I've fairly new to metal machining. Almost 2 months ago I got a Sieg C3 7x14. I made a few simple projects, but am trying to pause and tune/align the late going forward. I've done a handful of basic housekeeping adjusting the gibs, backlash, etc.
Next on my agenda was check the head stock alignment to the ways. I'm using the Rollie Dad's method of measuring and am finding 0.00275" horizontal misalignment over 5 inches using a MT3 taper bar in the spindle.
Does anyone have experience adjust the headstock? It looks like this is keyed with V-channel and held over the ways with M8 screws at each corner. These seem awfully burried. Is the best way to get to them to take the motor out?
And it looks like the only way to adjust would be with shims? I've read general advice to be really sure you need to adjust the head stock before you adjust it. I can put a MT3 to MT2 bar in to my tailstock and have virtually 0 variance from headstock end to tail stock end. But if I leave it this way, the tail stock doesn't drill centered. It hits slight away from me in the center line.
Any thoughts or suggestions?
