Team 449 competed in Trenton last week and we felt we did pretty well, but one of our hubs kept coming loose. The hub connected to an arm of our forklift, so the 5 or so degrees it could move let the end of the arm move several inches. We use AndyMark 500 series hubs which we have drilled and tapped for 8-32 set screws on a 1/2 inch keyed shaft. We tried tightening and applying lock-tite several times, but one hub kept coming loose after every match. Does anyone know a good way to get those hubs to stay tight or know where we can buy better hubs that are still light? Thanks.
