Hi,
The results of your efforts look really good, you must be very pleased. You darkened the hands a bit? As the gear train has steel pivots if you make another clock you might consider fitting brass bushes that are used in clock repairing you could open the holes in the frame and either push fit or glue them in, they will wear better have less friction and oil can be used to lubricate them.
Regarding regulation personally I would not use weight to do it as more weight means more side thrust and wear on the bearings.
I would use the pendulum, as I expect you know or have found out to make the clock go faster unlike a simple pendulum where the weight is raised to achieve this on a compound pendulum the lower weight is dropped or as it has two weights lowering the upper one has the same effect. The frequency of a simple pendulum is governed by the distance from its point of suspension to the centre of its mass which for a one second pendulum is about 1 metre or 39 and a bit inches. In a compound pendulum it is the ratio of difference in weight along with their distance from the bearing that governs the frequency, there is commercially made clock with a compound pendulum that beats seconds yet it is only 100mm (4") long.
The commonest use of a compound pendulum is a metronome which has a short arm with a heavy weight below its bearing point and a light adjustable weight on a long arm above it. The higher the light weight is the slower the pendulum beats.
So if you are still awake; I would use just enough weight so the pallets clear the escape wheel by about 1 mm then add weight to either the top or bottom of the pendulum to make it go faster. When adding weight it is important that the pendulum hangs vertically when stationary to keep it on beat.
Take care Tony.
