I wanted to know what style of chain bar people preferred as in 180 chain bars or chains that has the stack of cones go through its center
Can you draw a pic or reference some youtube videos? Not sure exactly what you mean.
Take a look at 1045A’s robot. I think they have the type of chain bar you’re looking for. As for how to build them, take a look at Griffin Tabor’s video on it
Or the O.G. ALBA reveal of OSIZR!
Think he is referring to external stacker and internal stacker.
