1 00:00:00,00 --> 00:00:01,500 Hey guys, Welcome back. 2 00:00:01,600 --> 00:00:04,500 Today we're going to be building a minature steam engine kit, 3 00:00:04,600 --> 00:00:07,000 and simulating it using C++. 4 00:00:07,500 --> 00:00:11,100 I challanged myself to finish the entire project in one week. 5 00:00:11,200 --> 00:00:16,000 So it should be a pretty wild ride, and I think you'll like the result 6 00:00:16,100 --> 00:00:20,900 I'd like to thank Rena, our first ever Patron at the "Master Mechanic" tier for their support. 7 00:00:21,000 --> 00:00:26,700 And a special thanks also to Squarespace for sponsoring this video, and making it possible. 8 00:00:26,800 --> 00:00:31,600 If you need a comprehensive tool to set up your website, Squarespace is an amazing option. 9 00:00:31,700 --> 00:00:34,000 More about them later. 10 00:00:34,100 --> 00:00:37,500 [DAY 1] [THE REAL ENGINE] 11 00:00:41,000 --> 00:00:45,500 This thing has been sitting around my apartment for months now and its finally time to open it. 12 00:00:46,000 --> 00:00:51,000 Sterlingkit sent me this engine to review, and I wasn't really sure what to do with it 13 00:00:51,100 --> 00:00:54,000 Since I don't really do unboxing videos on my channel. 14 00:00:58,000 --> 00:01:03,000 Now that all the packaging is gone, we can start going through all the pieces. 15 00:01:03,500 --> 00:01:08,500 The build quality is actually pretty decent, and they did include all of the tools that 16 00:01:08,600 --> 00:01:13,300 you need to build it which is good because I don't have any tools at my current location. 17 00:01:19,000 --> 00:01:22,400 The first step is to add these rubber feet to the bottom of the base. 18 00:01:22,500 --> 00:01:27,800 Now trust me, when this bad boy gets going, it's going to need these heavy duty motor mounts. 19 00:01:27,900 --> 00:01:33,800 Next we connect the piston to the connecting rod with a very very small wrist pin. 20 00:01:36,500 --> 00:01:41,100 Then we need to connect this cylinder sleeve to what I'm calling the cylinder head. 21 00:01:41,200 --> 00:01:47,800 There is a small o-ring that goes here, and I used the wrong one But I fixed it off camera, so don't worry. 22 00:01:47,900 --> 00:01:52,700 The sleeve is attached with this plate and four screws. 23 00:01:58,200 --> 00:02:03,400 We can now put the piston into the cylinder through the bottom and slide the valve into it's bore 24 00:02:03,500 --> 00:02:05,000 in the side of the cylinder head. 25 00:02:05,100 --> 00:02:10,500 The entire crankshaft and valve linkage comes pre-assembled with the kit. 26 00:02:14,000 --> 00:02:18,500 Now we can attach this plate which holds everything together. 27 00:02:23,200 --> 00:02:29,000 Once that's on, we attach the two engine mounts which will be bolted to the base later. 28 00:02:30,800 --> 00:02:36,200 The flywheel is then attached onto the crankshaft and secured with a set screw. 29 00:02:36,700 --> 00:02:40,800 The entire assembly is held onto the base using two screws which go through the 30 00:02:40,900 --> 00:02:43,300 engine mounts that we attached earlier. 31 00:02:44,800 --> 00:02:49,500 And now we can attach the frame to the cylinder and engine mounts in the same way 32 00:02:49,600 --> 00:02:51,200 as the other side. 33 00:02:57,000 --> 00:03:00,500 The manufacturer includes a pulley for the opposite side of the crankshaft which 34 00:03:00,600 --> 00:03:05,400 I guess you can use to drive a load of some kind. This attached the same way as the 35 00:03:05,500 --> 00:03:08,000 flywheel with a small set screw. 36 00:03:09,000 --> 00:03:15,700 Now lets move onto the boiler. After putting the orange o-ring in the correct place, we can attach 37 00:03:15,800 --> 00:03:17,500 the outlet to the top of the tank. 38 00:03:18,000 --> 00:03:24,500 The two halves of the tank are held together with 12 screws around the perimeter, and three of those 39 00:03:24,600 --> 00:03:29,000 screws are actually special, and they work as studs to attach the three legs that hold the boiler 40 00:03:29,100 --> 00:03:33,900 above the base of the engine. 41 00:03:36,000 --> 00:03:38,800 Three screws then hold the legs to the base. 42 00:03:41,400 --> 00:03:46,000 Once we attach this hose and the blow-off valve, we're done. 43 00:03:53,000 --> 00:03:54,000 (He also attaches a tiny little chimney) (SO CUTE) 44 00:03:56,000 --> 00:04:01,000 After filling the engine (boiler) with distilled water, we can add fuel to the cup under the boiler. 45 00:04:01,700 --> 00:04:06,700 You should use denatured alcohol for this, and not isopropyl alcohol like I am. 46 00:04:06,800 --> 00:04:11,600 I didn't really have any and this was the best I could do given my time constraints. 47 00:04:11,700 --> 00:04:16,500 Isopropyl alcohol has a very sooty flame which you can see in the video. 48 00:04:16,600 --> 00:04:21,000 You probably also don't want to run this indoors on a flammable surface which is also exactly 49 00:04:21,100 --> 00:04:24,800 what I'm doing. Now trust me, I know a thing or two about freak accidents okay? 50 00:04:24,900 --> 00:04:30,500 This is me almost getting Jay Lenoed while I was trying to film footage for my first Engine Simulator video. 51 00:04:31,000 --> 00:04:36,200 Anyway, I wanted to try running this engine longer but decided to wait until I had the right fuel and 52 00:04:36,300 --> 00:04:38,500 a better environment to test it in. 53 00:04:39,000 --> 00:04:44,000 While it was running though, it was extremely cool and it worked surprisingly well. 54 00:04:57,000 --> 00:05:01,800 I think I'm more suited to operating a keyboard, so let's move over to the computer and start 55 00:05:01,900 --> 00:05:05,900 writing the simulation. Now you might think that I opened VS Code and started doing some 56 00:05:06,000 --> 00:05:11,800 really cool prototyping or something but no, I like to start with the art personally. 57 00:05:11,900 --> 00:05:17,200 Now i know it seems a little backwards but I think that all the parts of a project are intrinsically linked 58 00:05:17,300 --> 00:05:24,000 and kind of guide each other. It's kind of like how some games have their soundtrack written before the game. 59 00:05:24,500 --> 00:05:30,500 Anyway, I started visualizing the program in Blender and seeing what problems might come up in the development. 60 00:05:30,600 --> 00:05:35,000 These assets are all temporary but they can be cleaned up later. 61 00:05:35,100 --> 00:05:40,500 After a few hours, I had 2D models for all of the important components of the engine, and this is 62 00:05:40,600 --> 00:05:45,000 enough to get started with the programming, and it's a good place to end day one. 63 00:05:46,600 --> 00:05:54,400 As some of you know, I recently quit my full-time job at Google to work on YouTube and Engine Simulator full-time. 64 00:05:54,500 --> 00:05:59,400 It's been a really interesting experience starting my own business and managing an online brand, 65 00:05:59,500 --> 00:06:06,000 and that's where today's sponsor, Squarespace comes in. Squarespace is a comprehensive website building and 66 00:06:06,100 --> 00:06:10,900 hosting tool that has a lot of features that are perfectly suited to online creators like myself. 67 00:06:11,000 --> 00:06:16,900 I'm actually building my company's website with Squarespace and they offer a wide array of analytics to help you 68 00:06:17,000 --> 00:06:23,000 adjust your site to your target audience. They also offer a member areas feature, which is great for 69 00:06:23,100 --> 00:06:29,000 my current model, which relies on online supporters. It also integrates easily with my other social media.
