My first attempt to make the crankshaft from steel bar.

Hi All !
Update 2 - my V2 engine project :

Hello Minh
Nice work I like your rocker arms but just my suggestion : on the push rods you have some brass parts
//probably for setting valve clearance // do it as light as possible because heavy push rods
decrease engine performance and rise stress on cam shaft lobes.

If you could draw up some plans on how to build this, I would be interested.

Thanks for the praises !
Now, I can say: "start a new project with a design " and it could be a 2-cylinder engine with a water radiator before doing V4..., I need to learn more...

Nice job, love the V twin sound, was this totally freelance or ideas copied from something else.
Would love drawings or doodles if available. What ignition,plugs etc?

 

[minh-thanh]

Hi IC-man !
It is freelance
I combine the available things, gears, ... and the things I can do
With plugs, I make it
I can draw it before doing it, but I don't know how to do it?
I don't have much experience in machining and knowledge like some of the members here, I try to think of it as two engines but combine it with a 90-degree angle, with the camshaft I do the 4th but it seems it is incorrect, every part of it has some in the trash
