VS lightening holes
Since I was tired of deburring holes and the new fly cutter arrived, I decided to try making the optional lightening holes in the VS rear spar stiffener. Got it all measured out and ready to drill. Luckily, I noticed at the last minute that I had dialed in the circumference measurement on the fly cutter instead of the radius. I almost made a 3″ hole instead of 1.5″. Here’s the fly cutter in action.
Unfortunately, the fly cutter only goes down to 1.75″ holes. I just used a unibit to make 3/4″ holes instead of the 1.5″ holes. Smaller certainly won’t hurt. Here’s the finished product. Not sure the few ounces I saved was worth all of the hassle, but it was a learning experience.
