Actually the chuck i used is from resurfacing disc machine that is double chuck that is not design for my homemade lathe machine thats why i make new one.
Nice I would make the angle iron 10 times thicker if I wanted higher precision. For low precision I would make it 1cm thick minimum. It has to do with how lapping paste will bend the steel with even grams of force when its this thin. When simulating a thickness to lenght ratio should be 1/4 would feel safe, 1/10 might or might not work for lapping because the stiffness is 1/10 of using the 1/4 ratio.
Шпендель на токарном станке делается из минимального количества деталей из качественной стали без сварных швов с помощью токарной и фрезерной обработки все что здесь показано все это дешовое кино
