I needed to get the SG up and running to get some simple jobs done.
I figure I will learn a lot just using it, perfection can come later.
The table was tested as Ok with the DTI, the chuck cleaned like the table, and the chuck mounted not too tightly.
The wheel is 38A60-J, 162x11 mm, used without coolant at 2950 RPM.
Small sample pieces of MS and CI gave a reasonable finish resulting in <0.01 over 80x30 mm.
Very pleased with progress so far.
I am sure the only reasonable finish is due to my lack of experience.
Coolant is next to be introduced, and experiments with a coarser wheel and various speeds (VFD).
Testing surface plates against the straight edge should start in a couple of weeks.
