Mild Steel VS Hardened Steel - 100 ton crush test 

Well said. 30k lbs bouncing around and the only difference between that and other metals is come carbon and some heat treating.

Hi c. Just wait untill you experience the new metals using graphine and nano particles. It amaze your mind , body and soul. You should look into graphine it's on the periodical chart.

@@go5582 Is any of this commercially available yet? I'm putting together an antitheft product.

Gotta have some entertainment mixed in with the work hehe

what is a mm?

@@simcoespring A pretty good piece of candy ha ha

Cool info. Now I have to look at all my lock nuts.

heck ya! You have to have some fun mixed in with the work.

yes and that is why you need to know about steel types. hard vs soft, stuff that squishes vs hardened steel. which is why you NEVER put hardened steel up against hardened steel.... Probably a hardened punch against a stud which is also a grade 5/8 hardened piece of steel. We always use mild steel or cast to press out parts that will squish or deform when we use it in the press. I use a ton of aluminum to press bushings in because of this very reason.

I wish I could do tests like that. I'm always worried about critical failure and shrapnel.

it was fun to make.

Interesting idea. I'll have to think about that one.

We have a leaf spring supplier. Spring steel is 5160, you will have to look up the chemical materials online.

@@simcoespring 5160 is one of many spring steels.

keep an eye on the leaf springs. Watch for breakage. the 1999-2007 F350 pickup trucks are notorious for breaking leaves now because of their age. Keep an eye out for a broken leaf in the spring pack. If you break a leaf now, they are probably all close to breaking and you should just replace the whole stack. we usually look at age/mileage. If a spring has over 200,000km or 160,000 miles and is over 10 years old then you did pretty good with the leaf springs and if they start breaking you should probably replace the whole stack. However if you only plan on keeping it for a short while, or can't afford a whole new spring, you can just get a single leaf replaced and that should buy you some time. We also come across leaf springs that are worn out, sagged out, bagged out, unsprung, whatever way you want to call it. Sometimes if they just can't carry what they used to carry, then you can either put new leaf springs in, or add an extra leaf to the spring stack and replace the plastic pads and other hardware pieces and buy some more life out of them. So ya, lots of options depending on the age/budget/mileage and how long you plan to keep the vehicle will determine what you want to do with the suspension. **final note, if you have high mileage on an old vehicle and you need guaranteed use without a breakdown, sometimes a fresh set of springs and shocks will breathe new leaf into an older vehicle. rust buildup between the leaves and old shocks can really ruin a suspension even if nothing is broken.

Thank you for the great info! This truck has 115,000 miles. My f 250 has 175,000 miles. How much should I expect to pay to replace the springs? I have no clue who does that around my area, wish you were closer 👍🏼

yes, I still love it even after 36 years.

sounds like a cab and chassis truck. Sometimes you can just get a main leaf and just replace it.

heat affected zones from welding are often the failure point further down the track, its also why cracks form just outside of the welded area. So that is why a welder / designer must choose type and locations of welds carefully to minimise such risk. it is not a good idea to weld across a draw bar on a trailer for instance. Large elements that are welded are usually preheated, then cooled slowly after welding.

I have an idea about that same process for leaf spring eyes when we roll them. One quenched in water, oil, annealed in sand. One annealed in the forge. One normal one and one from the factory. However I need to build a safety cage around the press. So that wont happen for a while.

I wonk on maintaining dump trucks and on the U channel frames it says “Do not heat or weld, hardened and heat treated”

spring pins, king pins, they are case hardened and crazy hard to cut with a sawzall. angle grinders go through anything.

It was pretty cool. I knew the mild steel would go squish, but still impressed with the resaults

yes, I have not seen a carbon fiber leaf spring for quite a while. They where quite popular on the Pontiac Grand AM and Grand Prix back in the day.

@@simcoespring corvette also

I don't know why I didn't do it sooner. A lot of fun

@@simcoespring Really ?!? Then again, youre probably too busy working to be bothered. Seriously though, Id like to see some other types of metal get crushed, like some Aluminum etc to see how it forms under pressure, does it crack or flatten like a mud pie ? And does the temperature Rise when being under pressure, like an ice cube and how it melts when under pressure, All that good stuff ... For Science ! Cheers mate.

that is a very loaded question. depends where you are located, what kind of work you do, do you own the business. how many years experience. if you want to discuss this in length, message me on Instagram @simcoe_spring

Dang I don’t have an instagram but it’s ok I was just curious. I’m in NJ got 5 years experience and we only do springs which include air ride, lead spring, bushings, king pins, chassi work, repairing and replacing leaf springs etc pretty much anything that has to do with springs on every type of truck from muscle cars to macs to ambulances.

It’s just suchhhh a hard and dirty job I feel like the pay should be so much more and no one else in my area does this kind of work so I was always curious to know how much other guys that do this same work get paid and btw I work for someone. They start us at 17 an hour rn I’m making 20 which is impossible to live off of in the east cost but if you don’t feel comfortable talking about pay on here that’s totally fine I was just curious and unfortunately I don’t have an instagram so no biggie but anyways I like your videos it’s cool to see how other guys do this type of work, by us we don’t have a dig out so we gotta crouch down or lay down to work after jacking up the trucks

Fun

Hay

Yah exactly. Big press go squishy. Just having sine fun playing with different materials. I actually didn't know that our deep nuts where the same material as a regular hex nut. So I learned a few things.

Yes, the burgers and fries there are great. Ice cream too. If only i had more room for tools and equipment. I did buy a cart for the carbide tip saw tho a few weeks ago and it is much better.
