. Doesn't cost much and produces a high volume of air with high speed. (Sorry for my english...)
The genie lift seems like a perfect new perch for will, I think y’all should keep it..

Alec: Use SAtanite
Me a good christian boy: ...
Yall's videos are an inspiration!
I have the solution to your problem but cannot find a way to contact you : anyway you want to gradually reduce the pipe size coming from your blower. I go from a 4 inch blower output to a 1 inch at the burner flare over the course of about 5 ft of heater hoses gradually necking til it meets at a 2 in to 1 in black iron reducer then has about 3 ft of 1in black pipe elbowing about til it goes to flare inside forge. The gradual reduction in size simply increases the pressure at which air is supplied and yes it does strain the bouncy house blower.... But that is what they were designed for. And infact one runs smoother with that bit of backpressure
Maybe worth looking at increasing the diameter of pipe between blower and forge inlet ..... that original fan will blow far more air through a larger pipe. Bigger pipe with the minimum slowest bends possible ....
Alec: Being unfamiliar with the blower + gas setup, what stops the air fuel mixture from mixing and igniting in that little vertical runner where its essentially an air fuel cast iron pipe bomb if things go wrong? Assuming there is a check valve in the gas inlet for the upstream, but does the gas pipe run inside the air pipe until they reach the combustion chamber?
Hi, i'm from Brazil, can you forge a cs:go knife? Please make a skeleton knife. Thanks.
Where's the California flag?
Been posting this comment to every videos since you put up the first flags.
Now that Matt is there you have a reason for a California flag.
Fan has to generate more than the 2 lbs of pressure the gas line is generating or your fan is just cavitating. Your pipe also needs to be adequately sized for pressure and flow rate.
I do travel construction and Milwaukee is the way to go!
