In order to dimple the rearmost holes on R-903 and R-904 (top and bottom ribs respectively), I broke out a tool I made while building the practice control surface from Van’s. \u00a0It’s basically just a small piece of steel that’s been drilled and countersunk for #30 and #40 drills.<\/p>\n

<\/a><\/center>
\nHere you can see how it’s used. \u00a0The rib is slipped over it and the rivet gun is set up with a special rivet set that holds any type of squeezer set. \u00a0Here it’s holding the #40 male dimple set. \u00a0A few hits with the rivet gun and this creates a nice dimple.<\/p>\n

<\/a><\/center>
\nNext up was to countersink the trailing edge wedge. \u00a0Unlike the other control surfaces on the RV-7 which use a folded trailing edge, the rudder uses two separate skins that are joined at the trailing edge with this wedge. \u00a0This is countersunk from both sides to receive the dimples from the skins. \u00a0A rivet is then set against a back rivet set such that it fills the dimples on both sides of the rudder.<\/p>\n

<\/a><\/center>
\nOne skin fully deburred on both sides. \u00a0The RV-7 rudder uses very thin 0.016″ skins, so you have to be very careful when deburring to avoid removing so much material that the inside of the hole has a knife edge.<\/p>\n

<\/a><\/center>
\nHere’s the same skin fully dimpled. \u00a0I only need to prep the other skin, prep and prime the internal components, and the rudder will be ready to assemble.<\/p>\n
