I Over-Engineered this Machine, cause Manufacturers Didn't

When a German engineer tells you he's over-engineered something, you're in for a real treat!

I can't think of high enough praise. There exists no better combination of engineering, functionality, storytelling, humor, filmography, editing, ad infinitum. Free on YouTube. Amazing.

In regards to your fan blade question. Those are anti-static fan blades. A static electric arc discharge could ignite the wood dust in the air around the fan which is highly explosive. The motor is either brushless or induction type to eliminate the risk there as well. As far as the explosion factor the danger zone where wood dust is a significant risk is when the average particle size is less than 200 microns, and where as little as 10% of that contains dust less than 80 microns. So I will leave you with that info as well as my personal recommendation for you to put those contacts back in the fan blades. Hope this helps.

18:22 That sharpie bit is mindblowing! So cool! This whole project is incredible!

wow, epic build. I see why it took as long as it did! Loved the 3d printed gearbox cutaway view

This video is why YouTube exists. There is absolutely nothing on TV as entertaining and gratifying.

My family’s owned a manufacturing business for 4 generations, and I’ve personally been involved with over 100 companies myself, from product introduction, alpha and beta prototypes, all the way to DFM for mass production. I can affirmatively state that in this one video you’ve done more than many engineers may do their entire career. Very fun to watch as well!

My jaw is on the floor, I don't think I've ever seen such an impressive display of design, engineering, storytelling and editing in one package. Absolutely amazing, you've earned yourself a sub.

Feedback: This is THE most impressive build video I’ve ever seen. Humor, education, solid narration, an incredible result, seamless Ad integration, and all in 1 video. 😮

Holy shit, 1.5 hour video from Marius? Christmas came early!

As a professional video editor, it was the perfect combination of complicated and simplified. Didn't know where the time went. Brilliant.

I was initially shocked by how smoothly everything seemed to be working on the first try. However, your demonstration of the numerous failure-parts at the end was a small relief. What an incredible project! Thank you for sharing!

I love how the tolerance chart goes from "Close" to "Good" directly to "Shit" so true lmao

i just realised I just watched an 80 minute video about engineering and building a machine I never needed and will probably never need in my life. But I enjoyed it very much. I very much appreciate you didn't turn this into a 4 episode series of 20 minute videos. Instead you put in all the effort into creating an epic video about constructing an epic machine and the result is one of the best videos that exists on Youtube. I really hope that making videos and things the right way instead of optimising them for maximum profit or monetisation somehow pays off.

Beautifully over-engineered! Unbelievably good. I'm a software man and have no clue how many HOURS this took? 3000? 10000? Thank you for making such a detailed video. Inspiring!

Selten habe ich hier oder überhaupt jemanden gesehen, der derartig gut und vorausschauend entwickelt und arbeitet. Absoluter Respekt für dein handwerkliches können und deine Fähigkeit, so ein Projekt in dieser Qualität umsetzt.

24:40: It's a retrofit in the design to comply with DGUV, which says table saws must come to a stop within 10 seconds. I honestly can't find the specific requirement spelled out in 100-500 any more (it used to be, see VBG 7j § 12), but 100-500 references EN 61029-1:2000-02 and EN 61029-2-1:2000-05, either of those should have it.

I'm going to be honest, I got to the 1:22:00 mark when you asked "Was the video too long?" and I thought "I didn't think it was too long, really good and dense 30 minute video right?" and saw the time. This was an AMAZING video and really shows all of your skills from the great engineering, the wood working, the machining, etc. Truly keep doing what you're doing and inspiring me and many others!

Bravo! I have watched you grow up. From an enthusiastic young woodworker building Mathias Wandels bandsaw, through the years to ever more complex projects. And, now you have become a sincere, articulate, humorous, interesting, educational and informative teacher of engineering concepts and innovation. I think you have made a wonderful transformation of yourself into a master craftsman as well. Not just in the projects, but videography, project planning, technology utilization, and resource utilization. You have turned yourself into a one-man university for autodidacts. I highly commend you and your great parents. You are the blessed son all would want to have. May you "prosper and be in health, even as your soul prospers". Peace be upon you always. And never stop teaching and sharing.

A masterpiece. I hardly blinked and watched the whole video in one go. Amazing.
