In the past I never would have considered Lunati for a crankshaft, but after this video you now have much credibility with me, Thank you for the video!

[@donellmuniz590]

Lunati, Crower, Callies, I'm sure they're all equally good. Then ya get into the REALLY spendy stuff like Winberg, Bryant, etc.

[@donellmuniz590]

I wonder how they stack up against Scat and Eagle, two companies a bit lower on the price point.

[@mannycalavera121]

You guys rocking some real old school CNC machines there

[@robertngates4246]

Anything over 1/10000 of an inch to me would be considered a grocery getter engine part.lunati should really consider this video as a oh no moment

[@paulsutton5896]

So which engines are they for?

[@chuckchase8432]

Down to .004" of an inch. damn, Didn't know Tajikistan could do that good. I'll keep buying Scat. Listen to your video before posting!

[@chuckchase8432]

Their used to be a man in Tucson AZ who could take .0003 off a journal if you asked for it! He's still working but closed his shop.

chuck chase uhń

@the machinist Better man than I. Best I do is take 5 tenths off a main or rod.

[@chuckchase8432]

@the machinist Thought I f--up. Listen at 4:57

[@bryanduncan1640]

Surely this video should be called “How we took somebody else’s crankshaft and cut/ground bits off of it”?

[@libertarianlife3651]

AT 5.48 THE GUY SAYS " THESE ARE CHECKED DOWN TO 4 THOUSANDTHS.".OUCH I'M PRETTY SURE HE MEANT 4 TEN THOUSANDTHS. 4 THOW I CAN DO WITH A HAND GRINDER.

[@bluesbastard81]

libertarian life , Hi , they said 4 ten thousanths , that's .0004" not .004" . .0004 is a realistic industry standard , they probably end up within .0002 - .0003 of spec with polishing probably on the minus / undersize side on purpose . I wouldn't buy one though , place is lower tech than I thought . I know there tough forgings though .

[@whiplashmachine]

@@bluesbastard81 at like 4:50 or so they said 0.004". It was an error but that is what he said. I have measured many and they are nice quality cranks.

[@stanieciaward827]

damn...

[@gazza116]

.004 dont go over 540 rpm.

[@alexlukac8852]

Nice video ,Att : To Lunati General manager.You need to by a new chuck key, looks very bad in the video, plus your operator ,have chance to damage his hand new key not expense ( do not by chinese brand are cheap on material ) not give a long life to used. Detail on top your tool post on Lathe machine , you have a repair nuts (machining nuts with shoulder) welding a handle on side, looks bad in the movie. Please make new nuts to tie tool holder, improve your machine shop , details Thank you

It could be 1966

[@nitromethane222]

It didnt show you how they were made at the foundry are they forged in the USA or the same place eagle cranks are made China

[@bluesbastard81]

nitromethane222 , They are overpriced . Just a bunch of marketing hype and some guys dream . I would never buy one after seeing this video. A scat or eagle I'm sure is better quality because they make more of them . I'm a machinist and this place is really , really old fashioned !!!!!!! I about puked when I saw them rigid tapping the front snout in a manual lathe just chucked !!!!???? That should be done in a cnc with a single point tool for God sakes especially for what these jokers charge . Overpriced crap !

[@nitromethane222]

@@bluesbastard81 You never drove anything over 200 MPH These are far better cranks that Eagle Chinese made shit I actually run Bryant crank shafts

[@bluesbastard81]

nitromethane222 , You're write about the 200 mph !!! I know there tough , just the shop in this video is on the low tech side as far as equipment goes . I had the mindset the shop would have some really high tech equipment ! Check out Scats video they have some really nice modern equipment . They all use some manual lathe and mills for good reason but these guys have some dinasore equipment !!!! Just saying for the $ I'd expect more .

[@bluesbastard81]

P.S , I never heard of Bryant cranks I'll check them out !

[@Frank289100]

THAT WAS THE FIRST THOUGHT THAT POP INTO MY HEAD IF THEY ARE CAST HERE IN AMERICA?

[@MegaJohnhammond]

you've got some real state of the art equipment there. For 1975 that is

[@DR-br5gb]

You look like a child. So if you're not, you're an idiot instead.

[@donellmuniz590]

Well, no wonder the damn things are so expensive!😕

[@bluesbastard81]

Damn , I guess a bunch of marketing hype !!!! I'm a machinist and this place is actually very old fashioned !!!! I bet they're imported forgings , rough machined then they finish them . I'd rather use scat or eagle , imported as well I'm sure but a hell of alot cheaper ! At the end of the day a crank needs to be made well but it won't make or break an engines performance .Gun drilling the center mains " the big center hole " only weakens a crankshaft !!!!! I would never use one. Drilling the rod throws is the biggest advantage as far as drilling holes goes. I ran a stock small block Chevy cast iron crank at 6600 rpm in a drag car for thousands of runs and it had no issues ! Was over geared and ran 12.5s but it sounded fantastic ! Buy better heads and don't buy crank with your money kids !!!

[@tedgerstenslager2949]

And what pray tell are Scat and Eagle, Manley, Molnar? Hmmm, Can I have offshore for a dollar Alex. Im pilot, I can fly, sir

[@bluesbastard81]

Ted Gerstenslager Your reply is totally improperly typed and incoherently laid out , similar to a cheap Chinese parts which you probably use alot of !

[@hellohun7331]

Down to four thousands of an inch? Try four ten thousands of an inch.

[@red7fifty]

Pimp my engine!
