We study families of metrics on the cobordisms that underlie the differentialmaps in Bloom's monopole Floer spectral sequence, a spectral sequence for linksin $S^3$ whose $E^2$ is the Khovanov homology of the link, and which abuts tothe monopole Floer homology of the double branched cover of the link.  The higher differentials in the spectral sequence count parametrized modulispaces of solutions to Seiberg-Witten equations, parametrized over a family ofmetrics with asymptotic behaviour corresponding to a configuration of unlinkswith 1-handle attachments. For a class of configurations, we construct familiesof metrics with the prescribed behaviour, such that each metric therein haspositive scalar curvature. The positive scalar curvature implies that there areno irreducible solutions to the Seiberg-Witten equations and thus, when thespectral sequences are computed with these families of metrics, only reduciblesolutions must be counted.  The class of configurations for which we construct these families of metricsincludes all configurations that go into the spectral sequence for $T(2,n)$torus knots, and all configurations that involve exactly two 1-handleattachments.
