A construction is presented which, given a fixed undirected graph of low degree and small average path length, yields an infinite sequence of low diameter graphs of increasing order and fixed degree. As examples of the construction, infinite sequences of low diameter graphs are presented with degrees in the range 3 to 30. Expressed as a function of the order of the graphs, the degree 3 sequence has diameter bounded above by 1.4722 log2 N + O(1), and the degree 4 sequence by 0.9083 log2N + O(1).
