Happy new year also and your wife is so nice to allow you to use the stove for aging the heads. Thank you for showing all of the steps (casting, machining, etc.) I really like all of the details!
@@sparraAus I second that. The dishwasher does make for an excellent parts washer. I got a free dishwasher from the local classifieds and did exactly that.
By adding fins to the top, it would use both styles to cool the engine. Similar, rougher texture inside the water jacket would also transfer more heat. Heat transfer is all about maximizing the surface area while keeping the fluid flow over the surface area laminar.
Gday, absolutely beautiful job, certainly a lot of work involved but it’s definitely going to be worth it, have a great new years and thanks for all the great content this year, cheers
Happy new year to you as well! Keep up the good work! An electric water pump will work just fine, also add a thermostat to the system, pressure cap and look into Spal thermostaticaly controlled cooling fans, with variable rpm. They offer great temperature control.
I'm not planning to use a conventional thermostat. The radiator I have found have an electrical fan with an electric thermostat. I hope it will do the job.
You might want to consider going back in the water passages, all those squared areas should be rounded off. Any sharp angular areas like that will cause cavitation problems and that not only alters flow characteristics, but will create both hot spots and the cavitation will literally eat away the metal in short order. Just a thought.
Thank you. Unfortunately the weather has been windy, snowy and cold lately so outdoor casting is out of the question. Hoping for improvement next week...
Absolutely Fabulous, ive just recently found your channel, and im thoroughly impressed, i love home workshop engineering, tho you're obviously highly skilled, i was curious how youd water cool solid aluminium heads.
So... I'm a bit perplexed. I assume you're converting to water cooling due to a cooling deficiency... either completely (low throughput), or under sustained load (low capacity/duty cycle). Much of this could be solved by reversing the position of the valvetrain to the valley side, and having central intake/exhaust like the 1st generation Cadillac V8. It would eliminate the cylinder crowding of the intake passages, and limit exhaust temp absorbtion. It would also allow you to simplify the cam/timing assembly to a single cam.
At the start of the project the goal was to make an engine out of Briggs & Stratton lawnmower cylinders. That is why the valves and cams are were they are. It is much easyer to do like Ford and everyone else but for me I must make a new crankcase and that is to much work. And with the valve train to the valley side the exhausts goes thru the waterjacket with coolingproblems. I have the intake manifold thru the waterjacket instead. I just wanted to convert the engine to watercooling in a way that looked possible with the tools available. And mostly in a way I felt fun.
This Is an awesome series. Have you considered trying a cross-plane crankshaft in place of the flat plane? I’ve thought that would give it a cool muscle car sound
Yes I have. When I made the crankshaft I knew very little about V8 crankshafts. I made a flatplane because I is easyer to balance. But yes, later I understood that if you want that nice sound it should be a crossplane. But it's made of a expensive piece of steel with a weight of 19kg. When I was finished it was 5,5kg. I'm not doing that again...
8 hours in 200 dgr C. I read somewhere that it should be treated 8 - 30 hours in 180 - 200 dgr C. It was a big improvement compared to when I did nothing. Fresh casted aluminium gets a bit spongy and sticks to the tools during mashining. It hardens gradually and after a month It should be hard. But you can speed up the process with heat. But I'm no expert.
Looking really good! I'm worried there will be coolant leaks around the spark plug holes. The sealing surface looks kinda thin and no fasteners near them.
Se det positivt, tog ju bara 3 månader att både designa och tillverka hälften. Nu behöver du inte designa något, samt att du redan vet vad du håller på med, så det borde väl inte vara mycket mer än 2 månader :)
Kanonvideo som alltid! Mycket kul att se och lärorikt. Vad är fördelen med att gå med liten fräs först och sen den stora mot att bara ta den stora? En sk. Flycutter, skulle den göra jobbet bra? Den går väl att få till att ta hela bredden?
Jag har en lite klen fräsmaskin. Den stora planfräsen tar kanske 0,2mm i varje skär men ger en väldigt fin yta. Den lilla fräsen tar ett par mm och skulle jag hitta lite lös sand från gjutningen så blir den slö, men kan slipas om. Den stora fräsen har vändbara plattor som kostar skjortan. Jag tar väldigt små skär för att ju grövre skär du tar måste arbetsstycket sitta hårdare fast. En ny gjuten bit deformeras lätt om man spänner för hårt. Så jag har gott om tid och tar små skär och slipper gjuta om. Har aldrig provat en flycutter men den har väl bara ett skär så matningen måste bli väldigt långsam och jag tror inte man tar mer än högst 1/10 mm varje skär. Men det blir en plan och bred yta. Tror inte min lille maskin klarar det.
Kanske inte för att jag kan, men för att ta reda på om man kan. Lite nervöst att hänga ut hela projektet här och kanske misslyckas för öppen ridå, men så får det bli. Mycke kan gå fel...
@@Desmouffe Alltså, du är på en sådan nivå att även om detta nu skulle gå käppers - så är det fortfarande så otroligt coolt att du/någon prövat. Och om det lyckas. Wow. Så i princip kan det här bara bli bra. Alldeles oavsett hur det går. I mitt tycke. Jag själv skulle inte komma på tanken att pröva mig på detta. Har inte maskinerna, skulle inte veta hur man använder dem, kan inte tillräckligt om material, jobbar inte med CAD, har inte ögat för lösningar och skulle inte ha tid. Men jag får följa dig! Stort tack för det.
@Desmouffe , mine is too. But, she would still object to me using her kitchen oven to do any curing, aging, or heat treating of any metallic devices. Food and proper cooking dishes is all she wants in her oven.
