Hi Steve, Thanks again for the very nice clock and great design. Here is the complete 7.5 days version. It runs well and keeps accurate time. I found that 2.8kg weight is enough for my copy to run it nicely. Personally, I prefer a little bit bigger pendulum bob on clocks that size. So, I made some modifications to support 110mm bob size. It is on the picture. I also used a wooden dowel from a local hardware store instead of a carbon arrow. I stained it with an Indian Ink (tattoo ink could work also) and finished with Blonde Shellac (from flakes). Thanks again!
