- Inert atmosphere for heat treating oven?
Don't adjust your TV, YOU HEARD THAT RIGHT!
I've wanted to try this upgrade since I first heard about it. Let's give it a try!

That oven must be wondering why all the air molecules argon!
The cockles are a blaze with pride my friend! Well done.
Bravo sir well done

funny so funny
Get out. 🤪
Tony: "No really, honey, these people will watch *anything*. I bet I could even get them to watch 2 minutes of a rabbit eating grass!!"
But it's from a collet!!😂😎👍👍
"Organic machining"
I watched it it was cute... I think Tony's plan is to attach the rabbit to the fly cutter and train the rabbit to eat grass from it so he can fly cut his lawn
Hell I've had 100 people watch a 10 minute long time lapse I posted.
@@eliworks8549 printing time lapses are entertaining. Watching all the structure being formed. Fun stuff. Now if more people would watch my video of a pseudoscorpion peeking out from a chanterelle mushroom that would be nice... maybe everyone is pretending not to be fascinated by him?

*Blacksmiths have left the chat.*
unfortunately it's true. first smithed "s" hooks I sold was out of some 1/4" stock that had been buried behind a buds shop for 10 years and she loved them and had to have them all pitted to hell.
Yeah I felt attacked lmao
The flywheel cutter explosion scared the rabbit out of me...
mine to but it wasnt expecting my pants to still be on!
I saw this comment RIGHT before the explosion 😂
Same - although MY new 'pet rabbit' is browner... And smells funny
Why was there a rabbit in you? ( ͡° ͜ʖ ͡°)
@@kingarthurthe5th I think the more important question is this: Why is there NOT a rabbit in you?
Why do I get the feeling that this whole video was just a sneaky way for TOT to show us his new rabbit?
trick... you forgot trick at the end.
It’s got me worried that the kittens were made into stew! 😱
Before it went I to the oven?😳
I wanna know how it came out white.
@@bradleystach6275 Worse yet, where'd he pull the kitten from??
Judging by how clean that bunny is, it may not have been the first take.
and how many rabbit does it take ?
You’ve never heard the one about how the bear asked the rabbit if he has problems with...stuff...sticking to his fur?
@@Scofflaw_k10 that's funny, it made me think of the same joke.
Nah. We have something better but similar to what you guys call a perma-coat or something. Always squeeky-clean... ;P
@@Scofflaw_k10 "One day down in the jungle" is how I start to tell it, and it is the the only joke I tell. Works best in mixed company.
Looks like the case of the oven is actually made from Undrillium.
@Peter smith and steel is heavier than feathers.
@@MaximilianonMars but only if you have a pound of each.
On top of it's heat-treated it is a heat treat oven. once it turns you need something to cut through the hardness.
TOT needs the Hardness Standards table for the different grades and types of : Undrillium, Unobtainiaum, Toosoftium, Badstuffiaum. I'v got one SOMEWERE in my old Gerstner box.
Man the rabbit really stole the show 😁
Especially since he literally just pulled it from his ass there...
It’s now the baby bunny show.
How come the rabbit wasn’t a brown bunny?

Finally I found another guy who puts his fly cutter in his cordless drill for squaring work on the go

Use it on the fly so to say lol.
@@michiganmoto7687 When I was first exposed to a Yankee, I was blown away... I still kinda want one. Perhaps one day I'll make that happen.
@@DavidLindes I got one at a yard sale, works but I never use it, just a novelty piece I guess. You can find plenty at antique stores or eBay, they'll cost a pretty penny though
With this video, you increased the audience in this house to 3x its original level! My bunnies actually sat and watched the last two minutes without hopping away, now they want to know when they can have collet greens of their own.
TOT's fingerprint removal tool at @10:22 made me cry from laughing so hard! I know it's almost a year later, but I STILL come back to watch this video for a laugh.
The idea of a fly-cutter in a handdrill made me laugh out loud.
yeah that one got me good
Requires a bit of a steady hand, but do-able.
No realy!
I've had some spade bits try and simulate how that would feel
I've accidentally made one while trying to drill a steel bar, I lose grip and this fucker was spinning. Almost lost a finger
I told my wife, he's easily the funniest machinist I've ever heard.
It's true argon is heavier but if you flip the oven upside down it nullifies the effect.
Don't do it! It caused my oven to float away!
Gonna asphyxiate the Australians if ya ain't careful
These 3 comments are the greatest!!!

Good to see someone out there still using one of those vintage dot matrix 3D printers. I have an old coal fired printer from the late 1800's...it was a barn find...struck gold that day!
My favorites - pulling the rabbit out of your butt, the flycutter causing an explosion, and the rabbit eating grass accompanied by threatening music. Tony, you never fail to surprise me! Oh - and the oven seemed to work pretty well, too.
It reminds me of the Jim Carey movie where he makes the monkey come out of the guys butt.
I hope he puts that poor rabbit back where he got him from.

I bet Ron Covell could make one of those tool holer racks using 'Rollation' and the hole drawing tool like in the bomber seat. I would watch that.
@@yetanotherdan Do his kids know the old man is doing experiments on the bunny, in the garage?
You should do a gag where you're still wearing work gloves and they make your voice sound muffled
You've got hardened scrapbinium, and a heat treat oven. Why didn't you make the first part into annealed scrapbinium?
I just posted this comment. So true.
The argon is heavier than air. It's leaking out of the oven through the steel casing and door. I recommend putting the oven door up if possible to reduce leaking. Otherwise increase purge cfh.

@@froop2393 It sure as hell cools down quickly too... and transfers it's heat to the air causing air to become lighter... overall keep in mind the diffusion usually argon just like any other gas will just disperse in air and you will merely start suffocating because the concentration of Ar is Already to high in the whole room... besides Argon is already in the air, it is just that the concentration is very low... I'd just be sceptical and take every precaution possible, most importantly install an active ventilation system in your garage...
An iron worker would just weld the door shut
Why not change how the over is oriented? Like with the opening upwards, like a foundry. There is nothing preventing this aaaaand once it is filled with argon....it just stays there.
You got me with the exploding cutter gag, made me jump!
Me too. It startled me.
Yup,,, same here
Blimmin heck! Just a bit!
Yep nearly brown 🤣
I've never machined anything in my life and probably never will. I still love this channel. I feel I'm learning things I can use later to tell other people that know more than me how they're wrong about machining but also I always come away smiling from these videos. Just thought I'd throw that in there among the pro's and machinist crowd talking shop.

When we use nitrogen to inert vessels in the oil industry we apply the gas from the bottom and vent the oxygen from the top.
You an always check this in your application by putting a lite
Match into the vented gas to confirm you are getting no more oxygen in the vent stream.
No we don't use this test method in our industrial applications
Imagine being at an event and seeing a pair of floating hands.
By the way, I'm surprised that rabbit wasn't brown.

Like that old joke:
A bear and a rabbit were taking a dump out in the woods.
The bear asks the rabbit, "do you have problems with poo sticking to your fur?"
The rabbit looks up and says, "uh, no, not really..."
The bear wipes his butt with the rabbit and walks away.
Note that the bunny is on a scotchbrite pad. It takes some work, but you can eventually get through to the base white rabbit. Necessary to get a good surface finish for bluing, of course.
@@Mishn0 still funny years later dad.
I've been working as a knifemaker a few years back and we also used Argon to flush the chamber.
From my experience there shouldn't be any damage to the surface layer at all. All we used to get was a thin matte grey oxide layer and no pitting to speak of.
This was easily removed with a few strokes of 400-600 grit sandpaper. This layer would be tough but thin and you could still see the satin finish from before trough the oxide.
I think time is of the essence here as the oxidation starts as soon as you open the oven door and the atmosphere disperses. Just move a bit quicker next time.
Also I'd set a higher flow rate and maybe you should replace your oil as it seems to have a lot of gunk in it which immediately bakes onto the part as soon as it touches it.
If you're not using proper quenching oil yet, try to get some that's specifically made for heat treating.
I'd also stay away from Nitrogen and just use the Argon. With Nitrogen the oxide layer always seemed to be a lot harder to remove given the same parameters as with Argon.
I can only guess but I think the outmost layer got partly nitrated in the process which may not be a wanted side effect...
This was my thought also. You could crank up argon flow right b4 you take the part out and have your oil right at the door. As an alternative I'm going to purge my shop with argon completely be for removing the tool from the oven. I love all your videos TOT. I'm feeling kinda sleepy, I think I'll take a nap in the shop.
To add to the whole proper quench oil idea, also keep in mind that some steels want a heated quench media.
@@alext.7313 AFAIK most tool steels do. When doing critical stuff we'd usually prewarm the oil to around 200°C. This also reduces warpage and probability of cracking.
@@joenicotera2991 Proper Nitration happens at 500-550°C, so at those high temperatures it's merely an uncontrolled side effect. When done properly your part shouldn't look hot forged at all but just have an even greyish coating all around. For the parts i usually do i can still fit precision ground pins to holes that were reamed at max. 0,01mm bigger without even cleaning them up. And no, a nitrated layer isn't always wanted, especially when you need your part (f.e. a knife) to conform to certain characteristics (e.g. toughness, brittleness, edge retention, etc.).
@@unr3al67 I can say that, to my experience heat treating a wide swath of different steels, it's close to 50-50. In fact there are many steels that want to air cool after hardened. To make it more interesting, some require some intense heat mapping to air quench properly. (Ie slow ramps down, weird stepped ramps with plateaus, etc...)
The idea that technological innovation has taken an object that could be made of wood in 15 minutes to 27 hours, not including the design aspect. What a time to be alive.
Also you could have purchased a child's step stool and drilled or melted holes in it. BUT, it's not about the journey or destination, it's about buying more tools.
The Rabbit bit was so precious, hey you, Old Tony, thank you for making my day better.... Cheers!
Wrapping parts in stainless steel foil for the hardening and quench will keep the scale away. The parts don't even turn black.
I was watching thinking, "Huh, my mechanics never seems to have scale." Now I know why!
You can negatively effect the quench, if you don't remove the parts from the envelope first (depending on your particular requirements)

Where are the cats???
@@JohnADoe-pg1qk We took them, ages ago, and you're asking NOW? Really?!? Once we've replace those punny cats with one of ours? Really?!? We did ask for a reward too you know? But no one answered. So, we sold them to SIr SIc. ;)
I probably shouldn't mention that he's actually petting his butt hare on camera then!
@@Hypercube9 Well, in a way, he is. But, to mention it or not is your choice.... Lmao!
Many years ago I worked in my grandfather's tool & die shop and we would wrap the dies carefully in stainless-steel foil before they went in the oven for heat treating. They were still slightly discolored, but when they were unwrapped they had NOTHING like the scale I saw in the last video when the tool steel goes in naked. This argon mod is awesome, but the old folks knew how to get stuff done too.
I regularly use A2 and I either wrap them in stainless steel foil or bags. If I do it well they come out nice and bright. A2 is an air cooling material. I leave them in the bag and before tempering in the kitchen oven they are at 62 to 65 HRC
That's how I learned to do it, with an added chunk of paper in the bag so it burns up and consumes all the o2.
4:30
That's a deburring tool! I used those when T was in my training workshop at school!
Tony said a nose or ear trimmer... As a joke. But i forgot the name of the tool, so thanks to be the only one to help.
@@moiquiregardevideo here we call it a monkey tail
I'm still wondering if he was being funny or did not know for real. I could not believe I actually knew what it was, considering I have about 0.5% of Tony's knowledge...

"scrapbinium." I'm gonna use that one.
Our rabbit graduated from eating collet grass, he now has his greens served in a ten inch 6-jaw chuck. True story!
The rabbits in my backyard only eat O2 sensors and various wires.
@@Hypercube9 so now I know what kind of critter ate my o2 sensor wires. Thanks
@@Hypercube9 are they covered with long point hairs ? for that variety also eats radiator hose's >can you imagine emerging from hunting camp hundreds of miles from a auto parts store ,and as cold as it might be , you have no coolant left ?
Noone gonna mention that he spent 40+ hours printing children's stools with holes in them?
That's the joke
0:46 learn to play with slicer settings and feed and speed
Optimizing your head speed, extrusion hight, etc greatly helps print time as well as not sacrificing fidelity by increasing nozzle size
Also you’re not gonna completely get rid of scale unless you’re going to keep it in a completely inert atmosphere including quenching but you’ve definitely helped a lot
Plot twist, the bunny is named argon and This Old Tony will be cooking with him later
Mmmm, rabbit pie

Someone once told me the key to making being human easy is make your screw ups look like you planned them.
You didn't run out of printing 'ink', you planned on two tone legs.
In that vein, I went looking for drill stops by ordering shaft clamps. The secret to my research was I ordered a bunch of shaft clamps by the OD, thinking it was the ID. As I was putting away the much too small shaft clamps, I noticed just how much they looked like the set of 'drill stops' I had bought from China via eBay 4-5 years ago.
What put a smile on my face was discovering the price of the shaft clamps was MUCH cheaper than even the drill stops when I compared the sizes in the set.
I love it when a plan comes together; even when I had no plan.

I bought the cheapest, single set screw, no split, Blk Oxide coated steel shaft clamps. You could go 'show boat', and buy SS shaft clamps.

It's funny you mention a "rotating hot end" for a 3d printer that's actually something I've been working on for awhile now, specifically to allow different materials/nozzle sizes/ temps/etc. Basically a microscope end, just with E3D V6 hot ends instead of lenses.
It is a cool design can't wait to see you finish it.
I've made a couple 3D printers with multiple hot ends for different colors flavors etc
@@benjaminwatkins7345 ya there are multiple ways to do it I just haven't seen one like what he is working on. And it is almost exactly what Tony describes.
Tool changer mods are a thing now
Makertech3d sells a switching hotend but the reviews aren't that great - and the switching with that one is only on one plane. Repeatability and calibration is a huge hassle.
There's some nice manually operated options though, xChange being the one that comes to mind first because it's a commercial product (kickstarter) but there are many opensource solutions on thingiverse and the like.
For fully automatic toolchanging, the e3d toolchanger / jubilee3D seems to be state of the art atm. Their couplings are being ported to different platforms by the community. Also a hassle to set up and calibrate but very precise and repeatable.
The worst part of 2020 was the lack of ToT vids, save us Tony more vids plz

Tony, I'm a big fan, your my favorite you tuber. Being a heat treater from way back I could write a book about this video. I enjoyed it very much and I won't be nitpicky about the technical errors, I know it is all in good fun. By the way Nitrogen will not work as well as Argon. If you would like to hear more I'd love to talk about it, metaphorically speaking of course. I also have a great project for you if you could let me know how to submit it. It would be too long to put in this comment. Thanks for what you do.
That humorous sarcasm is what made me suscribe. It makes for a more entertaining watch.
Next project: Tony makes a second camera.
"Buys" a second camera. Too many un-ToT components in a camera. Of course, he could always make a camera stand!
On the lathe.
Since argon is heavier than 'air', most of it is going to flow out of the oven as soon as you open the door.
Nitrogen will take longer to do that (since the air is mostly nitrogen), so you may get better results with the other gas.
Honestly, I've found that laying the oven on it's back with using gas helps the results, since opening the top doesn't let the purging gasses fall out onto the floor.
Argon is heavier than air, but it is fairly hot inside the oven, so maybe it is actually lighter than air in this case?

Hi, fair warning: The E3Dv6 hotend used by the Prusa MK3/S is close to being flow rate limited (cubic mm of plastic extruded per second) for thicker layer heights even with the 0.4mm nozzle, so with larger nozzle sizes, that is the bottle neck and will prevent you from deriving a good chunk of the speed advantage you could be from larger nozzles. But I am very impatient and an instant gratification enthusiast (who isn't?) so here is how to get around that, and some other tricks to reducing print time by a few fold:
1. Get an E3D volcano hotend. It screws onto the Prusa heatbreak and uses the same heater cartridge and thermistor, so it is a drop-in compatible upgrade. You lose a few mm of print height and you'll need to print a fan nozzle adapter to lower the outlet slightly (there are literally dozens of these if you look for volacno prusa mk3 on thingiverse - and you can print fine for the most part without it anyway). You'll want to get some nozzles for it too - 0.2mm to 1.2mm sizes are available. More importantly, the Volcano increases your maximum flow rate by 2-3x, which for layer heights and wider nozzles will cut print time by a half or third. Just make sure you increase the 'maximum flow rate' setting in the filament settings in Prusa Slic3r. The settings included are tuned for the wimpier E3Dv6. I've been using a volcano exclusively for years and besides a mostly negligible z-height loss, there isn o downside. It's just better.
2. Strangely, I never see much about this trick online but its a vital knob one can tune for 3D printing: extrusion width. Meaning, you don't need 0.6mm nozzle or even an 0.8mm nozzle to print line widths that wide. The only true limitation with nozzle radius is layer height. You always have to print layers slightly thinner than the radius of the nozzle (so 0.35mm is the max for 0.4mm nozzle). But when it comes to extrusion WIDTH, you can generally print up to 250% the nozzle radius without problems. If you look at the nozzle, there is a flat surface where the filament bead comes out, and that feature limits the line width (as this surface is what flattens the bead as the print head does an extrusion move). So you can print 1mm line widths no problem with a stock 0.4mm nozzle, and often you can go slightly wider but you start getting into the tolerance territory for the width of that feature so above 250%, ymmv between nozzles. I like to print with 3-4 perimeters minimum for strength, so a way to get a ton of speed improvement with little to no detail loss is to increase the line width of solid infill, infill, and perimeters while leaving the external perimeter width the default 0.45mm or whatever it is. Also, using line widths 1.5 times the nozzle diameter and wider tends to improve layer adhesion, especially for certain filaments like polycarbonate. The bead has to spread out and is thus smooshed against the previous layer with more pressure, and it is heat AND pressure that increases layer adhesion.
3. Not a tip per see, just a caveat: you'll want to bump up the hotend temperature when printing at 20-25+mm/3 flow rates with the volcano. The rule of thumb I use for most filaments is increase print temperature by 3°C for every mm3/s of additional flow rate above 15mm3/s. So for 30mm3/s, this means 30-15=15mm3/s * 3 = 45°C. So for a print temp of 210°C, this results in 255°C. This probably sounds really high for PLA, but when you're ripping that sweet sweet lactic acid out at 30mm3/s and you can see the spool just spinning continuously, it won't seem that hot anymore. The filament is spending so little time in the hotend that it is never actually reaching that temperature, the extra temperature is to heat it up faster so it still hits in the ball park of the intended print temperature by the time it exists the nozzle.
If all of this sounds like it might have a fairly serious negative impact on print quality.... it really doesn't. And you can really tweak these knobs without adjusting anything else and it really does generally just work. Obviously you will have the normal changes from thicker layers etc. but using these tricks won't really have an impact on quality beyond what you'd get anyway, and if for some reason you do, just back off the flow rate a little and you should be good to go.
Final double secret tip: if you're really nuts, E3Dv6 also makes something called the Super Volcano that is also compatible with the MK3/S. You will lose a lot of Z height but I mean, its a hotend that is undeniably what you get when you take the thermal limitations of print speed to its logical conclusion. The nozzle size goes up to 1.75mm (so, literally the filament diameter lol) and, well, just look at them. If you need all the flow rate in your hotend, these nozzles will put it all up in your hotend. ALL UP IN IT: metacollin.com/s/hvOxXgoUR02s.png

I skipped to the end. I was expecting all the grass is gone and just a pile of rabbit pellets.
@@randywl8925 Cheat. Go back and watch it all :)
@@honkynel I'll do that. Everything Tony does is worth watching twice. He is one funny guy. ...a very talented and smart funny guy
That rabbit was worth the price of admission 😂🎉
Very amusing. Tony should teach at a community college. An old blacksmith's trick for small parts is to cover it in a borax slurry. The slurry will dry out in the oven, and when you quench the part, the thermal shock will get rid of the borax. ^_* It only works for small parts, though.
Scrapbinium!!! Flipping hilarious!
10:20 This part so amused me that I repeated it several times and showed my family what I was laughing at.
The Hotshot 360 oven became the Subscribe 180 by the end of the video. Very clever! Great video.
you got me with the 2 mins of rabbit eating grass. Well done.
haha, loved the dot matrix printer sounds :)
Oh finally. Missed Ya, TOT.
The music choice for the rabbit scene is absolutely spot on!
How is it this channel about a fella just dinking around in his machine shop manages to be one of the funniest on youtube? I'll never regret subscribing, man.
That bunny was pretty white for where it came from. Tony must have a bidet.
And magically the oven was labeled with "subscribe 180"
I missed it
I actually flinched when that fly cutter went off!
I would love to see more videos of the heat treat oven. I’m praying for more videos on it. Love the channel. You’re an amazing cinematographer and machinist
The exposition when the cuter made contact actually got me lil
got me too, i went cold inside
Me too. I almost pi.... my pants. :-D
Hey Tony, not to be 'that guy' but you know you can just make a 1 mm nozzle right? Could even be hardened steel! After all, what's the point of a home machine shop if not spending 6 hours on a $2 part :P
(probably need a heater upgrade for that though, just FYI)
Just to be another kind of "that guy", be careful increasing nozzle sizes. Your hotend has a limit on extrusion rate, usually measured in mm^3/sec. Things like the Volcano hotend increase this limit. Not sure what your hotend is, but you can probably find the limit online and program your slicer to not exceed the max extrusion rate, but that will slow down the print again. There will be a point of diminishing returns without upgrading the hotend too.
@@samuraisystemsllc a second to this! I have a normal V6 hot end and a Volcano and I keep stumbling into the volumetric throughout limit on just a 0.8mm nozzle even on my volcano (I run speeds fairly high, its a 400x400mm bed after all).
Other people have tried that with smaller nozzles and ended up turning the nozzle into scrap. You also need a printer that can push that kind of volume into a larger diameter nozzle, otherwise you risk damaging other parts of the hot end.
@@samuraisystemsllc Looks like a PRUSA so it would be a E3D V6 stock...
I think its been said elsewhere in the comments, but for anyone that's interested in learning about 3d printers, the power output of your hot end DOES put a hard limit on the amount of filament you can push through your nozzle per second. At first glance, that makes it look like a big nozzle is pointless. The reason its not is because the printer only needs to dispense a certain amount of filament per inch, but it can't fly around corners in the print at top speed. Therefore, increasing the nozzle gives you lower print head speeds, meaning the head doesn't need to speed up and slow down for turns as much, so it runs closer to the maximum speed more of the time. (You also lose resolution though, so sometimes it's not an option. Holding out hope for that multi head attachment. Do it for the kids, Tony!)
Thank you for the rabbit eating, that was excellent. Be interesting to see if sitting the oven on its end so the door is at the top makes any difference, it would stop the argon spilling out any gap in the door.
Your sense of humor is perfect for your content, I just subscribed and look forward to watching more of your videos!
1mm nozzel yeah.. not on MK3 though.. you need upgrade the hotend to a e3d volcano or something... the E3d V6 it comes with cannot melt plastic fast enough to print with a 1mm nozzel!
I mean, you can just turn down the feedrate and print slower. (yes, this can actually get faster print times, see others below)
@@troy4393 which defeats the whole point in trying to speed up the print!
@@oderbang Well, to play the devil's advocate: your printer is rather rarely actually moving at the print speed assigned, because accelerations/decelerations take up the bulk of your movements. Consequently, if you double your extrusion volume and halve your max speed in order to maintain the same volumetric flow, you are in reality going to be printing significantly faster as your actual average speed can be much closer to your theoretical max speed.
Troy Dietz that would result in slower print time, so no Bueno.
An E3d Volcano upgrade option would give the results you desire.
When you said wire wheel the part, I was so awaiting the thud of the part flying across the room hitting the wall. You failed me TOT!! I shall not forgive this.
I was hoping he'd come back with a ground up nub of steel. "A little too aggressive on the wire wheel, I guess."
This video perfectly demonstrates the advantage of heat treating in molten salt.
LOL Love it ! The rotary deburing tool got me.
I really really appreciate you including all the things that seem to happen to me. Dull drill bits make you question whether you are doing something stupid. Mystery materials end up being incredibly hard to cut etc. This is me all the time.
That explosion actually made me jump 🤣
I sure wish we weren't just internet friends. Sure, I'd be that annoying "friend" who'd always come over and hang out at your garage, telling you that Meatballs and Christmasy Lights are so much cuter than that rabbit. It's the eyes you see, those red eyes creep me out. Unless it's a robot. Red robot eyes are cool!
I've seen many vids where the object to be heat treated is just wrapped up tightly and sealed in stainless steel foil?
Works a dream and just unwrap and reuse. Blackbeard does it pretty much every time.
I personally love the look of mill scale/quench scale on parts that aren't dimension-critical
...the scaley surface as it ajoins a clean, machined section? Unnggghh...
@@AHustleIsLikeASideOfFries I can't tell if that's a groan of pleasure or disgust lol
