    Anyone have or regularly use a Mini lathe for steel or wood?

    Yo guys, More than likely some of the older boys (naming no names) may have used a lathe once or twice, for machining little parts and bits and bobs on your home projects? Looking at broadening my horizons and add some feathers to a pretty bald cap. Cheers, HW
