The Portalign is an interesting fixture. Too bad the company went out of

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
