Using my previous paper for marking a cut line, remove paper from tubing ande 
flatten it out making a crease in the paper.  Each crease is 180 degrees from 
the other.   result a NO measurement method of finding opposing holes for drill 
in round stock material. Just slide the pper back over the tubing and mark the 
tubing at the crease.  All this takes is paper, some Scotch tape, and a pencil.

For small tubing a "PORTA-LIGN fixture on a hand drill will provide a good thru 
hole.  Used this method to make 4X14el 2M yagis and 8X16el 432MHz yagis.
