To save time in checking threads on a twenty-millimeter shell booster, a plant superintendent built this machine. It makes possible a speedy checking of thread accuracy in contrast to the old hand method. The inventor made the machine out of a fan base and a couple pieces of machine steel in a matter of hours. Months would have been necessary to buy such a machine on the market
