Builder Tip #88 from HomebuiltHELP 
3 Tools for making Lightening Hole Flanges
Wing ribs and spars throughout the aircraft have lots of lightening holes that need flanges
If you are plans building a metal aircraft, you are aware of the need to flange those large lightening holes found in many components within the skeletal structure of the aircraft. The tools for creating these flanges range from the simple to the specialized.

This week's Tip demonstrates 3 of those tools. You may not be familiar with all of these. Watch and decide for yourself which tool offers the best performance in time and cost. Remember - the tool must accommodate all of the hole sizes you need for your project!

What is one of the fastest (VNE), quick to build (and affordable) KIT aircraft available today? !

We have the step by step DVDs that show how the entire aircraft is built! 
The ONEX from Sonex is a one person,  folding wing, fast (200+ vne) kit which we have documented in a series of how-to-build DVDs. It was fun and easy to build - and if this kind of aircraft spurs your interest - our DVDs will allow you to evaluate the build process as a first step in your journey to selecting the best aircraft for your needs. Researching the construction challenges for an aircraft is just as important as the demo ride!

We do not sell aircraft or take any commissions from manufacturers; we simply make how-to videos showing how they go together! We try to choose the models that will be successful for the builders - and  we have to build the kit first to prove it ourselves.
