In this video I show how i made the inlet and exhaust camshafts for my Kawasaki Z1 Super Six engine, showing a few problems that i had, and how i resolved them.
Thank you to everyone who has commented, liked and subscribed, its great to read all the comments, and i'm pleased that most people like what I do with my engines and projects, and hopefully I can inspire others to have a go in their sheds and gardens.
Yes you have inspire me, especially the flying Millyard project. I have a couple of Pratt and Whitney R1340 cylinders, need to dig them out and see if they are any good to use for a V twin engine project.
Youve inspired me already since months , thanks . Your working methodology, often ,bring me ideas to reingeneer old pieces, for an example, and much, making me dreeminh for futur builds so re-thanks
I'm stunned. If someone had said to me, "I'm going to chop up camshafts with a hand held grinder in the garden and weld the bits together again", I would of thought that's not possible. Believe in the impossible with Allen.
@Jota Rider thats why I don't want anyone around when I work. "hey you need help?" NOOOOOOO NO NOOO NO! I end up in the hospital when someone tries to help.
With great respect to my colleagues and friends (more often than not, although not always) someone coming to help turns into a bit of a training session whereby my work is slowed as we discuss what I'm doing. That being said, you can't be closed minded because every now and then someone unexpected shows up and imparts something clever and useful. Allen is brilliant, amazingly talented and creative and I have great admiration for his work. He reminds me of my father. When I reflect on what my dad created with an old AC welder, an oxy-acetylene rig, a grinder, and a vice attached to a tree stump I have to say that few are (were) his equal. He was a stunningly creative genius and apart from electronics (circuit boards and the like) he was able to create virtually anything from nearly nothing. He would have been 103 years old this fall (2020) and I expect he and Allen would have enjoyed one-another's company immensely. I remember one time asking him why my brother was stronger than me and he responded "simple, body centered cubic" At the time, I had no idea what he meant but now I appreciate his humor.
24" welded shafts to within 0.001" thats just typical of Alans site. As an engineer 40 years working in automotive and building and tuning my own engines Id have guessed "not possible" until saw it with my own eyes. True craftsman at work. Pulling the bend out with a Tig.......yep Im still learning. A pleasure to watch true skill and no BS.
I drive sporting trials and met a Scottish guy who came to see what we were up to, upon talking to him I discovered he did beach racing up near Edinburgh. He told me that they used British bikes and cut and weld the camshafts to make the engine run like a big single ie both cylinders firing together. Amazing bits of ingenuity out there.
This man really is an unbelievably talented engineer. Cutting off camshafts in his backyard, lying them on the ground and holding them in place with his foot. Result after finish: within 0.001". Unbelievable...........how does he do it? This man creates the most amazing and fantastic bikes and engines in his SHED!!! Seen a lot of his vids already but still in awe. Just amazing skills and creations, fantastic to see him at work!
I love the fact that Allen just drops the cams on the dirt in his garden, sticks a boot on one end and cuts them up!! It’s the confidence of total knowledge! Genius!! 👍
In the thinly veiled "unpack and install" sales pitches that have come to dominate RU-vid, this channel is a breath of fresh air. It doesn't appear that Mr. Millyard understands the word impossible. I'm a huge fan of this channel.
I settled down with a cup of tea to watch this with a smile on my face, looking forward to being entertained for a little while. The smile turned into a burst of laughter when Allen dropped the finely engineered shafts onto the dirt, held them down with his foot and set about them with a cutting disc. 1mm discs are indeed a godsend. The use of heat to pull something back into line is something we used to do when fabricating welded pipe assemblies - apply heat, using oxy acetylene, to the side that's proud, then either allow to cool naturally or chuck a bucket of water over it. Not as precise as Allen's method, but ok on four inch pipework. Please keep the videos coming Allen, they are a ray of light in the gloom during the current miserable situation. You should be available on prescription as a tonic.
@@lennym1273 When you melt a spot and it then cools down, it shrinks, thus shortening that side. I have been doing it for years when building frame ect. Can bash it with a hammer or just melt and cool.
Hi Matt so true!...Allen is an absolute master at what he does I do not know even 1% of what this man knows....I dont ride a motorbike and yet find these posts great viewing...Well done Allen.
first lay the parts in the sandy soil, hold with foot and cut with grinder, the wildlife is used to the noise! Brilliant unexpected simplicity of "ruski standard" engineering. Although English wizard in this case!
How could anyone vote thumbs down to this? My Dad was an engineer at Bristol Aircraft Company during WW2 and he told me he had to work to 1 thou but only seeing this video has this been put into context for me,; naturally I am proud of my Dad but frankly I am spellbound by what you are doing in your shed. As if working to such fine tolerances isn't enough you then go and conceive Frankenstein creations that many people would have been happy to buy new from motorcycle manufacturers if only they thought of them first. Bloody amazing.
What on earth !!. I would not have thought this was possible. I would struggle even getting that to spin concentrically in the lathe. Allen is the master of casual expertise .
I am the least technically/mechanically minded person in the world, but I cannot stop watching these videos. The amount of skill Allen has is unbelievable!
@@AllenMillyard I can't believe you are still using a tele 332 with dial and original cord - oh and did I mention the magic in the garage? Fantastic job!!!
I have been watching all these vids on the 6, and most parts are not that hard when one is used to welding. But It was the cams that I have been waiting with baited breath, as I was thinking, how the hell do you do them. Thank you so much for this instalment. A true master at work. Now I would love to see you make a V5 out of 2 Honda V4 750/800's. Now that would be cool.
The presentation, editing, and awesome voice of Allen means my wife just got called in to watch this video. She has negative interest in mechanical things but she enjoyed the video. I mention that he's casually doing the impossible on a rare and wonderful bike. "Hm.", she said
Finding the simplest way with what's available, not getting bogged down in the potential difficulties. Perfect, and a real life lesson on several levels
You were clearly taught well in an time when there were skilled people to teach you You are an inspiration to us all and at my age I never thought I would be able to fix a bike But I now can tackle jobs I could only have dreamt about That's all thanks to you
I love the way he never seems to bother with torque wrench settings( you want these really tight,because you dont want them coming loose) ,instead relying on years of ‘feel’ for the materials. I can totally relate,not because I wilfully ignore torque settings,but more often than not out in the field ,you just have to use what you have,and a torque wrench rarely makes an appearance outside of a workshop environment. I know many will scoff at this comment,but I’m talking about get you home measures when your in a jam,or just trying to keep the job going.
Wish Triumph had found you in the early days. No runs and no drips! Where oh where were you ? I'm placing a call to the Queen. If. John Surtees deserved Knighthood, Mr. Millyard should certainly receive the same.
Was great to see how you break down the task into easy understood bits,, loved the grinder on the grass and the barbecue so no hassle for use of the cooker in the kitchen,, and no nasty grinding grit,, ace videos thanks for sharing it with us from Northern Ireland greatly appreciated ☘️☘️☘️☘️
Well,what can you say ??? I'm in awe of this bloke.This mega talented engineering genius,is so you know laid back about what he does,so modest with it.Carry on Sir.
Gudgeon pins. Brilliant! Love the TIG truing as well: As you say, a bit of practice needed for that!!! Not kidding there!! Do you ever cook on the barbie? 😉
Some say, think outside the box. Allen sais: "Think inside box first, if it doesn't work then think outside the box." I had a broken camshaft on my prelude about 20 years ago, and took it to numerous engineers in town, all of them turn and said: "Sorry mate that can't be welded! You don't know what you are talking about." And here finally I saw Allen welding a camshaft in multiple locations. Thanks Allen! Thanks for sharing the knowledge. If only everyone would do the same, in twenty years we could travel to the moon for tea or coffee at five o clock instead of working for some change
I can’t believe what I just witnessed. Before this I watched him hacksaw two cylinder head and magically splice them all together to make a six . I’m completely stunned. Can’t say I’m ready to try this with my own Z1 though.
Just amazing to watch Allen, your approach to everything is so matter of fact, its like no one ever told you (or you didnt listen) that the things you do are difficult. Cant help wondering where we would be if everyone facing the world biggest problems had your way of thinking. Thankyou for showing what you do, sharing your knowledge and more importantly your positive atitude.
Absolute Wizardry, just beautiful work done like i have never seen or even imagined before! I wish you were just 'downt rode' to visit and get advice...excellent work Allen
What a great video, I've been waiting to see what you do for the cams, and you make it look so matter of factly simple that it looks like something anyone could do. I am amazed that you condense it down to 11 minutes, but i am addicted to watching your projects. Like the guy said, a mixture of science and magic just about covers it. Great video Allen, cheers!
So that's how you did the camshafts, I'm amazed. I really didn't think it was possible to cut and weld segments to the required degree of accuracy but you did it. Gobsmacking! Now being as you already know Henry Cole, (who gets right up my nose) surely he would be into producing a TV show featuring you and your bikes? It should be a good earner for you, just keep Henry out of shot is all I ask! You and Sam Lovegrove would make a good team.
Excellent. It will be interesting to see how the cams turn when you bolt them in place with non matching cam holders and shell bearings in place. You might need to mix and match the cam holders until they turn with no resistance. Unless you are going to machine the cam holders to match the cams? Very good as always Allen
You make all this work seem easy.. you are a great craftsman.. you know very well many techniques.. this is a great video.. thanks for sharing your work, it is unpredictable.. greetings fron Uruguay and onwards!!!..👍👌👏
I just want you to know that I hate you ..... there’s me struggling with the basics of static timing. Then there’s you building your own camshafts !!!! You are an absolute genius. I just wish I had a better understanding of engineering. Keep up the excellent work. Cannot wait to see the engine build 👍🏻👍🏻👍🏻
Your work never ceases to amaze me !! I've watched a couple of your vids lately and I'm amazed how you never seem to use a torque wrench or Loctite. I guess when you've done as many engines as you have, you've got the "muscle memory" to be able to use a ratchet instead of a torque wrench. Fair enough.....but for myself, I'd be Loctiting those cam chain sprocket bolts.......just because. LOLOL
hello Allen, I'm the guy that asked you about my XJ550RJ carb problem. I sold machine tool products for decades before retiring. I'm really impressed with how you do your problem solving not to mention your metal working skills. OK now here is my question re this topic. Do you have any concern that the difference in weight at every weld point may cause premature wear on the bushings or bearings along the camshaft ? If so, would you consider using a tool post grinder, abrasive stone, cloth backed economy roll sandpaper or such to remove some of the welding rod material to more equalise the weight from weld to weld ? That was my only concern, everything else was A1 Your videos are addictive to this back yard mechanic :)
If I remember correctly , Honda's CBX 6 had 2 piece cams ., apparently there was concern over the production straightness of the cams , due to their length . ,(I suspect the magazine guys didn't get all of the real effects Honda experienced ) ..so you've basically done what they couldn't !
Maybe. But through the 70s and 80s Honda could barely make an engine without cam / camchain / tensioner problems. And thats despite their heritage being 99% 4 strokes.
@@gs425 Yup, that kinda brings back the first attempts at double overhead cam bikes they built., not to mention the V 4 s with their strange cam disintegration .
Thanks for including the welding ground strap in the video. As if what we are witnessing isn't mind boggling enough. I was wondering. How's he grounding the welder on a spinning part? Impressive.
