I also mentioned this on the patreon, but a tight sliding fit is exactly what you want on the rear bearing. The rotor must be constrained radially by the rear bearing but it must be free to slide axially to allow the rotor to expand and contract with temperature changes. Only the front bearing is used to locate the rotor axially. If both bearings are trying to locate the rotor axially you will get large axial loads on the bearings when the rotor gets nice and toasty.
I kept staring it, wondering if it was going to get popped off at some point - or if the NSA goons were going to bust in after they were notified that it had been directly exposed to air and light for longer then "necessary".

I would love to see the "36v" brushless recip saw apart! I've had mine foe a year or so and love it. It is definitely powerful and built like a tank, I was using it up in a forklift man basket outside and stupidly needed that extra inch and open the gate. It was snowing and slick as shit up there i went to grab the saw and lean out slipped and fell out of the damn thing lucky i was holding onto the foreskin part of the saw and it was hanging by the built in hook on the rail of the basket and sure enough I held onto that thing for dear life 20' above concrete and the saw didn't break and I was able to pull my scrawny 150 pound ass back into the basket. Thank you akita for making a skookum tool!
The big aluminum and potted controller is almost certainly the motor controller. You can't see mosfets on the potted side because they are probably mounted to the other side of the board and pressed up to the aluminum heatsink for dissipation. Then there are the three thick wires for the three phase to the BLDC motor.
@@laboulesdebleu8335 you can't really. One of the points of potting material like that is to keep prying eyes from seeing how the thing works. That stuff is really hard to pull off and you may end up pulling components off with it. It's just not worth it to take things like that apart

These makita subcompact sawzall are great, mine gets used constantly, even used it for cutting up tree branches and roots. The small size makes it a seriusly usefull tool. I dont bother with my full size sawzall now for site work.
Thanks for this. I was sitting on the fence on one of these as my current one has grown a wee bit long in the tooth. The compact size appealed to me, but I was really hesitant on if corners had been cut. I'm extremely impressed with the build quality, this was the final push I needed.
Big fan of Makita. I have Dewalt, Craftsman, Makita, and Milwaukee battery powered tools. I use my Makita, and Milwaukee tools at work in the aircraft industry. My Makita drill (5 years) and impact (10 years) have been indispensable. The only failure I've had was the charger after 5 years. The Milwaukee (1/4 drive ratchet) came about 3 years ago. Awesome tool and well used without problems. My Dewalt (5 years) and Craftsman (8 years) drills are home use and so far no problems, but have never been used in harsh ways. I do a lot of research before I make a purchase and luckily its worked for me.
I like my dewalts but makita are definitely keeping their production standards higher these days. The anvil on my dewalt impact is loose af, bugs the hell outta me.
I've been really impressed with all of the 'sub compact' tools Makita has put out thus far. This saw particularly. Nice to see the innards, it feels plenty solid in use but seeing why this is so is reassuring. Would love to see you do a BOLTR on the sub compact rotary hammer. It has some kind of pneumatic impact mechanism which seems strange to me, but the thing works really well. For tapcons and sub 1/2" holes in concrete its the best rotary hammer I've used. Its as light, or lighter than others 12v tools to boot.
I was lucky enough to find this exact mini Sawzall at Home Depot (incorrectly priced on the clearance rack for $59 US). I didn't need one, however I couldn't pass it up for the price. Nice addition to the rest of my Makita 18v tool collection. Little sucker works great.
Great video, your knowledge is appreciated. It’s nice 👍 you assume viewers have a basic understanding. The manufacturing process description is always interesting. Bling on the outside does not equal guts on the inside. I’ve been a planker 50+ years. The boarding vids are a nice touch.
i have the full size one of this, great tool, cuts through anything, steel, aluminium, trees, anything. enough power depends on the blade, chews threw battery almost as much as the angle grinder
Just bought this unit I have Makita tools but the sub compact line or the black tools always kinda made me wary. Glad to see you took one apart and reviewed it 👍
On RC airplane brushless speed controls those capacitors are generally to reduce the arcing when plugging in or unplugging the battery. They often have long leads like that also.
You can believe that Makita does watch this channel. All tools are engineered from field suggestions. Just like the new black tools which are a new family called sub compact. They are light and small by design for tradesmen who have to have a tool in their hand all day long but do not need the power of the bigger compact class. Keep up the good work.
I use this every day at work and I let coworkers use it and I loooove it it's no heavy demo saw though ***update*** it got run over by the fork lift it's still been working though.
I once bought 30 Milwaukee hand drills for my guys in NYC. After having each guy sign for them they went on their merry way. After about 40 some days the shop steward set up a meeting with me to inform me that the drills do not conform to their union guidelines and would all have to be returned. I asked him why he waited all this time to tell me and his reply was " I just took mine out of the box and noticed the problem". The "problem" was that it had a hold down trigger and this was unsafe in the union's eyes. Sooo I sent out a message to the guys that they would have to return the "problem drills". Well ( I hope your still with me ) the drills started to come back. Forget about the boxes, forget about the beautiful gleaming chucks the nice red handles now I had a pile of used equipment, all signed with their names, on the handles, with permanent marker. Needless to say the vendor would not take them back. My gorillas are lighter then yours weighting in about 250 lbs. We are talking about union steam fitters. Well how did it turn out ? They received the new union approved drill plus their "used" drill, for home use only ! Except for the shop steward, I was able to return his, with the box and he did received the new approved drill !!!

Someone might have said this already but here goes - the electrolytic capacitor is added to reduce the ripple current to the motor as the power transistors are switching. Same reason you'll see the same thing on your VFD. Great vid
at low duty the ripple is very high. I think the flying electrolytic is to keep plenty of charge at high side of inverter when voltage dips under load...
This video sold me on one of these. Just got a nice two tome version and it's been great so far. Really feels well made. I immediately went and cut through some 2x4s to test it out. No need for the full size now that I've got this bad boy.

The black tools are Makita's new-ish sub-compact line. Intended use is, afaik, for people like cabinet fitters, who don't have a lot of room to use regular-sized prosumer tools. Side-by-side the black ones are considerably smaller.
@@djvasforever the black color was originally only on sub-compact tools. The compact drill and driver set from a few years ago. Dunno if it's still the case, haven't shopped for tools in a while.
I remember you asking about battery size for round lithium-ion type, in another vijay-o. If you haven't learned already, the size is usually on the side. 18650 is the most common size. 18 is the diameter in mm, followed by the length. The last digit is a designator reserved for the manufacturer but they usually don't use it.
Those tapers... I'm not sure that's a feature as much as it's just to match the draft of the casting. Save a drilling/boring step. Or maybe it's one of those "two stoned birds" things.

I got a Dewalt compact, it runs good. No quarrels with it so far had it for about 4 months. Use it to whack off kitchen arm stub outs. I used to use a hacksaw, still Much better then ole Mofongo the Dwalt 60v Sawzall.
The capacitor is actually to protect the MOSFETs from the batteries, or more accurately the wires connected to the batteries. Those wires have inductance, so when the power is switched off by the MOSFET (which happens a lot- the PWM carrier will be 2 kHz or higher) the voltage will spike as the magnetic field collapses. This can easily be enough to overvolt and blow up the MOSFET, so they add a capacitor to smooth it out.
Great video. Hey What would you say would be the cause of one of these to keep cutting out. I had it to a shop and they said a controller. I looked up controllers and there are two of them. One is about $90 and the other is about $200. The tool barely has any hours on it but unfortunately it is off warrantee now but I'd really like to fix it myself (shop said it wasn't worth it). The problem started after cutting drywall overhead. Any advice would be appreciated. Thank you for the time.
The bearing fit is probably quiet loose on purpose. When the motor gets hot the shaft lengthens and would cause additional axial load on the bearing. All the axial position is defined by the upper bearing, the lower one is just for radial forces.
The biggest flaw I've seen on my Dewalt 20v tools is that sorry rail design for the batteries to slide in and out of. I'm absolutely tired of jerry rigging the plastic with a soldering iron to get better connections. Beyond pissed at trying to cup the battery with one hand while trying to saw through pvc pipe. Even more disconcerting is the fact the tools and batteries are in a plumbing van in south east texas. I have the original batteries from five years ago. They still work.....if I cup em.
@@Chrominance87 kinda like cupping the of the testes by the other team . It gets better pixie continuity between the battery and the tool prongs. And let me tell you what , it sucks doing it on a sawsall.
Most somewhat newer and almost all newer cordless circ saws you only have to hold the safety button to start it and as long as you hold the trigger you can let go of the safety
I bought one of these today and used it to trim some 2 to 4 inch branches off a myrtle tree. This thing chewed it up... My only complaint is that my hand was numb after awhile, so maybe you'd want a hearty glove to dampen the vibration.
I watched dis earlier and had a good tink about it. I believe the slop in the bearing fitment is to allow for swelling do to heat. I use these brushless motors in RC airplane's they tend to get hot and they are in open airspace. Maybe.
I've got the ultimate "hot supper" test material for future sawzall tests... Nitronic 60. One of the extremely limited few items I've ever recovered from our waterjet tanks that wasn't totally eroded to sh*t by the jet passing overhead for other cutting operations.
In the radio control vehicle world, the capacitor(s) are used to protect the circuitry in the esc, not the battery, from ripple voltage. 21:33 you can see it's a 4 pole motor (interesting magnet retention system btw) meaning each of the 3 phases is firing 4 times per revolution. You can see this creates a situation where battery voltage is fluctuating rapidly which, according to an esc engineer, creates some nastiness that electronics don't always like. The lower the quality of the battery, the more ripple voltage which equals more nasty noise/harmonics electronicals don't like. Capacitors smooth this out and provide a nice little kick at motor startup as well.
Its likely that they were able to mount smaller mosfets due to the increased heat sync size (relatively speaking) as well as by picking a black potting compound (which is a better radiator than any other color) which is why you didn't feel any beef mosfets.
Looks close enough to the same as the Dwalt on the outside. I've used said Dwalt it on just about anything needing cutting. If it doesn't shake the soul out of you it does pretty good.
You have to let one of the two bearings float (maybe preloaded with a wavy washer) due to elongation of the shaft due to temperature change. And that electrolytic cap is probably there to provide a well of current for the brushless drive to pull from during transient peaks of torque demand.

I seriously have no clue what 80% of what you describe actually does. But I still wind up watching all your videos. And, in this case, I was needing to buy one of these suckers, so have a good idea what to look for and know Makita isn't half bad. So, again, thank you, and you're funny as hell and I appreciate it.
Nice to see Makita still building good tools even if it made in China. Eventually we will fall out with China and we won't be buying anything from there.
I have a similar model of the makita 18v brushless sawzall. The switch melted after about 6 months of moderate- heavy use. Looks like the same switch in this model.

One is about $90 and the other is about $200. The tool barely has any hours on it but unfortunately it is off warrantee now but I'd really like to fix it myself (shop said it wasn't worth it). The problem started after cutting drywall overhead. Any advice would be appreciated. Thank you for the time.
Mines doing the same, couple of pumps then nothing.
I have the same problem. The saw was unloaded for several years and broke down. It works at low RPM, but stops at high RPM
Greatest channel on SchmooTube.
Always love a Makita BOLTR! Keenly awaiting 14" Makita 36v brushless chainsaw teardown and analysis. I better sign to patreon.
How am I supposed to blame the manufacturer and ask for a new one if all the markings are worn right off? Wait a second, now it makes a sense!
The bearing fit is probably quiet loose on purpose. When the motor gets hot the shaft lengthens and would cause additional axial load on the bearing. All the axial position is defined by the upper bearing, the lower one is just for radial forces.
The biggest flaw I've seen on my Dewalt 20v tools is that sorry rail design for the batteries to slide in and out of. I'm absolutely tired of jerry rigging the plastic with a soldering iron to get better connections. Beyond pissed at trying to cup the battery with one hand while trying to saw through pvc pipe.
Even more disconcerting is the fact the tools and batteries are in a plumbing van in south east texas. I have the original batteries from five years ago. They still work.....if I cup em.
What is this "cupping" you speak of?
@@Chrominance87 kinda like cupping the of the testes by the other team . It gets better pixie continuity between the battery and the tool prongs. And let me tell you what , it sucks doing it on a sawsall.
@@ChrisGilliamOffGrid I have used the 60v battery on a 20v grinder. It was impressive .
Reason I haven’t been inclined to upgrade from my 18v unit. Been rock solid for years, just needs a goin over to restore peak function!
Most somewhat newer and almost all newer cordless circ saws you only have to hold the safety button to start it and as long as you hold the trigger you can let go of the safety
Could you do a review of different types of plastics?
I bought one of these today and used it to trim some 2 to 4 inch branches off a myrtle tree. This thing chewed it up... My only complaint is that my hand was numb after awhile, so maybe you'd want a hearty glove to dampen the vibration.
"We pass the slavings on to you..." That's comedy gold right there. I don't care who ya are!
I watched dis earlier and had a good tink about it. I believe the slop in the bearing fitment is to allow for swelling do to heat. I use these brushless motors in RC airplane's they tend to get hot and they are in open airspace. Maybe.
Can't wait for this goodness! Process faster TH-cam!!
I've got the ultimate "hot supper" test material for future sawzall tests... Nitronic 60. One of the extremely limited few items I've ever recovered from our waterjet tanks that wasn't totally eroded to sh*t by the jet passing overhead for other cutting operations.
The whatchamahoozit on the doodimunculus thingadinger is pretty neat though.
In the radio control vehicle world, the capacitor(s) are used to protect the circuitry in the esc, not the battery, from ripple voltage. 21:33 you can see it's a 4 pole motor (interesting magnet retention system btw) meaning each of the 3 phases is firing 4 times per revolution. You can see this creates a situation where battery voltage is fluctuating rapidly which, according to an esc engineer, creates some nastiness that electronics don't always like. The lower the quality of the battery, the more ripple voltage which equals more nasty noise/harmonics electronicals don't like. Capacitors smooth this out and provide a nice little kick at motor startup as well.
where is the reverse switch?
I use my Knipex to pull arrows out of trees, no idea how they get in there.
I love that the captions are always near impossible to comprehend on your videos. 😂
I miss the teal. :( Looks good though. I may purchase at some point.
As a non contributing freeloader of your content thanks for the entertainment AvE!
Looks pretty well built. Especially given that it was probably assembled by 10 year olds in the Chinez-eum factory.

Think nuke-euler + Cheez-itz™✓
That's because they have small fingers
@@stevenreynolds40 that sleeve.. i dont know if a frail child couldve tangled with *that* beast
Thoroughly enjoyed this one. And it wasnt just the reciprocating shaftsss
It always seems so incestuous when a power tool is taking apart another power tool.
It's a dog eat dog world out there!
Step-drill, what are you doing?
Its likely that they were able to mount smaller mosfets due to the increased heat sync size (relatively speaking) as well as by picking a black potting compound (which is a better radiator than any other color) which is why you didn't feel any beef mosfets.
I think Omron manufacturers switchers for keyboards as well.
Anchor Bait typically used in mice vs keyboard
@@maxbls16 ah OK. Maybe mice just don't publicize what switches they use as much as "gamer" keyboards do
Looks close enough to the same as the Dwalt on the outside. I've used said Dwalt it on just about anything needing cutting. If it doesn't shake the soul out of you it does pretty good.
I would love to see more borch professional!
Yes pls.
AvE on the ball, whacked it good and didn't even tip the tee.
PCB board?
Never knew he worked at the Department of Redundancy Department
Like ATM machine, and hot water heater......always gets me....
vin number
Love my hackzall for EMT and such in tight spots in ceilings and walls and holes and whatnot.
TOT called he wants his sweater back.
The commercial that followed is broadcast was priceless. The opening shot was a big old Oscar Mayer dingus mobile
Anyone who wants the good bit. Skip to 18:00. Choo choo
You a foamer?
You have to let one of the two bearings float (maybe preloaded with a wavy washer) due to elongation of the shaft due to temperature change. And that electrolytic cap is probably there to provide a well of current for the brushless drive to pull from during transient peaks of torque demand.
Those fawkin deadman switches, they to learn from the 2A community and have a manual safety or trigger safety ala Glock.
...and Glock magazine-shaped batterias. GlockGlockGlockGlockGlockGlockGlock
you were a bit early on the hackzall, the m12 fuel (brushless) is vastly improved over the one you compared to in the video
Do you think AvE watches Project Farm? :D
802 Garage I also watched project farm, boostedboiz, pfi speed, lockpickinglawyer, Jennie’s garage, this old tony, and a few more. I say that because I see you everywhere on TH-cam
Well, I bought the tool. Had a chance to use it a bunch. Pretty happy with it.
i think there is a makita engineer that watches this channel.
make that a hole department
well yeah all the brands are watching they have social media departments. ;)
Yea definitely the hole department !maybe even the shovel department too they work closely together
@@JimBo-zb9or Lol
I seriously have no clue what 80% of what you describe actually does. But I still wind up watching all your videos. And, in this case, I was needing to buy one of these suckers, so have a good idea what to look for and know Makita isn't half bad. So, again, thank you, and you're funny as hell and I appreciate it.
was that a windshield wiper motor in that thing
@Another Millennial lol
Well, with four likes there are at least five people here who've never seen an old windshield wiper motor. :D
I cant stop watching since i found this channel! Starting to effect my company, i just keep sitting here watching video after video
Nice to see Makita still building good tools even if it made in China.
Eventually we will fall out with China and we won't be buying anything from there.
Good prediction on Chy-na
I have a similar model of the makita 18v brushless sawzall. The switch melted after about 6 months of moderate- heavy use. Looks like the same switch in this model.
