  In this paper some sufficient conditions are given for when two bounded
rank-one transformations are isomorphic or disjoint. For commensurate,
canonically bounded rank-one transformations, isomorphism and disjointness are
completely determined by simple conditions in terms of their cutting and spacer
parameters. We also obtain sufficient conditions for bounded rank-one
transformations to have minimal self-joinings. As an application, we give a
proof of Ryzhikov's theorem that totally ergodic, non-rigid, bounded rank-one
transformations have minimal self-joinings of all orders.
