Making a New Cylinder Piston | Satisfying Machining

This is one very satisfying machining job! Today we are making new hydraulic cylinder piston for the Apron Lift cylinder off a Caterpillar 651 Wheel Tractor Scraper. This shows the satisfying step by step process of making the new hydraulic cylinder pistons. We are starting with a solid piece of 245mm diameter 1045 high tensile steel and begin by machining and roughing down the material, we then drill and bore out the centre before boring a 7° degree taper to suit the cylinder rod. With the machining complete on the ID of the piston we then complete the OD of the piston including machining the pressure seal and wear band grooves. Another job done, thanks for watching!
In this video we are using our Hafco TM-26120G Centre Lathe.

My favourite bit was all of it

[@SeanBZA]

Lovely to see the dual purpose gauging block for the taper thread, that also serves as drive shaft, proving the taper is perfect by not having any slip at all. Great work there, and also on getting all those measurements spot on. I would guess the piston that is recoverable would be good to machine up as a temporary "get you out of a bind" unit, so the mine owner can have it on the shelf to put in while waiting for the fix, with him knowing that this one will fail after a while, and not worry too much about the worn cylinder and rod, as those will all have to be done together, but at least he is not a machine down for a week or two, just 4 hours to replace a cylinder with a more or less working one while Kurtis does his magic and makes the old and busted shiny and new again.

When I presented him his bill at completion in the office, in front of his clients in waiting area, he decides with his 'obvious education' that I did Not take as long with the job as he thought I quoted for, so he wanted a 'discount' ? The 'Plumber', at this stage was all hot and sweaty from working out in the Sun for a number of hours, then asked the 'Dentist' with the 'obvious education', in a loud ,not threatening, voice if he gave discounts to his 'clients' if he got the job over quicker than expected ? The 'clients' in the waiting room were looking expectantly at the 'Dentist' with the 'obvious education' for his reply, he proceeded to almost break the receptionist's hand getting the cheque book off her to sign it and tell her to fill out the details, as he left the receptionist asked him if it was for the amount on the invoice, he grunted 'yes' and left !

I'm also a fan of IC Weld, and his narration is top-notch, like yours (cool that he sent you that cap!). It's midnight here in California, US, and since I can't sleep, seeing your new video appear, posted a minute ago, my time, brought a smile to my face. Thanks also for the great camera work. The varied angles, slow-mo & other speed variations all add to the production quality. Your dog and the bloopers all add a light touch, and the humor is much appreciated, these are not great days here in the US. I ended up in a technology career, but I still remember taking shop classes in high school, metal shop, wood shop, print shop & electronics. Building simple things, soldering, etc. was really fun, and I regret that I was not able to do more of that professionally. So, I hope your business thrives, and you & your wife have a long dual career, as video producers and machinists. You seem to enjoy your work, so I hope that continues, too. I've had jobs I enjoyed, and others I could not wait to leave. Thanks again for sharing your world.

My _favorite_ part of the machinist videos is the close-up of the dial indicator, _after_ the part is running true. It is _amazing_ to see that needle rock steady. The dial states that each line indicates 1/100th of a mm. That needle seems not to move at all, but if it does it is within ± 1000th of an mm. I smile and feel such pleasure at seeing how any competent machinist can do that. Humans are stunningly good at such precision.

One of my pet peeves too! Years ago, I started a new job as an Engineer and in their "Model Shop" (i.e. prototype/fixtures) they had a tiny little lathe. Covered in swarf. Later I need to make a part and took the time to thoroughly clean the machine, then cleaned it again when I was done. Mentioned it to the Chief Engineer one day. After that his other guys kept it (and the Bridgeport mill) clean.

Manufacturing tapers can be precision engineering as even a slight mismatch on the initial slide setting can be disastrous when assembling the parts. We manufactured a 21 speed gearbox used in the manufacturing of steel rope, fascinating to watch how it is all wound together. This gearbox had the input gears on tapered shafts which were also keyed and locked into position with a locking nut. Turning a taper in the gear and on the shaft was good engineering practice as we did not make too many of these gearboxes. Thanks for posting.

Sometimes when reassembling a cylinder the wear bands were a tad undersize (or the groove in the piston was slightly deeper) so I'd go rummaging through all the new old stock parts we had kept in the attic to find one which would take up the slack to eliminate the sag in a fully extended assembly. Handy to never chuck away any unused components. 🤨

hey mate thanks for taking time to watch and comment, always good to know what our viewers are enjoying or learning from the vids 👍

[@adamjacobs8606]

Beautiful parts as always

[@marklowe330]

The large MAZAK lathes I use to program would have loved this part. I actually enjoy manual machining more than programming. That button tool looks slightly modified. Enjoyed watching as always. Keep up the good work. Faithful viewer.

[@jestempies]

It would be great when you tell us the dimensions of stock metal if you could also give us an approximate weight. I don't have experience with large pieces of metal, and the weight would make it easier to imagine what's being done in the later stages. Great stuff, as always, love watching you while I work :)

[@CuttingEdgeEngineering]

hey mate thanks for the suggestion will definitely keep that in mind for future videos!

[@davidsellars646]

Take the dimensions and compute the number of cubic inches. Multiply by ,2836 to get the weight in pounds. You will have to do the math to figure the conversion in metric.

[@keithammleter3824]

@@davidsellars646 In metric, it's even easier. Steel is 7850 kg per cubic metre, i.e. 7.85 gramme per cc. For a cylindrical shape, take the length in cm, multiply that by the diameter in cm, and multiply that by 0.01937 (0,01937 is pi squared /4 X density of steel i.e., 3.1416^2 / 4 X 0.00785.) For most purposes, you can just multiply length x diameter x 0.02. For aluminum use 0.00344 instead of 0.02. Actually, CAD systems give you the mass automatically as can many digital readout panels with a calculator function.

Nothing extraordinary for me this week, Did some epic manual folding on the brake press, a few errors that i thought (and finangled) my way out of resulting in some lovely equidistant angles and conformed fabrication and a few difficult ones that i was just happy to achieve (with lots of extra steps).

[@stihl0903]

Top class job as always.

[@MrAsayaga]

What a great way to start the weekend. Thanks a lot CEE!!

[@philbert006]

Man, that seems like quite a lot of work, especially for one man. I would bet you can do it in a single day. You surely have a whole mess of tricks and tools you've engineered to increase efficiency dramatically. It's impressive and satisfying to watch you work. How long did this entire job take, start to finish?

[@davidschierholz4178]

12 hour days- but a lot of that is watching (or listening) for something to go wrong on 10 or 15 minute cuts.

[@kempy666999]

Just had an idea while watching the 2 banana drilling operation (probably crap idea that won't work🤣). If the spindle speed of the lathe and the camera frame rate were matched just right you could have the chuck appear stationary whilst the drill is diving into the material with swarf spewing out from it. (Insert comments re this is a bad idea that won't work here). Now onto the rest of the vid 👍

[@CuttingEdgeEngineering]

Karen likes this idea doesn't know how to work it out 😂🤦‍♀️

[@kempy666999]

@@CuttingEdgeEngineering Quick back of the envelope calculation for 30fps: These numbers divided by spindle speed must result in a whole number: 3 jaw chuck - 5400 4 jaw chuck - 7200 (Probably wrong, but seems to make sense to me at the time 🤔)

[@OhHeyTrevorFlowers]

If the video is 30 FPS then a RPM of 300 would do the trick. Any whole number multiple of the frame rate works, I think.

[@kempy666999]

@@OhHeyTrevorFlowers Agreed. My logic was to consider the number of chuck jaws as well - as long as the camera is "stopping" the action every 1/3 or 1/4 rotation (3 vs 4 jaw) that should work. A scan of some vids revealed that the "big lathe" has speeds of 540 and 720 rpm available. Could be worth a try.

[@pennyoflaherty1345]

Thanks great job there!

[@Lammero]

The making of the rounded corner was fascinating 🤤

[@assassinlexx1993]

Stabing a 2 banana drill. Your lathe got power. This is another great series of videos. Thats never too big. Thats whats the white lub for. 😏 Great filming Karen.

[@CuttingEdgeEngineering]

haha thanks for watching to the end mate! Yeah this is definitely my favourite lathe, hoping to have it's big brother one day 💪
