The struggle with mechanical and optical issues in most commercially available Schmidt-Cassegrain amateur telescopes is exacerbated by the random flop of the primary mirror as it progresses beyond the meridian. Several retrofit techniques are available to reduce this problem, including lock-down screws and collars. Such approaches all require some modification to the optical tube. This paper discusses "work-in-progress" on a Magnetic Loader for the popular C14 optical tube that locates a rare-earth magnetic assembly on the primary mirror collar thereby continuously loading the sleeve bearing assembly. This technique requires no machined modifications or parts, can be accomplished by removal of the secondary mirror, and requires no operator intervention during focusing. While the initial data looks favorable, additional development and testing over a wider range of conditions is necessary.
