Alec Steele Blacksmith 2020 - Розваги
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This video began filming about two weeks ago so it's a little out of date in terms of the precautions and protocol we now have at the workshop in regards to avoiding the spread of the virus.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
When Alec is stuck in quarantine "im gonna buy this" ends up with whole new workshop
we have all done boredom shopping.
I know i did
@@Tinhead426 I mean I guess he now actually ended up with another workshop
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
"you could forge anvils in this thing." Sounds like a challenge to me.
Damascus anvil..that would be absolutely mind blowing
@@brocos 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.
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.
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.
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.
I've never forged, but I enjoy his content.... 😂
I felt that comment in my bones 😂😂
Same
I absolutely recommend you give it a try if you can afford it
@@Albatross0913 how expensive is it to start with like beginner gear?
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: final builds some forge doors.
Also Alec: look at my new massive forge!
Nathan Jaffrey next 10 part series building new forge doors for the massive forge
It will take another 2 years for new doors
The old forge fell apart inside, half the insulation crumbled away a few episodes back unless I'm imagining things again. Hence, newer, bigger forge...
@@SuicideNeil The newer bigger forge came as a package deal with the screw press I do believe. He wasn't necessarily looking for a new forge. Just happened to fall into this one.

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
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.
Dude, that's genius...
May have to steal that off you
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 know what's nice to see after watching this brilliant young man and his journey, It's the lack of mess you see on horizontal surfaces of doom as time goes on.
Kudos to you and the team Alec Fantastic as always.
Agree with this. You guys did a video about it once if u remember, but I would love to see a video about your practices in the workshop, how you guys run things. Maybe a behind the scenes or something!
Plumber here, those guys did an awesome job. Definitely use them for your future projects. The press tools are definitely fun to use.
Hey Alec I’m from California Full time Farrier/ Blacksmith. Hey thanks for all the videos you post if it wasn’t for that I would be going crazy watching the news during this scary times. Hopefully one day I get to meet you and your awesome shop. Thanks again!!
When you get the new forge up and running I want to see the biggest baddest axe you guys can forge.
I second this suggestion!
like escanor (7 deadly sins)
Or kratos's axe
The Kind it takes 2 people to lift, may have to make it in chunks
The way you mounted that plastic container onto the bigger blower was pretty genius
Alec: Lets turn this 90 degrees so it faces the other way
Me: I'm glad I'm not the only one making silly mistakes
tru but he can just hook up the other blower in serie and see what happends.
Surely he meant 180 degrees.
@@GilesBathgate im pretty sure he meant 540 degree
“Yeah mine runs on 75 pounds of boost due to my 220V twin electric turbski setup. “

Do you think it will fit in my Honda?
though that is a good idea, a compressor system may get the results he wants
i was just thinking, make a gas turbine from an old car turbo and connect the shaft to a huge diesel turbo compressor. only like 100Hp of compressed air
Excellent !! :=D
Hell yea brother
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.
Every part of this video was amazing. Loved seeing this all get set up.
Having spent a lot of time tuning motorcycle carbs, and seeing the effects of a good bell mouth shape for air intake, I'd assume that the small pipe and especially the reducer are limiting the amount of air a blower can push into it.
"This blower is hugely bigger"
Alec Steele 2020
Gunna need to make more forge doors...
Why does he need such a big blower? didnt the one it came with work?
Sounds like something Trump would say.
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.
Alec: make all kinds of adjustments because the handle got in the pipe's way
me, a genius: just cut it and make it shorter
or turn it sideways.. :))
Or bend it 90° in the middle of the rubberpart. Been there... 🤷♂️
You can unbolt the handle and and turn it around also........
@@thaavatar743 can't turn it sideways, by convention an open valve should have the handle inline with the pipe, and closed should be at 90 degrees. Turn it 180 and no problem
What Jeffer949 said...
Hey Alec! Just thanking you for inspiration and information! I finally put together a forge thanks to you, and I forged my first leaf today! I used your video on it, My first forge ever! Not the best but it was so amazing! Don't know if you'll see this but again thank you so much! I can't wait to make another tomorrow!!
Alec, you probably need to enlarge pipe between the fan outlet and the forge. Also, a swept tee instead of the square tee on the gas connection to the main pipe may help too

Thank you for asking. I'll be sure to tell my brother, a 1964 model year JWM in Toronto.
So no sir I'm not but I have been asked many times.
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 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
Thank you for continuing to give us shut ins something to look forward to. You and yours please stay safe and healthy too. We will see you on the other side.
I do love how the editor works the hits from the press into treble for the soundtracks, nice work.
Today: New forge
4 years later: still trying to build a door for the forge, because bricks are boring
In all these upgrades I think the best is the fact you didn’t just turn the valve a quarter turn out of the way and totally redo on it to make it how you want it
Yall's videos are an inspiration!
Did anyone else hear alec say "we need to turn this 90 degrees to make it go the other direction"
A couple of times.
I heard it but took it as "turn this 90° [elbow] and make it go the other direction" but maybe he meant metric 90°

You underestimate my power....
jk I would never dislike any of your videos
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.
As an aircraft mechanic those genie scissor lifts are a god send. Couldn't do much without them.
Alec, I spent a number of years working with fabrications that required blowers. I highly suggest you find a New York Blower (NYB) Rep in your region. They were excellent to work with and matched blowers to applications quite well. Their fans were beasts.

Hey Alec, that plug with one prong sideways is often used to indicate a '20 amp Required' 110 volt line. Meaning it is still a 110 volt AC device but requires a 20 amp breaker. I see it used on large multi-function copier/printer units.
I have to admit, its nice to see other smiths using natural gas. Reminds me of my first forge.
Isn't it fun when everything is like twice as expensive as you accounted for.
Yup that applies to pretty much any small Job you do
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
One thing I love about you, Alec? Your genuine care for safety, and for us, your metalworking fans, and that short little PSA about the fibreglass wool insulation being carcinogenic. And then there's Dude McBackyardFabricator that practices and teaches horrendous angle grinder techniques, sloppy welding safety, arc flashing their staff, and terrible workshop cleaning techniques, under the guise of "it's never been a problem.... yet". You care. And it's exactly what this generation needs to learn, to keep us all safe.

Also i do alot of gas sizing as well so this is very interesting to see how gas sizing is done outside of Australia. Always learn something new every video and i love it. Stay safe guys
Thanks for that warning about the exposed kaowool. Like seriously I had no idea it was dangerous. I will get mine covered up before i forge again.
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.
I believe it's 2 bar not 2 psi
Hate to play top trumps but i worked on a 1100bar uhp/uht nat gas resivour 😂
@@Carl2k7 1100bars... dear god that some pressure, you sure you didnt mean PSI? What kind of pipes even handle that? Second though what kind of connectors handle that!? O.o
Hellsong89 haha I wish I meant PSI brother, so thick walled super duplex using grey-lock hubs for the pipework and butech or autoclave fittings for connectors. Standard swagelock and NPT stuff is usually only good for 10,000psi
Alec: There are no WiFi connection in plumbing yet. Me: Laughs in Alexa activated solenoid.
You could have flipped the handed to the gas around
Thank you for continuing to prove us with amazing content. Keep up the hard work and stay safe.
Bernoulli's principal, Alec. Pipes can only handle so much flow for their size. If you need more air to mix with the fuel you'll probably need a larger pipe.
Forcing a larger volume of air through the same size pipe raises the pressure. When pressure goes up, volume goes down.
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)
@@roballen7899 a NOS system could work.
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.
I love all the new equipment in the shop. I cannot wait to see the size of the billets you can now work on.

About time!! Been going crazy with this quarantine!!!
Idea for obtaining more air for the new forge. Use an “intercooler”. Many automotive applications use it to cool hot (and therefore less dense) air into cooler (more dense) air. See Supercharging and Turbocharging. The more dense the air, the more air molecules available to burn, more/better combustion. Of course flow is important as well and you must have piping that can support the amount of flow you are generating. Piping size and change of direction impact this greatly.
Thanks Alex, great video 🤘

Alec:“Natural glass plumed in” 😂🤣😂🤣 min(15:45)
The vacuum blower seems to be a low pressure blower, more designed for high flow at low pressure.
The gaz adduction makes a backpressure that decrease the blower flow, that's why there's no big flow differences between full open inlet and squeezed inlet.
You have to increase the pressure (Delta P ) to increase the flow. Maybe try to link the blowers ! (serial link, not parrallel link)
Sorry for my bad english, I'm a Belgo-Novegian girl with big hammer! ;=) Love you guys, Axelle.
Bottleneck in the plumbing for the airflow, Maybe the original blower would be great if it could fully exhale.
This has become a dream shop for me.
Use an aspirator - you can increase the volume of air pushed into the forge without buying another expensive blower.
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
Those heads are mega press, which is for gas piping, propress is for water and plumbing, and zoom lock is for hi pressure lines found in refrigeration lines.
"Behemoth" is a new word, for me, on youTube. Kudos, Alec!
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.
Well considering you cant compress a liquid....hahahahah sorry had to. Last time I tried to compress a liquid I blew the piston out of a 50 mmcfd compressor at a natural gas facility. Found the head of the cylinder about 250 yards from the building and a large new window in the side of the building. The field was carrying over oil into the plant and the level gauge on the inlet scrubber had froze, so we never got a level indication that liquids were getting to the compressors.....oooops
@@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.
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.
Dude, Alec... Unistrut and 80/20. You should know these things for building any quick frame supports. Awesome products.
When you slammed that drill index shut and all the drills when flying I lost it lol. I have the same index at work and have done the same thing probably about 100 times. My response is typically not quite as polite but made for a good laugh. Love your videos and hope you guys are staying safe and healthy!
Since Alec has been in America, he’s learned freedomheight and how to “Jerry rig”. (More proper way to say it) 😉.
Forge door episodes: *exist*
Alec: We're doing a sequel!
For a short project, could be cool to see a soba-kiri. It is a knife for making noodles but it is a beast of a knife.
I like how the original forge's blower was just laid on that plate, but Alec made sure to make holes for screws and better fixate it. Shows how much he cares for a well constructed piece of equipment, not just put together.
Edit: I say that, and then Alec improvises an adapter for the test blower with a freaking bucket.
Should we expect Forge Doors: Season 2? 😂
"Turn it 90° up"
- proceeds to turn pipe 180° upwards :)
Dude uni-strut is the best!!! How have you never heard of this?!
I don’t forge, I work as a paramedic. But LOVE the show! Just wanted to say I appreciated you using the correct term of “less dense” rather than what more people refer to as “less oxygen” 👌🏼 precise. Gotta think of those partial pressures
It just keep getting bigger!!
*my friend screaming* That's what she said!!
Everyone: That piece of equipment won't work for sure...
Alec : Hold my coffee and my hammer, I need some steel, two rolls of duct-tape, 5 bottles of blue Dykem (not the red) and a lot of propane.
I think we can now all admit that Alec might be the lost son of MacGyver.
Raphaël Dapzol Or uncle Red’s son from the Red Green show.

Unistrut is the greatest invention. I know a chap who built his greenhouse from stuff that was left over from a site he was working on.
Unistrut is great stuff. I have used several thousand linear feet of it for rigging and mounting. Amazing for jobsites when you can't have much more than a porta-bandsaw. Unistrut, all-thread, and make-a-bolt kits is like a grown up erector set. A bit expensive in general, but if you don't have the realistic means of on site fabrication, its a life saver.
you Could forge an anvil in that thing.... care to demonstrate? Damascus 30lb anvil? mmmmaybe? gold filigree that reads "Steele" or something?!
hmmm!?! cmon people upvote how epic would that look!
I don't actually think he will do it, because he can't break it while straightening, so there is no risk for alec to ruin a 2 week project and its not funny
@@humwhatever185 i ldk, his last anvil took like 4 videos and it was just a small backpacker's model
Haha oh they'd find a way to snap it in half. You must be new here. Hahaha
Change the pipes for larger ones, your fan at high speed but low pressure.
Hi Alec,
I think i know what the solution is for your problem concerning too little air.
In order to get 100% of the capacity of your fan you need to make sure that the piping diameter matches the outlet of the fan.
With the small fan it looks like it has about 50% reduction in surface area and with the big fan even more, thus resulting in the same outcome.
You can test it yourself by feeling how hard the fan sucks in the air unrestricted and restricted. That's exactly how much air is flowing into the forge.
I would recommend cord covers for any cords you have going across open floor or taping them down because you are walking around with hot steel & an accident where someone trips on one would suck so much.
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 UA-cam!

you've got stronger blower but still the same diameter of pipes
THIS
From what I noticed Alex, between the blower and the Forge the of the size of the pipe reduces which would inhibit your air flow with your bigger blower.
Hope this helps
Nice looking good!!
