Using the Weinberg-Soper formalism we construct the front-form ([ital j],0)[direct sum](0,[ital j]) spinors. Explicit expressions for the generalized Melosh transformations up to spin two are obtained. The formalism, without explicitly invoking any wave equations, reproduces the spin-1/2 front-form results of Melosh, Lepage and Brodsky, and Dziembowski.
