[@georgemccune2923]

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.

Yeah I've wanted a spindle sander with these features for years, but looking at his design? That's a $50,000 tool.

Because most of the fabrication was automated, shouldn't have been more than low 4 digit hours. Designing probably a few dozen to low hundred hours. Fabrication another several dozen hours. Video production 50-200 hours. So ball park estimate 200-500 hours, assuming he didn't need to research to learn different stuff and everything goes smoothly. Add a few hundred more hours for trial and error and redesigning and remaking stuff.

Maybe SCM or Felder would be interested who knows. Jessem likes to make durable tools and has a group of engineers.

[@philohan95]

Marius, your keen eye for ease of use while incorporating advanced features is astonishing. Your editing skills are also very good and makes the viewer not lose interest with your perfectly balanced level of humour of boosting viewer enjoyment without being silly. You discussing your decisions and obstacles you hit and how you overcome them really shows your skill. You're my favourite DIY'er.

[@JPToto]

Somewhere there are a bunch of product managers at tool companies smacking their heads and wondering how their teams didn't come up with _any_ of these ideas.

[@sciencegey]

Except they already have; an oscillating belt sander isn't a new invention.

[@Flako-dd]

Agreed, most companies only care about "value" engineering. Not "real value" engineering.

Festool would sell it for 1600 give or take a thousand.

[@SpitfireMkIIFan]

This thing is vastly overengineered, in other words: Expensive. No company spends more than the actual amount of work needed, and Marius likes to design and build such things so its both a combination of his hobby and and actually creating helpful tools for him. But this would not be suitable for mass production.

I am currently unemployed, and I've watched many DIY videos. Since I often watch 2x speed, I have consumed a significant number of KZbin videos so far. THIS IS one of THE BEST videos I have EVER WATCHED on KZbin. You show incredible technical understanding, material science, craftsmanship, handling machines, patience, and ambition! Thank you very much for inspiring the world and me personally.

[@kurtlee3198]

why such a rush to watch vids if your unemployed? you charged on amphetamines or something? 4 windows open watching 4 different videos on 2 x speed about to break out of the matrix?

[@Bob_H]

I admit that I broke this down into 3 nights of viewing. BUT I have also watched it, and many other of MH video's, over and over. I truly enjoy them. They make me get up and make things.

[@SeraphimKnight]

Don't get me wrong, designing and building your own oscillating sander is extremely impressive... but I'm blown away by that sharpie trick! Holy cow, this is life-changing.

[@repapeti98]

My jaw was on the floor the entire time. My projects range from filing down my bike's old V brake mounts because I run disc beakes and painting them with nail polish to using a jigsaw to cut into the pantry door frame because our fridge doesn't fit. Meanwhile you add a few microns thick layer of sharpie to a bearing so it's a press-fit. Unbelievable craftsmanship.

[@umchoyka]

Blown away at your machining skills and ability to communicate complex ideas in a digestible way! I really appreciate having this as one long video with all the explanations, this is fantastic to see.

[@ColeHomestead]

I mentor a local high school robotics team and shared this video with the kids so they get some insight into how the "design for function" concept I've been trying to explain to them works in practical application. Thank you for explaining the steps and thought process as you worked through the little bugs and unexpected "features". Great job!

[@bwillan]

Between Marius and Jer Schmidt, those are two engineer/fabricators that I could watch their project videos and not get bored regardless of their length. Looking forward to phase 2 of this project.

[@cooperised]

Add Phil Vandelay to your list! And perhaps Cosmas Bauer. And Matthias Wandel of course.

[@marknaddzze]

Marius, Jer Schmidt, Phil Vandelay, Cosmas Bauer. These four are the best!

[@johnjarvis9519]

The quality of your videos just keeps increasing with every big project Marius, thanks for all the work you put in to share with us, it's truly a gift

[@MattSitton]

Honestly this build is incredible combining modern computer controlled machining 3d printing and older techniques. Wood working, metal working and plastic. Insane, Love it!

[@timthomas9105]

It's very rare for someone to combine multiple disciplines. In this one project I saw computing, Electrical, 3D printing, mechanical engineering, CAD design and metal work. I was a member of the Computer and Electronics Book Clubs, Life Member of Handyman Club of America and my 30 year JOB was in Electronics and Computer Science. What you've done here is remarkable and I am just a little bit envious. Haven't done much metal work, no CNC. I have memorized schematics, designed super wells for irrigation, access control, consumer electronics and 8 years in the US Navy as a Nuc Weps Comm and Satcom Electronics Technician. A proud day for me was passing a 6 hour board exam from the ETA for Master Certified Electronics Technician. Those days are over and in my past. So God made people like you to challenge my mind and teach me something new. God Bless you. Tim

[@LaMalediction666]

I thought that the video was too long, the first time I saw the thumbnail. But when I watch it, time flew very quickly. It was very great!

[@Andy-sj2hl]

My feedback on the video is that I started watching this on impulse and it was an hour and 20 minutes later before I noticed how long it was. Very few makers make content this long form and this entertaining to watch.

[@KeithOlson]

I just want to let you know how much we appreciate you including when things went wrong. Every single screwup you show us increases both our trust in you--for your willingness to be honest--and the likelihood that we might try something like it ourselves because "If a expert like Marius can get things wrong again and again and again and again yet still keep going, maybe I can, too!" Bravo, good sir!

[@paulleos162]

Gies to show that there's always ways to improve an old engineering design. Great job. !!

[@dalejones4186]

This is the exact reason I watch your channel. You are an amazing engineer and maker. Thank you so much for sharing.

[@Heroo01]

I did NOT expect to watch this whole video when I clicked on it. I was fully intending to skim through it out of curiosity, but I was hooked pretty much instantly once the work started. Very well done, and fantastically paced editing.

[@nathanb62]

It feels like you are absolutely blasting through all the steps but it's still 1.5hrs long. Thank you for not making it shorter. I love seeing all the steps and work that goes into this. Great project, great production quality, great personality and narrating. Up there with Stuff Made Here and Proper Printing.

I think the length and level of detail of the video were just right Marius I really enjoyed it, thank you.

Just a sanding machine but awesomely over engineered, head spinning complicated build. You are a real genius. Rock solid video without any epilepsy inducing memes or irritating background music. That's what I called a legitimate channel which feed the viewers with valuable contents. Thankyou Marius.
