How To Measure: Simplifying Complex Bends With Hard Tubing - PC Water Cooling

- I discuss how to measure, simplifying complex bends with hard tubing runs when water cooling PCs. My process and technique is just that, what I use. You may use a different process and that is okay! I'd love to hear what your process is in the comments below. This process will save you money by replacing fittings with bends and also elevates the aesthetics of any run (unless you are going for the fitting look in the middle of the run). Enjoy!

Hi! Just droping huge thank you! I'm doing a custom loop for the first time and holy this video was so helpful. Before I was using specialty tools because I thought that's the only way I can get clean bends. Turns out freaking hands and a ruler give literally the same result. With bending tools I already crewed my 4 bend tube three times. With your method I had done it the first time. THANKS
I’m really happy to hear the video was able to help! I also went through that same struggle and found it easier to free hand it with a ruler!
Great technique for Beginner's. Great video.
Thanks for watching!
insert a wetted, Si mandrel into the tube BEFORE you heat/bend the tube. your technique alters (“squares”) the outer radius of the bend section, resulting in a kinked section. results in a pressure increase and flow restriction. not super important at these H2O pressures and Q (flow rate); however, the pressure increase become significant as the number of bends increases. essentially, momentum and Q changes in your system. look into EKWB bending blocks (acetal matl) for best practices.
Do you have a link to the mandrel you are speaking of to insert into the tube? I use a silicone core to prevent deforming, but if there is something better I am all for it!
^ sorry. if you used a Si insert then your 90deg bends would be cleaner. look up tools offered by EKWB
@@kenw8875 will do! Thanks for the information!!
The black piecekf stuff inside his tube when he bends it is a mandrel, he's just calling it a different thing. They are both silicone pieces that slide inside the tube to allow internal support for bending 😊
I was.confuswd during the whole video. Still don't know how to measure a 2nd bend.
Would love to try to help you! What would you like me to try to break down further?
I'm not sure if you have this information but this appears be similar. Where 1/2 inch electrical conduit is concerned, inorder to make a 90° bend, you have to add 6 inches from the total length desired and make the bend from that point. Meaning that if you need a 36 inch run of electrical conduit with a ninety degree bend at that 36 inch mark, you would add 6 inches from the desired length and begin the bend at this extended point. This is because the curve of the 90° bend takes up the 6 inch slack, and you ultimately end up with a 36 inch 90° bend. I assume the same is true for bending acrylic cooling pipe. However, the takeup slack must be a different length. Do you happen to know what that is? This would be helpful instead of trying to make estimations based on static measurements, you could simply add the required length to accommodate for the desired bend.
I did not previously know that about electrical conduit, but I, unfortunately, do not know what the take up slack would be for the tubing would be. I think that take up slack would also require the bend to be the exact same radius on every bend as well so you would definitely have to use a mandrel bend tool to ensure you are bending the same radius every time vs doing it free hand. If you had the same bend radius and the correct take up slack amount I’m sure it would translate to accurate and easier measurements! One problem I could see arising is some of the bends had to be tighter than others in my build so I wasn’t able to use a specific mandrel tool for every bend, so that style measuring could have worked for some of the bends but not others. Thank you for the information! I may try to see if I can plan a build’s tubing to be able to have all the same bend radiuses so I can use this technique.
@@techtoniksystems Thank you for the reply! I would definitely like to see a video of you applying this method because I'm super curious. If you do a CZcams search for 1/2 electrical conduit at 90°, there is a plethora of videos that show you the technique I was trying to describe. You would be correct about different radiuses. In the electrical field, there is a special bending tool used for specific conduit that has markings and tells you where to lineup the tool so that you get the exact bend you're looking for. It's too bad there isn't a small version of this tool for PC pipe bending. I subscribed and look forward to your next video.
Thank you for subscribing! I do want to revisit this topic so thank you for providing this info for me to look into! I hope you enjoy my future videos!!
Alphacool and EKWB both have different versions of a bending tool. Alphacool's is the closest in design to the EMT benders @Sartre_Existentialist mentioned, while EKWB's is more of a plate with 45 and 90 curved grooves for setting the heated tube into. I have the Alphacool one and it works ok, but I find it easier to use a wood jig with 45 and 90 corners to set the heated tube against. To get specific lengths you can just clamp a bit of wood or whatever as a stopper to set the end of the tube against. As for the same consistent accuracy as EMT bending, I think even with the tool you have to be consistent with how you heat the tube, too. EMT you do cold, so it's not a concern though EMT conduit does sometimes kink if you are not careful.
@@raggarex Heat consistency is definitely one of the most important parts for sure! That is probably where I had the most problems when I first started bending tubing. Too cool and the tube will flatten and balloon a bit on the sides of the bend, too hot and you can easily twist/discolor/burn it!
You can explain this much much easier and also recopmend bending form tools that have arrow markings making precise measurement much eaier and makes bends perfect. Also to anyone: use sharpiea to mark your mrasurements and just wipe it off with alcohol after it wipes right off
I’ll have to retry the sharpie because, when I tried that, it melted into the tubing and did not come out!
Are you heating the tubes on the table?
I am using a heat gun that sits vertically on the table, and I am holding the tubes over the heat gun! I move the tube to the ruler which is on the table to check the bend and then back to over top of heat gun to make any adjustments
I think I’m gonna try to bend mine on the table with the heat gun down blowing down on the table. I can’t get this man I’m having a lot of trouble. Bending . The tubes in the air is working horribly for me.
@@Bertis87 what part is going bad for you? Maybe I can help you figure out what may be going wrong. It is a fairly difficult process at the beginning so give yourself some grace! The only thing I would be concerned about is potentially fire hazard/burning the surface, but if you are working on a surface that is safe for that, it’s worth a shot!
Why not marking the middle of the 90° bend and use a bending tool? 🤔
I haven’t found a way to mark that doesn’t leave permanent damage to the tube, but if you know of something that doesn’t I’d love to know! I also like tighter bends than the bending tool I have is capable of doing but you definitely could use a bending tool.
I highly reccomend marking tubing with sharpie and using bending tools it mskes it much less complicated
Use a sharpie. Wipes off with alcohol
@@techtoniksystemsbending tube that goes into the pipe ur bending with a mark on it
Should have watched that before fucking up two tubes
Don’t worry I still mess up tubing plenty 😂 it’s inevitable!
that is not how bend tubes
Thanks for watching!
