I have a new ARF Yak that came with flat pin type hinges but i'm not too happy with the accuracy of the hinge slots. Most of the hinge slots are cut too sloppy and would need a lotr of glue just to fill the slots. I'm also not impressed with the the huge gap that they leave.

I want to use Robart Pin Hinges instead.

Is there any prefered teqnique to do this?

Should i fill the existing slots with something and then re-drill the filled glued area for the Robarts, or should i put the Robarts between the existing hinge slots.
