sir while using my master 2500 this afternoon i stopped the chuck via the clutch, all of a sudden about 2 table spoons of oil gushed out from behind the chuck and i could hear oil dripping down what i think is the oil return pipe, is it possible for this pipe to get blocked and fill the head stock to the brim? from memory i think the pipe is a large bore and it cannot be seen when looking in with the top removed, tomorrow i will remove the top but the oil may have seeped back into the tank below, has any one else ever had this happen? thanks fodenman
