Hello all, new here, I have craftsman 109 that I have restored and I am well aware of the limitations of these machines. It is mechanically sound, I feel it is close/good tolerances for for this type of machine. My question is what type of material should I use to make some "practice" cuts to further dial this thing in along with my bit grinding skills. I have been using some cold rolled w/ hss bits but I think my end results could be better. I know these are not the best machines and I would upgrade once I find something, but in the meantime its all I got to learn the lathe a bit better, thanks!
