Hi,

I'd like to try making some simple lamps, probably using the hardware one
can find at Home Depot or Lowes. What size auger should I get? The
hardware package says it is 3/8, but it looks too small for that. Any
suggestions?


follow directions until proven wrong.........

Might want to bore a 3/8 hole and discover that's what the fittings are
threaded for. Means if you're going to take a tube threaded both ends as
your basic design, you'll want the hole 7/16 or so to allow the threads free
passage.
