My rule, always dimple, unless it is impossible.

I agree, but the question here is perhaps a bit different:
You can't dimple the longeron so:
Dimpling the lower of two overlapping skins will require machine
countersinking the longeron to accept the intermediate skin dimple.
Would it be better to lose the metal from a machine coutersink in the
intermediate skin and only a hairs width from the longeron?
In either case, I WILL always be dimpling the top (outer) skin.
So:, I plan to machine countersink the longerons only for the keeper
rivets in the rear, and along the canopy areas where there is no
overlapping top skin.
Is this right?
Thanks,
Jim

RV7:
Reading online threads it looks like the advice is to:
(Areas where top & bottom skins overlap at longeron): Machine
countersink through the lower skin and into the longeron to accept a
dimple made in the top skin
Question:
(Areas where lower skin has no overlapping top skin):
Should I dimple the lower skin and full countersink the longeron to
accept the dimple?
OR:
Should I machine countersink the lower skin and longeron (1 step).
(Leaves undesireable thin sidewall bearing area on skin)
Thanks,
