Machining a new Hydraulic Cylinder Head for CAT 651 Tractor Scraper | Part 2

This video is Part 2 of heavy duty machining a new hydraulic cylinder head for a CAT 651 Tractor Scraper apron cylinder. In this video we are machining the 2nd side of a 140mm chunk of steel plate. We are machining the internal seal grooves and boring internal diameter for the wiper seal before lots of interrupted cuts and chip breaking to turn down the outer diameter. Then roughing down the centre for a 45 degree nose taper before the finish passes. The cylinder head is then setup in a Vertex rotary indexing table on our milling machine to drill the 6 bolt holes. The part is completed with glass bead powder blasting for a satin finish.

I see 2 sets of skill here. The obvious is that there is a very skilled machinist working here. The less obvious is that the camera operator is really good. Smooth, gets nice shots, shows the process. Team work. Ver' naice!

When a machine part looks like a piece of art, you know the man making it has mastered his craft

It is a delight to watch a skilled craftsman such as yourself create. Thank you very much for sharing.
It is genuinely appreciated.

I never tire of your videos turning raw steel into precion parts and works of art.

[garyrigoni]

just watched your video and i was so impressed with your skills.i am 65 and have seen some trades decline due to automation.great to see a young bloke keeping the trade alive and to such a high level.well done

[jwooten]

I knew there were super well-trained machinists in the world but I had never seen one before thanks for showing me that you can do factory production Quality in a small shop .

Make me feel good to know we have such skilled people in Australia be safe robert

[Hightower]

Im glad you are using the metric System 😃 greetings from germany

Lovely work mate, the blasted piece in the final shots looked like a 3D rendered model! I really like watching rough chunks of metal turned into pieces of art like that...that would look good in any modern art gallery!

Hello from Washington State USA! I love your videos; I just wish there were more of them, and they were a bit longer. There's something magical about making something useful from a raw block of steel. I was a machinist back in the late 1960s through the 1980s, and I especially enjoy that you do all the work from lathe to mill to welding.

I've been watching your videos/educational tutorials for over a year now. I've been catchaing up on the videos from three years ago and a came across these four year old videos. The change in video quality is amazing, it's like watching a silent movie :). Homeless wasn't nearly as spoiled either. I'm not a machinist, but I've learned a lot watcing you. I have had machine work done occassionally and I'm much pickier about the work now. I do weld occassionally and like watching your technic.

It's always a surprise when I find I missed a video. You are at the top of the list.

[peterparsons]

Excellent work, lovely to see somebody that still has the manual skills... respect from a lifelong machinist and retired heavy plant guy

[olemerrild]

I like the Way you chainge betven slow and High speed clip.

[ezybroK]

Just landed myself an apprenticeship doing the exact same work you do, well wouldn’t trust myself just yet to be this good haha your videos are amazing seriously I can’t go to bed without watching one😂 hope to one day be at your level mate👍🏽 and I love the revolving tailstock chuck

[the_millwright]

We do cylinder rebuilds at work but get any machining done offsite. Great to see how it’s all done. Look forward to more videos!

[davesalzer]

Those big ribbons bring back painful memories. Beautiful part.

[HeicoFeenstra]

....Homeless seems impressed in the last few seconds! He knows craftsmanship when he sees it! Keep up the great work! Both machining and the videos....

[garyjarvis]

Amazing to watch the amount of metal coming off of the blank. That lathe was taking out metal like an ice cream scoop from a container full of vanilla. Fantastic work!

[Casull]

Great use of the annular cutter for the flange holes!
