No-weld PPPRS Car


The “No-weld” car project is a reference vehicle for the Power Racing Series. It is meant to serve as a blueprint for teams who want to build a vehicle but lack metalworking skills. This may include high school teams or underprivileged schools who don't have welding equipment, but do have the ability to cut and drill wood.

The concept of the “No-weld” car can still use metal, but any metal used should be able to be cut and drilled without any “special” equipment. This means that metal bandsaws and mills would be out, and hacksaws and drills would be used instead. (For our purposes we are using almost exclusively wood.)


So far we've been able to build the car body using only the following tools:

  • Table Saw
  • Drill
  • Compound Miter Saw (Optional)
  • Drill Press (Optional)
  • Hand-held Jigsaw (Maybe optional)
  • 5/8“ spade drill bit

The “Optional” tools make things easier, but are not required. The compound miter saw makes some cuts easier, but they could be done on the table saw (or with a hand saw.) The drill press makes for straighter holes, but a hand-held power drill could easily be used.


So far we've used only the following materials:

  • Plywood
  • Glue
  • Screws


Here's a quick illustration (and photo) of the body. We're using 3/4” plywood built into a torsion box. The spindles will be built using wood, and have 5/8“ hex bolts for the pivot and to hold the tires on.
