Any suggestions on how to mount this clock using only a single mounting point?
It has a pendulum so it needs to be relatively level. I tried to run a piece of wire between the holes hoping to fish a piece of string or something to create a triangle for mounting but no such luck.
No such luck was i was not able to get the wire from one home too the other.
And as far as two screws is i am using mounting hooks as they only make a very small hole in drywall rather than two big holes for screws and drywall mounts.
Okay so you use (2) of those things. Do you have a level? If so put the level on the back of the clock over the mounting holes but where you can still see them. With a pencil mark the level where the mounting are. Now you have a template/ measurements for the mounting holes on a level. Now take that level and hold it on the wall where you want to mount it. Hold it level. Find your two marks and mark the wall in those locations. Now insert your little pokey hooks in the wall and hang.
Well, with wire, you can thread it through the holes and then wrap it around itself.
But here's an alternative. Get a couple of pictures hooks, something like this . Tie one onto each end of a piece of string or wire. Put the hooks into the holes on your clock, then hang out over the thing on the wall.
