Hi
I am considering having my Super 7 reground and fitted with a new saddle but...
How can I get an indication of the condition of the spindle bearings? Is there some simple tests I can do see if they will need work? As it stands, the only practical issue I have with the machine is the ability to get a decent finish in mild steel (unknown grade) without running very slowly - bottom open speed for 1" diameter parts. I have adjusted the bed to turn accurately and a test piece shows variation of about
0.0002 over 4" which seems perfectly OK to me.The bed is a bit worn and is just about at the limits Myford suggest before a regrind is needed. The carriage tightens a bit towards the tailstock but does not jam.
So, after a regrind, just how tricky is it going to be to get the headstock back on and aligned correctly? That is the bit that really puts me off. Oh, and repainting of course - not looking forward to that.
Finally, the countershaft and spindle have been 'generously' lubricated and the pulleys and belt are very slippery. the best depth of cut I can manage in steel is about 0.040" with 0.003" feed before the belt slips. Should the pulleys be dry or are they expected to get oily? I can't really see how you avoid oil in there with everything open and all.
Any other thoughts/warnings before I start to take it all apart?
