Build Notes

Frame and Chassis

Frame mockup

This powerwheels seemed to be an older vintage as the frame's cross members and steering assembly are made of 3/4" steel tubing. Finding this was a pleasant surprise. We decided to keep the existing frame and steering geometry intact and simply build off of it. We discovered that the front and rear cross members are not on the same plane (different elevations) due to the steering linkage and we couldn't figure out how to measure their positions as they are bolted to the car's plastic frame. Instead we bought about $5 worth of half inch PVC to mock up a frame and build around the body attempting to minimize any cutting into it. This allowed us to better visualize what we needed and plan for cuts, weld preps, etc.

Frame fabrication

We elected to go with 1/2" square tubing on the frame, because weight. Some of us tried some back of the envelope beam stress calculations to size the tubing and figured that 1/2" tube wouldn't cut it. But in the end decided to go with it and just repair and reinforce if anything breaks or yields. Several people got a chance to develop welding skills on this. A few kids got a chance to observe as well. We used a cheapo FCAW 110 V Welding Machine from Harbor Freight that seemed to be good enough for this job.
