intake manifold plans
(OP)
I'm looking for plans for a short block chevy intake manifold. I want to build one up in Solidworks to improve my skills and to have something precise on my resume. I also have a friend that will machine it for me so I can test it and add the testing to my resume. (This will be done at a Technical college in my town).
Can anyone help me with this or have any suggestions?
Thanks

RE: intake manifold plans
I am concerned about the dimensional error that will come in with standard measuring using calipers and such. I have seen some manifold designs with vortexes on a curve. I'm not sure I can measure that properly off of a part that has been sliced. I think I would lose too much at the cut site.
I will have the part in hand, as you suggest, but I believe I would create a better file with the drawings- at least until I have more skill with this type of product.
Thank you
RE: intake manifold plans
Then take a compass protractor scale and what ever else you can use to put the slices into the sketch mode of a solid.
At that you take some artistic license to fair in the slices either curve to curve to create a surf or modify the solid body's to union them. Sorry this lingo is in CATIA but you get the idea.
My latest is a Norton motorcycle head which is now cut in halve (mirror) and is off to a real machine shop to cut into 1/4" slices. This will leave me the other half to obtain any missing data from the overall picture..
The final product will be an SLA then an investment casting

RE: intake manifold plans
Vortexes etc are normally only on aftermarket manifolds, and are just marketing spin.
The main parameters are packaging, port alignment, airflow, taper and cross sectional area.
Reasonably concentric radii of turns in the runner and good finish on the outside curve helps. Finish on inside rad is not critical and is therefore subject to marketing spin as visual alterations for marketing only do least damage there

RE: intake manifold plans
That is to use the gasket dimensions to create your flanges and position them in space relative to the carb/intake flange.
So now you have the begging and end of each runner.
To obtain the runner configurations use the existing manifold and fill each runner with silicon cast. Use this to slice up always normal to contour.
This will allow you to use crv to crv to generate a surf. Now use thick surface to put a desirable wall thickness outward and it will start to look like an intake manifold....

If you knew the industry, you would know that calipers are not the way to dimensionally inspect precision parts.
Sorry to sound so coarse. Like the other guy said, too many ill prepared folks.
RE: intake manifold plans
Precision numbers are the only way to go. Even making blow-molded bottle designs, like I do now, is too imprecise for me. I like tolerance studies on tight tolerances.

"Work with machinist" You need to give it a try yourself, and not just the fun stuff. You should get to enjoy (sarcasticly) the frustrations of that job. The constant fight to maintain tolerances, finishes etc.
And honestly how many times does the machinist actually do the engineering for you? Or if it is a setting like say prototype engine work, how many times is it the assembly/builder/tech that is the real engineer in the project and finalizes the useable design, and of course never gets the recognition for his work.

You want salt and vinegar on your shoulder?
Because that chip's looking a bit unappetising.

These things are best solved by mutual respect and consultation rather than by only considering one point of view. Chips on shoulders do not help this process at all.

RE: intake manifold plans
We're all specialists in one form or another, but we become better worker bees the more we understand the details of other specialist's jobs. I have spent a great deal of time understanding the PC board manufacturing process so I can anticipate where my design might be changed on the factory floor... in return, I expect the manufacturer to know enough about my job not to change something critical. It's called experience, we all get it in one form or another, be it from a mentor or failed projects.
If the engineer was required to understand it all, though, there would be no reason to hire anything more than a monkey to run the mills, no?

But I think we all agree there is a deference between design and engineering.. I have yet had a machinist or mechanic re-engineer something for me....
