Alright folks, not your usual build -
For sale is a copy of the book chassis in 5/8 scale (62.5% scale for those who prefer this sort of math).
The chassis was built mainly for me to test some theories I had as well as to practice my welding skills and practice some more before I'm starting the full scale build.
The frame was built using scale correct 5/8" square tubes, thickness was retained at 16 ga.
Rear shock towers and base plates for rollbar are made of 1/8" thickness for added strength, rollbar iteslf is made of 1.25" round tube al 1/8" thickness as well (definately an overkill).
The welding quality is good for the most, a few of the welds aren't too pretty and you would probably want to grind them down and re-do them.
The chassis is straight, maybe not 100% by aerospace standards but definately straight for what it's supposed to be !
It is almost fully welded.
You can make this into an awesome toy for a kid, I measured my 9 y.o. skinny and a bit tall for his age nephew and this chassis will be good enough to fit two of him with a narrow transmission tunnel.
The transmission tunnel structure itself was left out so it can be built around which ever motor you're going with.
You can easily adapt a small ATV / lawnmower / go kart / bike motor and run a chain to the back to make the transmission tunnel as narrow as possible.
Another option is to make it a single seater adult go kart and just stick a bike motor in the back over the axle.
Overall length is about 6'2", width is around 27" and height at the top of the rollbar is about 29".
It weighs ~41 lbs on my bathroom scale.
