I sent Daniel a spreadsheet of custom cam specs for an FE roller cam. He replied that he could get close. Placed the order 3/09/24 and received the cam 3/14/24. Excellent grind quality. I was fortunate to get in while they were already grinding FE cams. I completely understand the struggle of a busy shop and customer service. I appreciate the attention given. Howard's was 6 to 8 weeks out..... Thanks again Daniel.
Thank you for your thorough and and thoughtful video. I'm a long retired machinist and lifelong gearhead so I appreciate how well you covered your process. 'i could almost smell the coolant. And you're correct about the equipment: folks figured out how to get that part right more than 100 years ago. I enjoyed machining so much that I actually studied up some about the history of it.
First time ever, having the cam grinding process explained. Always wondered, how the machine was set up.. Very interesting! Thank you. Merry Christmas, to y'all.
Really enjoyed that! The two things I haven't done in the engine remanufacturing industry is weld crank journals and grind cams. Thanks for showing and explaining.
I've always wondered how this operation was done. I find it very interesting, especially the machine set-up. With your close attention to producing quality products, I will have start buying from you. Thank you for taking the time to put these videos out. Subscribed!
In 1976 my dad took me to Iskenderian cams for a tour. I was able to see a Norton cam grinder in action and dyno room where they test new cam designs. I was told the cam grinder cost them 1 million dollars. That was a great day.
Thank you for your video and explaining the process. I'm always so amazed and thankful that people are sharing their skills and knowledge with others. I am in awe of your precision on getting things right. God bless you sir. You are my new Machinist for my next build
Fascinating. Are you able to regrind/restore older, worn cams? I always wondered how that process worked. Love all your videos. Especially the narration.
Awesome, nobody shows this stuff. Appreciate it, also I would listen to your awesome accent and voice talk about literally anything ahaha. Cheers brother
I cant believe how simple this is. Carve out your Easter egg and use it as a jig on the lathe to make your cam lobes. Thanks for the video is is fantastic.
Lol, yeah, definitely not that simple, the lobe profile is computer designed and then generated on the master plate in a 1/2 million dollar grinder., but producing the cam after that is definitely not rocket science!
Hitting a home run in baseball, shooting 1,000 yards, Throwing a touchdown pass.... all relatively simple acts, but the science behind them and the skill to do it... that's the extraordinary part. Cam grinding sems that way. Knowing what all goes into that grinding operation makes it fascinating! Loved watching the grinder bring the profile out of that blank.
Thanks I've always wondered, I worked in auto machine shop in the late 70's in S Cal doing rods, heads, & blocks but we didn't do cranks, cams or balancing there.
Holman Moody used a manual cam grinder when I worked for them in 1961. Joe Rump was the cam grinder and Fred Lorenzen was their driver at that time. Joe indicated each journal for runout after grinding and corrected if necessary to + - .001 TIR with a pneumatic peening tool.
@@powellmachineinc I've wondered about the angle being wrong on flat tappet camshafts about the same time the grinder may be cutting a roller than a flat tappet and may not get the angle on the machine set right. In the old days that might not have to be changed
Great.video! Curiosity though, as this is a roller cam, there’s no taper necessary in the lobe for lifter rotation. How is that ground in a flat tappet cam? Maybe it’s shown in another video? Thanks.
Finally got to this video! This was a great introduction to how this process works. How would you go about re-grinding a cam that you don't have anything on, or do I need to keep watching videos because you covered it? I am sure this isn't something you would normally do as you are running a business and you need to get work in and out, so I wouldn't expect this to be something you actually do, but my curiosity stems from liking obscure and oddball stuff that has basically zero support.
For 10k plus rpm stuff the 8 decimal place accuracy may pay dividends, but the set time and programming will make it unprofitable in a one off shop like mine, we grind 1 cam at a time for the customers application, so unless you're doing 10 plus pieces of the same grind I don't think it would ever pay dividends, IMHO.
If I supplied a cam from a tractor could you grind one just like it. It would be steel billet and about 36" long. Could I supply the blank just round or would you need the lobes roughed in?
we can do as much or as little of the work as you like, we are backed up on projects, so a std grind would be relatively fast , to turn a spool into a ugl core may take a couple months depending on heat treat ect
@@powellmachineinc it does not need a gear and it would need heat treated after lobe roughing. I'm a machinist and I could rough the lobes in but not sure it would be worth my time. I would have to do it with a dividing head on a bridgeport. I have a cnc mill but its not a 4 axis mill. There would be no hurry. Maybe over the winter
Could you give me a price on a basically stock Camshaft for a 455 Olds. I'm terrified of buying another comp cam because I lost it because of it whipping out. I have the stock cam out of the original motor but it has a worn lobe or 2.
Good information-thanks 👍… Question on flat tappet lobes ….is the taper ground in over the entire lobe or only at the peak. Reason I asked is that a supposed expert claims that the taper is only ground on the peak and this done by a grinder that rapidly offsets the angle of the wheel at the peak…

We really appreciate the opportunity to make a camshaft for your project!!
You are the only person to teach how the process of grinding a camshaft in youtube.Thankyou very much.
You are welcome!
Awesome video! Rarely seen stuff here. Thank you so much for posting!!

Glad you enjoyed it!
Thanks for showing this. As a retired tool & die maker, I can appreciate the craftsmanship you do.
Thank you very much!
Wow, what a great video explaining cam machining and some of the considerations for valvetrain design. Just awesome.
Glad you enjoyed, feel free to share!
Good video Daniel.
Thanks for giving an in depth look into cam grinding.
Merry Christmas.
Take care, Ed.

That’s what I run mine is a turbo cam a solid roller grounded by isky
In 1976 my dad took me to Iskenderian cams for a tour. I was able to see a Norton cam grinder in action and dyno room where they test new cam designs. I was told the cam grinder cost them 1 million dollars. That was a great day.
Ed is the man!!
I loved the demo on grinding cam lobes ! Excellent !
Iknow Nothing about engine building or camshaft But I will I do know you are a freaking genius.

Incredible info here. Waited a long time to see something like that!
Glad you liked it!
Fantastic explaination Daniel of cam grinding👍, have learnt something new today from your video.
I thank you for that.
From "Down Under OZ" 🇦🇺
Glad it was helpful!
Great video thank you for sharing.
One thing I would like to see is how you grind the lobe and tappers tapers.
Thank you, will do
Nice video! Kinda miss doing this work. Thanks for sharing!
Any time!
Thank you for another great video!
You are welcome!!
Awesome thanks for sharing
You bet
Fascinating. Are you able to regrind/restore older, worn cams? I always wondered how that process worked. Love all your videos. Especially the narration.
We only do rollers now, but can repair them normally
@@powellmachineinc would love to see a regrind/repair of an old, worn cam.

Guess I should have clarified haha. But it’s a brilliant idea to just have your metal Easter egg to grind the cam. It works so perfectly well.

I will sell you the whole place.....lol
Awesome video easy to understand thanks for sharing!

I would like you make a complete set up a cam and lifter set up for my 347 ! Hope you have a great New years!
Message us through the website, we can take care of you.
Really cool
Definitely
Really cool 😎
Great video! I've been curious how this is done, and I've got a lot to learn before I even dream of getting into it
Glad it was helpful!
cant wait for my FE cam to get here!
That brings back memories of working at Isky.....
Holman Moody used a manual cam grinder when I worked for them in 1961. Joe Rump was the cam grinder and Fred Lorenzen was their driver at that time. Joe indicated each journal for runout after grinding and corrected if necessary to + - .001 TIR with a pneumatic peening tool.
Yep, that's how it's done
Great video. Thank you!

I always wanted to grind cam shaft former machinist 😮
Go for it!
Wow brother this is really interesting. I didn't know how it was done.
I would think your time to make this kind of video slows down your productivity but I really enjoyed it. Thanks for sharing your knowledge with us.
It does, but hopefully it will save a lot of explaining in the future.
Dang! great video
Thank you!!
So grinding a flat tappet camshaft you just tilt your grinding wheel to get an angle on the lobe
Yes, that's correct
@@powellmachineinc I've wondered about the angle being wrong on flat tappet camshafts about the same time the grinder may be cutting a roller than a flat tappet and may not get the angle on the machine set right. In the old days that might not have to be changed
@David Reed it's possible, but it would be a rookie operator to do such a thing.
Another fantastic video/ great explanation. 👍
Glad you liked it!
Great.video! Curiosity though, as this is a roller cam, there’s no taper necessary in the lobe for lifter rotation. How is that ground in a flat tappet cam? Maybe it’s shown in another video? Thanks.
Haven't done that video yet, but we dress the stone with the proper taper, but we have all but stopped doing anything but rollers.
That’s amazing, I wish I had all this knowledge. Great Video 👍👍👍👍
Thank you sir!!
Fascinating!
Very good video!
Thank you very much!
Thank you for your knowledge and video's USA 🇺🇸
Thanks for watching!
Awesome. Just found out where you’re located.
Thanks! I always have wondered about this stuff....
You're very welcome!
I always wondered how they grind cams now I know 👍
💯
Finally got to this video! This was a great introduction to how this process works.

I am sure this isn't something you would normally do as you are running a business and you need to get work in and out, so I wouldn't expect this to be something you actually do, but my curiosity stems from liking obscure and oddball stuff that has basically zero support.
How often do you need to dress the grinding wheel to be sure it is still straight/flat?
Once to rough grind and once to finish grind, on steel, a little more for Ductile iron
Very interesting. How do you set the lobe taper for flat tappets?
We set the grinding head on the proper angle
Is this a single pattern cam?...totally awesome video
No it's dual, 226/230, thank you for watching!
Ok, I must have missed something....did you change the master before you switched lobes?
@Duane Dahl no, there are 2 masters stacked one behind the other, look at it again you can see it.
@Powell Machine Inc nice video, do you sell ford fe solid roller cams
Nice video.
Thanks for the visit
Question, can a flat tappet cam be reground for roller lifters?
No, the gray iron won't live, and the nose is way to small
Thank You!!!
You're welcome!
Good 👍😊 stuff thank you Sir
My pleasure
Hell Yeah Super Cool
Thank You
Great information an video
Glad you think so!
I must ask you if you make up cams for people? Thanks for the video.
Yes, that is a major division of my business
You just answered a bunch of questions I have had. I didn't know they had different lift, duration and lsa cam cores.
Do you design your own lobes?
No, I am definitely not a lobe designer, we have 2 professional lobe designers we use.
Mr. the size of the grinding stone you use using grit
@@cnccams1428 18", I think there 70 grit
Do you guys do regrinds? Like my Gen lll Hemi. Thanks
Yes there is actually a video here on my channel of that very thing.
So if I order a solid roller cam you could make it right?
That's what we pride ourselves on!
I know, if it aint broke don't fix it . But other then the speed of churning them out , any real advantages of the new CNC cam grinders ?
For 10k plus rpm stuff the 8 decimal place accuracy may pay dividends, but the set time and programming will make it unprofitable in a one off shop like mine, we grind 1 cam at a time for the customers application, so unless you're doing 10 plus pieces of the same grind I don't think it would ever pay dividends, IMHO.

we can do as much or as little of the work as you like, we are backed up on projects, so a std grind would be relatively fast , to turn a spool into a ugl core may take a couple months depending on heat treat ect
What would cost be to machine the lobes from a round turned blank
6cyl john deere
It will have to be heat treated after lobe milling, also does it need a gear hobbed? Also all the main journals will need finished after heat treat
@@powellmachineinc it does not need a gear and it would need heat treated after lobe roughing. I'm a machinist and I could rough the lobes in but not sure it would be worth my time. I would have to do it with a dividing head on a bridgeport. I have a cnc mill but its not a 4 axis mill. There would be no hurry. Maybe over the winter
Could you give me a price on a basically stock Camshaft for a 455 Olds. I'm terrified of buying another comp cam because I lost it because of it whipping out. I have the stock cam out of the original motor but it has a worn lobe or 2.
Rollers are 450.00 pretty much any street grind,we couldn't go stock though
Good information-thanks 👍… Question on flat tappet lobes ….is the taper ground in over the entire lobe or only at the peak. Reason I asked is that a supposed expert claims that the taper is only ground on the peak and this done by a grinder that rapidly offsets the angle of the wheel at the peak…
Correct, the taper follows the full circumference of the lobe, that's how it works.
@@powellmachineinc thanks …that is what I’ve always believed .
Thanks
No problem
Good 👍👍
Thanks for the visit
Cool
interesting vid.
Glad you think so!
Can you now sell me a solid flat tappet can that won’t wipe out?
Ww stopped grinding Flat cams 2 year's ago, there is no money in them
@@powellmachineinc that’s sad but understandable. They used to be a good option to a solid roller.
Fascinating. Shame I live half a world away, otherwise you would have my business, small as it is.
Thank you!! Would be glad to have your business
way above my pay grade, when it comes to the technical side of engines it seems the more i learn the stupider i get.......
We all feel that way at times!
