Lubrication whilst machining is a thing. Copper shouldn't be all that difficult honestly. Annealing copper might make it easier to cut with the CNC bits as well. But in general most metal workers will indeed put a drop every so often while drilling and machining.

[@Worrsaint]

Copper is not difficult. Something like copper would absolutely benefit from oil. Annealing it actually makes it more difficult to machine due to it already being soft and gummy.

[@BRNKoINSANITY]

Those grooves are not to guide the fluid, they increase the surface area in order to aid heat transfer. There is a noticeable difference between a smooth block and a finned block as you increase the load and radiator size.

[@BRNKoINSANITY]

Also, if you fit an o-ring too tightly, it can't compress correctly for a good fit. You have to leave room in the groove for it to expand. The best result is when the depth and width of the groove perfectly fit the squished o-ring at a spec'd pressure as the parts come into contact.

So a few pointers for working in acrylic and making water blocks. 1. When you machine acrylic or poly, the surface will get "frosty" you can put the part through a process called "Flame polishing" that will give the part a mirror smooth finish. 2. When tapping with a bit like that, it's suggested that you try to get it as level as you can. To make it super easy you can take a drill press and insert the bit into the chuck and then spin the chuck by hand to tap the acrylic. 3. With an o ring like that you want about 1-2mm of the o-ring above the top of the c channel you cut. You may want to base this off your o-ring material though. Hope these help!

In industry we call more precise tolerances "high tolerance" which now that I think of it doesnt make total sense but yeah that's just how it is trust me I work on CAD every day. I think the reason it's like that is because the "high" in "high tolerance" is not referring to the amount of range that is accepted as a dimension, but is saying the tolerance has a high standard. Like it's an important tolerance.

[@Sketch1994]

Precision and tolerance are very often wrongfully interchanged by laymen around the globe...it gets worse when you add clearance and interference in the mix and waaaay worse when you add roughness, form deviation, true position etc etc...I really believe that using the right words in the right order is really important in this industry (my humble engineer/machinist opinion) to communicate the right result. I've seen engineers who couldn't grasp the concept of a high precision (low tolerance) clearance fit such these found in air bearings...

13:15 As an aircraft mechanic I can assure you that air transport is a hell of a lot safer than car transport. The level of planned maintenance on aircraft is probably only exceeded by rocket maintenance. In the aero transport business no-one is gonna ignore an check-engine-light for any amount of time, the groove depth of the tires are checked on a per flight basis. Same goes for oil level. On a side note, watching you guys using tools like thread-taps and such, gives me a nervous twitch. I just wanna slap those tools out your hands. For me watching these videos, is like others that like to watch horror movies, or go into haunted houses. Very uncomfortable, but afterwards I can just laugh at it. :)

[@lhl2500]

@omgwtf696969 Without further details your comparison is meaningless. What type of parts are you referring to? Quality control for different parts has different tests depending on material, operational conditions (temperature, pressure, environmental hazards etc.) So unless you are talking about manufacturing the EXACT same part, for two different industries, the comparison has no influence on my post.

[@TheWinning247]

Some mild difference between maintainance and design when it comes to aircraft, they are designed with very narrow safety margins because excess weight is an aircraft's achilles' heel, the difference between that and a car is that an aircraft is designed to "soft fail" so any failure that does occur is rarely critical and those components are designed to fail after a certain amount of time so that a technician can specifically look at them periodically to maintain the aircraft. Road vehicles on the other hand, are less designed for that mode of failure, as excess weight isn't a crippling factor in the function of the vehicle, instead they are designed to withstand certain stresses and not fail or show signs of failure; meaning that they are more likely to break in a pseudo-random fasion. I can almost guarantee that aeronautical parts are of higher quality than automotive parts, simply because the materials and tolerances are far more strict than in a road vehicle and the processes that produce them are controlled far better too. Quite simply; if a car fails, you don't drop from 36000ft at 2-300mph into the ground. Aircraft, however...

[@ProjectWolfDragon]

For machining copper, quality cutters and proper speeds and feeds help (look in the machinery's handbook) BUT the best thing you can do to help yourself out is material selection. Specifically, the general purpose Copper 110 alloy is terrible for machining, it is sticky, chewy, and overall unpleasant, whereas Copper 145 aka Tellurium Copper is the easiest alloy to machine and yields significantly better results. Other routes you can take is to use a free machining brass such as Brass 360, Aluminum 2011, and Aluminum 6020 as they are also excellent for machining but are also of significantly lower thermal conductivity than copper, so you would be forced to do very fancy details to get the surface area up to match a relatively simple pattern or even flat plate of copper.

[@b0ngitnator387]

I dunno what it means but Linus you better follow the tips.

[@markp8295]

Very good points. I also think a spindle speed reducer is needed to allow them to cut copper more cleanly. It looks like their turret is a cheaper high RPM only one for cutting wood and plastic.

[@another1commenter770]

Copper and aluminum.... Spray with wd40 or crc while cutting.....Make sure your taking deep cuts that throw chips/swarf even if the tool is very small it must cut enough to produce a decent swarf amount otherwise the tip will get to hot, the material will go buttery and bind to the tool. Don't try low feed rates unless you have very low spindle speeds. If a 1mm tool was to be used id start at 70,000 rpm at 700mm/min (100mm per 10000rpm @ 1mm tool diameter) for copper with occasional sprays of wd40 and constant air cooling. At 1mm tool tips the high speed can make the tool more rigid to deflection, just like how a dremil running at 30,000 rpm will steady a .5mm drill bit better then running at 500rpm. You can also get coatings for tools to reduce brazing of copper to tool like Chromium Nitride.

[@Cheesyxable]

they really need cooling and lubrication if they want something decent out of that copper with that machine, it might not be enough, but the result would improve for sure, and yeah coated tools as mentioned above

[@galaeron554]

Wd40 for aluminum and copper is a must. Lubricant is needed. Watching this from a machining career stand point it was cringy lol

[@mikes2381]

Guys. Machining copper, aluminum, brass, etc is all Very easy. How fast are you running your spindle? O ring grooves need +/- several thou for a good seal. You're not sealing N2 or He2 at 2000 psi. They're not necessarily all that sensitive to tolerance. One could probably use an engraving bit for the small channels on over the CPU. Man Linus. That tap is way crooked. Probably use a larger bit and a slower speed.

[@mikes2381]

Using CA glue on o-rings Is actually a good way to make orings. Mine seal a vacuum chamber very freaking well and a buddy worked at a place that made them seal in 10k psi hydraulic forming machines.

[@mikes2381]

Safety factor under 10%... *Cringe 1. That's not a factor. That's a percentage. 2. Plane S.F. are usually around 1.4 and up. That's commercial aircraft. So under the most demanding possibility hundreds of experienced engineers and over 100 years of flight can come up with; they multiply that stress by 1.4 and build to that. Then test... Extensively.

Your CNC router has plenty of spindle speed available to cut the copper, but the lack of coolant might be a large cause for issues. Even if you stand there and blow on it with compressed air, it would be better than nothing...but if you hook up a mist coolant system then it'd be even better.

Machining the acrylic flat, when acrylic easily is flat enough for the application. Using a clamp as a tap wrench, thereby putting a strange sideways torque on it, risking it getting oval-ish threads. (yes, this is a thing.) Gluing together an O-ring and being nearly 50% off. (this is a potential leak source, though a water cooling loop might not have enough pressure to make this a big issue.) Well, I have seen many horrors the last 20 minutes apparently.... Though, at least they greased up the O-ring, something that even larger operations don't do for far more expensive products.

[@robertvandeneijk1284]

I've machined acrylic more than a few times. Thickness can sometimes vary 2-3 mm over a meter length on a '8mm' thick sheet. I would have machined it too when the part is already on the CNC table. The glued o-ring is terrible. It may not leak immediate. But the pressure combined with deteriorating rubber will cause the bond to break eventually. Also, they should have tapped with a drill-press as bit holder. Then you're always straight.

[@GoldyMcGoldface]

The funny part is that the one compliment you gave them is still wrong, petroleum on o-rings is worse than not lubricating since it cause them to deteriorate.

[@todayonthebench]

@@GoldyMcGoldface If rubber/silicone O-rings deteriorated when in contact with petroleum/hydrocarbons, then all hydraulics equipment would start leaking fairly quickly after manufacturing. The main reason equipment starts leaking is due to physical wear and abrasion. Though yes, there are O-rings made of plastics. (and most plastics dissolve in oils/grease. (And it is from here the large misnomer about o-rings deteriorating in oils comes from.))

Indeed even small misalignment between the ends sounds like a terrible idea. If you have the ends plain loose or connected with some weak glue purely for placement purposes, it would just find its own alignment and may be most likely to seal perfectly fine among available techniques. Obviously CA glue is not your friend here, but if it works, it works 🤷

Yeah, anyone who has worked in an environment where prototyping/fabrication work is done will watch this video and die a little bit. Couple of thoughts to help with future iterations: -When tapping threaded features, it is really helpful to have a surface that is known to be level, and an axis that you know is "close" to perpendicular to it. If you put a punch or center in the chuck of a drill press, and use that to hold the end of the tap, you can ensure that the tap stays straight, and it will make it faster to do multiple holes. Also, cutting fluid is a godsend. -Well done with your use of the gasket fitment guide. As a recommendation, you could leak test your prototypes with compressed air at low pressure (50 kPag / 7.5 psig), and measure the leakdown time. Then if you detect a leak, you can locate where it is coming from with a little soapy water. The big flick here is that you are able to leak check you parts in a way the doesn't risk your expensive computer components that can't get wet. -if you do a bit of research on the fin design of your heat exchanger, you may get substantially better thermal performance.

top tip for tapping; mount the tap into a pillar drill to keep the tap straight only ever hand turn the bit when tapping though!, this is very important for acrylic where you can get fractures if you're not straight enough

[@Zilli_341]

Try to use an engraving bit to make a "grid" where the water makes contact with the copper, increasing the surface area. it's not going to be as effective as the fins, but it's better than nothing

I'm a little late on this one, but when you have to tap a hole use a drill press to hold the tap strait and the drill press table to hold the block flat. Now you just open the pulley cover so you can manually turn the tap. this way you get a perpendicular thread. You may need two people though.

Hey Linus, I am a mechanic and I have a Loctite brand O-ring Splicing Kit in my box and it comes with cords of various thickness Buna-N material and super glue and a razor to cut the cord. So yes, it is an acceptable method of repairing, or making new o rings in the field and you can actually use many small sections to make one big o ring if you wanted to. Hope this helps. Id recommend getting one if you want to do more custom stuff in the future. P.S. you can only use them for static loads, not dynamic loads.

[@JuxZeil]

OUCH!! A few pointers; When tapping a thread or machining acylic, use a grease or Vaseline on the cutting tool. When finishing Perspex, acrylic or poly-carbonate, sand all the way to 2000 grit and then heatgun at 150C approx 1/2 foot away. Always leak test powering only the pump(I'm sure you're just baiting here). You can make channels in the cold plate using a rotary cutting disc(not grinding, too thick). May not be up to EKW standards, but it does help with temps. Great vid, follow-up soon? ^__^

[@sasjadevries]

If you have some skill then you could make the tiny slits in the copper with a dremel and a cutoff disk. If you don't have any skill whatsoever then you can clamp the dremel down to a table, put the block into a vise and slowly feed it towards the cutoff disk and still get it done. If you even manage to let that fail then you work at LMG. When cutting by hand you can compensate lack of skill by guideblocks, securing things down and jigging things up. Btw, if you want your block to be flat you're better of flattening it by hand, your routerbit isn't flat and leaves machining marks. You can just learn the technique of metalscraping from Igor Negoda and get to sub-micron precisi..... Ehm, I mean just get a piece of glass or a mirror and put fine grit sandpaper on top of it and use it as a sanding-block to get it flat enough.

[@Retanaru]

I died of laughter when he floated the idea of using a tiny bit instead of a cutting wheel to make the fins. You can even see they used a cutting wheel on the fins for the block they compared it to. Keep things simple boys.

[@PrismofScience]

Excited by the presence of Alex.

[@nothanks9205]

just drilling a bunch of tiny pits in the waterblock surface just under the inlet and making the block more restrictive will greatly improve the performance. Pumps create flow resistance creates pressure and pressure is what cools.

[@scarffoxandfriends9401]

pro tip Linus, let's say it's a scarf prototyping tip, you could test the water flow for leaks separate from the finished components. That way if there was leaks it wouldn't destroy your mother board =b if you where planning to use the four extra screws attaching it to the mother board as extra pressure to prevent leaking, you could have screwed it into a thin wood or metal sheet.

You're using the wrong adhesive to bond an ELASTOMER. You should use Loctite 480, NOT 454. 480 has microscopic black rubber spheres in the formulation which add flexibility when bonding elastomeric materials. It takes a little longer to polymerize and is thicker, which makes it easier to use too (it's also the right colour). I didn't notice an "adhesive scientist" in your recent jobs promo vid.
