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 
!! So, only 346 left to go!!... 
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!
When it's done it'll look like this image I found on google
Oh wow that's really cool! I'm going to start learning how to weld next month, but it's mostly as a support skill for my woodworking. Clamps specifically are insanely expensive where I live, so being able to make my own clamps from cheap flat iron bars will save me a preposterous amount of money in the long run. Your tetrahedron looks sick, way beyond the level of complexity I think I'll aim to achieve in welding lol congrats!
It is HUGELY useful with woodworking projects so far.
Plus, unlike when you glue wood stuff its instantly strong so whipping stuff together for even a jig or such can be really really fast, and super sturdy.
My next practical gambit here will be making some tools for myself, I've also been learning blacksmithing (I have an adorable little 20kg anvil and I turned a pressure cooker into a forge) but with my shoulder hurt I've been.... not blacksmithing for the time being :(
P.S. please share your design for your clams when you build them, I too could use more clams and I LOVE making shit instead of buying it if possible
