this is going to be good!

If only i would have taken my high school welding class seriously....

kamlung

want to do another set for me once you are done?

that looks great

That's pretty cool - like the mig (tig?) too, along with your welding table - very nice.

Does CREO allow for the printed copies to outline exactly where the cuts will go? I think that would make life way easier if you could simply put an outline down and use a nibbler to take out the excess metal. I'm not familiar with Pro Engineer, but those tubes look pretty spot on.

My CAD version does not match the Cardboard CAD. I am building from the cardboard cad version. When i am done i will probably update the cad version and I can use the shape of the 2 1/2" S bend tube as a sweep cut to make the 3" tube have the exact shape of the interface. If i ever were to make these i would have the 2 1/2" S bend tubes formed from one piece and then have the 3" elbows cut to match with a 2 1/2 R cutter sweeping the path of the s bend tube. It would be fairly involved to set it up but once it was done they could pop these things out. To be cost effective it think i would need to build min qty of 25 min to be cost effective on the setup.

When i retire in 3-5 years i may start making stuff like this. Right now nobody could afford for me to make these. I design stuff kink of like this for vacuum chambers. If i designed this for work and sent it out to have one set built here in Silicon Valley they would be about $500 each $1K for a set, any takers?

I want to see the end product now...

Getting closer

i like it!

Looking good!

Great project, looking forward to seeing the final product on the car.

kamlung

i need to learn how to weld... that's a beaut

He is using a TIG (tungsten inert gas) welder and can stitch the pieces together very neatly as he doesn't burn through the metal as say a MIG (could) may when using smaller gauge material.

Once you have a basic understanding of how not to burn holes through your material, it is a very elegant way to piece together SS exhausts.

You should get one.

This is the welder i bought. Did some research and it has all the advanced features at a good price and parts and repair are supposed to be available.

Yeah that's neat - are you using a gas (argon if memory serves) to shield?

Third-Reef

Yes Ar is required for TIG even on mild steel. It will do stick welding also. The flux on a stick welding rod provides the shield gas. TIG for Porsche projects, Stick welding for tractor projects.

Cool project!

Are you using argon as a sheilding gas on the inside as well?

I'm going to be adding some 6" magnaflow mufflers with v-bands in the location of stock cats for my 3" x-pipe exhaust so that I can swap out between a loud and less loud option. I've got most everything in, and done a fair bit of mig welding, but haven't tried my luck at Tig yet, this will be my first project but I read about the need to use argon on the inside to sheild the wed and purge any atmosphere gas in that area when wleding 304SS.

Anyhow, keep up the good work and nice job thinking outside of the box.
