Horizontal Stabilizer -3

After assembling and match drilling everything the steps called for dimpling the ribs and skins. I decided to use the main squezer to dimple the ribs in the same way we did back in December when we attendend the Synergy Air class. It was actually pretty straight foward and the results were as expected.

Once I started to dimple the skins, I was getting less than ideal results. After reading the DRDT-2 manual a couple more times, and running some searches on VAF, I came to the conclusion that I had the wrong setup. My holes were under dimpled, adding a little bit of pre-load fixed the issue. After re-dimpling the holes the results were pretty good and consistent.

Machine countersinking the spars and doublers was pretty easy. Just a matter of seting the stops to the right depth, and slowly making my way through every hole. I’ll probably need to add an extra battery for my drill or get anoter one.
