Elevator trim tab and spar tips

Ducked over to the shop tonight to work on making some 0.025 aluminum parts.

My original intention was to to start making the numerous (64? Are you kidding me!) 4 foot standard "L"s needed for my build, but I decided I wanted to accomplish something more tangible.

I cut out the 0.025 skin for the elevator trim tab.  I'm going to leave it flat for now until I have more time to concentrate on bending it.  It's a fairly complex bend over a narrow piece of aluminum, so it will pay to think it out well before committing to the bender.

Next I started and completed the wing spar tips.  By laying them out opposite to each other on the aluminum sheet, I saved a some cutting and and prevented waste.

Once I had them cut out the next challenge was to bend opposite flanges with the correct web space between.  Thankfully I had done this before on the 701 wing extension, so it was fairly simple.

Two perfectly matched wing spar tips, one left one right. I guess I could have taken a picture before bending them to show how one angled tip is the exact oppostite of the other

After making the correct bends (I had to think about which side was which) I laid out the measurements for the lightening holes.  Once satisfied, it was back to the fly-cutter.

All secure on the drill press, ready to "fly"

As dangerous a tool as the fly-cutter can be, it does a quick job of making a clean dimensional hole in sheet aluminum. The last time I used this tool, I cut the hole a tad small, making the flange die difficult to use, so this time I widened the hole slightly

Depsite my efforts to size the hole correctly, I had a bit of a rough time flanging the holes evenly.  They will need a bit more work from the flanging die.  Other than that they turned out real nice.

That's it for tonight, thanks for following along!
