Well my prototype is alsmost ready for naming, also it has driven on the previous build which consisted of steel cast, wood, qbd hardened plastic material.

Less drilling, more durable con was arm angle.

My recent build with aluminium steel and tension springs only works in dry weather conditions. (more drilling less legal chancing.) I find that once the pegs come in I will be set.
It's NOT what you Can't DO Its About What YOU Can build.
