I am planning to buy a clock movement test stand and have seen quite a variety. I am wondering if there are reasons or advantages to buy one type over another? I am working on all different types of brass movements (Ansonia, Newhaven, Gilbert, Seth Thomas, etc.) large and small. If possible, I would prefer to buy only one or two to serve for all kinds, instead of one for each and every type. I am also starting to work on tall case clocks and was wondering what works best for these?
