Making NEW Pins for Earthmoving Machinery | Machining & Welding

These pins are worn out so we are making new replacement pins! We’ve got 2 big bucket pins from a Hitachi ZX670 Excavator and 2 pins from the ripper bed frame off a D9T Bulldozer. We show the step by step process of making the new pins. We start with machining the plates off the old pins before machining up the new pins using induction hardened chrome rod. The D9 dozer pins also need deep hold drilling and tapping for the grease holes before using the milling machine to drill a through hole for the grease channel. We finish up the job by welding the plates onto the new pins.
In this video we are using:
- Hafco TM-26120G Centre Lathe
- Hafco BM-63VE Milling machine
- WIA 500i Weldmatic welder

It's always cool to see just how much difference there is between hardened chrome and the base metal. Even the ceramic inserts, as much as you baby them, have a difficult time cutting through that induction layer. That's probably my favorite part, but watching you cut through the old welds and recognizing when to stop is pretty satisfying , too.

[@josemanon6295]

I like you always use the crane instead of doing "burradas" (big efforts) your body will thank that in the long run. And that is "educational" for wievers!.Cheers fron Spain.

Best part of the editing is she knows when to speed up certain parts that are highly repetitious and we've already seen. When a new process comes up we haven't seen she slows it back to real time. That really helps it from becoming a 2 hour video without missing anything. That only comes from experience. And Curtis is his normal awesome self.

This channel in my opinion goes against logic. It is a very successful channel based around a very specialised subject. How many people know much about this field of work. Yet week in week out thousands tune in to watch. And now know 100% more about the subject than they did before. Which is still not a lot. For me it has four components that keep me watching. Interesting work. Combined with the description of what it is for, and how it is used. Fascinating. The execution of the fabrication. General quality of the work. The camera work and editing. Has to be among the best of the KZbin channels. And last but not least. Homeless the dog. Security and chief mail opener. It would seem to be a winning formula. I enjoy and appreciate all the effort put into these videos. And glad that so many others do too.

Even if this a common job. You give top quality with perfect welds. You don't kid when you say harden face. Karen is working hard to get the angle to video and sharp editing. Now tools down, cold beer in hand.

[@TSorovanMHael]

The lack of preheat on stuff that big, on a material that's easily induction hardened is a bit concerning to me, but they may have edited the preheat step out. Typically you'd want to preheat to 270-300°C. This is because the heating and cooling cycle in welding is pretty similar to the induction hardening process. So you have a risk that the heat-affected zone next to the weld becomes extremely hard and brittle causing subsequent cracking . Preheating the material slows down the cooling rate making the HAZ softer and more ductile.

[@urbanwillis2212]

Hey man I spent my 18th birthday drilling 7/16" (bananas) holes/water cooling passages in plastic injection molds with standard twist drills anywhere from a few inches or up to 24" deep (short of drilling into the cavity in the mold). It was CSM2 steel and would work harden in a heartbeat. Then it was hell to drill the hole further. With a little innovation the shop engineer converted a Lucas horizontal boring mill to a gun drill with a high speed spindle. With the twist drill it was a thousand trips into the hole and then drag it out to clear the chips. On really deep holes I silver-soldered standard 7/16" drill to drill rod and that was even more trips in and out of the hole. I had to learn the trade the hard way and that was the rude awakening in how to actually work for a living. You remind me of the old time machinist that taught me the trade and me as a 50 year younger man. I enjoy watching your videos and hope you will continued doing them for a long time to come.

Having a parts rotator definitely helps a lot. Also helps a lot when you use 10-15% CO2 instead of the generic 75Ar/25CO2. Welds tebd to be cleaner and less oxidized. He's running it in pretty solid "spray transfer" settings which explains the smooth finish and low spatter. The majority of welders out there don't know how to setup spray transfer.

[@Gena_1309]

Спасибо. Как всегда все на высшем уровне.

[@sadlerbw9]

That hard turning is crazy. You can see that it isn't so much cutting the metal as pushing on it so hard that it melts, and then scraping it off! It was also interesting how 'squeaky' the stainless was when being cut in one of the recent videos compared to these pins.

[@TSorovanMHael]

It doesn't get hot enough to melt. It merely gets up to about dull red heat. Sometimes if the chip is thin it's enough to cause it to catch fire like steel wool, and it starts glowing bright yellow as it burns. Heating at just below red heat causes a phase transformation in the material converting some of it into a different crystal structure which is much softer. In other words, it reverts or erases the induction hardening process. Typically after heat treating a high carbon steel, there's a "tempering" step at about 300-400°C for and hour. This softens the material a bit to avoid excessive brittleness, making it tougher. But if you go above 400 the tempering process starts progressing much more quickly and becomes more dramatic. Near red heat the tempering is almost instant, resulting in material with the same hardness as the relatively soft interior of the bar. Same thing happens with drill bits if you spin them too fast or don't use oil, they overheat then the tip rapidly softens. Then they stop cutting and resharpening is futile. You have to use a cutoff wheel and chop a chunk off the end, then totally regrind.

I have nothing to do with turning, I am an electronics engineer, but I understand perfectly well what difficult work you sometimes do. I have a lot of respect for people like you Curtis. Be healthy !!!

You do make things look easy, but you spend a lot of time learning each part of your job . Great work each time too. God bless old man cliff

[@chadkennedy529]

Coming from somebody that grew up welding and lineboring equipment for decades, Curtis is a wildly intelligent guy. Everything he's doing would take your average welder/ machinist 3x longer to do any of this.

This was AWSOME! I used to sew but always wondered how the stitches held. I sewed on my merit badges (badly) ,then got better when my mom said " you need to learn lots of different things in life. ( I'm 59 now ) My kids and grand kids can't believe a MAN knows how to sew. The main comment I want to make is, the model you made was what got me. After all these years! Lol Thank you!!

When I had pins made, I'd often have them made an inch longer with an extended taper to make them easier to get aligned into the holes.

Nice job guys, those parabolic drills are great for deep holes, I've used a gundrill before but they're expensive and without the high pressure coolant it's no quicker than a Parabolic one

[@muchopomposo.6394]

Excellent, job..! Here in the UK, when Friday comes around, I'm up, washed, fed, a few jobs done (I'm a retired old geezer) I switch my phone on, and look for Kurtis, Karen and Homie's latest video... Aaah..! All is right, in my world, for a while, anyway..! 👍🏻

[@zachyoung4651]

I plan to open a small machine shop in a few years when I retire. I will be 45 and it’s been a long time coming. Really glad I found your channel and enjoy the content. Thanks

[@CuttingEdgeEngineering]

awesome mate all the best with it! 😎👊

[@michaelguinn5736]

Morning Kurtis!! Very good video, as I've mentioned before I work for one of the big three here in America, we do suspension & drivetrain development, we strain gauge drive & axle shafts, shocks etc. I shared your video with our consumables coordinator to see if he can order some of those Parabolic drills....be safe!!! God Bless!!

[@UKDrew]

Awesome as Always..... Pleasure to watch and learn.

[@CuttingEdgeEngineering]

Glad you enjoyed it

Incredible to see such a well used looking forklift with a backup alarm that still works

Hey guys i just want to tell you agian that you have one of the best channels on youtube. I look forward to your new episodes all week long. After my car accident ive been pretty much immobile and your new episodes on fridays signify another week down and another week closer to being healed. You guys have become part of my healing process and I can't thank you enough.

[@CuttingEdgeEngineering]

Hey mate we hope your recovery continues well for you and your back to full health soon !

[@BenS3.]

@@CuttingEdgeEngineering thank you! It really means alot to get a reply from you guys. The hardest part of my recovery is not the learning how to walk again it's not being able to work and provide an income for my family. Im a carpenter by trade, machine work is something I've always wanted to get into it is fascinating to me. I've tried watching other machinist channels on KZbin but none of them have what you guys have. Some people over explain and talk to you much some people don't talk at all. You guys have the perfect blend of useful information, entertainment and professionalism. Not to mention the excellent editing and of course Homeless! You can never go wrong with a good dog.

[@bandeano3870]

greetings from belgium, you are very skilled i am a bit jealous

[@CuttingEdgeEngineering]

thanks mate, just having a go still got plenty to learn & improve on 😎👊

[@macedindu829]

It's funny that all this stuff are for these huge industrial machines, yet I often find the materials shockingly beautiful. They're truly modern wonders.

[@bostedtap8399]

Love the Tailstock Cam 📷. Great job guys, blooming heck 1200 rpm on a lathe that big 👏. Thanks for sharing and have a great weekend all.

[@wb8ujb]

You three always make my day! Thank you so much for the video. I'm impressed with the hardness of those rods when you're cutting them. Good Day my friends.

[@MrCirqueMaudlin]

[@CuttingEdgeEngineering]

Hey mate thanks very much for taking time to watch we really appreciate that!
