This Project took me 2 Months

My oscillating belt sander had a severe design flow and needed to be fixed.

It’s not the side to side movement, it’s the height of the crown. The makita has more crown, over 180 degrees of crown. You only have about 15 degrees of belt on your crown, which means the effect of more tension in the middle is much reduced. Also, you want a long run before the crown. It’s how the belt flexes on approach to the crown that makes it track. I have a video on this, so does Steve mould.

Wow! So much interest in the competition! In view of the large number of participants, we will be giving away three more sets. So there will be eight lucky winners in total. Good luck to all!

Dear Marius, thank you once again for the great cooperation. We are totally impressed by your perseverance with this project and really appreciate your work. Nice to see that our tools were a good help.

Despite the challenges, this video is a great illustration of the whole prototyping process. Great idea -> first prototype -> unexpected problem -> problem solving -> next prototype (repeat several times with other unexpected problems) -> complete the functional prototype. Then, of course, there is a whole additional process of converting a hand-fitted prototype into something that can be mass produced. Great fun to watch.

I want to win a PROXXON tool, that’s it.

When version 4 functioned properly you took a breath while staring at the machine and I so know all the emotions that were in that moment! A bit of math about how long it took, a huge amount of relief that you wouldn’t need to relive some of the worst moments, and a the rest of the breath dedicated to some giddy humble pride. Thank you so much for sharing the whole process and demonstrating what resilience looks like!

[LuminousWatcher]

The end result might be considered boring - but the enjoyment you had, as well as all the lessons learned make it worth it. a no-nonsense tool in your shop is priceless.

[pastaalalamborghini]

Good example of the development process! Perseverance through failure and showing that failure, while frustrating, is how improvement and learning happens and is all part of the path to success.. this needs to be shown more!

[darrenmoore]

Marius, the genius isn't in the design, it is in the knowing that it needs to be better. The average punter out in youtube land would have looked at the first iteration and gone "Yep, close enough is good enough. It works so I'm done. You looked at it and said "Damn, I can do that better"... then did it. It really is a marvellous little piece engineering. Well done.

[B-SPOKE]

Job well done. This process of prototyping and testing is the reason why quality tools and machines are so much more expensive, but so is working with them absolutely priceless! Go on!

[windsunho]

I love the way you did your ads in this video. Completely seamless and didn't affect the flow of the video at all. I wouldn't have even been able to tell if not for the AD watermark. If only more creators could find sponsors that were as appropriate for their videos as yours were for this one. Great job on the sander. Glad you stuck it out and shared your struggles with us.

[VacFink]

Seeing problem solving in iterative prototypes is far more informative than just the resolved solution. Excellent work.

[eliezernegron]

Wow what a difference from a teenager to an adult, I remember when you started your channel until now.. congratulations 🎉🎉 going from your parents to your own shop ..👍👍👍👍

[TobiX]

1:30 looks totally fine and useable. I would have stopped here 🤣

[Blasfemurr]

I'm not an engineer, I'm not particularly patient nor am I even an above average woodworker - yet here I sit with my coffee, utterly fascinated... well done, really enjoying this process :)

[karlgabel]

Had to laugh at "I'm a naturally good designer. No need for testing." My boss told us this one time when we were building test benches for programmable logic - "I design it to work right the first time." Was his quote. I have also gotten demerits for taking too long on testing. But I have gotten bit in the rear end too many times when taking shortcuts as a new engineer. After 41 years in the business, I have learned that hubris is painful. Good for you learning that early..

I want to win a PROXXON tool, that´s it
As a mechanical engineer, I found this an educational video for anyone who wants to make mechanical engineering a career.
Marius this is one of your best videos you've ever made.
twelve out of ten thumbs up.

[ethanwaldo]

It's really great to see your steadfast persistence and attention to small details. It's also satisfying to see your joy when each part finally comes together. Truly a master at his craft.

[sylvainlopes]

Thank you for sharing your engineering thoughts and process on how you do things, it's really a blast to see something being built this complex from the ground up and showing iterations.

[KK-WNY]

It's always the hardest-to-find piece that falls on the floor. That bit made me laugh.

[PjotrStroganov]

I love to see the amount of lessons learned from ‘failed’ prototypes. Personally I don’t see them as failures because of the knowledge gained from them.

[StormBurnX]

35:47 that is brilliant!! Why have I never seen that on anything before. So simple and elegant. My only guess is that it will rattle loose over time, but I'm sure some pressure could keep that minimal, and a knob on the end of the adjustment would double as a dial indicator to show when it needed re-tightening!
