Default Robart instead of CA

Want to use Robart hinges instead of the already slotted CA's. Do I just drill for the Robarts where the CA's are already slotted? Will the CA slot crack from the Robarts as the epoxy cures?

Any thoughts appreciated.

No problem. Throwing a little carpenters glue in the slots before installing the hinges wouldn't hurt, but I don't think it's a MUST DO kind of thing either.

Another alternative is the nylon pinned hinges by Klett or Du-bro. Just need to widen the groove a bit. I use Goop to hold them in. Robarts work well too depending on the application.

Another option--the Hayes (used to be Kraft-Hayes) hinges. Like the Robart, but without the round post portion. Just enlarge the CA slots slightly, and put them in with slow-dry epoxy. Last longer than the airplane in most cases, and you don't have to worry about lining up the drilled holes for the Robart.

I just had to replace the C/A hinges on my Extra because the hinge broke at the center line. I have never heard of this happening before.
