RV7 Newbie question

I have just started the Horizontal Stabilizer. I have a question regarding trimming of the HS-702 Forward Spar flanges. If I trim the flanges from the relief notch inboard the remaining web will be narrower because of the flange radius. Do most builders unbend the flange inboard of the notch, unbend the flange then trim what remains of the flange off or just taper the flange in from the transition.

Assistance is appreciated.

Scottie,

No need to unbend the flange and make it even with the edges of the spar. Narrower is what most people do.

It is what I did. If you do the same, we could just fall out of the sky together!

Good luck and have fun building!

Hi ScottT,

Here is how I did it, making sure there was still at least 1/4" edge distance to the rivet holes. I thought about bending the edge too, but just smoothed it out.

When you go to drill the rivet holes in the flanges using the center line they tell you to draw, make sure it stays centered in the skin holes as you drill. In other words, make sure those spars stay well clamped or they might shift too much and cause you to have to buy a new one
