I know you are just doing a “hey Man” job but I know I’m not the only one who would love to see you put that drop piece of tubing in your hardness tester and see what the actual rC is.
Great fun, Adam! As a science type, I love to find excuses to measure something. How useful would a hardness test be, especially in a few different spots? I suspect that with all sorts of exotic machinery being manufactured these days, a lot of rather funky steel alloys might be mixing into people's scrap metal bins.
Always fun working with a mystery material. Add to that an unknown insert. Nothing like stacking the deck against yourself. I enjoy your CNC learning, but I enjoy manual machining better. Thanks for sharing.
I am sure I am not the only home shop amateur that gets some satisfaction watching a PRO struggle as much as we do !!! Love watching you manual work, it's absolutely the best !
Adam, thank you for showing the screw ups. I learn a lot when you show the adversity and difficulty of the problem. So many channels don't show this kinda stuff. In the real world difficulties will be encountered so showing them is critical.
Those are the kind of videos I like. No fancy stuff, just real world scenario. I'm a machinist myself and I felt little less alone by watching this video cause it shows what most of us have to do every single day. Solving other people problems by having to have more problems
Abom I know how you fill i was a tool and diemaker and machinest for 40years.. 83 years old now. i whatch all of your .love them. keep sending. vidios.
My eyeball sez that stuff was machining like a 4140HT in the lower Rockwell C range, or something similar. No forgiveness but always finishing beautifully. Decent carbon and alloy content, not enough hardness. Gooey. Prayers to the guy who has to weld it.
Way back in the day I used to make hooks and chains for GM. We cut 1 inch hot roll to length then forged them into hooks. The hot roll started having hard spots. Literally hunks of carbon in the rod. Had to use an abrasive saw to cut.
Good content Adam! Keep it coming. As others have mentioned as well, I'm definitely partial to the manual work but I also understand the need to have CNC capability in today's world.
Hi Adam, greeting from "across the pond". Congratulations on an absolutely superb bit of turning and problems solving. Commentary "just the right amount", (short and to the point), with plenty of good working input. Lovely to see some classic turning again!.
Test for Hardness on the waste end of the one with saw cuts in it. Maybe wrong shop. On the bandsaw carbide did it. How about a skip tooth or dual pitch - fine and wide gullet. I bet scrap steel and has bearing races that melted in to make the alloy harder.
Years ago I asked a machnists while making cuts in angle iron some sections took twice as long to cut thru. Told me angle iron is mostly recycled steel and anything goes into the steel furnace .
Why didn't you use your hardness tester before machining the material to see if that was within spec for the material? Couldn't that impact the welding? I'm not a welder is why I asked.
Material hardness is only an issue when welding if you’re trying to retain the hardness afterwards. The process of welding is going to heat the material up past critical, which will remove any hardness wherever the bead penetrated. Ductility can be a bigger issue, which is why pre-, interpass and post-heat in things like cast iron are so important.
I use a casting cutoff blade that is special made for cutting castings ,they work great on stuff like that, i have been using one for over two years and use it just for tough stuff.
The need to leave a proper finish can be appreciated as somebody who loves machining things (I’m not a machinist) but, as a welder, there comes a time when it’s disheartening to weld something so beautiful in place…. Just knowing it’s going to be destroyed when the equipment starts getting used. Kinda like watching a veterinarian examine cattle leaving his Rolex on without gloves. Lol
Adam "I am not one to tell somebody what they're doing wrong" well said. After all there is no need for you to do that, you have all the expert commentators below to tell everyone and anyone what is going wrong. LOL
He's been around a lot of journeyman machinists all his career and has learned not to presume he knows better. He knows there's often hidden information and something new to learn.
@@ellieprice363 Ive seen it with bandsaw blades and circular saw blades. There is no reason when putting on the other replacement bandsaw blades they were then on the correct way, if you dont know the difference in the first place.
I doubt it, sounds like the guy has a good bit of experience and then to install them wrong 3 separate times seems unlikely. But you never really know what people will do
I've worked with enough recycled steel to learn that unless it's certified to be a particular grade, there are both ridiculously soft spots and then, there are some hard spots that will ruin multiple brand new drill bits within seconds. I imagine the same is true for cutting blades.
we cant get 4140 hollow bar here in Aus but even at that it would still cut easy on a bandsaw. interesting to see what happens when it trying to be welded ?
Greetings from England big man. I've been watching the channel for years and i don't think I've seen you this frustrated! Or as close to frustrated as you get, possibly the most laid back guy on yt. 😎
Something that I saw and wasn't sure if you'd run into it. The hydraulic/air feed on these saws have a place where they drop when they are sitting on the stop. I usually had to push the saw back up to it's full height, and then let it go. This worked when the saw was set to cut a heavy feed rate so that it wouldn't crash the blade. Basically it would preload the hydraulic/air cylinder to keep it from dropping the blade onto the part. Kept me from chewing up blades and still cut fast.
If you still can, please do a hardness test on the steel. I know nothing about machining besides what I've watched and seen, but to my musical ear that sound was off from a normal lathe work. There was like a high pitched ding in there and normally when watching and listening machining the cutting sounds constant (as one would believe a material be that's all the same composition). I'd like to see the hardness from both OD and the cut itself, just because curiosity.
we have been getting lousy 1018, really ductile wont break a chip. finish is great but its giving us a ton of grief with our iscar dr drills not breaking a chip, which normally cut great with fantastic chip control. we think its metallurgical, low sulfur and high aluminum content seems to be a recurring theme in the stuff that wont break a chip, the "good" stuff is high sulfur and nearly no aluminum
I am a factory Iscar Rep in Southern IN/Kentucky. IC8250 is a great all around turning grade. Have you been able to try any of our newer F3P and M3P chip formers? They are great for chip control depending on your application. Your area Rep should be able to get you some samples. If not, please let me know and I will send you some! I love watching your videos!
You (and your customer) have a material problem. I would guess that stuff is rC 45. Did you try it on a hardness tester? I wouldn't weld it without further identifying the material. I'd expect it would Crack under weld without 700⁰ preheat.
Adam, you might (this is just a suggestion) want to find a cheap and slooow cordless drill and hook it to your compound feed. It makes for easy smooth long compound cuts.
I use those YG inserts and I don't have a problem. I had similar strings on a piece of unknownium the other week but increasing the feed solved the issue. I don't get as upset as you Adam when I trash an insert and I pay for mine.
His whole shop is sponsored, that’s why he always trashes the competition. He said himself that the feed rate was too low. But did he change it? No. He needed to make the other inserts look better.
@@kumoyuki watch his videos. Whenever he gets equipment, he always makes a video about it and says “my friends at so and so sent me this…” Now if he can get his AC, his welder and other things like that given to him, what makes you think he can’t get inserts for free?
@@SergioPena20 In fairness though, I have known people from the American South that speak that way about literally everyone. It's arguably circumstantial, but I was wondering about something more concrete
@@kumoyuki Most everything he has including his CNC machines he has received for free. Everything @SergioPena20 said is correct. Sorry to say, but he is nothing more than an influencer these days.
That crusty scale on the OD looks like a real blade eater. It sure cut good, but my ears hurt through the TV. 😂 The teeth unzipping on a blade is a real phenomenon. As soon as that first tooth goes, the next one gets slammed and starts that chain reaction and all of the sudden you've got a blade with six halves of a tooth left. I'd have gone at those embedded teeth with a shark wheel (tiny abrasive cutoff disc) in a die grinder
Sometimes as a job trickles down to the Machine shop, the shop of last resort, it's the worst of fixing the previous fixes before actually doing the actual job that the part needed to begin with. Fortunately, Adam cut his teeth on just such jobs, all the "getter-outs" and "hey man" jobs that come to live or die on the machinist's job shop floor.
That material behaves a lot like 4140 or similar. Not saying it IS that, there's other stuff that also makes similar chips. I machines something out of an old car hub, that I was told would be 1090 or something like that, and gets a very nice finish, but chips that are very stringy.
You should use high magnification to look at the insert to see what effect that steel had on it compared to what you normally use. It would be interesting to see.
I run alot of tubing that looks like that, its called 4140 HRHT on the sheets I've seen. I think that means Hot Rolled Heat Treated, I do know it's plenty hard when I run it, I usually have to run it around 375 Surface feet it seems, taking about .500 off the diameter per pass. I use a Iscar 643 8250 insert with good results but I use the 432 8250 alot as well on other stuff. This is a aircraft tail wheel fork spindle housing I machine lots of.
I was running some stainless at work the other night and out of no where it was tearing up inserts every couple parts and random as heck. It had some hard spots in it i think. Crappy metal.

This video right here is the kind of stuff that will keep me coming back to watch your videos! Thanks for such an interesting video...
thanks for adding the sound the saw makes. It helps hoby machinist like me.
Since I’m a professional video watcher, I’ll say you did a fine job!! Love watching you work Adam!!! Nice job!
Awesome a man who takes pride in his work takes pride in himself

Thanks for posting these videos. Even though I'm not in the trade there is still knowledge here that crosses over!
We got all these expert machinists up in the comments yo
Definitely enjoyed the video. Thanks as always for the good filming.
Nice job work video. Thanks Adam
Counterfeit blades? Seriously the number of knock offs in every market, including materials like titanium is scary.
I know CNC is a game changer but this traditional machining is far more interesting to me. But then I prefer steam engines to diesel or electric.

I wonder if they put the blade on backwards
No. You’d have to flip it inside out which would be almost impossible with that size blade.
Good to see a job where you make the best of not-so-great starting conditions. And I always enjoy seeing manual work when it makes sense. 👍

Did you use your Rockwell test to see how hard it is
Questionable Material Steel vs Abom with a carbide blade...yeah...I am backing carbide here, nothing beats carbide!
You did good Adam. Yes I did enjoy your videos and as usual thanks
Best Abom Video In Ages!!!
THIS is quality ABomb material!

Bed frames. They are the worst.
Rebar is the worst.

hardness of the material will definitely change the welding parameters, you are correct
Thanks for verifying that for me. Ive done a few tack welds and run a couple of beads, thays it.
The hardness tester people weren't sponsoring the vidio the band saw mfg was

that mystery metal your buddy supplied you to be used as weld on 90mm pin bosses is probably some form of stress proof material....

This is the kind of Abom we come for. Thanks, Adam!
That alternate/extra ending was a nice touch.
Right tool for the right job

That's what I'd call making sheet metal the hard way!
Its unreal that blade isn't even deflecting all over the place. Love the look of a hefty, laser sharp cut of hardened steel !
Elephant in the room, the blades were put on backwards obv
I doubt that anyone would be that dumb.

hardness and PMI would answer a lot of questions for sure
pushing saw to hard or put the blade on backwards need to try the new cert wita that speed and feed ,that your cert required
Oh man no kidding that carbide tipped band saw blade is screechy 😖, I could hear it way over here at the California Oregon border! 😂👍
Rockwell test ? Looks acts hard when machined to me.
Nice initial break in.

I think he likes to 'feel' the cuts. He's been doing this a very long time, and can do some very nice and smooth manual movements.
Good vid. interesting see not perfect stuff and ways to sort it.
Could it have been tool hardened from a dull blade?
WOW! That is the most riled I have ever seen you. 😳
It’s a testament to how seriously you take your art! 🥷
A master machinist at work. RESPECT! 👍
Cut it using an edm. I'd like to see a Rockwell test on the material.
Yup. Didn't he buy some fancy hardness tester a while back - or was that Keith Rucker?

yes I enjoyed your video. thanks Adam
I thought you had a hardness tester.
I guess there was some stress in the material that clamped down on their band saw blade causing it to bind up and break teeth?
Where's the finished Hardtail Vise? Love that project!
😢 You could get a saw blade welder for the shop and save some money.
Enjoyed the show and keep em coming.
try the tungaloy AH120 cnmg inserts, theyre great inserts.
Most excellent.
One of the few times I've heard Abom swear...
If sections of the part were work-hardened from the band saw, doesn't that mean, for sure, that we're not dealing with mild steel?
Great stuff!
I was running some stainless at work the other night and out of no where it was tearing up inserts every couple parts and random as heck. It had some hard spots in it i think. Crappy metal.
