Sounds like you would be a good candidate for a holesaw style notcher.
Has anybody tried TWITS (thin wall independent tube support)? They look like they would work well for clamping down thin wall tubing. I dont have the fancy notcher they are selling, but it looks like it is made to work in my cheapy notcher too.
I'm coming from a metal fab background (Bicycle Framebuilding..) and I'm also kind of a computer geek. I just completed an upgrade to the tube miter / tube notcher software. Obviously not the quickest solution if you have a zillion notches to cut.. but this may be of interest. Input key dimensions, calculate, output to a full size paper template from your printer. (alternate = .dxf output to your CAD system..) Cut out the pattern, tape it to your tube (careful! get the reference lines right for orientation and length!) Mark your tube with a felt tip pen, cut / file steel to fit. Done! I've added lots of features to ensure high accuracy.. alignment marks, measured references, etc.. Program includes tubular braces / gussets, offsets and partial interface outputs.

Oh, cost = free. No special tools to buy (tube holders, and a varied set of half round files, and I suspect you've probably already got that stuff..) The software works in your browser. Instructions / Java tester here.
Sample output, offset set tube:
One thing.. are there any joints in the home built airplane arena that could really use an enhancement? Are there any special joints that are difficult to development where an accurate flat pattern would be doggone helpful? I don't mind updating software where it makes sense.
This is super cool...I will be using this in the construction of my F1 raceplane...
That is cool!
Check out our new offering for notching on a bend. Should be a good fit for the airplane crowd
What about adding one of these to your existing tube notcher and save a few bucks? Looks interesting.

where can I get it?
