I was in instructor for over 15 years, and I still have a few interns in the shop every once in a while. Thanks for the kind words, and Happy New Years down under.
@fiatnutz that explains your fluent explanations. you should do tips and how to's more often, altough everybody loves your machining videos. just gives you feeling like you are talking to your machines not just using them ;) cheers!
Hi Sir, When I see grinding process I notice one side of the cup wheel is in contact with surface. Is there angle at rotary head? How you dress cup wheel ? All surface of cup touches to surface or only tip of the cup touches. Thank you
I had a pothole flywheel and I grinded to make it a flat one (like the one on the vid),so I can attach a different preassure plate and clutch.Anyways,after I did so,should I balance it again? Right now,the flywheel is just a solid disc... (like the one you just did in the video),so I'm wondering if I should... some people say yes,other say no... I don't know what's right
Hi John, When buying a used flywheel, would i need to resurface and balance? Also, can you break down the approx costs for each svc? Thanks alot for any info and superb vids.
In the absence of a grinder like yours is it not feasible to do this in a vertical milling machine with a rotary table and a suitable she'll mill with either carbide or boron nitride inserts? I understand the reasons for using a mill over a lathe but I do not have a dedicated flywheel grinder like you have. As an un preferred option could a cup wheel be mounted on a suitable arbor and used at a fast speed in the mill? Not keen as don't want the abrasive dust getting on my ways but extra masking procedures could be carried out. Thanks for such interesting videos John. Your lovely little Fiat would be perfect for racing up my local hill climb track, Gurston Down. We have a great web site and photo archive if you get a minute.
@ribak1983 I would rather have a reground flywheel simply because even from the factory they can be out a thousandth or two. Some people have brand new flywheels that are out quite a bit from the box.
that was pretty interesting to see. This is the first of its kind for me, I didn't even consider this kind of machine, but it is cool. A bit niche.. Is there a big market for this kind of grinding job?
for a machine shop maybe nothing less/// maybe a busy parts store. i would turn maybe 4 a month in the winter.. 2-3 a day in summer in denver and charged 50$ a flywheel and no one else offered to do it anywhere near me. it really is filthy worth you have to clean these machines often and you need a mask to run it or else you'll get that dust in your lungs ( and clutch material still uses asbestos ) i would use a diamond cut wheel ive had too many of those stone ones blow up
Dear John, I`ve contacted you on 2 previous occasions about my Land Rover diesel engine and had no response. Have you stopped replying to your emails? Paul from England

fiatnutz poop
Sure do miss Ole John....
Nice work, as alway, John. Many thanks.
very professional job!
I watch every movie, great job. Many greetings from Croatia
Men, you are the best! I learn a lot with you!
Used a flywheel grinder in our tool grinding shop
We do brake disks with our machine too amongst other things
Crazy. Every time I have a question there's a costa mesa R&D vid with the answer. That's really awesome John. SUBSCRIIIBED!!
John your machine shop practices are always well explained and shown , did you ever think about being a teacher? and thanks for another great clip.
@benthekahn - I have mounted flywheels on my lathe and used a tool post grinder to machine them.
@fiatnutz that explains your fluent explanations. you should do tips and how to's more often, altough everybody loves your machining videos. just gives you feeling like you are talking to your machines not just using them ;) cheers!
@briggsandclones - Its a cup-style aluminum oxide abrasive stone spinning around 3600 rpm.
Great work brother 👍👍👍
Please educate me on something, is flywheel and disc the same thin and if not do they need to be resurfaced????
Don't know, I've nver been put inside an envelope before. ;-) But, if you are asking if we get things shipped to us for repair, yes all the time.
Could a fixture be made to do this with a grinding stone and lathe, essentially rotating your machines setup 90 degrees?
@fiatnutz thanks mate happy new year to you too.
Does grinding the flywheel to resurface lighten it in any noticeable way that would increase performance?
Hi Sir,
When I see grinding process I notice one side of the cup wheel is in contact with surface. Is there angle at rotary head? How you dress cup wheel ? All surface of cup touches to surface or only tip of the cup touches. Thank you
@fiatnutz I live on the other coast... I was merely curious as to what the going rates are.
nice setup... :)

I'd imagine that very large flywheels have been ground on VTLs using a special ram attachment.
NIce!
How much on average would it cost to bore a small block Chevy .060" over?
should see my flywheel grider havent seen any similar
So what about the deck height? I mean the step is ground off. Mine has 2 heights and needs to stay that way. Toyota 4x4

sure, use a grinding cup trued up. spray bottle of coolant. flywheel on rotary table. mill trammed.
I wonder how well a diamond cup stone would work...

@YoungJim409 - Yes it does, I do the brakes on the race car this way after I have them cryo'ed.
@cubcadetpuller - SAE #2 from a Cummins Diesel, also used on some Detroit Diesels.
how do u grind a flywheel that has a lip on it like my subaru gl
hi people, is it worth it to reface original flywheel or just buy for 55$ new one
What make/model is this flywheel grinder?
appears to be a storm, it looks a lot like a dcm though.
hey john do you guys do work like mail in stuff ?
me gusta cuanto cuesta presupuesto
@YoungJim409 - Same machine.
Have it checked, at a minimum.
AWESOME :D Is that cutter similar to a large facemill?
@donbehatin - If you are local, call me.
@timgowd - No.
Parais...nu

Sorry to tell you but John is dead since a few year back.
Indian supply er name
Fk it were all robot electro spaceships soon
u clearly took of too much metal its broken put it back in the honda ef9 it was from and tell the customer its fine
