contents We show that the Feng-Xiong lower bound of $1/2$ for the box dimension of $αβ$-sets is tight. We also study how much of an $αβ$-orbit ``carries the dimension'': deleting an arbitararily small positive density set of times can cause the box dimension to drop to zero, but the Assouad dimension cannot drop below $1/4$.
