Machining & Welding - Rebuilding a Hydraulic Cylinder Rod, Manual Only Machine Shop 

Thank you. There are many ways to do the same job. They are all the right way if it gets to the same end result, a happy customer.

It's the only good use I've found for snow. Surprisingly this weld wasn't bad at all. I wasn't expecting that. Thanks for watching

That was definitely I.H.C.P. shafting.

@@seanmullen2287 It breaks like that when you try to straighten it sometimes. too.

Yes it does.

@@seanmullen2287 What is I.H.C.P. shafting ? (C.P. = Chrome & Polish ?) Thanks

@@petermoale2116 it means Induction hardened chromed and polished.

Far from a master. I'm still learning something new everyday. Thanks for watching.

Is that like a Metre Rule, except used for horses..?

I call my 6" rule my multi tool/ Orange peeler coffee stirrer 😃😄😅

I had heard that on some was for the added pressure to start the push, but makes sense for starting seals.

Thanks Aaron. I could only wish there was work like Kurtis has here. He cure has fun jobs come in.

Like Kurtis but without all the profanity. 😆

@@chrisstephens6673 it's hard sometimes. I have to edit it out. Lol

@@chrisstephens6673 Ha ha ha, us Aussies like to swear (cuss). I think it's in DNA 🤣

@@AaronEngineering I guess that is something else you learnt from us Brits 🤣🤣 It comes with the English language even though some say you have your own now.🤨😂😂

I never get that information. Sometimes I get curious, but mostly just care about the pay. Lol

We are always curious too! We rarely get the application information about hydraulic repair jobs. Bummer!

Totally agree. And we now only use 1045 chrome, unless the customer specifies.

The induction hardened stuff isn't bad, but it can be. The big monarch sold yesterday at auction. Just waiting for buyer to.make arrangements. No idea who it is yet, hoping it's another RU-vid machinist. I would love to see it's future.

Hi, I am unsure of the grade. Guessing 1045 or 1026. The customer supplies the material, whish is far less headache for me.

I've found the chrome isn't much trouble if you don't plunge in, but cut normally with at least .100 deep. Seams to peal it as it goes. Those lodge cast product are insane. I have cut a few, don't remember what I did. Just remembered it was harder than induction hardened bar.

I used to make class 30 gray iron typical in these applications. Likely you hit a chill area in the thinner sections as Lodge doesn’t need to pay attention to making iron thats machineable. They probably skip the additional silicon necessary.

It's all cut with carbide. The rods are cut, induction hardened, ground to size, electroplated, machined and lastly the eye is friction welded. We don't use any soft jaws, mostly collet chucks

Well I’m old and most machine shops used tool steel for routine gray iron castings. When tool steel hits a free carbide or an excessively chilled area the tool will break. As for Lodge stuff, I’d give it a file test just so you know what you are dealing with.

In my machine tool days we used special grade un coated inserts for the hard cast iron then In my tool & die days i used that trick to mill 58-60 RC Cpm-m4 And D2 we used CBM on uninterrupted lathe work

I have been upgrading as I can afford it. Check out my latest content.

Hi Dave. The hydraulic jobs come from a hydraulics shop who supplies the materials. Welded with ER70S-6 .045 wire.

I have watched Kurtis. He does a good job.

the last several months, I have been going steady on just making parts. Cleaning got pushed off, only clean enough to keep going. Now, I spend 30 minutes at the end of every day just tidying up. It has helped considerably. I try to plan some cleanup into each job, then take care of it at the end of the day, so 4-5 jobs are all done at once.

I will do a tooling video coming up at some point. Thanks for watching

@@TopperMachineLLC ok thanks

Never thought to use it. Might try it sometime, but I prefer the way I do it.

Maybe because he doesn't want to form left-hand threads?

@@TopperMachineLLC I also have done a ton of thread chasing & hyd repairs. My Lodge doesn't have that reverse feature so I know how you probably have the muscle memory set for the way you are used to working. We all have our habits that work for us & that we have confidence in. I also had a similar looking rod repair on a box truck lift gate, so I know how both cylinders need to be the same length. Great job.

Monarchs are just that smooth. Others are not as well build and make more noise than the actual cutting.

Gears are not straight cut gears they are mainly helical cut gears in the gear box, that is why they are so quiet.

No, I quit watching him a long time ago.

@@TopperMachineLLC not

I have never had a need to.use ceramic yet. As long as the first cut is deep enough, it cuts fine.

I bet it was exciting.

I have broken cylinders like that on my excavator thumb cylinder.when I am packing debris into a high side truck it just takes a little mistake for the cylinder to contact the top of the box and snap.

I really don't know. I'm not in the business of scrapping, just making parts. Usually I give the scrap away. It's honestly a waste of time for me to deal with it. The last time I hauled some in, it wasn't worth my time and fuel. I had 6 ton on the truck.

@@TopperMachineLLC Just seeing the chips made me ask. Thanks

5 cents a pound x 2000= $ 100 a ton x his 6 ton = $ 600. Nice ice cream money to me. Plus add in alum, brass, cast iron and misc. Not bad if your close enough to the scrap yard on a slow day.Thats over 30 cases of beer.

@@edwardkawecki8101 if he runs his shop right that 600 is way less than he could make doing machine work. I do demolition and have heavy equipment that makes it trivial to load and transport 6 tons of scrap. Many jobs I would rather give it away than have to take it in to recycle but I do it because it's part of the job. It takes time to accumulate, load, transport to scrap yard, wait in line, wait to dump, wait to dump different grades of scrap, wait in line to get out, wait to get paid and go back to the shop. I am only half an hour away and it is still a three hour ordeal. When the price of scrap was 300 a ton it was a different story. He probably doesn't want to waste shop space accumulating scrap when someone else will take it for free or pay a little something.

On a dirt floor and using a claw hammer.

@@richardcobb2852 ... they have claw hammers there?

Interesting. They must be paying for ads that target videos like mine. Well, don't send them the work, sent it to me.

I was wondering that too. It was definitely bent slightly. I wonder what else was broken or twisted on the machine it was on.

Yeah it appears they got something between the ram and pried it sideways. Certainly not an overload break like you normally see.

Unfortunately, I don't see much of that Metric craziness.

I know.the difference, autocorrect does not.

@@TopperMachineLLC OK!

You obviously skipped around in the video and missed that part.

I didn't see it either on the first threading pass.
