Interesting stuff, we'll have to look into it.
Back to the Quick Affordable Wood Chassis....Gary finally came home and made a sample cantilevered dead axle. Yeah, it's pretty simple, a dollar and a half for a bolt, hacksaw the head off, drill a 1/8" hole for a cotter pin to retain the wheel.
Hopefully he'll get some Inventor work done and show us what the chassis with the axles and Toughboxes could look like.
