... Plates and Drilling . ... Results . ... In January of 1992 we drilled and measured a set of test plates testing several techniques including drilling with a carbide twist drill and drilling followed by reaming [R. Owen, et al., unpublished]. ... The test plates were 3.5" diameter 1/8" thick disks of aluminum. 50 holes were drilled in each test plate, 10 each in five concentric circles. ... This diameter was the optimal value for our plug plates determined from the 1/92 drilling tests. ...
