Of course there's no way of understanding what actually went on in the design of the lobes,or how they were made. The crank looks like you had a plan and then forgot what it was. Very odd.

Amazing! I would think, though, that if I’d gone to all the trouble of doing all the design and machine work and all, I may have wanted a little more durable final product than one with a brass rod and aluminum crank. I’d want to play with that thing for the rest of my life, haha! Super-cool videos, I wish I had the ability and equipment to do things like this.

[@joepie221]

I've done eccentric crankshafts before, even posted a video on doing it, but the camshaft looks like too much fun to not try. Can you tell us how much blend filing was involved afterwards. I have to imagine some faceting was present. New subscriber too. Well done.

First of all I would like to congratulate you for being so much gifted person in this beautiful art that you do. The second thing is that I would like to ask you an advice for buying a good mini lathe good for doing milimetric revolution surfaces like the one you are using to make this video. Thank you very much if you could help me in some way. My particular doubt is if you are being able to control milimetrically the work that you are doing by the means of the hand cranks of the mini-lathe machine. Thanks a lot friend !!

That looks great actually... the crank should have some oil holes drilled through it and into bearing surface. But, are you going to anodized it? Aluminum is soft, how are you going to prevent excessive wear?

[@martinditullio1411]

Maestro!! Felicitaciones por el trabajo y el oficio demostrado

[@danielepatane3841]

Good machining but the barstock seems to be aluminum to me Is this material strong enough for a crankshaft?

[@paulluce2557]

I was thinking that as well.

[@David-yo5ws]

It's a very small single piston 4 stroke engine and will possibly just be a model running engine with no loading. I think it will be more than adequate. Also depends what it will run on. It could be an RC Model fuel with high oil content.

[@matthewbuttle]

It looked like stainless steel to me, they look very similar on the lathe Also the engine is like 0.5cc so I don’t think it’ll have torque but I suppose we’ll find out

@@matthewbuttle On the screen of my computer steel look more silverish than aluminum which is whiteish... well this is just my impression on the subject.

[@jimmyhuesandthehouserocker1069]

I would have thought aluminum too soft and weak to make a crankshaft, and how could you precision grind the journals? Unless this little engine is only for static show. I had hoped it was going to run. That was pure genius, make a camshaft on a lathe, I'm supposed to be intelligent but I could have never figured that one out.

[@johna4016]

Awesome to watch, I'm just curious about one thing: How do you know what angle to offset the intake lobe and exhaust lobe? It looks like theres about 90 degrees between them. What would happen if you offset them by say 180 degrees? And what effect would this have on the final valve train? Thanks!

[@ctrain226]

I believe and dont quote me on this, but its because of the off set of were the piston will be. Look up the Otto cycle. You have the 4 strokes intake compression combustion and exhuast but have them 180 degress wouldn't really work too well for the way the engine is running. Dont quote me on that but thats what i think. Also look up a brigs and straton camshaft

[@Alexie3333]

First you have to open the exhaust valve. Then the Intake. When closing the exhaust valve it is time to open the intake to get some scavenging (bringing more fresh air/fuel in the combustion chamber). A intake or exhaust stroke take around +- 180-260 degree crankshaft rotation. For camshaft it means it is the half of the rotation of the camshaft duo to the 2:1 gear ratio. So for example 200 degree (duration) for both intake and exhaust degree on the crankshaft means 100 degree on the camshaft. If you place bothes lobes after each other (first exhaust fully clossed then intake open) you get 200 degree total valves operation. But when valves opened max on the highest point of the cams it is 50 degree for intake and exhaust. Which means both combined is 100 degree lobe separation. So you could change the geometric of both cams (lift and duration) alone and the position of the cams (lobe separation). For more low speed engines you should have cams with more shorter valve lift and duration (the example 200 degree on the crankshaft). And for the lobe separation could be set large so the time that the exhaust and intake are both open be short. Less loss of unburned fuel. For more power and race engines the lift and duration of the cams are much larger. Here the duration could be around 300 degree camshaft rotation. This give options to open intake earlier or closing exhaust later. What called valve overlap and improve scavenging on higher rpm's. So more high speed power. .

[@nvcworld6423]

it is amazing to see how you made cam shaft on lathe ? can you make a video on that tech ?
