The determination of this man to machine those inside threads instead of just buying a tool for it, or even buy a whole new cyllinder, is what makes this channel remarkable.

[@DuaneMckenzie80]

New rod would of been stupid expensive let alone a new cylinder. But yes, he's a bad ass.

[@JerryBarron-qr4wy]

Well said and I agree 100%. This guy can, and does, incredible work. Love his channel.

​@@DuaneMckenzie80 I imagine he's making a decent income from KZbin - but it's much more educational/entertaining to watch him fabricating.

[@thewayidoit8895]

WHO IS THIS MAN?

[@Bigdave80]

To answer your question about the bolt vs nut to retain piston: the bolted connection is stronger for highly loaded applications. You can run different material for the bolt and have less chance of breakage than using male threads on the rod. I used to be cylinder design engineer for a major construction OEM (not this brand, but one of their competitors). Almost all our cylinders used the bolted type connection.

[@FarmCraft101]

Thanks for the info.

[@dans_Learning_Curve]

I guess a bolted trailer ball would fall into the same category.

[@TheBibliofilus]

@@FarmCraft101 When working on hydraulic cylinders you always heat the parts you are taking apart as they are always glued unless there's a mechanical locking tab, but there still might be glue! The most common glue I've seen is the GREEN Loctite ceramic glue for fixing loose bearings etc. and that stuff MUST be heated to about minimum 250C or you'll end up destroying the threads if you even can get it loose....

[@court2379]

This is a material availability issue right? The rod isn't available in the higher strength materials that screws are? I ask because at a glance I would say the tensile stress area of a male rod would be larger than one that was female.

[@dans_Learning_Curve]

@@court2379 the rod is only hardened on the outside layer. If the rod was used as a stud, it would be softer than say a grade 8 bolt.

[@davidsnyder2000]

CEE is one of the best resource for turning eyelets and cylinder rods👍Feel like I’m watching Karen and Kurtis😊

[@donmedford2563]

Davidsnyder, you are nuts. Karen is MUCH better looking than John is. lol

[@mikes78]

I was watching this an thinking "i don't want to think how much a new rod is going to cost him". Then the blank rod came out, then he mentioned the button and i was starting to get a feeling of Deja-Vu with the technique. All he needs now is a Staffy and he's sorted.

[@WatchWesWork]

It's probably wrong, but the way we used to machine chrome rods was to heat the area we wanted to cut to a very dull red with a torch then let it cool. After that you could cut it with HSS tools (dad rarely had carbide). The thinking was you're gonna lose the heat treat in that area anyway when you weld it. Same for the piston end, you're going through the hard layer anyway. You just have to be careful and not go too far because it will mess up the chrome. Seems like if you can get under the hard layer you can machine it much easier.

[@tutekohe1361]

That’s a good idea, Wes. Seems obvious once stated.

[@greylocke100]

Basically anneal it. I don't know about annealing chromed induction tempered steel, but Most of the commenters may have an idea at least.

[@leighwalker3914]

Nice job, click.

[@davidosterberg]

Wow, that was impressive. As all armchair machinists, I have seen CEE do these many times. But it is his specialty. It is something else to take this on an amateur, doing it with the equipment at hand. Probably you have seen CEE as the rest of us to build the confidence to try this on yourself. Says something about how useful KZbin is as an educational tool.

[@HappilyHomicidalHooligan]

CEE also doesn't tend to deal with rods this small... The larger diameters he regularly works on helps too...he has LOTS more room to work in/with... 😄😁😆😅😂🤣

Do you ever wonder how many folks give a collective "THERE" when you finally get a stuck thread to budge? I always chuckle when someone who is watching me work on something that is stuck, and they really want to help, but it's one of those type of things that only one person can do. They give an exclamatory "THERE" when it breaks free; and I smile and say, "Man that was a tough one, thanks I couldn't have done it without your help", then we both have a good laugh about it. Great video John thumbs up.

[@MA603lfod]

Great content and work Jon. I watch Kurtis do these things and think it is only for professionals. But then you go and figure it out. Really impressive.

[@timkirkpatrick9155]

When you don't have a wrench that goes high enough, do the math! length x weight at end... Most times people doing it to click are over doing it which makes later work harder. Bravo for clearing the sight glass. It does make life easier. Good looking job, as usual!

Kurtis at CEE will be proud. I am always fascinated by lathe-cutting of threads. How the cutter knows to start in the same place every time while the stock is spinning is magical. Great video, Jon.

There's a threading dial that the operator watches. When the line is at the correct spot, engage the halfnut that feeds the carriage. That's one part he didn't show.

I am sure Curtis would give you a big thumbs up on that, great job man.

[@engnerdan]

You can end up crushing the threads when you have the chain that far back on the gland nut. Which will make them bind and not want to move. Placing the chain further away from the threads (near the front edge) can reduce the chance of crushing the nut.

[@elanman608]

Good Job Curtis would be proud of you.

Keep up the good work I'm a fellow past farmer with a small machine shop at home including a lathe and a Bridgeport.

That's the only way that I single point thread these days because it's much less risky. If you mount your tool on center but upside down and thread on the side closest to you the moment is shorter at the tool tip so you get less spring from your tool post.
