It's really a shame that people don't appreciate stuff like this, or the people who are able to do stuff themselves, who have the knowledge and skill to *truly* make stuff.
Gear head nirvana. Knocked over with your work. That casting looked so clean it seemed almost seemed ready to use ;o) I was dazzled and amazed. Is there nothing you can't do? I don't normally enjoy background music but your choice was near cathartic. Add slow motion and it would be a religious experience. Thanks so much for sharing. Cheers.
The Yamaha YZ/ TZ engines are legendary... Is it that hard to find used parts now that you are casting crankcases? Then what do you do for heads? Cast them also?
Only if it's a heat treatable alloy. And yes the casting is MUCH stronger and easier to machine when heat treated. These cases are CC601 or you could use LM25.
that is really awesome what you did. I've always wanted to try casting. what is the advantage of casting then machining instead of simply machining from a big block of material?
Initial and material costs. Designing and programming to machine from billet(solid) would be very expensive. Copying and casting for the basic shape might reduce outlay 75% (?).
You could probably make alot of $ making 1985-89 Honda 250r atv left side cases chain side as there are alot of bad cases out there and the Honda 3 and 4 wheelers are still popular
Only if i had skills like yours and machines i would not be worried of phased out parts like here in philippines thats why our motorcycle has only life span of 10 years
@@sparkimoto there's a lot of parts needed specially some 2 stroke engines parts and some vintage 4 strokes. If you can provide the needed parts then a big business will be in front of you right away.
Well done for allowing this old stuff to live.
Original manufactures and parts suppliers should just give it up

Great video with simple instructions and no BS - thanks guys, this has taught me a lot.
That is damned pretty for sand casting. Makes me want to build a crucible and start making little buzzy multi cylinder engines.
while making the mold how do you adjust for the shrinking?
3% is added to the mold
Amazing work. Is there any place on the WWW where i can go and se some more of this project?
I really like your crucible caddy, have hurt my back in the past manually pouring castings...!

Cost
YZ490's are also a fuckin blast to ride!!!!
I have to say that it brought tears to my eyes.
Whitch Temp must the melted iron be to pour it into the moulds?
It's not iron, dumbfuck, motorcycle crankcases are aluminum...
Александр Перчов take it easy man. Harleys used to be iron. Aluminum melts around 1200°f, pour at 1400
What are you degassing with? Nitrogen?
Круто, молодцы! Жду с нетерпением новые видео по этому двигателю!
Coolest foundry I've seen on YT.
Nice job ,masters in their trade
Is this a PURE aluminium or ALLOY of it. If it is alloy then please describe which is it and how to make it
This is not pure Al it is lm25 which is a mixture of metals and such.
Best think to use is metal that has previously been cast I.e car wheels.
any body please. Do i have to heat treat this aluminum after casting? and how is heat treatment of Aluminum is done?
Tesfaye Dejen
Yes.
Depends. I've made hundreds of motorcycle parts without heat treating. Heat treating of aluminum wasn't common until the 40's.
this is pure gold. thank you

Very nice.Thank you.
Works of art. Nearly surgical. Next thing to magic
Wow lovely video! Thanks
Hey Uniflow, how is progress on this motor?
Wow. Good work.
Why do I see two guys wearing shorts???
Parce qu il ny a pas de Femmes!!!

Is there a big demand for such cycle parts in the PI? Any in particular?

I need some crankcase can we chat? ±2348063576207
I am having to cast my engine for 500 GREEVES crank case barrel and head made my own foundry had to have a crucible made in china 10kg of wet alloy
What did that cost you to order the crucible from China? If you don't mind my asking.
sparkimoto Sat foundry Alibaba cost £260 to the door
This guy is way too good of a machinist to be working so unsafely. I don't get it.
i am sure he has done this before
If you have cnc mill why not just make billet. No casting to do.
Alloy billet is far too expencive, here in NZ.
very cool!
ffin cool, great skill interesting
