Delta 12/14 tablesaw, stub spindle threads CW or CCW

[Bill Dufour]

My Delta 12/14 Inch tablesaw came with a 1+1/8 stub spindle and several blades to match. I would like to replace it with a one inch arbor. I haver the machine taken part a good amount to change bearings etc. I can not budge the stub arbor. I think it is CCW thread just like the blade arbor threads. Before I use the impact wrench I really should know which way to rotate it to remove. I am thinking it is CW to remove which is backwards to most threads.

5/8-18 LEFT hand it is according to my shop drawings.
They can sometimes be a pain to break loose.

OP here; I got it out. It was left hand threads same as the blade nut. used my electric impact wrench. Did not work. heated up the main arbor to around 250-300F and tried again. popped out real easy. It looks like 5/8 threads
