I do the injection molding. The texture on the inside of the blower housing looks like a "keeper" feature to keep the mold on the B-side of the mold. Sometimes if you have a really smooth curvy part surface on a mold, you can have a part "self-eject" when the mold opens which can be not ideal. By adding texture you can increase friction in the mold and 'keep" the part on the mold.

I have the similar willfuckye 18v blower. It spends its days turning my freshly lit fires into a pile of hot coals in record time. It also does a great job at distributing the dust off my shop floor back into the air to properly re-distribute evenly after a good sweep.
@@leftyeh6495 Fires? I kinda do the same thing but I've got an old $10 walmart double-acting inflator (you know, the manual pumps for mattresses and junk) with a recycled steel tube from an old assemble-it-maybe shelf unit duct-taped to the end of the hose. Battery only goes dead when the fire's flat and the beer's gone.
It's probably soft to keep it from destroying itself with debris. Only works on the lower setting in suction mode to avoid it from slapping a chunk of metal or something so hard it cracks the impeller. A machine with a sense of self preservation. "It's life, Jim. But not as we know it" -spock

I’m a forklift mechanic and use that blower for blowing out radiators, engine comportments, and air filters etc. Works surprisingly well for a battery powered unit. But for stubborn jobs you still need compressed air to do it wright. The trigger is definitely the weak point. I’m on my second one as the first ones trigger started loosing contact points threw its travel after 2-3 years of use. Keep up the intelligent comedy. Love it
Owned this blower for years...great bench top tool. Thanks for pointing out how the speed controller works. Mines been stuck on 'one' for the longest time. Going to dig into her and remove the limiter.
@Bryan Slankster Didn't get a good look at the mechanics but it looks like the limiter only engages at the top of the trigger button, so you might break more than the limiter if you try the 600 pound shop gorilla fix...

Sure about that? I thought the did it for swirling the fuel/air mix together. Not so helpful on the exhaust side. I suppose if it's true companies like extrude-hone are belly up.
The texture is called graining and was done so the part sticks to the core side of the mold better, was probably sticking too much to the other half when the tool opened causing stress marks on the part or coming off completely. the 3 lines on the one ejector pin were done by hand in the press with a ball burr, probably during a tryout, to get the part to stick even more to solve the issue. Source I build these things.
This is correct, the part needs to stick to the moving half of the tool, the lines on the ejector pins will be to hold it on the pins so a robot can pick them off.
These are also very useful for getting a metric butt load of heat into fires... Was able to get railway spikes bendable using tongs with one of these and some hardwood. 1 downside is the intake can get loose shirts/shorts caught in it, if you are a right hander

I use it to blow out vaccum filters, clean off tools, get sawdust off roofs, clean surfaces for adhesive. Many different things. Had it for over 4 years now and it works as well as it ever did. The simplest things are the best things.
It's amazing how much I learn from your videos. I never thought about why the shop vac motor revved up when it's clogged. Makesa' sense when ya think about it.
Might have to pick one up for the old mans birthday.

Came with a drill, the chargair, 2 batteries and one of the anemic circular saws. We got our pound of flesh out of them i helped my dad remodel the show room at the john deere dealership where he worked.
NOTE TO MAKITA : Every one of these on an Australian building site has a 10mm bit of hose taped on to the nozzle for blowing cement dust out of 12mm holes that are used for epoxing in rebar. An official attachment would be a good idea 💡
Seeing how it is illegal to blow the dust out of the holes due to silica dust. It would be bad to invest in anything but a hepa filter vacuum for your cement dust problem.
You might have guessed it from the country that also banned 9" grinders cos poor sods can't control one. Now you can't blow dust. An I thought EU laws were fucked up!
I've had one of these for a couple years. Much more useful that you'd think. I use mine all the time. Much easier than lugging out a shop vac or air compressor. And it's strong enough that I use it for sweeping my sidewalk outside, and even a super light-duty leaf blower.

The makita blower has become a standard item on fashion photo shoots, replacing huge expensive fans for blowing hair around. Adjustable and precise. Not enough oomph for a wide shot but for one or two models it does the trick.
If you ever watched the mythbusters episode where they covered a car with clay and scooped out golf ball sized dimples, and even with the weight of the clay, with the dents and scoops out, it got significantly better gas mileage due to the rough surface. I'd imagine they did that for laminar flow benefits, as smooth creates turbulence but rough allows for increased velocity.
It's just the right size as an "indoor blower" to get at sawdust and metal chips, and would probably be great for cleaning under the couch, just blow all the crud out from under it rather than having to push the thing around and scratch the floor.
I have two Makita blowers. I use one for camping and hunting to air up the mattress and fan the fire.the other I use at work for things you'd use a blower for, but I also found a way to hook the vacuum end to my 36v Makita circular saw, and the blower end to a Bucket covered with cloth when I cut work surfaces and counter tops. It cleans up about 90% of the mess. Chooch on, buddy!
Having spent 4 years doing garage doors and openers I can say that split washers do actually work in relatively low vibration environments. Every time a chain came loose it didn't have a split washer on it.
I have a 600w corded version of one of these and it's one of the more useful tools I've found out of china. Amazing for cleaning out computers, drying cars/motorcycles off, getting rid of leaves off your deck. Overall it's a surprisingly good tool. Also use it for cleaning out a school bus, beats the hell out of a broom.
As a carpenter this is an invaluable tool. My workmate as the Makita and I have the Dewalt. They are basically identical apart from colour. My Dewalt has that same ubiquitous Mabutchi motor and 3 speed switch setup. I love it.
They work great. We had a friend come out to help on a timber framing project and had one with him. We all kinda looked a this thing with an "oh brother"kinda look until we saw what it could do. Since then several of us that were on that job have bought one. Thanks
@@scowell Yeah, the glass helps, but the polycarbonate housing is tough, but gummy when abraded, and lots of hot fine junk is going to get embedded there and grind away at that impeller. At least, that's my story, and I'm stickin' to it. Hoping for a postmortem in a couple of months. Keep your mitts inna sink.
I have a similar one (they sell the same model with a longer pipe), it's strong enough for normal things like cleaning a roof or a scaffolding on the construction site. For wet leaf, it's too weak, but for this they offer a 18 V x 2 brushless blower, which is extremely powerful.
@@MikeK7115 I have also some of the 18V x 2 tools, the chainsaw, the big angle grinder, a circular saw, and other stuff for the garden. This tools are awesome, they can replace gas machinery.
When hot rodders port their cylinder head intake runners they leave the file marks on some sections and polish others. Seems similar to the housing pattern.
I used this blower for years to keep the shop clean. I bought the 36 volt blower for lawn care. It is so strong that I also use it to blow dry my truck when I wash it.
Posting at 7:24 in the vid... That texture serves no molding advantage. On a injection tool, the only texture that serves the molding process is sand blasting. That only serves to hide rust damage (as you know tool steel rusts easily), and to allow easier release upon ejection. As for the cuts in the pins (excluding the texture you're talking about) that serves to give the pin traction so it doesn't stress the part upon ejection. My take on the texture you are highlighting is that it serves a functional purpose to the part. It would cost extra $$$ and help the molding process not at all. I'm a Plastics Injection Process Technician of 8 years, I've worked with over 800 different tools.
This is completely outside my area of expertise so take this with a full bag of salt. That texture on the inside might be intentional to create a static boundary layer of air along the surface, separating the fast-moving blown air from the plastic. This would reduce the friction and turbulence on the air that does flow out - it's not quite the oft-cited "golf ball effect" (which pulls air), and is more like the sharkskin effect. You could think of it as confining turbulence to the area around that texture, so it can't interfere with the overall air flow. It might only increase the outlet air speed by 1 or 2 mph or save a fraction of a watt - but that improvement is essentially free. Hopefully some employee got more than the American Standard $25 gift card bonus for the idea.
I have one of these myself and it is skookum as frig! Of course I bought it bare and picked up a hard plastic blower attachment later, about a foot and a half longer, with a 45° bend at the tip. Amazing piece of machinery by Makita!
Best use I have found for mine is getting bonfires started. Super easy to bring with you and just a little power from the blower makes a huge difference starting a fire. Works great for cleaning saw dust out of the shop too.
I have two of these. Milwaukee, actually. Got the big batteries to go with them too. We went to float down a river with the extended family for a week. Shuttling tubes back and forth would have been a pain had these blowers not come with a reducer attachment. When we get to the drop-off point, it only takes seconds to get the float taut. saves on car space for sure and these blowers serve more than their purpose.
Half the time I have not got a flippin clue what you're talking about...not sure you have either,but I enjoy the journey with you none the less. Keep travellin' please
I’ve used the type of blower but AC model almost every day for 18 years with the company I work for and it’s been a great tool with 0 issues, we are now using the Milwaukee 18v cordless and it’s been great 👍 you need to test the one next . Good review sir !👍✌️🇨🇦
I've owned one of these for about ten years. Bought it for the specific purpose of blowing detritus out of my enclosed car trailer. It has come in handy for some other small tasks, as well.
I think the texture is so the part stays to the side with ejection pins, B side. If both sides were smooth when the mold opens the part might stick injection side, A side.
The bumps inside the impeller housing is probably there to induce a turbulent boundary layer, which would delay boundary layer separation compared to a laminar one and allow air to leave the tool at higher velocities.
I've had one of these for 9 years and only in the past months that the turbine wheel has started clicking. Not sure if its the anti static flopping around or the bushing flogged out but still goes hard. I do like the Milwaukee ones as they have a longer nozzle and blow alot harder.
My father bought a whole makita kit when I was yound (Ni-Cad batteries generation) and the previous version of the blower was in the kit. We were like we will never use this thing but whatever it is there. Turns out we used it heavily and still works to this day. However we mostly use it to light the furnace, the fireplace or to inflate air mattresses
Guys how is it we go about trying to get a part made? I have a chromebook that flips around to a tablet my son loves but they built the damn hinges out of pot metal. The stinking things keep cracking and I'd think they would last longer if made out of real metal. It's getting old replacing 2 hinges the size of a US quarter for over $10 every year.
I got a busted DUB182Z. Burnt wirings, terminal lugs and the yellow battery holder. What AWG/ single-core cable size would you recommend? Makita Service Centre can't even fixed it. I'd rather have it fixed myself.
The textured area may well be an area of the mold that has worn, and it's been replaced with an inserted area of the mold to repair a large area ... I would have thought they would have polished the texture out ... ? Surely it causes the molding to stick in the mold or perhaps thats the idea to stop premature ejection of the molded part ... ?
One thing I find interesting about this product is that the design and the molds havent changed in over a decade. My stepfather had one of these when I was just a little kid and they're still being sold exactly the same.
Is this Impeller type the best way to shift high quantities of air in a compact package? Also could they have fit the impeller perpendicular and bent the outlet pipe 90 degrees?
Rough surface flows the air better because there's air trapped inside the pists acting as a lubrication/bearing surface. It also makes the surface last longer when there's sand/dust as it cant rub against the surface.
Interesting to hear about Bernouli. Something I never knew. So true with regards to studying these icons of science and engineering but not knowing the back story regarding their often tumultuous lives. A humbling reminder that oftentimes great minds are still imperfect mortals.
Hey AvE, those differences in color could be due to the fact that different polymer types bond to the colorants at different rates. And will affect the hue of the color. Trying to get the exact same color between different plastics is expensive to do. And those bumps on the inside are probably due to help with the fluid dynamics as well as prolonging the mold life. Glass filled materials are very harsh on the molds. If you have any polymer questions, I can do my best to help!
the texture on the inside could help to actually hold it on the side of the mold that has the ejection pins when the mold is seperating after injecton. there seems to be more surface area on the outside so it would naturally get stuck on the wrong mold part. just an idea from first impressons
AUS\AEG blow-jobber the same, thumb selector is the same setup, physical detent with the brushed motor-,b blow only version, being a right-handed person and with the intake for the blower being on the left, some yard clearups can take longer than they ought. (long time luker, 1st time reponder, 5yr mine worker, go Pilbara!)
I do the injection molding. The texture on the inside of the blower housing looks like a "keeper" feature to keep the mold on the B-side of the mold. Sometimes if you have a really smooth curvy part surface on a mold, you can have a part "self-eject" when the mold opens which can be not ideal. By adding texture you can increase friction in the mold and 'keep" the part on the mold.
But would that not affect air flow, maybe makes it swirl ?
you the man
could it be to cut down on static build-up?
Ranjit Yeah, I'm thinking golf ball dimples that speed up the air velocity but then, why would someone do that..
Otherwise you go to town with the brass pliers when it sticks in the A side.

Probably a lot gentler on the kids too, no marks from the bristles and all...
As a carpenter this is an invaluable tool. My workmate as the Makita and I have the Dewalt. They are basically identical apart from colour. My Dewalt has that same ubiquitous Mabutchi motor and 3 speed switch setup. I love it.
Thank god a proper AVE video. I know the CNC is your new baby and it is interesting to many but please let her have her own channel.
They work great. We had a friend come out to help on a timber framing project and had one with him. We all kinda looked a this thing with an "oh brother"kinda look until we saw what it could do. Since then several of us that were on that job have bought one.
Thanks
Great for cleaning dust of the mitre saw and table saw before they go in the van.
I spy an early prototype of the catapult. You sneaky bastard. Hats off to you.
I am predicting a very short lifespan for the sucking feature...
razor sharp metal shavings processing through a plastic fan?
@@scowell Yeah, the glass helps, but the polycarbonate housing is tough, but gummy when abraded, and lots of hot fine junk is going to get embedded there and grind away at that impeller. At least, that's my story, and I'm stickin' to it. Hoping for a postmortem in a couple of months. Keep your mitts inna sink.
I don't always follow what you're talking about , but your voice utterly ear candy.
I daresay I'm learning something!
I have a similar one (they sell the same model with a longer pipe), it's strong enough for normal things like cleaning a roof or a scaffolding on the construction site. For wet leaf, it's too weak, but for this they offer a 18 V x 2 brushless blower, which is extremely powerful.
Simon Maier those 18x2 tools are mean sum bitches I just got the 18x2 chainsaw and it is very worthy.
@@MikeK7115 I have also some of the 18V x 2 tools, the chainsaw, the big angle grinder, a circular saw, and other stuff for the garden. This tools are awesome, they can replace gas machinery.
When hot rodders port their cylinder head intake runners they leave the file marks on some sections and polish others. Seems similar to the housing pattern.
I used this blower for years to keep the shop clean. I bought the 36 volt blower for lawn care. It is so strong that I also use it to blow dry my truck when I wash it.
could the bumps be like on a golf ball??
disrupts the surface boundary..... allowing for more flow?
That texture from the inside of the part is for demloulding the part, it helps sticks the part on the ejector side
Posting at 7:24 in the vid... That texture serves no molding advantage. On a injection tool, the only texture that serves the molding process is sand blasting. That only serves to hide rust damage (as you know tool steel rusts easily), and to allow easier release upon ejection. As for the cuts in the pins (excluding the texture you're talking about) that serves to give the pin traction so it doesn't stress the part upon ejection. My take on the texture you are highlighting is that it serves a functional purpose to the part. It would cost extra $$$ and help the molding process not at all. I'm a Plastics Injection Process Technician of 8 years, I've worked with over 800 different tools.
This is completely outside my area of expertise so take this with a full bag of salt. That texture on the inside might be intentional to create a static boundary layer of air along the surface, separating the fast-moving blown air from the plastic. This would reduce the friction and turbulence on the air that does flow out - it's not quite the oft-cited "golf ball effect" (which pulls air), and is more like the sharkskin effect. You could think of it as confining turbulence to the area around that texture, so it can't interfere with the overall air flow.
It might only increase the outlet air speed by 1 or 2 mph or save a fraction of a watt - but that improvement is essentially free.
Hopefully some employee got more than the American Standard $25 gift card bonus for the idea.
I have one of these myself and it is skookum as frig! Of course I bought it bare and picked up a hard plastic blower attachment later, about a foot and a half longer, with a 45° bend at the tip. Amazing piece of machinery by Makita!
Both the tool and the Capn Hindgrinder jokes qualify as damn skookum!
the texture is simply ribbed for his pleasure
Best use I have found for mine is getting bonfires started. Super easy to bring with you and just a little power from the blower makes a huge difference starting a fire. Works great for cleaning saw dust out of the shop too.
Think that's giving the golf ball effect keeping the air in the center smoother to create a faster more directed cone of air. But I'm no expert
I have two of these. Milwaukee, actually. Got the big batteries to go with them too. We went to float down a river with the extended family for a week. Shuttling tubes back and forth would have been a pain had these blowers not come with a reducer attachment. When we get to the drop-off point, it only takes seconds to get the float taut. saves on car space for sure and these blowers serve more than their purpose.
Half the time I have not got a flippin clue what you're talking about...not sure you have either,but I enjoy the journey with you none the less. Keep travellin' please
I’ve used the type of blower but AC model almost every day for 18 years with the company I work for and it’s been a great tool with 0 issues, we are now using the Milwaukee 18v cordless and it’s been great 👍 you need to test the one next . Good review sir !👍✌️🇨🇦
I've owned one of these for about ten years. Bought it for the specific purpose of blowing detritus out of my enclosed car trailer. It has come in handy for some other small tasks, as well.
A Correira Who is Detritus and why is he in your enclosed car trailer?
I think the texture is so the part stays to the side with ejection pins, B side. If both sides were smooth when the mold opens the part might stick injection side, A side.
Yes this was my idea as well. If it was a fluid flow thing it would be everywhere in the outlet...
I got that trigger stroke limiter on a late 1980s Bosch drill
The bumps inside the impeller housing is probably there to induce a turbulent boundary layer, which would delay boundary layer separation compared to a laminar one and allow air to leave the tool at higher velocities.
“We need a more rigified dingus in order to actually... *blowing sound*”
Give a man a vacuum and it’ll sit in the corner, tell him he can take it apart, and he’ll clean his whole damn shop!
A man of science and history. I have great respect for those traits.
!!! AvE! I have come up with the REAL QUESTION for this piece of equipment!
How much water will it pump?
@@jeremymcadam7400 per blower?
I've had one of these for 9 years and only in the past months that the turbine wheel has started clicking. Not sure if its the anti static flopping around or the bushing flogged out but still goes hard. I do like the Milwaukee ones as they have a longer nozzle and blow alot harder.
I actually got one of these to use in place of a bellows in my offset smoker. Nothing gets splits of post-oak to conflagrate like a small leaf blower.
Every vijeo is a treat.Thanks Uncle
My father bought a whole makita kit when I was yound (Ni-Cad batteries generation) and the previous version of the blower was in the kit. We were like we will never use this thing but whatever it is there. Turns out we used it heavily and still works to this day. However we mostly use it to light the furnace, the fireplace or to inflate air mattresses
Guys how is it we go about trying to get a part made? I have a chromebook that flips around to a tablet my son loves but they built the damn hinges out of pot metal. The stinking things keep cracking and I'd think they would last longer if made out of real metal. It's getting old replacing 2 hinges the size of a US quarter for over $10 every year.
i think its like a golf ball, has something to do with how the air moves through
I got a busted DUB182Z. Burnt wirings, terminal lugs and the yellow battery holder.
What AWG/ single-core cable size would you recommend? Makita Service Centre can't even fixed it. I'd rather have it fixed myself.
Only two mins in and already some great laughs! Lovin it!
The textured area may well be an area of the mold that has worn, and it's been replaced with an inserted area of the mold to repair a large area ... I would have thought they would have polished the texture out ... ? Surely it causes the molding to stick in the mold or perhaps thats the idea to stop premature ejection of the molded part ... ?
I missed this boltr stuff, awesome video
Really enjoy the tool tear downs . Keep up the good work
Makita is my favorite brand of tool
One thing I find interesting about this product is that the design and the molds havent changed in over a decade. My stepfather had one of these when I was just a little kid and they're still being sold exactly the same.
Just bought one of those myself very glad you gave it the proper skookum rating it will be my regular shop cleanup blower as well.
The ruff surface is for pulling . Meaning to keep the part stuck to the ejector side of the Tool
Is this Impeller type the best way to shift high quantities of air in a compact package?
Also could they have fit the impeller perpendicular and bent the outlet pipe 90 degrees?
Rough surface flows the air better because there's air trapped inside the pists acting as a lubrication/bearing surface.
It also makes the surface last longer when there's sand/dust as it cant rub against the surface.
could the textured surface help with the acoustics possibly?
I wonder if the people that know you truly appreciate how funny you are.
I suspect that the knobbly bits on the inside of the clamshell would be a sacrificial wear layer for the abrasive particulates when she’s set to suck.
I have the dewalt version of this and it's ok same trigger same rubber dingle blower but it comes with a attachment to fill pool float toys.
Interesting to hear about Bernouli. Something I never knew. So true with regards to studying these icons of science and engineering but not knowing the back story regarding their often tumultuous lives. A humbling reminder that oftentimes great minds are still imperfect mortals.
Hey AvE, those differences in color could be due to the fact that different polymer types bond to the colorants at different rates. And will affect the hue of the color. Trying to get the exact same color between different plastics is expensive to do. And those bumps on the inside are probably due to help with the fluid dynamics as well as prolonging the mold life. Glass filled materials are very harsh on the molds. If you have any polymer questions, I can do my best to help!
Oh AvE... how I love your videos.. been a subscriber for a while now.
the texture on the inside could help to actually hold it on the side of the mold that has the ejection pins when the mold is seperating after injecton. there seems to be more surface area on the outside so it would naturally get stuck on the wrong mold part.
just an idea from first impressons
I'd think they would have just added some undercuts to accomplish that rather than texture it.
Could the bumps inside of the air inlet used for lowering the noise off the inrush airflow? I dont know just a thought
AUS\AEG blow-jobber the same, thumb selector is the same setup, physical detent with the brushed motor-,b blow only version, being a right-handed person and with the intake for the blower being on the left, some yard clearups can take longer than they ought. (long time luker, 1st time reponder, 5yr mine worker, go Pilbara!)
Coffee, toast and marmite and a little AvE on a Saturday morning, life don’t get much better than this!
It does, you forgot bacon :)
MiH1IT indeed I did, thank you for correcting my egregious error! :)
The internal rough surface is most probably wolfram treated the mould to aid seperation since the injector pins have this texture as well.
