Sand does sound easy and more socially acceptable.
Not only that, it seems to have worked wonderfully well.
Thanks for the tip Colin, I would've never thought of that solution.
I have to say, I'm not sure how long it would have taken me to come up
with it, and I'm supposed to know about such things.
Why are you supposed to know about such things?
Because, over the years, I have done a lot of analysis of friction and
also the effects of debris and wear in what are often complicated
mechanical systems. I am even doing some at the moment.
I suppose casting defects could be an issue.
It makes me wonder how many road repairs are due to poorly built manhole
"shafts" sinking and crumbling. Winter seems to hit them badly. We should
make more use of the pavements.
