Precision Line boring a GIANT Mining Truck A-Frame! | Sir Meccanica WS2

Watch as we tackle this challenge! We’re boring out the eye of a huge A-frame from a Caterpillar 789 dump truck. This massive component is critical for the truck’s operation, it connects the rear wheels to the chassis and we’re aiming for extreme precision! We're using our trusty Sir Meccanica WS2 portable line borer to bore out the eye to precise tolerances, but the extremely hard material is putting our tooling to the test. Watch as we battle through insert failures to get this job done!

Best channel on the internet!

[@CuttingEdgeEngineering]

Thank you so much!

[@norwegiangadgetman]

Best machining channel, yes, but best overall? nope. That would be 'Escape to Rural France'.

[@mattatstrat]

@@norwegiangadgetman REALLY! LOL

[@johnjay5143]

On machine work, all kinds of fabrication, machine repair, tooling etc. it's by FAR the best . Also, the comedic outtakes . lol

👋 Thank you Karen for not using super-shaky-cam and fast-zooms like a lot of other youtubers do these days! ♥

[@kubacube342]

Homie is for shaky cams!

[@gorillaau]

​@@kubacube342Has that camera gone to the dog? :-)

[@CothranMike]

Personally, I herd cats (2) and can applaud Karen's efforts to direct her subject. Compared to my cats, Homie is so well trained I am envious and I am going to stop pretending that directing cats is a real choice for me. I'll just capture whatever they will do, cute or not so cute.

She's pretty much like Kurtis's eye for detail on camera ... Perfect . :)

[@alexanderreid465]

Never underestimate your ability Kurtis, you have all the correct gear but you are a real craftsman when using it, great camera work too Karen, I really look forward every week to watching you both or should I say the three of you, I am 78 years young and learn new things watching you work, thank you.

[@richrdlewis6278]

That milk crate upgrade was worth it just to see that smile. We need a smile like that at the end of every video.

[@woodycolin]

It needs an engine 🤣 and is one drawer allocated entirely for 10mm sockets?

[@paulhirst3548]

@@woodycolin Don't give the guys at Grind Hard Plumbing any ideas.

[@donnienicholson6062]

@@woodycolin That's sadly true. I bought 10 13 & 10mm sockets years ago and tried to keep up with them but it didn't take long for them to vanish. Pipe wrenches and Channel Lock pliers look rather eerie sometimes.......maybe they eat some sockets when the box is closed but don't like other sizes.

[@yellowzt]

Never mind the engineering drama, this is some of the best video work on KZbin, great closeups this week. Thanks Karen and Kurtis for great content each week

[@CuttingEdgeEngineering]

Glad you enjoyed it mate

[@JohnDoe-bd5sz]

Just imagine being the poor guy that has to fit that sleeve, the grease hole must align perfectly i would imagine. :)

[@CothranMike]

@@JohnDoe-bd5sz I did not see any hole in the sleeve, I imagine that will be placed after the fit up, which is standard practice where I live. Come to think of it, I saw a groove on the outside, that will allow any grease to travel to the other groove in the ball.

On something this critical, take a 6mm plate bolted to the face with the bolts holding the boring jig. This plate would be machined prior to entering the actual part bore giving you a “test area” to ensure the bore is correct. Really enjoy the quality of all the work both of you do.

[@RekimNZ]

Nothing better than coming home after work, to sit back relax, and watch another awesome engineering video from CEE 😎

[@mapo5976]

Red October "Now I become flame hardened TCT, destoryer of inserts" or something like that fromthe ancient Hindu scripture as quoted by Mitsubishi Heavy Industries. Kurtis as Openheimer, a man beyond his time, beyond his contemporeries. Which presumably casts Karen inthe role of Einstein.

[@Peter-gi3re]

@@brianferguson8380 Based on some of the price’s Kurtis has given on other stuff this major component could be 500K. The whole time I was thinking …… what if he goes too far …… how would you salvage the job.

[@docfarl]

That's a compliment to CEE, for making it look simple and straightforward. Getting a 0.13 mil tolerance on that kind of boring, with no second chance if overshot, is near impossible for a lot of people. Guess that's why the client didn't take any chances to do it in-house and sent it to Kurtis.
