Caution! CT Body Casting Has RAZOR Edges

[CT_AZ_4x4]

I sliced my finger as if with a razor blade while inspecting the air tank and very lightly/casually running my finger along an edge/ridge of the aluminum casting.

Ouch!

Lesson learned!

The truck’s unicast body has these ALL over the friggin’ place. Be more careful than I was!

Yes, I too had my share of 'Cybercut' when I worked on my Cybertruck. ?

Wow! That's the first time someone has cut themselves working on a car!

Seriously, are you new to working on cars? I've cut myself probably 50 times working on ICE cars/motorcycles but I would never think of dedicating a thread to it.

Because there are sharp edges on all vehicles, once you start diving in.

I’ve wrenched on dozens of different cars including entire engine and transmission rebuilds and replacements. This is the first time that my vehicle has sliced me like a razor.

I’m being honest that I was not expecting that the body, in this instance of course a die-cast one, would slice literally just like a razor. It was entirely unexpected.

My favorite car was a 1969 Ford Falcon that I rebuilt the engine and tranny on. It was a great little car. The largest that I’ve owned and worked on was a 1979 Ford Ranger with 2-20 gallon gas tanks and a 460 cubic inch v-8. It would get 10 miles a gallon practically at any speed and practically any trailer load.

But no prior vehicle body that I’ve owned sliced me just from touching it. So thanks for amplifying my warning to other forum members. That’s very kind of you.

So that’s where my “thumping” sound is coming from! I occasionally hear and feel a loud thump coming from that area.

Is that why you’re inspecting yours?

I have heard some weird noises (rarely) like a sudden release of air pressure that seems unrelated to the air lift, and that was one reason I took the floor bed cover off. I also was measuring to see if there was space to cut the floor bed to allow for mounting the 35-inch spare tire vertically, and my initial engineering thoughts after taking a few measurements are that it would be a bad idea to do so.
And I continue to try and recreate and locate that bizarre air whoosh rushing sound.

I wear tight fitting nitrile coated gloves when servicing the vehicle, allows for dexterity and sensory, learned the hard way lol!

Yeah cars have sharp edges, but not like that. As most cars were/are assembled by persons - even the parts are relative free from sharp edges. Sharps parts also cause damage to things around it like other parts on the shelves, scraping material off the shelves and packaging.

In Aerospace there is a term call FOD. Foreign Object Debris. Which can be completely catastrophic when it occurs in internal plumbing, like:
Brake lines
Fuel Lines
Cooling lines
Hydraulic lines

Entire vehicles, entire production lines, and WIP [Work in Progress] has to be disassembled to find the cause. And typically the causes are detritus collected after the part is made and during parting handling.

Looking at his photo where he cut his finger, there is a 'assembly' with lines and hoses. So consider what happens when you are 'servicing' that assembly, detach some components and drag them over / out-of-the-way and they are cut/damaged by the 'innocent' process?

I would be piss & vinegar if I pulled a brake line from a caliper and the fender sheet metal was sharp enough to slash the line.

Most ICE cars don't have 'razor' sharp edges. They should be designed to be 'serviceable'

My assumption is that he dragged his hand across the novel 'cast' frame as anyone would - and got bit.

I worked as a machinist for many years - any guy who made a part and left burrs - was a looser. You deburred the parts even though the drawing did not expressly call for it.

I am appreciative that he especially called attention to the cast frame being sharp - so if I bury my arm down there - I want to pull back all my fingers...

The rear subframe is a single-piece casting AFAIK, so I'm not sure why there are seams. Other photos of this piece (like here) show much more subtle lines.

I'm guessing that the casting die is not one single machined piece, so that the casting ends up having a small seam at the junctions. Those junctions probably degrade over the lifespan of the die, and thus and leave behind a little extra material.

Thank you for your insights.

I worked on fixed wing fighter-attack aircraft in the Marine Corps and know a thing or two about FOD. Getting sliced by the cast body was the last thing I expected. And those ridges of razors could be dangerous to air supply lines or wiring harnesses if dragged or compressed over/on top of one as you point out.

Thanks again.

Sigh! It's easy to draw blood when doing mechanical work on cars, trucks and motorcycles. Ask any mechanic how many times they have sliced themselves open and drawn blood. The goal is to minimize those incidents by being aware of where sharp edges are and trying to not contact them with bare skin.

Many pros even wear cut-resistant mechanics gloves. Let's not pretend this only happens on the Cybertruck or that cuts can't be avoided by watching what you're doing. Some people like to blame everyone but themselves when they don't pay attention to the task at hand. Man up and take responsibility!

Ouch. Hope all you Cybertruck inspectors out there have up to date Tdap shots.
that really sucks @CT_AZ_4x4

You’re accusing the wrong guy of this. I can assure you. I see where you’re coming from but I know the OP and your interpretation of what he is saying and what lead to this happening is dead wrong. If anything he’s a Tesla apologist, not a blamer.
In my opinion he’s not blaming anything, just issuing a public service warning so other people can do exactly as you’re suggesting, be cautious.
And as far as manning up and taking responsibility, I’m pretty sure he could teach a seminar on the subject. Honestly.

This is the second forum discussing this, could we see another recall coming? Safety first!!
