Hi Steve, first: My appologies for this late reply. Somehow the messaging system seems to have failed and you did not get the help you needed at that moment.
Looking at your sample page, I see you have tried another clock solution in the meantime.
To answer your questions as much as possible:
The clock hands cannot be larger than 100% of the clock radius. To make the minute and second hands go past the minute/hour markers, you will need to move the hour markers inward instead.
Take a look at the clock named “Mister” at the end of https://premium.status301.com/knowledge-base/coolclock/skins/ for example. There, the second hand is further out than the hour markers. Or the clock “Machine”, fifth from the top, where the minute hand is further outside.
A custom skin with these parameters might be close to what you are looking for:
