> Motor: It has to be powered by an electric motor, because we no longer live in 1940. Well, that's a bummer.

That reminded me of the rocket nozzles we designed in my supersonic fluid dynamics course. It's a shame my kids have already outgrown the go-kart stage.

OSB wood?

OSB is not very nice either. Plywood is definitely the choice here. I think MDF will easily last until his kids don't fit in it though. I don't think he's going to use it in the rain.

Advantech OSB will outlast conventional plywood by a mile in the rain. I exposed it, flat (the worst way possible) as subfloor, to rains for 1+ year while building my house with only maybe 1mm of fiber degrading on the surface a few places. Many modern OSBs use hydrophobic glues impermeable to water.

The two aren't really mutually exclusive... I'm going to say, as a child of the '70s, that with proper parental supervision children can survive their parent's "alarming lack of concern for the well-being of children".

As another child of the 70s, I can tell you that even without proper parental supervision, children can also survive dangerous activities and construction projects that would invoke a visit from Child Protective Services these days.

The native tongue of the writer appears to be Spanish. They likely either live in a hispanic country or in a hispanic neighborhood of the US, where such overbearing Karen snitches do not exist.

Fun for the dad, but odds are good the original version would have been even more fun for the kid, and longer lasting. If you've never seen what a young kid can do with a suitably sized Kettcar (kettlecar) or Berg pedal go kart, you have missed out on some amazing vehicle dynamics. The designers got the weight distribution and steering dynamics exactly right. The things are a blast.

This is similar concept to taking your kids to a fancy resort to swim in the pool where they would be just as happy at the local Holiday Inn in your town.

Marine ply would be my choice

This is amazing!

I have a bud who uses a custom built electric go-kart for filming stunt scenes — specifically those low camera moves of one car passing another.

He had to build his own controllers to allow smooth acceleration as visible jerks ruin the take

His tops out at 100+ mph but I thing they usually film at 70-80mph.

But yeah — those things are death traps

Maybe but it's basically made of splinters. Not something you want in a thing you have to touch!

Nice project, but am I the only one who thinks it's a bit cynical to first advertise it as a "death trap" and then show kids riding it? Which means you either admit that the title is complete and utter clickbait, or you demonstrate an alarming lack of concern for the well-being of children.

You’re not supposed to take that use of that expression literally, but if someone gets hurt for any reason, the lawyers will.
