I was so excited to see this video. Please dont end the series. If it runs i would love to see a forced induction. Just for the love and fun of it. You have done so well
Glad to hear you like it and if I come up with some interesting updates it may be more. But right now my head is empty and a lot of projects concerning the heating system of my house. It must be ready for next winter.
You can make a stylish cover for the expansion tank by molding a fiberglass "hood scoop" over both the tank and the air filter. It will both hide the tank from sight, while giving it the appearance that it was intentionally form-fit into the system from a factory. If you make a one piece 'flip-forward' hood assembly you can check the coolant at the same time as the air filter and it will seem to be 'all part of the master design'.
Just one small detail, remember - if the system was not bled properly and/or overheats, not only your face is on the line of fire, but also, your carb and you could flood the engine with coolant.
As a mechanical engineer, I have to say a nice project with good implementation 👍🏻 Keep it up I'm curious to see how it runs, maybe balance the crankshaft with master weights 😃
Its a shame to think this build is concluding 😭 Maybe its a good time for you to go lawnmower racing ??? Im sure you'd Clean Up !!!!🤗😉😎 Love from New Zealand
If your next video will be your last, thank you very much for all you've shared!! If you change your mind in the future, I'll definitely watch no matter the project.
im excited to see where this goes. this is an aesome series, but a lot like things in life, some stuff has to end at some point. thank you for all of your content. its inspired me a lot.
Those parallel scoring lines in the threaded nipple are going to produce the potential of a leak in the cooling. I've had to re-seal people's plumbing before from this. Its a simple fix, though, thankfully. Just take some emery cloth and sand the ridges out of the pipe to ensure no grooved passages for water to escape and leak through.
Hope this is not the last we ser from you, i still want you to make videos when you feel like doing them, i love your content because it is not forced it is simply a briiliant guy in his garage tinkering a beast to life. Please keep us updated with the future of this channel in the next video. Like from Iceland :)
Gday, absolutely brilliant work, I’m confident in saying that the next video won’t end in tears, I believe the engine will run like a dream mate and I can’t wait to see it running, awesome job mate, cheers
Hello Matty, you are an amazing machinist as well 🌠 I love your channel and so happy to see you're doing well❣ I live on Vancouver Island British Columbia [world capital of bathtub racing] I have learned a lot from watching your videos! Karen and Curtis mentioned your channel thankfully😊 I think you should do a mini v8 as well 🏁
What oil painting technique uses layer, after layer, of applied colors and brush strokes, to achieve the desired look and function one wants....ask Rembrandt......Whatever, you are killing it.
love your videos, as always i get so excited when i see you have made new ones, i was surprised to learn that linseed oil can be used as a finish for steel, i must try this some time. i almost felt heartbroken to hear you say the next video will be the last in this series, however, i love all that you do and i cant wait to see what else you are getting up to. keep up the good work
Yes, linseed oil is fantastic. (boiled) . If you treat a piece of iron and leave it outdoors it will not rust for years. And you don't have to clean the pieces before. When you seel pipes with tapered threads the the flax and the oil grinds to a paste , then you can come back ten years after and move the pipe and it still holds water.
Please make another intake manifold with more volume. The end cylinders might be starved for aif/fuel mixture and run lean. Of course you can validate this by measuring exhaust temperature, but I believe the end cylinders will be hotter the the middle cylinders.
As ugly as you may find the expansion tank, I think it'll grow on you. for the low budget put into this, I think it's pretty nice looking all things considered. There are those of us out in the audience that aren't familiar with the mixture of plumber's flux and linseed oil + hemp twine for use as thread sealant. This is the first time I'm hearing about something like this at least and I've never ever seen that done with older cast-iron piping here in the states, so it sounds like a regional old-fashioned trick... or I could be very wrong. I had to google it up to find out this is a normal thing still in many parts of the world... pretty wild! Since you're mixing cast-iron and aluminum it may be pertinent to add a just-in-case anti-corrosive agent to the coolant long-term for mixed metal reaction reasons. If this ends up working as designed however, this project should get all the attention. I've been watching since the Hackaday article of your earlier activities with this engine when it was air-cooled, and now looking at it, I wonder if such an engine could be fitted into an older, simpler (think:1960s) economy car as the power plant instead of whatever engine it has. We're all over here watching you forge engine pieces like it's nothing, and absolutely awestruck in what you've achieved. As much as I'm assuming you'd be against the attention as this is a hobby project, if this ends up working, I wonder how long it'll be until Briggs&Stratton are calling you up for a media spot. this and your rotary lawnmower are two very special pieces of mechanical engineering in their own right and I do wish more people could see these videos.
Excellent work mate, i am absolutely delighted that you got that pump! You have done a lot since your last video, do you allow people to write to you like a fan mail? Id love to send you something that i think youll enjoy and understand. Anyhow excellent work, the beast will live!
The lawnmower was disposed on my front drivway by a friend. So it was a coincident that the engine ended up there. It was most because it's nice to be able to move around the engine in the garage.
Väldigt synd att du slutar filma dina projekt. Jag gillar att se dina videos och det gör nog många andra med. Jag förstår att det tar en massa tid för att du har väldigt bra filmade och editerade videon. Kanske lite enklare videon som inte behöver klippas och redigeras vore nåt?? Tittarna finns nog kvar även om det inte uppfyller din suveräna klass och standard.😊
When it comes to steel water pipes we still use inches. But they are fading away. Everybody use copper pipes these days ( or plastic, God forbid) and they are in mm.
Have you pressure tested your heads? I worry they're going to leak because you machined the gasket mating surfaces in multiple passes, which may have left a ridge and also because machining large, relatively thin pieces like that can often introduce warping. Did you check them for flatness?
I have put 5 psi in the complete cylinder/head units and the pressure falls very slowly. I think the problem is between the cylinders. I will mix my coolant with a little "Bars Leaks" just in case.
