the output shaft thread is obviously slightly damaged from the previous problems
i've used 638 on the nut
do you reckon this will be enough to hold it on?

if this holds it on and i just have to use a bit of locktite at each C&S change i'm not fussed
if i weld now its gotta be rebuilt later, which i dont really have the space or knowledge to do

ooooooh to be decisive

the problem sounds to me to be not the nut loosening, but loss of clamping presure due to wear from the roockin gof the sprocket back and forth on the shaft.
Just applying loctite to the nut will not stop this as the nut is not moving
You need to immobilze the sporcoket to prevent the wear on the clamping faces and hence loss of clamping pressure applied by the nut. This will require loctite on the splines on the shaft
