Spindle Speed Chart is in the MOLO (Manual of Lathe Operation) I suggest buying a hard copy, e-Bay perhaps $35 - $40. I see a number of versions as listed as low as $8.30 () or just google "Manual of Lathe Operation" or download from a number of sources.? There is a copy in the manuals section at . Membership required, register completely free of charge.
This copy focuses on the 12" Craftsman version but for all practical purposes 99% of the information is equally applicable to the Atlas 10" F series lathes which includes your V54.
