Cross thread.

11°C light rain under grey sky.
It should have been a simple job.
For a few weeks a cracking noise came from the Arrow’s bottom bracket. This has happened before when warm weather started. It’s as if the warmer, expanded metal gap loosened the lock-rings.
It should have taken an hour to fix it. It took over two.
The threads were stripped on the left side. That is a worrying sign of possible damage to the threads in the frame; a job for a frame builder.
Eventually, I got it out, cleaned the inside threads with a wire brush and got swarf in my finger.
It’s done now, but to play safe, I have a new bearing on order.
