Aluminium or Steel ??

okay, i know, i have the possibilities, the skills and the machines to fabricate both versions of a center foot for my R2.

but i am still sure, that the steel version is much more rigid than the aluminium version.

but because i am not intending to drive against a wall or other hard objects that might destroy my work, i let cut a set of both versions.

the steel center foot has 1 mm material thickness...

pic will follow

the aluminium center foot has 1,5 mm.

pic will follow

so 50% more thickness means, to have almost the same strength in the material... almost...

let´s see about the weight of the parts...
