  • In this video I show you all the steps you need to cast PU (polyurethane) rubber in almost any shape you want. For my tank track skateboard I needed rubber blocks for the tracks. I couldn’t find something that would fit so I decided to make my own..

      All these people are right. Adding a note in the title saying the actual language this is in is the expectation. Usually any non English video has a title in its own language or if not at least mention the language in brackets. If too lazy to to do so, I would explain people to complain about it, for good reasons.

    It's a bit late, but you should really vent or use gas masks with the right filter. Isocyanates are nasty for your lungs ;) and this resin (as most flexible PU's) catalyse with amines, which are also nasty for your lungs

    How good does it bind to itself? Could I pour multiple layers in the form to make a hollow object? I want to make a safe breecher tool for airsoft but think when I pour the head as one solid piece it would get quit heavy. So my idea was to pour bit by bit in the mold until I have a thick enough shell and fill it then with self expanding foam.

    I want to put a 5mm coating on some 40mm diameter bearings that are 12mm thick. for a final bearing diameter of 50mm. How do I prevent the polyurethane from seepign into the bearing races and destroying the bearing? is there a special type of tape or glue for that? Some company quoted me over $2000 to put a 5mm coating on some 40mm outer diameter bearings, but I want to save money and do it myself.

    excellent video, great idea to cnc the mould, other option is to make a mould out of silicone, no release needed, only one comment when using PU you must use a resperator with the equivelant filter to an 3M ABEK1, PU vapour is really bad for you, you can become highly allergic to it, two of my friends became like this, one was hospitalised the other the blood vesels in his eyes burst every time he is near PU

    What keeps the screws on the sides of the tracks, the ones that hold the links together, from being screwed down too far and binding the tracks, or from backing off and coming out? Are you just putting permanent thread lock on them and screwing them to the right depth or something?

      @@mofoq just checked the subs in a few random spots in the video and yes, they do seem accurate in my opinion, definitely not auto generated, they have some "Dutch feel" to them, as in, you can tell it's translated, but not by a machine. Also, yes, we do borrow a lot of English words, this is something I find interesting especially if you compare it to something like German. They translate and/or Dub (not sub!) everything. In the Netherlands, shows (except kids shows) will be shown in their original language with Dutch subs.

      Rowan is right about both things. The reason I switched is because I can better express myself in my mother tongue (Dutch) and thus enjoy the build process more. It was a though decision since I know the amount of international viewers who watch my content. I'm looking to make a second channel in english but I need to figure out the best way to do so.

      And, as it happens, modern 'Dutch' & modern English come from the same linguistic roots. The nearest to this origin now is West Fresian. Only old (Viking) 0:53 Swedish/Norwegian & the indigenous Brithonic, & Gaelic, dialects that were pushed out to the marginal regions didn't have this origin.
