Some machining processes look like magic , this is definitely one of them . Thanks for showing us what's under the hood of making what goes under the hood . And a $170 regrind is a very nice price too .
Love your videos man....especially this....there was a man here in Carter county Tn. back in the day that re-ground cams for Junior Johnson back in the day.....J.B. Hyder out of a little machine shop here....still have a cam he ground from back in the 80,s Hydraulic s.b.c. that is still going....this is meat and potatoes of a engine....keep up the good work.
Your ol school man and put alot of love into your work....like the oltimers did,unlike today,s most. keep up the work you do man...really admire your work,Chris from East Tn.
Love watching these videos. I am in a designer and machinist in the plastic molding industry building tooling and fixing tooling and all which has been fun but this type of machining is what screams to my heart lol! Love the way you explain the details of why something is being done. Can definitely tell from your knowledge why you are successful!
That's really cool. It's the first time I've seen a cam ground, muchless the intricacies involved in it. I've always THOUGHT that it was pretty simple to do...until now. I've never watched one of his videos yet, where i didn't learn something, and where I've gotten bored.
Thank you! I always wondered how a cam could be reground into a more performance oriented cam. Been learning so much! That price of 170.00 is a damn good deal in my book.
love your videos of the rants but videos like this are my favorite. they help me get through my workdays like today that are slow and uneventful. appreciate your hard work sir.
Considering the amount of time,the knowledge and experience involved in this process $170.00 is very reasonable. Thanks again for sharing your expertise.
You are in a world that most guys need to stay out of. Sounds like you have done enough cam grinding to know the ins and outs, I would damn sure not want to spend the money on a new cam grinding machine until I had the opportunity to work under someone like you for a year or so. Great video!
I just found your channel recently and like the way you explain things. Very well done videos !! Thanks for doing them . I have been in alot of automotive machine shops in the last 55 years and never seen a camshaft grinder or a cam being ground very interesting.
I'm glad I found your channel. So much engine machine work well explained, which I always wondered about exactly how it was done! One thing that might be cool for an illustration of cam grinding is a close up of the grinding process with machinist dye on a lobe so we can either watch in slo-mo, or you do it in editing so we can see the full progression clearly.
Hey Daniel, Tim here, one of the MOST enjoyable vids u've done, i know cam timing events, and specs pretty well.....NEVER knew the machinist side (which has driven my crazy for years) and if you remember i'm a machinslist nerd type dude, i was GLUED to my phn.....just KICK ASS!!.....the cam in my hot rod was a re-ground Super Stock cam.....but still quite lumpy...(in my 462 Poncho).....NOW i know why, you can only go so far, with the material u got to work with.......i just LOVED this vid.....makes me wanna ask you if YOU got a hot rod......hope ur foolin with somethin.....MAN i dug this vid...TY sir, i wear my T-shirts PROUDLY!!!......keep doin ur thing, us machinist nerds smile!!!
Really do enjoy your videos, might think about putting some of your Powell Machine labels, stickers on your machines. This way when you are videoing your name is always out there. Have a great weekend.
Your instruction are precise and informative. Also putting it in layman's terms is an added benefit for those of us novice engine builders. Providing the technical aspects of what you do is helpful in learning. That being said, grinding the cam lobes change the push rod length but the lifter stays the same. I'm still learning and thank you for any response.
I'll be the first to admit I know nothing about cams it's just amazing what you can do with regrinding cams that was an awesome video I wish I knew a little more of what you were talking about but again an awesome video buddy
I was just searching yesterday if anyone can regrind an AFM cam! And then your video pops up! I won't toss my core in the steel bin now! Damn I wish you guys were closer. I'll have to price shipping? Thanks for the video. You do great work for a blind guy!
@powellmachineinc3179 I'm in Canada not sure what shipping would be? I appreciate the great work and videos! I'm sharing your videos north of the boarder!
I !over modifying stuff. This is awesome, much better than the cam I reground for a motorcycle as a kid, using belt sander!! It worked, don't know for how long I just removed some base circle and polished the nose,
Great videos.. learn something every time I watch ..Please make video of offset grinding a crankshaft..I’am no machinist.. I would think it would be similar to regrinding a camshaft..
I can already see that I'll have to watch this one ten times ....at least . Thanks for all of your hard work . That's to the entire family , team work works .
Back 19 or 20 years ago , I had what we all thought were valve problems . They were all Honda CRF 450 and 250 motocross bikes . Most of us , not being professionals , threw money at valves. Specifically , most of us replaced the stock valves with Kibblewhite products . They helped , but didn't solve our issues . Turned out to be cam issues . The factory cams were allowing the valves to slam shut ...rather than letting the valve meet seat gently in the last few degrees of rotation. Of course Honda wouldn't admit it was on them . The aftermarket cam folks figured it out , but it took awhile . Interesting stuff for a " Corn Bread " such as myself .
I was always told the DOD lobes had a smaller base circle to account for a taller lifter, which causes a misfire with normal lifters. I've also heard of a weird ramp (a dip) to ensure the internal pins momentarily are unloaded to ensure they lock when going into v8 mode. Just isn't enough when 10k-mile oil change intervals clog them up.
Question. When you are talking through the process of aligning the drive dog for the centerline, initially the lobe is sloping down and towards you, then you flip it 180 and it sloping down and away from you. How do you know that you are on the same plane on the 2nd side of the lobe that you were on the 1st side you checked? Seems like there would be some room for error there? Thanks for the great video. I'll definitely be getting DOD delete cams from you in the future.
Great video. Crazy how you can take away material and make the lift higher. Can you explain in a video please. I’m not a machinist. Very cool to learn new stuff
If you take away from the base circle, the cam follower to cam clearance will be adjusted to compensate, which then means more cam lift. Remember cam lift is the difference between base circle and lobe height.
I believe it is the difference between the height of the lobe minus the width of the lobe that determines the lobe lift. Mr. Powel can confirm this or correct me.
that was great. Cam grinds have always seemed like secret voodoo to me. But even here it is hard for me to understand that you took material off of the lobe apex yet you have increased valve lift.
that was a super video...!..that explaned "why" instaling a cam on it's centerline (or adv/retarted) is so important...!..a lot of guys just slam the cam in heads up...& run it ...!..i got so many questions rattling around in my head after watch'n....just quick'y.: im guess'n that lobe profiles on a flat tappid cam are more involved since the peak of the lobe is steaper than on a roller cam lobe...?...is that near correct...?..?..& there more limited cause of the shape of the lobe...?..?..thanks great video...! look'n forward too more...!
Dam brother, that is really interesting. I am building a Ls3. I have a set of stock lifters with less then 40k miles. The truck they came out of got t-boned. It was a Ly6. No dod. Would you run them? Or just buy new?
Wow, absolutely fascinating! Can you explain and maybey show that guides the profile as the cam moves to and from the grinding wheel? Is there a master profile synced to the cam rotation that moves the rotating cam in/out?
You mentioned after Grinding the Intake Lobes, you then use the LSA to dial in the Exhaust Lobes, do you change the Grind Master to Exhaust at the same time as you mentioned the intake and exhaust profiles are different. Also do you make your own Masters or do you get them machined elsewhere based on your Lobe Design?
Yes, we swap to a different master for exh, yes we produce our own master plates, we also make master plates for other cam companies also. And other cam grinder tooling
Just started watching your channel so forgive me if this question has been asked before. What is the cutting/grunting fluid you are using? It’s interesting how clear it is. Is it a fully synthetic coolant?
Very interesting! Do you always plan for use with standard rocker gear with your cam regrinds? Or do you sometimes specify a different rocker arm ratio?
I used Rhoads lifters decades ago (and they still exist) that had a longitudinal v-groove ground into the outside of the lifter plunger to allow controlled bleed down at lower speeds. I suspect that's the mechanism they use these days as well. The higher the RPM, the less time each lifter had to bleed off effective height, so the valve lift and duration were reduced the most at idle and the least (maybe not at all) at high RPM. I'd like to see someone run a back to back test on an engine with a pretty decent cam in a Gen III LS (they don't offer lifters for Gen IV LS or newer) to see if they really do increase vacuum at idle and increase low end power as they claim.
Checking out your video and wondering if you do air cooled VW cams…I just started back helping Pat Tafta he’s getting back into building VW engines…Hot Rod and Street stuff….
This seems like a smart(money wise) solution to having to buy another part just so there's enough material to allow the contours you're after. I'm a dummy as these things go & should we trust the after market parts to be made of the right material(hardness) or is the original cam from the manufacturer more likely to be made from the proper grade of steel? And once you've bought it & installed the part it's yours..... lol, that would be a hard lesson & I'm sure many have learned it but today I learned that in some cases you might be able to use one that's reground. If one thing is out of whack the whole thing is corrupted = expensive. Thanks for the video, Mr Powell. peace & GB ALL
Great content Daniel as always. When you grind a flat tappet cam does the taper come from a tapered grinding wheel or is the bed set up to include the taper?
Very interesting although I am not very well versed in cam mojo. I may give you a buzz about regrinding a cam I replaced in my ZZ4. I just need to look how severe the damage is so I don't waste your time. I'm really enjoying your videos.
HI DAN GREAT VID. ARE ALL CAMS FLAME OR INDUCTION HARDENED FROM FACTORY? I REMEMBER BACK IN 77 THE GM 305 SOFT LOBES ON # 5 AND 7 CAM LOBE BEING SOFT. JUST WONDERED ABOUT THE DEPTH OF THE FACTORY HEAT TREAT?? THANKS. KEEP UP THE GREAT VIDEOS.
As a fellow sufferer of "blind in one eye and can't see out of the other (close up)," take your phone out, put it on camera, and enlarge it to see what you're looking at, if you haven't got your cheaters handy. On my phone, you can't use the flashlight and the camera at the same time, but you can take a picture with the flash to see what you're lookin' at.
Hey can I send you my Cam for a 4.3 Vortec V6... I am looking to get a little more lift and a little less valve overlap because I am biulding engine for my S-10 I ported the heads. I am looking for a little less overlap and maybe about .025" to .030" more of lift to gain some Dynamic compression since I am going with boost.
$170 for a regrind sounds more than fair. That’s pretty cool. Great stuff man.
Ty!
And know it was done correctly.
bargin
Yeah and it will ad about 30 hp wheel 30tq ?
Even more so because they're VVT, which are usually really expensive from the aftermarket. The biggest is the L92, which is only 198/209 0.500".
Thanks for taking the time to break down this process. Love opportunities like this to expand my knowledge of related topics of interest.
You're welcome
I've learned more about camshaft design from watching this good ole boy!!
@randygandee9674 tyvm! Glad it's helping
Thanks for posting this video. Ironically I was just googling how cams are reground.
Good deal
As an amateur machinist and lifelong automotive enthusiast, watching this is truly fascinating. Educational as well! Best of UA-cam.
Thank you very much!
I always understood the concept of the regrind but have never seen the actual process, thanks for showing and explaining that to us.
You're very welcome!

Very helpful, and entertaining.
I will probably watch it several times to get my head clear on all of it.
Thanks!
Glad you enjoyed it!
Love your channel man!!! It kinda just popped up in my feed and I’ve been watching every video since! Keep up the good work!!!

Great information and VERY cost effective
We agree!
I watch to see the machining process and the tools used to do it as much as learning more about engine components and engine related tips.
Great video! Keep the info coming.
Thanks! Will do!
Excellent my 13 LS has over 200 k I need the DOD delete now I know where to get a cam to use with the factory components Thanks for the video
Tyvm
Thanks for sharing never knew how that was done with cam. Being im crankshaft grinder my self
No problem 👍

Everything but that haircut was great. Love the videos. Keep em coming.
Lol, what's wrong with my haircut?
I've never seen a cam being ground, that was cool. I have seen high speed turbo compressor pinion shafts being ground but that was just round shaft.
When you get your filming together you’re gonna have a great channel!
Easy to learn a lot from your videos. Thank you for sharing.
LOL, "All the above" , Yes it's why I love watching this channel, very much worth our time learning this.

Thanks for watching!
Easy to watch and understand.

So easy to understand 👍👍
Glad you think so!
Great video as always. If I ever do a DOD delete I know where to get the cam now!
Definitely
Loong draawwls on woords...just slays me.

That is 💯 incorrect, the bc is the same and the activation/deactivation happens on the base circle
Amazing! More please.
Absolutely
Thank you! @@powellmachineinc

I'm not sure what your asking exactly as I thought I explained it clearly in the video,
As a 17 year old novice mechanist this is so friggen cool

It would be interesting to see you work with Richard Holdner and him test one of your cams in his LS test motor.
We reached out to him when he started and he blowed us off...... I guess all those big names are paying him to much to pimp there stuff
He's from Washington, DC, that should tell ya right there !!!
Keep them coming, boss !
More to come!
Very interesting Daniel.
How much off the .035 was the base circle?
Do you ever have to get longer push rods?
I appreciate you sharing the process.
80%, yes in some applications, but the ls has WAY to much preload already from gm so no issues
i love all your videos
Thanks!!
Dam brother, that is really interesting. I am building a Ls3. I have a set of stock lifters with less then 40k miles. The truck they came out of got t-boned. It was a Ly6. No dod. Would you run them? Or just buy new?
Wow, absolutely fascinating! Can you explain and maybey show that guides the profile as the cam moves to and from the grinding wheel? Is there a master profile synced to the cam rotation that moves the rotating cam in/out?

Very interesting. Thanks for the post !

That cam grinder requires a profile form tool disc to make shape, how do you generate/ buy yours...
In the cnc
Very interesting! Do you always plan for use with standard rocker gear with your cam regrinds? Or do you sometimes specify a different rocker arm ratio?
Most would be designed for stock ratio unless the customer or us decide otherwise, it rather put lift in the lobe that a lot of rocker ratio
@@powellmachineinc Thank-you. I'm learning a lot through your videos.

No.
.
I'm curious as to how often you dress the stone and how long the stone lasts. Enjoying you videos, thanks.
Normally on a new billet, once to rough grind and once for the finish pass
@@powellmachineinc Thanks.
It's awesome to see how you regrind these. Do you happen to grind/regrind cams for the Ford 2300 Lima engines?
No, sorry
Good stuff man I have a vvt cam in my Cadillac Escalade
Keep up the good videos
Always
Checking out your video and wondering if you do air cooled VW cams…I just started back helping Pat Tafta he’s getting back into building VW engines…Hot Rod and Street stuff….
Incredibly cool.... So you could re-grind a stock LS2 cam into a little bit of a sleeper cam....
Definitely
@@powellmachineinc That is cool as hell.
This seems like a smart(money wise) solution to having to buy another part just so there's enough material to allow the contours

Tyvm!
I've been grinding automotive crankshafts for decades, regrinding camshafts looks like witchcraft to me.
Lol, I hear that often
Great video. I understand the concept but seeing it done is icing on the cake. How do you grind taper on a solid or hydraulic flat tappet?
We dress it into the wheel
I am sure there is a good reason but why do you not use a bearing center instead of a dead center at the tail-stock? What does a blank cam look like?
I got a 2013 Suburban LC9 5.3L that I would love to do this too.
Send it in....
Dan I have a cam that I would like to change the 050 duration from 228/230 to 218/224 and the LCA from 112 to 110. Is this possible. Thank you.
Duration, no problem, the lsa , maybe
@@powellmachineinc Thank you.
Great content Daniel as always. When you grind a flat tappet cam does the taper come from a tapered grinding wheel or is the bed set up to include the taper?

Are you able to regrind to a higher lift , 585 ? Maybe with a 108 or 112 separation
No, there isn't enough material for that
Cool! May you tell us what to think about cam profile versus rocker ratio?
Hey can I send you my Cam for a 4.3 Vortec V6... I am looking to get a little more lift and a little less valve overlap because I am biulding engine for my S-10 I ported the heads.
