Floor pump came apart , Serfas FP-50
My floor pump came off its base yesterday. The screws that held the base to the shaft had never been screwed into their holes. The base has 3 pairs of holes, not symmetric with the shaft - the shaft had been installed backwards; the screws had a little purchase against the side of the shaft. I'm surprised it held so long.
