You Got a Lathe and you haven't bored it out yet via drill bit and
boring bar
That?s the way to go bore large hole in so you can start the boring bar
then just bore it out.

Subject: [TowerTalk] Cutting Large Holes in Aluminum
I have aluminum rectangular blocks (4"x4"x1") that I need to cut a 3"
diameter hole in (using them instead of muffler clamps). I tried a
bi-metal
hole saw and also a circle cutter with not much success since I need to
make
about blocks altogether. I have a metal lathe that I can bore the
finish
diameter on but I would like to get a big chunk of the material out of
the
way (to save some time). I have also thought of using a smaller drill
bit
(1/2") and drilling a series of holes around the diameter and may do
this
but there seems like there has to be a better (less labor intensive)
way.
Thanks
