How long will it spin? (made from solid steel)

In this video, I made a solid steel top that spins for 15+ minutes! I made this massive top in a couple hours on a Saturday afternoon. I'd like to issue a trigger warning to all of the machinists out there 😂 No doubt some of you about had a conniption watching me make this lol. Channel update: Hey guys! Sooooo.... it has only been like 6 months since the last upload 😬 Who knew that going to college was going to take up so much time 😂 I'm currently on winter break and had some spare time to make this video. It ain't much but it's something! I forgot how much I love making these videos so imma try and make these videos a priority for the next semester. Got some cool stuff coming soon! Also, I got an Instagram! I will be posting more frequent project updates and other stuff over there! Follow me @happy_mad_scientist -- Thanks!
