I will discuss recent and ongoing听work (with Nikolaos Kapouleas) on constructions of new embedded minimal surfaces using singular perturbation gluing methods.听 I will discuss at length doublings of the equatorial $S^2$ in $\S^3$.听 In contrast to earlier work of Kapouleas, the catenoidal bridges 听may be placed on arbitrarily many parallel circles on the base $S^2$, with the option to include the poles.听 This necessitates a detailed understanding of the linearized problem and more exacting estimates on associated linearized doubling solutions.听
