So we have challenged her to produce some bite sized bits of advice and a few months ago she wrote about the simple issue of windlasses.
Now there is a video to go with her words. The video can be found at:
She kept on using the square eye on the tapered spindle, I did manage to train her in the end, but it is a regular thing that people do. Using a square eye on a tapered spindle damages the spindles and there is plenty of evidence of this down the GU, it is also very easy for the windlass to fly off.
The eye of the windlass should always fit snugly on the spindle and NOT slip. The majority of spindles take the small tapered eye of the windlass, the exceptions are hydraulic equipment on locks and bridges, the Ham and Baker paddles on the locks between Calcutt and Knowle.
Just occasionally you may find a square spindle elsewhere. Please do not use a square eye on a tapered spindle, it is dangerous as the windlass can slip and it also damages the spindles.
