Hello, Im designing exhaust piping for production,, and I'm using Another method for this type of work.. It's much easier than 3d sketch.. Im creating one component for strait pipes, and second component for elbows / bends, with simple 2D Sketch... Then I'll make copies of what I need, straight or bend.. simply joining them together with "Joins"... Now You can simply enlarge straights, or make changes to elbows, just simply editing 2D Sketch with dimension.. and for rotation You can use position in joins 'settings'.... Simply put,, create straight, and bend parts,, and simply join them together
Yes, but keep each pipe/elbow as separate components, copy/paste_new command, then you can adjust sweep angle or length of pipe in each component sketch, or from the parameter window. That way, you build the manifold almost as you would in real life, with tag welding and adjustments.
This is definitely going in my favorite videos list. I’ve been pondering about making an intake manifold for a 2.4L Dodge engine. I could be dreaming, but I was thinking about using single barrel intakes. One for each cylinder.
I did an intake set of videos awhile back ru-vid.com/group/PLBDfGh8A8kXXkrW-pb6JpzxdqjLW4IFBc that has a few options on ways to model. As for the single barrel intakes, that really depends. Its a game of either high rpm flow or volume depending on your application. For example you see high revving engines being able to use short runners and individual throttle bodies and it works ok. In most cases you want a reasonable size plenum for a turbo application so there is enough volume to fill the cylinders. the "cannon" intakes are pretty common and generally easier to fabricate, but if you are staying NA then who knows :)
Yeah.... I did start the video warning it was painful :) 3d sketching anything other than straight lines along XYZ or doing a 3d spline with references is very tough to control. I certainly prefer the straight line and fillet method and just buy some bulk prebent sections of tubing.
Hi Matt you forgot one other method. You can 3d print the manifold. Probably nobody has a SLS metal printer but online are a lot of solutions available to do the work for you. Just to complete your always great videos 👍👍👍👍👍👍👍
I can only imagine the cost of that :) Years ago i saw a beautiful intake on a datsun forum where they CNC milled the top and bottom for a 240z and welded them together. It was a work of art but the Billet to machine each piece must have been $$$
@@LearnEverythingAboutDesign Agree it will cost a lot, still it’s an option and in some cases you need the flexibility. I guess this will mostly used in racing cars where is a high budget. But why not try it, you have a nice STL file, ask a free quote at PCBway (for example). Don’t understand me wrong, my input was only to complete your story. In no way I meant any criticism, I love your work on youtube
@@Eric1960 No worries I didn't take it as a negative :) but thank you! There have been some high end super/hyper cars that have done 3d printed inconel exhaust components for things like heat shields/pass thoughts on hoods and firewalls.
As always, thank you for the great videos. I always learn a trick or too from each video. I may have asked this before on a previous video, but how would you create a dimensioned drawing from a model like this? How would you show the angle of each bent section? How would you communicate the angular rotation to adjust the out of plane bends? While it is super cool for us to be able to design and visualize parts and assemblies, but if we can produce a documents, or other build instructions, these cool models and renderings are useless. I have used a combination of AutoCAD, Fusion, and a software similar to Bend-Tech to build a header, but I'd really like to figure out how to do it all in a single program, especially if that program is Fusion.
yeah that is a tough one for sure making a drawing for something like this. So if you were using say bend-tech often times the entire primary is a single pipe that gets rotated and bent and its figured out from a step file/3d model. For something like this if you needed to make a drawing in say Solidworks you can import annotations from the sketches and include them in the drawings. So if you did the first arc out of the head plate and rotated it 30deg toward the front of the engine then you could have that dimension imported. Sketches in fusion drawings doesn't really work so great and you can't bring 3d sketches into a drawing unfortunately. So i don't really have a great answer for that other than manually recording the bends, angles, and lengths from your 3d sketch and doing a generic table in the drawing to capture that info. I wish I had a better solution. IF your 3d pipe runs were defined by projected 2d sketches you might be able to get away with that by showing sketches in the drawing....might...
If you end up printing something you can get away with way cooler shapes and non round cross sections! I have never welded 3d printed metal before. I have soldered to it before though. I wonder how welding would work.
@@LearnEverythingAboutDesign Complete disagree with OP comment, the tangents are where real learning happens for me, but it's just really hard to index the videos based off of that from a learning standpoint. But again, the tangents are super helpful for advanced learners
