I made one of Clayton Boyer's clocks. It wasn't all that hard to cut out or even assemble but, making it keep time was an exercise in SUPER frustration!
I got it to keep good time for about 5 days and then something would go wrong. It was in my shop and I think temp. and humidity had a lot to do with it.
It was suppose to be mounted on a wall but, I tried to put it on a stand so maybe that had something to do with it.
Anyway, now it is in the basement in parts and pieces.
