The whole RC truck and heavy equipment scene is pretty amazing!

Probably unfair take of me, but I don't the video shows the actual process. I don't believe you can get the precision needed by doing it like this video shows. I think something else is happening off camera.

There are a series of TikTok videos that show the actual construction where you see each piece being fabricated.

Yep, it is unfair.

There is nothing that is impossible in the building process, only it takes (took) ages.

The linked video is a "final" version, there are smaller videos with more details, this one is about making the tracks, posted on hackaday:

of course there are also pre-made metal parts (possibly also hand made, but needing a small lathe), but the PVC tracing, cutting and gluing looks entirely real.

I don't say it is impossible, not at all. But I question if it is completely made by hand like shown in the video, or if there perhaps are CNC machines or laser cutters to help, but not shown. For example, the holes line up so well even though they are hand drilled. I wonder how he can achieve the needed precision with just eye measure.

Rudimentary, yet clever mechanical engineering.

While watching I was comparing the entire build to 3d printing. More specifically the process knowledge gained doing this in CAD and then 3D print vs handy making parts from PVC.

VangHa's channel is so cool. They make a ton of really well crafted stuff with extremely simple, DIY tools.
