I am trying to get my head round a 3D model and I am going to admit defeat. Can anyone do a quick 3D model (DXF probably) so that I can get my inlet manifold machined?

Basically I need a blend between a 50mm round inlet to twin 35+33mm outlets, over a distance of about 70mm.

I have Corel Draw so can export in whatever you need to get started. Any help would be appreciated - it seems I am only ok with 2 dimensions

How far apart are the centres of the 33mm & 35mm ports ?

My weapon of choice is Autocad with Xtube.


Maybe one of the solidworks experts could also help out with this.

Here's a pic of the 2D file


LIM & Trumpet

Looks like some of the dimensions didn't make it - I already have the trumpets so the blend is the only thing left to do. I can then duplicate it and paste it onto my baseplate ..... all in theory of course

Here's another pic if its any help

What software are you using?
I've drawn something, not sure if it's what you're after.
If you PM me email address i'll send some pics and a quick description.

Deleted mine because it was rubbish compared to the one below.

Description

inlet thingy bottom

inlet thingy top

That's much more like it.

Well done sir.

Bloomin' heck! I've been messing about for hours and you come up with EXACTLY what I am after in a few minutes!

U2U coming your way

LOL
It's only easy if you know how.
Simply, loft the out side, then two lofted cuts for the runners.
Play around with the constraints and such until it is's right.

The wall is 3mm at entry and exit.

Are you after some sort of flange to join to the head?

I'd prefere not to give you a model that you use, as if it's not right you won't be happy, and i'm guessing it's not cheap tp get one made. Also, my skills fall a little short in terms of CIM.

I'm more than happy to give you/anyone the model, and i don't mind if you do use it, as long as you understand it took about 5 mins with very little consideration.

I'll give it another look, might be able to do a little CFD if i get chance (probs not today as i've got something important on Monday) although there's very little such a simple design could be improved.

Holy crap!

I am not sure what thickness the baseplate needs to be - 6mm? 10mm maybe?
