we just need a few helpers & a few years to solve all the world’s dust with open source designs

Your videos are teaching me so much. Learning how to learn and think are invaluable. Keep it up!

[@chiphill4856]

Dude! These videos are fantastic! I learned Kaizen and the Japanese manufacturing process in the 90's. It has been more pivotal in the development of my personal engineering process than the time I spent getting an engineering degree, although there's no substitute for a strong technical base. You demonstrate the principles quite well and I am really enjoying seeing you design process. ✌🏼🌊

How would you calculate the difference between the strength of force that the motor pushes the air out and the suction of your dust collection. Would it be beneficial to tie your prototype in with your dust collection hose, assuming the suction is stronger than the Air Forced out. I found it helpful to adjust the blade guard a bit closer to the blade to minimize flyaways but the force of the blade and the wind created by the blade is unpredictable b/c it changes with the size & teeth of the blade, the stock size you’re cutting b/c the teeth left exposed acts as fan blades and the density of the material the motor has to power through. I realize the blade turns into the direction of the dust collection hose but then the flyaways that escaped the suction is more that likely going to come out of the front as the blade is working against the suction in the blade hood. In other words, I’m watching this closely b/c i’m having the same problem and I’m having to change my respirator cartridges sooner than normal and they’re $25 a set. I’d prefer spending that on lumber. Oof! Sorry for the rant! I feel a little better now… 😅

[@davidmalawey]

from your comment i’m pulling a specific phrase: “flyaways that escape the suction” i had a LOT of these. after i added the blue tube, these are reduced by over 50%. huge results. if you just run your saw and feel the air around it, with your hand (and slow way down, take time and consider everything going on) you’ll notice in your situation where the main air movement is originating. then narrow down countermeasures. everything you mentioned is relevant and it’s quite a chaotic problem at the very start.

[@raymondreyes4244]

Even if you blow air all over out of the motor a better solution is to put extraction (not a regular vacuum) where the wood chips fly off the saw.

Design not finished

[@tomasharviemudrunka3168]

Just put air filter at the intake?​@@chiphill4856

[@paulvild]

So does that get plumbed to the vacuum or just redirected? I would be tempted to plumb it to the vacuum, but then I'd worry about sparks getting thrown into the wood dust!

[@schnauzerofdoom8819]

Meanwhile me at home with no degree and a 3d printer just winging it and hoping it works without measuring shit except the hole I need to put the thing in. Ten shit prototypes later ... I'll still take the 3k though.

[@davidmalawey]

for certain there’s NO NEED for degrees. at the end of the day your design is to solve your problem and my design is to pass new ingredients over to other designers, be they engineers or hobbyists like yourself! 😊

[@CheaddakerT.Snodgrass]

A million dust-collection videos on youtube and you are the first to recognize this problem.

[@troshto]

I really need some of those glasses!

[@skinlab4239]

Been solved on jobsites for pennies

[@emod539]

I have one of those coats. Is yours a 3L also?

[@davidmalawey]

no way! 😮 that is so rare. i think since i quit i never met someone who has this jacket. it’s LL. if i got it big enough to reach my wrists then its super wide too 😅

[@emod539]

@davidmalawey Japanese sizing is so different. Got it in Japan when I was in stamping engineering.

[@ShmeegleSon]

That’s sick

[@randomuser1974]

Hey just a thought. I can see what you're trying to do with these types of videos, and I really like it. However I think that they are a little hard to follow narratively.

[@1Patient]

You should have seen the way they cut wood before they had electricity and vacuum cleaners.

[@adampancechowski5965]

Where TF are you getting payed 172 dollars a hour as a engineer? Or are you getting payed in Zimbabwean dollars? Also your task brake down is calculated is done in the spirit of a good accountant. Turn on the machine, pop some smoke through the inlet, see where it comes out, 10mins... Eh, say 3h.

[@paulj4262]

It cites the source in the video, accounting rate for Toyota engineers as of 2014. A great example of this is the company I work, we charge 100/hr per person but I make $28 of that 100, the rate a company will charge per hour (for example engineering) isn’t how much they’re making

[@adampancechowski5965]

@paulj4262 that makes morse sense, but it depends, of it's a personal project, you can't value at company rate and if it's done through the company, then that's fair.

[@bl00dh4nd5]

You lost me with this one.
