Double pendula compound grasshopper escapement

Hi Art
This clock is my most recent one and demanded some new challenges for me. The designer is from Germany and the materials he called for are not easily available here is Canada. Since the plans were dfx a quite a lot of reverse engineering was called for.
Here is a photo of the end result - the ...

Re: Bearings in clocks

I’ve just completed David Atkinson’s Sextus design and it is the first clock that I installed steel bearings. Although David has bearings in several locations I only installed them on the pendula. Since the escapement is a grasshopper type it is highly sensitive to the drive weight to regulate the ...

Currently I am making cages the ...

The wood is a souvenir from an trip we made to Mexico (the wood is actually from Brazil or Argentina) anyway I liked the look of it and though of using is for a skeleton clock frame.
