I Worked in a small engine shop that took old cams and welded big blobs onto the lobes and would make a custom grind. The machine was hand built and used a series of bearings on shafts that rode an original cam and they could make adjustments to how much duration and lift they wanted to add by simply turning a few screws that lifted or pressed the riding bearings. it was attached to a grinder to bring a rough shape back to the lobes then a series of cutting tools would go to what you set the screws at on the bearings, then they would polish the lobes on the same machine with a modified belt grinder that rode the same guide machine.
It's amazing what some of the old timers would come up with. They were the true mechanics and machinists that actually fixed a part not just replaced it.
Same here. We raced karts in the 80's and 90's and we ground our cams the same way.
We built a "copier" that actually ground the lobes with a bearing mounted motor with grinding wheel that was water cooled. I would grind the correct taper so the lifters would rotate correctly. Could adjust lobe separation, duration etc. by some adjustment screws. Won a ton of races because we had cams that others could not get. Good times
👍
I would love to see that machine in action!
@@Ever443 dear sir, I increased the duration in a camshaft but the taper (in stock cam) you mentioned that I can’t get while increasing the duration, so my cam make tapping noise and loss in power. Advise me how can I rectify. Can I get your WhatsApp number if you wish. Thanks 😊
Very nice work! 👍👍
The hardening parts is really difficult ,the japanese factories had big problems with it ,according to motorcycle magazines since the 80s. My Kawasaki Z 750 twin was one of them.
You are so far above my skill level that I am in awe of your ability and work.
How about showing how you did the second lobe without chewing through the top lobe or sprocket carrier. .Very handy skip past the only info I needed to see.
I think the same as you
In future videos
I would have used a large enough T-slot cutter or something like that
With t-slot cutter
Basically skipped the only part worth watching
As a home machinist and because you work on ATV/Dirt bike parts, I'm often depressed after watching your work. I'd so love to be able to do a small fraction of what you can, your work is amazing!! That's the cam grinder you made to fix a 5 valve YFZ head or something awhile back, I guess it comes in handy!! That cam you made is either exactly the same or very close to the ones used in my Honda ATC350X, same motor. Those 350D or 350X cams if in good shape used are selling for just about 300$. Megacycle or Webcamshafts will make us whatever we want but they often don't have any cores or it can take months to get them made; They have to cater to their Pro Motocross racers first. I'll have to watch your rocker arm video next, that's another part we cannot buy and they are very expensive even in used form. We can get old ones hardwelded and ground for about 200$ or billet for a bit more $$. I gotto learn from a toolmaker for about a year, he was awesome but it wasn't enough time. I sure wish I were your neighbor, but then you'd wish I weren't your neighbor 😁
you need to buy expensive equipment friend, the shaping of cam knobs are been made here by cnc machine !!! all those machines he uses here are too much expensive for home use,, .ALSO there lot of work behind the camera for digitizing the original part and then programming the milling CNC machine ....
You probably could've used the old one, but now you've got a spare. And it was a high quality job.
From one machinist to another 👍
thanks for being considerate and muting audio in the appropriate places :) this is an awesome demonstration of skill, cheers!

Oh man, that lobe grinder was the icing on the cake! So, satisfying to watch the transformation. Fantastic.
Cống hiến hơn nữa trong sự nghiệp của mình. Một lần nữa cảm ơn Đức Phúc và chương trình đã mang đến những giây phút thư giãn này. Mãi yêu!!!❤❤❤
So nice to see you are using the momentum screw on the micrometer, and not the big barrel when you are measuring..
Thanks for taking the time to make the video and share it.
Hi,
how did you reached the inner cam? You showed only the outer one. Did you reach it with a end-mill with a large diameter and a small shaft? Or with a saw-blade. the marks are looking a little bit like this.
Great work!
T groove cutter
Reminds me of the old xr250, they had issues or the issues owners faced if they couldn’t be bothered to change the oil and filter and check valve clearances regularly . Result was worn out cam and rocker arms.
Great work , joy to watch
friend had an xr200r... snapped a lug off the camshaft, snapped three chains. chewed two sets of valves. snapped a pair of rockers. snapped the camshaft.
yeah. that was a lemon... never had anything that determined to not run... no reason for it, everything specced out... but damn, it grenaded after about ten minutes, everytime...
It’s amazing that it didn’t do damage to the cam journals which is a very common problem on the older Honda’s like this and the fourtrax 300, I actually have a video of one on a 300 on my channel. You are the best machinist on you tube that works on these engines by far!!! Love your channel and work!
He one of the top 3
Es un placer ver cada uno de tus trabajos.. bendiciones.
muito bom essa máquina que você usa pra dar acabamento no comando foi você que fez?
The shop made cam grinder is really slick and it looks like it takes a very skilled handle to operate it, nice work. 👍
i've got a '86 Honda magna 700 bobber that i will rebuild this winter.
now i hope the heads, valves and camshafts need to be replaced.
been a cnc machinist, still have access to them, and have a manual lathe and mill.
sounds like good old fun😆
Loved every second !
Although, I'd love to see how did you design the part in Solidworks/Fusion. I do some little work on my own, and would love to learn from you
Man, you're awesome. You're my hero 😆 love to see how you work, Im trully impressed. Some of parts you have repaired were just a trash before you started. Greetings from Poland!
Amazing ...... amazing job.....!!!
My respect Mr Paul.
I 'm waiting like crazy...for the next part.
Você é muito profissional no que faz nota dez
c'est ce qui s'appelle de la haute précision .......! magnifique 🔬🔬🔬🔬
Wow, so much work to recreate a single cylinder cam very impressed
Great video enjoyed it,Always fun to watch something from scrap to final workpiece
Thật tuyệt vời khi được xem video hay như này
With your abilities and proper shop equipment, you can now experiment with different grinds with lift and duration cams to get the best of everything... Thumbs Up!
blind following the blind.
Saya alumni teknik permesinan sangat takjub dengan pekerjaan anda ini, hebat bro! 👍
Karena saya sudah lama tidak mengoperasikan mesin-mesin tersebut, & sekarang saya sedang bernostalgia
Random question... Does the lathe you are working on towards the start (~5 min to ~10min) use controlled braking? Does it have a mechanical brake of some type to slow the spindle Or does it use DC breaking (maybe regenerative braking? I dont know what it is called but it is a function of many VFD's and requires a big breaking resistor)? Really just curious, that machine looks/sounds good :) and seems to decelerate at a good rate.
I am in the middle of rebuilding my lathe so trying to figure all this stuff out and see what options are out there. If you don't mind sharing I would love to know. Thanks!!
OUTSTANDING!
A 1986 Kawasaki 454 LTD I purchased has more and more surprises the more I tear in to it.
Kawasaki does not show any camshafts for this bike. Used-how do I know if the are any good?
I could use your services ...just not sure if I can afford them...
.... tak tomu říkám Meisterstick👏👏, super👍, zdravím z Czech Republic 🙋.
Отличное видео! Все понятно без слов, не нужны субтитры и знание языка
This seems to be a common failure on these quads, just watched another UA-camr with the same issue, granted he didn’t fabricate a brand new cam like a complete champion… this was awesome to watch
oil filter gets installed backwards, leading to oil starvation
Stunning craftsmanship Paul
Question how the hell did you cut the lower lobe on the miller?? Thats crazy. Awesome work
T - grooving cutter
@@PaulXchannel That's the part that I really wanted to see.
@@PaulXchannel that was the biggest part to leave out ):
Eccentric,off set centers or an reciprocating grinding attachment hydraulic cross slide among many other ways though this is easy to build.
@@lecnac855 couldn’t do it with an offset center. It’s not a round detail.
Nice work man. I have a guy asking me to make a cam for a Honda ATC 350. I will be looking at this for setup ideas. Thankfully hes got a place that will harden and grind it for me, because I don't have any of that machinery.
A skill that many do nor have any more. Enjoyed the video thank you,
Just loved the effect of 16:12 . It made my day happy 😁.
I'm impressed, nice work ! Can't wait to see how you'll fix the rocker arms
Great work - did you cut those profiles free hand on the milling machine? And truing those grinding wheels?
Great video! Thanks for letting us get a look.
*I like your videos, the workmanship is very detailed 👌*
So are you just manually moving the camshaft in when grinding the lobes? It looks like it and thats some nice feel you have for that process
Bonne travaille comme d'habitude. Bravo Paul !👍👍👍💯
🇮🇩CIANJUR HADIR menyimak good job 🇮🇩
Da gusto verte trabajar, muy bien
Руки из правильного места!
a video like this realy makes me wonder how such a fabrication process could ever be pofitable. so many actions
Amazing work. Just perfect.
That is some mighty fancy whittling .
Top top top top amazing job Bro
This guys is out the planet
I loved it
What is that pink grinding stone you use for the final finish on the cam lobes?
Perfeito parabéns
quite time-consuming work, but the results are really satisfying
What was the tool called that you measured the camshaft profile with?
Excelente trabajo 👌
Lindo ficou 👏🏼👏🏼
I want to know how you milled out the second cam profile seems like the first would be in the way
Did they measured the damaged camshaft and manufactured the same? How about to get the drawing fo a new and normal camshaft?
Im moving to california to be an engineer.
I am so excited to be able to afford a bigger shop for tools like yours!
Друг. Ты реально крут. Молодец.
Very interesting and I'm impressed by the attention to detail. But the trx 350 is basically a lawnmower engine in a quad and it took you about 500 hours to make the bits that you can buy off the shelf from Honda for 300 bucks. Time is money!
Amazing, this all your process? All in house?
Great job Paul 👌🏼
Awesome job but I am thinking it is so risky to overgrind into the lobes from the base diameter. Maybe not so hard to make a a shop CNC grinder that get it factory accurate.
두번째 캠은 뭐로 가공하셨나?
Amazing work Paul, felicitaciones!. I need ear that trx running. Why not show as the process of hardening?, thats is so interesting.
And how you make the second lobe of the camshaft?. Thanks!!!
If I were to do that, I'd machine the bottom lobe with a shank mounted milling cutter. Like something you'd use to cut an internal groove on a mill, just bigger and beefier. As long as you're using minimal step down, any cutter set up like a t-slot cutter would work. Can't imagine any other way, so my best guess would be he did something like that.

beatiful work, congratulations!
That was awesome man, great build
Outstanding professional work 👍
Como maquinaste la segunda leva que se encuentra en medio?
L'arbre bracame est grillée à cause du œil qui mente pas dans la culasse il faut vérifier la pompe à leile ou le filtre qui est boucher mercie pour la vidéo j'ai pris une idée pour la fabrication
Excellent interpersonal skill 👍👍👍👍👍
Awesome work i enjoyed every second.
Super super work, well done mate!
how do you do to measure and reproduce the cam´s?
How’d you cut the second lobe?? And just freehand grinding the lobes?
Great job, and maybe it would be nice to try roller bearing for rocker arm,
This is really one man army job!
Why doesn't welding the camshaft? Rocker arms welding in the last video was awesome. Is it not possible welding the camshaft too?
How did you prevent warping after hardening
Simply perfect 👏👏👏👏
все хорошо, но нужна эмульсия СОЖ, и кулачки получается на глаз шлифованы?
I'm not very good with my hands, I'm more of a head person. However, your work fascinates me and I really enjoy watching it.
How many hours did you have to spend creating the camshaft with planning and everything?
Thank you for watching.
I will show you more in the new video. . .
It will come soon.
Paul x what would u charge to make some race cams for an rs4 166
Cómo hiciste la leva de abajo . En el vídeo mostras solo la primera , y no comprendo.como haces la segunda
Was that improvised cam grinder made up from bits from an old mono-set tool grinder. Milwaukee?
Muito bom.
Parabéns.
A work of art.
Muy buen trabajo saludos
Very talent and fantastic work.
Hi very interesting thanks. I scrolled through comments so I wont ask you about cutting second cam . but would like to know details of the hardening process. I was also surprised that happened at that stage in machining. could you explain why please.
The hardening has an impact on the tolerances of the part.
That's why in most cases the part gets harden than finished to spec. The hardening goes into the surface that means even after the finish the surface stays hard.
great skills Paul
Definitely looks superior to the factory cam.
I loved your work; and subscribed.
What I wouldn’t give for the knowledge, tooling, and time it takes to do things like this.
Question. This work, great by the way, is not more expensive than buy a new camshaft?
so was it just feel that kept the right pressure of the wheel in contact with the lobe? It looked good .
Yes
How did you mill the second cam profile? Obviously it can't be done from the same orientation as the first one. Is there clearance for you to mill the second profile from the otherend, without hitting the flange?
Same question😬
T slot cutter?
🥳 🍾 🧠 👍🏆
I was looking for this comment
@@PaulXchannel it has the same marks as the first one did you use some kind of oversized stepped bit?
wow you’re skill a amazing 💪🏻💪🏻👍👍👍
