My position is that standard dimple dies should not be used on holes that weren't either match drilled or final drilled.
I.E., they should be made to final size before they get dimpled.

So, holes that were intended to be match drilled can't be just final drilled and then dimpled separately if there is a need for that.

So what am I to think about the quick build I received with the holes already dimpled that were to wait until the tail cone was attached?

Build on? I'm really at a loss on how I should take this and I'm not getting answers from Van's thus far.

Call the support line. Get a person on the phone. Find a solution. You're going in circles here and you're obviously not getting the answers you want or need.

Agreed. I think Scott's reply was right on which I think makes "building on" difficult.

Do you know that the holes that are already dimpled weren't final drilled first?

Nope. I'm not sure why they would have been since there would have been nothing to match drill it to. I doubt that is something that could be found out at this point.

I did have a very helpful conversation with Eric Rushing at Van's who as many know is building his own RV-10 quickbuild. What was done at the factory with those holes is clearly a mistake but Eric pointed out that the RV12's built by Synergy are dimpled without match drilling and there have been no problems with cracking. The advice was to run a Scotchbrite pad over the dimples to ensure that there are no sharp edges and build on which is really the only option at this point. Thanks Eric for the help.

By looking at the dimpled holes with a magnifying glass, perhaps you could tell if they were drilled or just punched only.

Whether they were or were not, my options are limited a this point. I'm going to follow the advice Eric at Van's gave me and trust that running the dimple die through holes that are not fully sized while not necessarily best practice won't spell doom.

Default Dimples

I would look for cracking and the polish the back side of the dimple with a 1" scotch brite in a die grinder and build on.
