I've also got to decide what to do with a dead clock. It's currently sitting on my bench as a pile of pieces - I stripped it down to component parts to clean it. Now I need to decide whether to spend money on it and turn it into a functioning clock (it will need $16 for two new springs, about $4 for hands, maybe another $20 for a dial, potentially more if I want to put a glass on it, a pendulum and a case). I can probably build the case as a learning exercise, maybe even source some ground flat stock and make the hands (slow and laborious but a good learning exercise) but the glass and springs I'd need to buy. I'm not sure whether to spend the money on it and hope to sell the finished clock and recover the money, or turn the parts into a concept clock, or just chuck all the wheels in a box of spare parts and use it to repair something else later.
