Rabbit; Meant to as what kind of old lathe you have. I have an old South Bend engine lathe with "War Production Board" tag on it (WWII). Spindle on it has oil cups with felt wick feeders though rather than the grease cups. I got the 2" flat leather belt for it from McMaster Carr, but did a scarfed & glued joint rather than the connectors. Many old flat belts were joined by leather lacing also, have seen lots of these on old farm equipment run off a flat belt pulley on a tractor.
