Desert Dynamics Sand Car - Backhalf Rebuild

Nice work as always! Do you have a plasma table?

No, I have 2 Hypertherm manual plasmas (a 380 and a 1000) but I had Cody at So Cal Plasma Craft do the cutting for me on his CNC table. Great guy to deal with all around.

Looks terrible...were you blindfolded when you welded that contraption?


OK.... as always, excellent work, looks even better as a "real-world" part! Now he'll probably want you to keep working forward.

No blindfold but I must have got something in my eye while griding.

Thanks Steve.

Paul, did you clamp that part to the table when welding? I noticed the bracing... but how did you keep the whole thing from warping?

No, I "free-air" welded it and staggered the welding to avoid warpage. The bracing kept the ends from wanting to pull in with the weld shrinkage.

I hate you. For real. Super clean!

Wow man. That looks awesome. Its funny how much cooler a part can look when plate is used in place of tube.

So is the car square? The last DD car I worked on was 1-3/4" out measuring diagonally from the floor bars to the roof bars at the C pillar.

It's not quite as bad as the one you worked on but it is definitely not square.

I set a reference plane on the lower frame rails just ahead of the torsion tube and I had to spend a good amount of time taking and verifying measurements for layout.

The front of this car looks like it was assembled by a kindergartner.

Plated in the front of the chassis and added a double shear plate for the upper a-arms.

These cars have been known to rip the bungs out of the top tube.

Also plated in the lower portion of the frame and added a captive nut as the skid plate comes all the way to the front but the last few inches had no mount and it already folded under once.

Still need to add some gussets for the rack mount.

You no like trigger weld?..............

Boxed A-arms or the stupid mohawks?

LOL, Ricky-Ticky-Tacky behind the gun is a problem with the whole car.

...the front end of this one must have been layed out by the same guy that did the one you worked on. Mid-rails are off-level by .500" at the front, the dash cross bar is higher on the driver side by .750", the rack mount is crooked, etc...

And he runs the "mohawk" arms.

Nice, I'll have to come by and check it out.
