Decided to make a sierpinski's tetrahedron as a first REAL project! I built a shitty angleiron workbench (with an old door ziptied onto it as the tabletop) before but I'm actually trying this time so it's different

170 welds completed so far crab-party !! So, only 346 left to go!!... doggirl-tears

This was a really good idea until I remembered how complex fractals are, like GIRL, DUH, fuck was I thinking hahaha

Its REALLY scuffed though, I'm talkin like using my stick welder to melt a half inch off the end off of the pieces I had precut to make it shorter so it will fit in the actual dimensions needed, I've been holding the smallest (~2") pieces with a wrench and holding it in place freehand. It's been a lot of fun so far, and I'm definitely improving as I go, I weld my welding stick to my stock way less often now, and achieve arc much more reliably too, which is cool to see my own progress within the project!

I hurt my shoulder a bit ago so I haven't been able to do much lately, but welding is pretty low impact in that I mostly just sit on a folding chair in my driveway next to my shitty workbench lol

Have some more views!

Looks amazing and welding seems like such a useful skill to learn. Maybe I should look into classes near me or something.

if classes are hard to find or expensive I say just go buy a cheapo welder from harbor freight, it works enough haha

I've been telling people its basically like metal hot glue with a couple extra steps

Awesome! How heavy is this thing, it looks big?

Did you need to calculate the bond lengths inside of it, and measure/use tetrahedron angels? Or did you eyeball it?
