Larry, With your home brew threaded rod measuring device, how do you measure say 3 and 3/16 inches? Do you have to count every revolution from 0 to 3 and 3/16? With the high price spiffy version, there are detents at every half inch so you can quick spin to the nearest half inch then just count from there. And just count up the half inch marks to get the gross measurement.
