I have recently bought a Myford Super 7; it is in great condition. I have stripped and reassembled it. My problem is that when I can a cut in mild steel I end up with ridges in the metal. I have tried varying the speed of cut, depth, cutter type, height etc to no avail. I have machined a piece of brass but without the same problem. I have adjusted the saddle and the cross slide so that they move more freely. The is no placy in the saddle or the headstock bearing.
Anyone any ideas.
