Machining a new Hydraulic Cylinder Head for CAT 651 Tractor Scraper | Part 1

This video is Part 1 of heavy duty machining a new hydraulic cylinder head for a CAT 651 Tractor Scraper apron cylinder. In this video we are machining the first side of a 140mm chunk of steel plate. We started with drilling out the centre hole then lots of interrupted cuts and chip breaking to turn down the outer diameter. We then machine a recess groove before boring out the centre hole and machining the internal rod wear ring groove.

It would be interesting for you to do a video telling us about your story and to maybe do a shop tour going over your machines/equipment. How you got to where you are. Like what training you have? How did you grow a smaller shop into bigger shop? And any tips for people trying to get into the trade and start their own shop. Thanks!

Took machine shop in high school worked in a factory doing titanium bulkheads for Phantom jets for Vietnam!! 747 landing gear, wing spars etc.. Your videos bring it all back! Can smell the coolant and cutting oil!! Love watching them!! ☮️❤️

The camera work so far has been amazing thanks to whom is behind the camera nice steady clean shots .

I'm not sure what sound is worse, finger nails on a chalkboard or the sound of the cutter on the uneven sides on that chunk of steel.
I know nothing about machining yet find your videos incredibly entertaining and can watch for hours. The parts you repair and create are HUGE compared to others!
Keep up the great work!!!

[DavidLindes]

Watching those chips come off and then turn blue after landing (9:52) is a trip... would love to see a slow-motion shot of that!!

Love the always observant safety officer!

Great vid! Just listening to the music of the lathe and cutter is all you need. Got my machining fix for the day!

[JodyMackin-wg]

World need more safety inspectors like your's. ❤
Great video, thanks!

[MrArtVandelay]

When the work spins rather than the drill bit, you really get to see just how a twist drill works. I am amazed you can keep a sharp edge on these bits, tools and end mills.

I've seen the sketchiest interrupted cuts on this channel and you guys always do it so well.
Love it!

Lol. Safety office on duty.
This has quickly become my favorite machinist Channel.

Great video, just miss you walking us through what you are doing. Always helpful for us rookies.

I found this video after viewing something else. The videography three years ago was excellent and even better now. I was able to follow along and am convinced of the professionalism you both put into each video. I will say I appreciate the narrative now because it makes it easier for a novice like me to understand the process at hand. I also enjoy hearing Karin comment as well. You both do an excellent job and like a fine wine you both get better with age.

Served my apprenticeship in the early eighties manual machining large components for marine and base load diesel sets for Mirrlees Blackstone in the Uk, this is great work lads I miss it

[Todd]

Respect 🫡
I decided to watch a old video.
I am so close to getting my own CNC shop going man… this summer the snow will melt and I can’t wait… when I retire I am going to go to Australia it looks so beautiful and all the birds seem so awesome.
Best life to you guys.
I have 2 dogs just like yours no one wanted the killers but my family loved them all the same and they are perfect just like your dog is.
Take care of yourself.

You mentioned not leaving the key in the chuck Pandit reminded me of my sophomore highschool year. Kid left it in and started the lathe sending it flying and we all got to watch the shop teacher chuckle and go "great now drop and give me 25" (while the machine was off of course)

Great camera work! Curtis seems to know what he is doing! (understatement!) Great job ! those cutting tips are amazing!
