Ok...so I have this South Bend 16 that followed me home. It had been on my radar for a few months but it took some time to come to a price that we could both be happy with. I am just going through it cleaning, lubing, and adjusting everything. It's been sitting in the corner of a shop unused for a long time. Everything is in good shape but the apron clutch is sticky and hanging up. You can feel it dragging when you manually advance the saddle with the hand wheel. So I have to remove the apron....sounds simple. Anyone who owns a South Bend probably already knows about the slotted fasteners that hold it on. I had to drill one of them on a 10L that I had. I have a set of drag link sockets but of course the small one I needed was missing. So I ordered one on Ebay. After a little time on the grinder it fit the slots nice and snug. All four broke loose without any damage. I took the apron off and decided to search for a parts diagram before I tear it apart. Any information would be appreciated. Chuck
