I have a look at the construction and components in the battery power DeWalt air compressor. I wasn't expecting much and this lives up to those expectations.

For leakproofing railcars we always use flax yarn and flaxseed oil. The teflontape does not hold up against all the vibration that a freight train produce. Railcars also experince quite extreme temperature differences and is always pressurized with 5 bar. These pneumatic couplings also have to have a lifespan of 30 years+ and again flax yarn is really the only thing that holds up over that much time if applyed correctly!
Flax-U... sounds familiar... Back when I was crawling around in hulls to obtain a few doll hairs, I recall wrapping flax rope around shafts to then tighten the gland nut just enough to release the schmoo... Usually in a dark damp bilge in an attempt to mitigate a leak in saturated old vessel... Maybe that is where I heard of Flax-U?

Oh LMAO. That's funny. Only because we've all done that. I took my 1990 ford ranger dash apart one time and was surprised to learn how much more complex I made it then it should have been.
or it's for balancing/sliding the box around while the weight is being supported under the flaps of the box where the other failure mode is. p.s. did you really leave this comment 1 week ago?
I worked for the company that made the pop valve on there, it's a machine shop in Fenton, MO called Control Devices. IIRC they're on all Black & Decker compressors. Pretty cool process of making and staking them, and even more cool to see it all the way up in Canada! For those interested, the parts are made on Hydromat precision transfer machines, then assembled and pop-tested in house. When I left the company, they were in the process of making a new testing / staking machine for more accurate pressure relief PSI, per B&D requirements.
I work in industrial compressor automation, we buy so many parts from CD. Think we've got some pop valves, mufflers, and check valves on the way from them now! Love those folks, they're one of very few vendors I've never had issues with in regards to quality and accuracy in orders.
This has got to be the most comprehensive tool review channel ever. You don't just get to see the tool working. You take it apart, tell how each part was manufactured, the materials they used to make the various parts, the likelihood of parts lasting or failing, and if the sum total of parts is any good or not.
Great Content. Love hearing you talk about manufacturing processes. As a fresh grad I've found that the most valuable resource I can have is an old gray-beard willing to share. Thanks for adding so much to my stock-pile of ideas.
I'd argue that the feet being as soft as they are is actually fairly well thought out. You get the same soft kind of rubber on some computer fans, what for dampening damping whatever you call it the vibrations. At the very least, it won't chase you around the shop when it's running, if nothing else.
If the feet are too soft then they may deform over time until the machine rests of the plastic. But yea, if they are just firm enough then they will cut down on vibrations transmitted to the surface the compressor is resting on, and might help keeping it from escaping without help. Without getting my mitts on one of these I really can't tell how the feet will perform, so I'll just wait for the tests.
That hole in the cylinder is more than likely to bleed pressure so the crank gets past a certain degree so not to lock up when pressure is high!!! If it started compressing at the bottom of the stroke when pressure is high in the tank it could lock up the motor!!! So by bleeding the pressure for a few degrees it allows the crank time to build speed to drive through the wall of pressure it incounters on every stroke!!! Just like on high compression engine's the exaust valve is left open for a few degrees before compression begins!!! That way you don't lock up the stroke at bottom dead center!!! You can't start compression at bottom dead center!!! You run the risk of bending your rod!!! I also believe that the rod is most likely a powered metal rod,not a casting!!! Just like in car engine's!!! Keep Rocking it out!!!
The 4 stroke's motor intake valves close after BDC for a different reason: since the intake valve cannot be opened instaneously (at least not for now, Koenigsegg is still developing an electromagnetic valve control system), closing it at BDC would simply not give enough time to intake all the air the motor could. So, the valve is kept open for a longer time.
@@pum882 electric solenoids will not do it instantaneously either. Anyways pneumatic valve springs exist and are a proven technology that has been limited on how fast it can rev a tad over 20k rpm because of things such as flame propagation speed etc etc. At 20k revolutions in a minute a valve is as close to instantaneously moving as it can be a damn solenoid trying to do things electricity actually cant even do given the quickest thing in the universe is still not instantaneous stop using this word when its impossible alright
@@pum882 at bottom dead center the intake system is still charging the cylinder because of the drop in pressure closing it abdc allows the process time to complete. It closes the piston moves up the process is then converting the chemical energy of the fuel and air into force. The piston then moves up and the exhaust valve opens. Opening a valve quicker requires more spring tension to retain said valve. So really the whole free valve thing is a joke given what he showed off was less impressive than current technology that is actually newer
That cloverleaf is the National Board of Boiler and Pressure Vessel Inspectors symbol(a USA thing). In Canada pressure vessels should have a Canadian registration # (CRN#) but is only required over a certain volume (42.5L i think?) at least here in Ontario. BC law may differ..as usual. Great video, thanks!
Hey AvE, the piston cup is a formed PTFE wafer (likely a bronze or ceramer filled ptfe) machined flat from a solid PTFE rod and formed when it's knifed off or cup formed later - not PTFE coated metal like a DU bushing. The metallic part is just a spacer that holds it down.
7:44 and I just want to say thank you for the breakdown of this compressor. It's something I've wanted for a long time. $300 no battery when first released. Then a charger and 6amp flexvolt was added and the price never changed. That's how long I've been aiming and still have not pulled the trigger on this purchase. This video may well be the reason I buy or don't buy this unit.
Regarding your comment at 5:55 - I'd suspect they put thought into the feet and chose the soft feet for at least two reasons. First, they'll help keep the total noise down by reducing the energy that transfers into the surface the compressor is resting on. Second, the soft feet are selected based on the (relatively) low frequency vibrations of the machine. Soft feet will reduce the likelihood of the machine walking around on its own.
I think the unloading hole on the cylinder is so that it doesn't see any resistance from the piston during the first part of the compression stroke. When the crank arm is at a right angle to the piston rod, that's the point of worst mechanical advantage. Since Reed valves don't care where the piston is they have to relieve the pressure that way. Also probably why we don't see you too many VFD compressors yet. Part of what gets it through the compression stroke is the momentum it gains during the intake stroke. Running at lower RPM would take a lot more torque.
What a potential with that brushless motor and the brainbox -- as you says; with a pressure transducer and a couple of thermo couples that would be an awesome tool. Most of the applications where I use an air compressor I'd really like it to be more pro-active, not that I'd require machine learning to predict what I'm bout to do. But more that when I fire the first nail it should start revving up and be ready for the next nail as it usually comes right after. And I have a pneumatic bottle capper for bottling my home brewed beers where this kind of control would have been perfect. My small shop compressor with its 3 bar hysteresis only work decent in the 8-6 bar range and when it dips below 6 bar it will not press the caps on 🤬.
31:28 I immediately thought to myself "That's going to get over-torqued and smoke the bearing when he re-assembles it"....until I noticed that cool little feature in the casting to help mitigate exactly that. Very cool. Edit: and apparently I should have waited to comment that. Premature Commentation....embarrassing. Also, those holes in the cylinder wall are to reduce the required 'startup' current when the compressor kicks on. At operational speed they'll have a negligible impact on volume, but allow for a much smaller motor & higher pump ratio.
I hope to whoever owns this universe that you are going to be my teacher in our next life. I have already learned a lot from you and I need more, more!!!

Can't wait for part Deux.
Made in the USA with global materials means the tool is assembled in the USA with some US content. Profits come back to US as well, which are being invested in new tool factories like the Stanley/BD tool factory in TX to be opened at years end. Hand tools, inc. Craftsman!, will soon be made in USA again which is a good step forward.
@@jm5912 The "Content " Can very well be just the assembly process. There isn't a content requirement other than the final product has to be substantially different than the parts.
In Canada, there are minimum volume and pressure requirements which need to be met before certification is required. This likely meets neither which is why there's no stamp. I could be wrong as it's been a few years since I was in the industry.
It gets messy since it depends on the purpose of the pressure vessel. But 15psi and 1.5 cubic feet are exempt in Onterrible. The way the codes are phrased its more like everything is a pressure vessel, with these very specific exceptions.
I've got one of these, been using it for about 8 months. Works good enough for what it is. Saves me a little headache plugging a compressor in in every room as I trim out

I’ve found that Swack ptft paste is the best stuff for sealing Npt threads. Also most uk oil and gas instillations banned the use of tape due to accidents and clip-board warriors. Saying that when used correctly the combination of the two can work miracles. Side note people who use thread lock to seal threaded fittings really grind my gears.
In the UK, pressure vessels are only considered worth worrying about if they're over 200 bar litres. That is 20l at 10 bar or what have you. That means that small compressors (often 24l, 8 bar) you don't need inspections etc. A reason similar to that might be why there's no tag on your tank.
Haven't watched the video yet, but is the air connection cordless too? It would be so convenient to not be tethered to the compressor while I fill my bike tires
I think that since the piston and the rod are a single piece (there's no wrist pin), when the rod is at high angle in respect to the crankshaft, the piston cannot hold the pressure. So there's no need to build up pressure in the cylinder before the piston reaches a certain height. All the pressure built prior to that point would be lost, so the holes simply prevent it, in order to save energy. I hope you understand what I mean, English is not my everyday language.
I was thinking the reed valve may keep the pressure slightly negative (psig) at the bottom of the stroke so the hole lets air in to get to 0 psig before stroking up.
I was wondering about the piston sealing at what you call high angle, that I just called weird angle. I thought maybe the business end of the piston had some roundover to handle that but now I realize that it would have to be an oval to seal at that angle (projection of a circle being an oval and all that)
Mad Zit An oval piston wouldn't fit at the straight angle. A spherical piston (part of a sphere) would keep it's cross section but sealing is beyond me.
I have one of these in the toolbox of my truck. It's great for camping or out riding sxs. It'll run a framing gun in a pinch and much better than hand banging small framing jobs together
The 20V range of tools in the US is marketed as 18V in the UK. The flex volt stuff drops from 60V to 54V. The battery packs seem to have the same number of cells, as they are the same size. I'm wondering if there is a different imperial volt (as opposed to a metric volt ;) ) or if the goalposts are further apart on the honesty scale.
Actually has more to do with advertising, technically these batteries will read 20 & 60v if you were to throw a meter on them while disconnected from the tool. However if you were to measure the output while being used they will read 18v or 54v or even in 12v tools they will read 10.4v. So not necessarily a lie more of a technicality the batteries will not supply a constant 20v but they do produce it.
The HPC just released an interesting video on their regular vs hydraulic vise and the force sensor. I'm sure you'll see it soon, but it might deserve a follow-up to your previous endeavour about grip strength in CNC machines.
I believe the tank doesn’t have the ASME stamp because their standards aren’t applicable to pressure vessels that are less than a certain size, I’m not 100% sure of the number but I think it’s 5 gallons.
A friend from a forum actually told me just recently to put a bit of PTFE tape onto the bleeder valve on my brake calipers. It doesn't seal it when it is shut (that's what the tapered end does) but it does prevent air creeping in through the threads while bleeding the system. Works a treat, I need more PTFE-Tape to put it into all the threads.
I learn so much from the spontaneous aside chats. Keep it up uncle B. I liked the chat about the npt and bpt and jic. Now I'm going to go and give my swagecock fittings a hug... My first job with them was a argon system with about 25 connections. No leaks. Holds 1500psi for a week. I know large molecule yada yada thats easy. But still its a piece of piss and cheaper than a pipefitter. Keep your stick in a swage.
Ave ,found ur channel few months back ,awsome an finally someone with some hard to find usable info about the tools an such that people use in average or even above average garage,shop,or kitchen table when the ol girl gone out for the day ha!thank u. Could use some repair or remolding info on 6-12 battery chargers as i have about 10 of them in a pile that im currently triping over an also maybe on tread mill permanent magnet motors. Like to wire to run without controller if possible. Thanks a ton.
Being in an industry that does a lot of screwing, we use mostly the parallel threads and not the wedge one you mentioned which is called tapered thread. The reason being we found that if we had a leak on a tapered and stripped it out the female side was in most cases expanded due to someone tightening the fitting too far in. Consequence being it was really difficult to get a tight joint the second time
So you take electrocity from the wall and stuff it into a battree. Then take the wrangled pixies from the battree to spinamathing the compressor to hold the residual power. I think it would be interesting to find out how much energy is lost in the two processes it takes to run the compressor, charging and then pumping, compared to a standard compressor.
@@johnfrancisdoe1563 but they dont transmission and efficiency loss is loss. Just because they are the same in both directions doesnt mean they are suddenly not a loss.
I believe your correct on the unloaded. When that top reed gets damaged by the heat and back fills into the compression chamber they don’t want to restart the compressor with say 70 psi at bdc causing a higher startup current. The pressure would push the piston down, uncover the hole and bleed off.
Pipe fittings is what I do in my new job, supplying piping and fixtures for fire hydration systems. Everything is tapered threads. We use hemp fiber for pipe seals. Because its plant fiber, it expands if it gets wet and strengthens the seal. It also makes on the job adjustment easier and less likely to break the integrity of the seal while adjusting,
Had one of these compressors. Ran 2 minutes, locked up and blew smoke. Took it apart and found one of the 4 screws that fasten motor to crank housing jammed in-between cylinder and connecting rod. Other 3 screws laying loose. They were never screwed into the motor housing!
What an awesome video. I've had this DCC2560 for about 3 weeks and it stopped working. DeWalt send a replacement and suggested I scrap the one that stopped working. Given it's only three weeks old, I'd really like to tinker with it myself to get it working. This helped me figure out how to get it apart and how it all works. If I get it working, I'll let you all know what I did to fix it.

Haven't read every comment (maybe someone else pointed it out)... There is a small nuance: When it says tested "per" ISO 1217 it doesn't say tested "To" ISO 1217. This is a way the Marketing wankers weasel the consumer. Usually using the word "per" allows for a company to create their own procedure which is based on a standard. This allows for a bit of latitude but does not assure full compliance.
Unfortunately it won;t work legally. There is a rule of interpretation in law, wherein however a reasonable person would interpret a statement, it how it will be taken no matter then literal meaning of the words.

You are the first person I have heard correct themselves when the say “suck”; explaining that it’s actually pushing into a lower pressure area. I do it often and people look at me like I’m nuts. One of those weird memory nuggets from 7th grade science that I’ve can never forget. Don’t get me started on lift hahahaha.
I have soldered a brass bicycle tire valve from an old tire to a car freshener spray can for a shitty compressed air bottle. I did the due diligence of looking up the rated pressures of garden variety spray cans and my pump will do 10 psi at most, which is well within range. And soldered it facing away from the user. And tested it inside a steel cage, bringing it up for pressure and letting it sit there for days. Works fine.
I have one of these compressors it isn’t strong but it will take you out of a jam if you need it. The way I looked at it was either buy all new battery powered nail guns which aren’t very good or have a battery powered compressor which has a lot of uses. I never thought of it as a very “good” compressor but it gets the job done. Love the vijayos keep it up
It'd be neat if they made it where you could plug it into the wall as well as with the batterias. I've got a 300cfm blower fan at work that has batteries but you can just plug in any old extension cord into a socket behind where the batteries go
I think it would be pretty cool if you made a Arduino based 3phase controller to really see what it can do. Maybe even put a clamp on heat sink fins to the cylinder, which are cheep and easy enough to get. A pressure release solenoid to create a cooling cycle. So many possibilities. Great video 👍.
I once bought a "super silent" compressor, only 40db! When I did turn it on at home, it was so loud that I had a hard time to her my self shouting. I turned out that the 40db was measured outside at 30 feet distance! :-)
Thank you Ave. I'm very uncomfortable with NPT my self. I use teflon tape plus thread sealant to shut them up. Next time I will take your advice. Burn the MTF to a crisp and insert!
I appreciate your channel because it reminds me of all the stuff I learned following my grandfather around in his shop doing whatever bullshit project we were working on. Half the time I think we did projects just so he could get some peace and quiet from grandma bless her heart :D
I work at amazon I'm in packing rn but i have been trained in loading the truck by hand with all of the boxed for fedex ups and plenty of other i also have packed a crap ton of these dewalt compressors. We also have to include that there hazmat label in the begining which means it can't be shiped by air and other things. If we don't amazon gets fined but usually amazon is on top of that kind of stuff because the main conveyor belt that sorts the packages kicks out the item without the hazmat label and i think gets sent to problem solve it's pretty cool.
