Project SC300 Road Racer: Part 27 – Joining a Wang Gang

  • Erik Jacobs
man in welding gear illuminated by weld arc
Johnny is very careful not to overheat the wing when welding it. Since this is all aluminum, heat management is critical.

One side of each tab is welded, then the whole assembly is allowed to rest and slowly cool, and then the other side is welded to finish the job. Sometimes you just have to deal with shrinkage appropriately.

 

three clean welds attaching the mounting plate to the wing body
Johnny stacked some TIG dimes nicely.

 

the letters s-c-3-0-0 etched into the metal of the pylon
Aww isn’t that cute. The car model is CNC’d directly into the pylon!

I love attention to detail…

 

two black powdercoated pylons laying on table
Here are my two pylons, powder coated a nice matte black after the tabs are welded on.

An interesting design detail – the tab is slotted to receive the pylon and then the whole thing is welded together.

This makes welding a lot easier as you are not trying to deal with beveling two 90-degree mating surfaces and then holding them in place at a perfect angle.

    “But there’s an end to this means, I assure you. And it’s not another innuendo. I don’t think. If you look back to the photo of Rob, he’s taking a photo. In fact, he’s taking dozens of photos. You see, when you take dozens of photos from different angles of the speckled car, you can then use some really fancy computering to stitch all of the photos together to build a really accurate 3D model of the vehicle.”

    Rob is using a regular digital camera and then stitching 2D photos together using software to build the 3D model.
