How is the best way to create lightening holes in the fuse when building?

Tie the fuse, and a key to the string of a kite, and wait for a storm.

But seriously, a lot would depend on what plane you're building, but basically, I would draw the outlines of the holes on one side, tack the two sides together, and cut them out on a scroll saw.

What plane is it and do you really need them? You aren't really going to take enough out of most planes to notice a difference.

The only way you will save weight is on lite ply and I use a hole saw with a hard wood back up to make smooth cuts.

I've done this with wings, and fuse by simply making a template. I opted not to use a hole saw for fear of not having a clean cut. (I used a razor knife)

When I did a sheeted foam wing, I cut/removed the sheeting and then used a heated rod to "burn" away the foam.

It depends on the tools you have available. As MinnFlyer said, a scroll saw works real well. If you have a dremel or drill press, a Roto-Zip bit will do the job, and, of course as RC Outlaw said, a hole saw works fine. You could also use Fostner bits with a drill if you have them. If worse comes to worst, a copping saw with a very fine blade would work, and last, but, not least is your trusty #11 blade (Exacto and others make saw blades for the knife, too).
