@ 52 I;m JUST about to buy my Mini. I had promised myself another Mini Later on in Life. I learned my 1st Trade on Minis so now there are better Technologies/Materials and ECUs/Fuel Injection/ No faffing about with Points etc, I HAVE to Build a NICE FAST-ROAD Mini [But ClubMan front=more room]. Also SC Super-Charger kit will be ACE.
First class video, more info on the engine types you are catering for would be good, and in what capacities are they superior to the original manufacturers product? More please.
For production car forged cranks we'd agree, for lower volume aftermarket crankshafts there's no real advantage over billet. With billet we can regularly change and improve the design, and they're more than strong enough for the application.
Neil, the billet is EN 40b. It goes through a nitriding heat treatment near the end of production and this process toughens and de-stresses the material.
Billet crankshafts are better suited to low-volume production than forged crankshafts, as it does not require a new forging tool each time the design is updated and improved.
@@MEDEngineeringTechVideos thanks, so purely cost. My basic knowledge of metals tells me forged is much stronger. I assume the heat treatment will improve the structure.
@@andrewromans1967 It's mainly down to them being adaptable - with a forging tool you're fixed to that one design. Yes forging is in theory stronger due to the grain structure, however, this is only really applicable to the advanced forging tools employed by the household name manufacturers in production car engines, not necessarily aftermarket forgings. For us, billet is best.
Curious how come the chip-lets of the steel crankshaft is coming off like it's titanium? Curious when will part 2 come out? I love these how it's made series.... Not much will tell how they make their mechanical components... I like how you guys will though. :D

Great video.
This also shows why the crank is priced at what it is.
My dad used to make us make crankshafts with a hand grinder, file and a caliper.
Utterly fascinating
Probably the best video on the topic i've seen so far. Good balance between chat and show. Thanks
Interesting video!
I am looking forward to part 2 :)
I didn't know a billet crankshaft needed such a wide variety of machining procedures. Thanks for the video.
It’s amazing to me how those cutting tools go through billet steel like warm butter.
awaiting part two.
So excited

nice job, please upload the part 2 of crankshaft making. thanks!
Good point, we need to get Stuart back for part 2....
@@MEDEngineeringTechVideos yes, yes you do
@@gereblex5140 Stuart is at Red Bull Racing now!
How difficult would it be to juggle the CNC numbers and produce custom stroke cranks ?
It would need a re-design on the drawing and a minimum batch of 25 going through the shop.
First class video, more info on the engine types you are catering for would be good, and in what capacities are they superior to the original manufacturers product? More please.
We just specialise in the BMC A-Series engine ourselves.
I had almost forgotten how weird Mazak programming is. I'll stick with my Fadal, thanks. Cool video, we just don't much care for Mazak around here.
Is there only one type off BILLET steel for crank shafts, can you let me know please.
Incredible work! But where is part 2? I;m on the edge of my seat! :)
Are you trying to say nitriding or night riding?
Hi what cutter do you use? My father has a lathe and says that you can’t machine crankshafts they have to be cast
How much does it cost to design and manufacture a crank shaft
Where is part 2?
why not get the thing forged and have it bullet proof, not withstanding arrow's excellent abilities ??
For production car forged cranks we'd agree, for lower volume aftermarket crankshafts there's no real advantage over billet. With billet we can regularly change and improve the design, and they're more than strong enough for the application.
Where's part 2? loved part 1.
I can’t find it either…
Where is part 2
With all that machining does it not need stress relieved?
Neil, the billet is EN 40b. It goes through a nitriding heat treatment near the end of production and this process toughens and de-stresses the material.
Can you make V-12 crankshaft??
Yes , Arrow can make all sorts of crankshafts.

It's very hot!
@@MEDEngineeringTechVideos oh ok
@@MEDEngineeringTechVideos Yes, you want the chips to carry away as much heat as possible.
ARROW RACE CRANKSHAFT ASSY BILLET STEEL
What is the crank for? 😀
This one is for an inline A-Series engine, so MG Midget/Sprite or similar.
@@MEDEngineeringTechVideos thanks man !!!
Arthur McHugh
The crank is for making up-and-down go roundy-go-round.
@@stevedoe1630 ok ok you got me 🤣🤣🤣🤣🤣🍺🍺🍺
Engineer's ballet...
Vibratory rumbler benefit ??!!
Removes burrs and sharp edges.
