Modelled the TS exhaust manifold... It's not perfect but close. Next I need to borrow a head :lol:

Was just teaching myself some new tricks in CAD (how to 3D sweep and use Loft)...

Nice! Of course they had to be rusty and old

Wouldn't be an alfa without a little corrosion :cheese:

That's brilliant..how do you do it..laser scan or something??

 

[Turtle4288]

I wish! One of those gizmos is about 2 grand. No, I just used best guesses until it matched the real thing.

 

[seadart]

what you drew it by hand on autocad??

 

[Turtle4288]

Solidworks, yes. Its fairly easy . A lot harder to do the next bit.

2nd engine part

Crankshaft... quite accurate, had to guess the throw length (distance from centreline of crank to centreline of big ends...

Anyone know this dimension?

 

[Turtle4288]

Stupid question of the day above....

Crank throw is half of stroke, obviously. So 45.5mm
