My apologies in advance if this post seems all too familiar but I just could not find a solution to my problem in previous postings.
Background is I am refurbishing my 1950's-vintage 13" x 6' SB lathe. Got through the reversing gear system (seized bearing) and refurbished the QCGB; am presently working on the apron. I am using the ILION Refurbishment Guide that does have some pretty good guidelines and photographs.
My SB lathe has the star knob configuration for the clutch, but it does not have the center screw, the one that has left-hand threads, so there's the first apparent difference. The star knob freely spins off to reveal the shaft and hex nut that secures the shaft to the apron.
However, there is a special nut inside the hex nut that appears to require a special tool to remove it. That is the second difference from other descriptions. In fact, the ILION guide makes no mention whatsoever of this feature and merely states to 'grasp the clutch gear and loosen the hex nut.' or words to that effect. I may have overlooked the obvious but it seems to me there really is nothing to grab onto that will keep the clutch assembly from turning.
I've read other posts that imply a special bushing or similar adapter might be used beneath the star knob to lock down the shaft and I can kind of see that as an approach, but what of the special nut inside the hex nut? I don't understand how that factors into this configuration. And with there being no description in the manual/guide I am at a loss.
