Avril, found a fancy outdoor battery clock, dumped, and took rather a fancy to having it in the garden. It fired up straight away on a new battery, but kept stopping which I worked out, was due to poor alignment of the hands. I sorted that, and ready to seal it back up, I dropped the glass lens, and broke it. I found some suitable thin plexiglass in the workshop, but every attempt to cut it into a circle, caused it to shatter. I tried jigsaws, various blades, handsaws, hacksaws, even fret saws. Nothing worked, without shattering the plexiglass. I even tried researching how on the internet, all said just use a fine blade..
Then I got the bright idea, of roughing it out, with a thin cutting blade in the grinder, finishing off with tidying the edge on the bench grinder, which worked a treat
