I have printed several of Steve's clocks already. All of them have come out great. Decided to try the desk pendulum clock and am going crazy trying to set it. I have tried endless combinations of the Active and Static pawls. Its always the same result. No matter what I do I get a few single space clicks on the ratchet then double space clicks from that point on no matter what I do. I even tried creating what I call a Metal Hammers that's attach through the end of the pawl just to add a little more weight to the pawl. I would always make them for all the wooden clocks I used to make. I tried this on the first SP7 clock. I put the hammers on both the active and especially the static pawl to stop the static pawl dead in its tracks to stop completely the slight backward motion of the second hand. Im still adjusting the time on the first clock as it is still running slow. So moving the bob ever so little to get it perfect. But the second SP7 clock just will not work with anything. I have spent now 5 straight days trying from morning til night to get the double ticks to stop. I'm trying to hold back from finding my sledge hammer and put the clock out of its misery along with mine..... Any advise Steve??

I had this issue when I built this clock too.
Firstly, make sure your second hand was printed solid (100% infill or the preimiters that steve mentions), being counter balanced stops the double clicks if the second hand is heavy on one side.
I didn't realise this until I started building my second version, and I fixed it by glueing a small 10x4mm magnet on the top of static pawl, which added just enough pressure to stop the free movement of the cog from double clicking.
