This mower has several cross bars with 3/8 or ½” BSW threaded ends. Inevitably over 80 years the exposed ends of these bars have taken a few knocks causing damage to the thread especially the bar through the front rollers. The new brass nuts I’ll be using can be screwed on with some effort but being a softer metal than the steel bar this can causes cross threading in the nut so this week I’ve been grinding down the ends of the bars just sufficient to reach clean thread. The nuts now spin on with ease.
