Cutting out lots of small items today. Almost finished. just the main weight and the small counter weight plus the pendulum arm remains, plus a few more holes to drill. There will also be a threaded rod on the end of the pendulum rod to make it adjustable.
The items cut today consisted of the bob components, spacers, pinion gears, escapement anchor and it rocker, the cap for the winding barrel, the ratchet gear and it’s blockers, the hour dial and lastly the tops and the bottoms for the main weight (might not be using those).
Last Items to Make
- Main weight and counter weight
The plan calls for the main weight to be a plastic tube, but I don’t like the looks of that so my plan is to glue up some solid wood pieces and turn it on the lathe. It will still be a hollow tube, but much better looking. Lead pellets are filled into the tube to give it the necessary weight, about 2.4kg or 5-1/4lb. The main weight is attached to a cord that goes around the winding barrel and the other end is attached to the counter weight which is just heavy enough to keep the cord taught. It also acts as a handle to pull down, which raises the main weight on the other end for the next 24hrs run. This replaces winding the clock with a key.
- Pendulum Rod
This is just the rod that has the pendulum bob at the bottom and a rocker attached to the escapement anchor at the top. The bob at the bottom is basically a box which will be filled with lead to give it a little extra weight.
The thin edges on the escapement gear teeth and also the tips of the escapement anchor (shown below) are very fragile and very difficult to cut so once again I angled the cuts at the tips away from the sharp edge and sanded them down afterward. This was a replacement for the first anchor on which I again had some breakout on the back bottom side of one of the points. 2nd photo below
I will probably stain the main hour dial, the pendulum rod and the clock base. I should have done the dial/gear before cutting it because it’s important to not get any stain on the inside of the teeth. Now I will have to mask off all the teeth before applying the stain.
As I mentioned before, I plan to show you all the parts in one photo and I also plan to label the different items. I’m not too sure of the proper English names of many of the components as my plan is in German. It does come with English instructions and material list, but not for the individual components. So I will have to wing it unless I can find the proper names on the net.
