Dimpled elevator stiffeners

I'm on call @ work this weekend, so not enough time to do any meaningful RV-7 work... but progress is progress, right?

Here are a couple of shots of the dimpled stiffeners. The DRDT-2 made quick work of these.

More later. Hope everyone has a great weekend.  :)

Elevator skins/stiffeners match-drilled, deburred, primed, etc.

Hey everyone, it's been a while! Been putting in consistant 60-hr weeks @ work, and traveling- which left precious little time for anything else. All I've managed to get done is to match-drill the stiffeners to the elevator skins.

Like before with the rudder, the elevator stiffeners are fabricated from prepunched lengths of alclad stock.

Cut to length and shaped accordingly, they are then edge-finished, radiused, and match drilled to the skins. The metal shears are used in combination with the Scotch-Brite wheel, as usual.

Here is how they look when all the cutting and shaping is finished- nice and smooth.

Here you can see the scrap that has been trimmed from the raw stock.

Again, as with the rudder, the completed stiffeners are clecoed to the elevator skins and match-drilled. You have to pay careful attention to the plans, as some of the stiffeners get trimmed again to match their respective control surface, and then you have to mark ALL of the stiffeners so you can remember their individual locations- otherwise your holes will never match up again!  :)

Here's a skin with the stiffeners clecoed to it.

And here are all the stiffeners- deburred, match-drilled and primed.

Next steps will be to dimple all stiffeners & skins, and back-rivet them into place. At the rate things are going, you might want to check back in October! Take care, all  ;)
