I'm working on a design that requires threaded shafts and wants to use ball bearings that would typically be press fit on a precision shaft. The shafts are made from fully threaded studs (.5") and measure about .492. This project is for a low speed application (10-100 RPM's) with no great precision required. I've seen some use jam nuts and threadlocker to secure bearings for this type of DIY work, but the jam nuts would take up needed space in my design. I'm wondering about using thread locker under and over brass shim stock (.002) to get better concentricity. I've made a prototype using this construction and it seems to work well, but reaching out here for caveats from those who might have more knowledge and experience. My aim here is a salable kit, and price point is critical, but I don't want to sell something that will fall apart.
Thanks!
