F-704H Dimple/C'sink

[High_Flyer]

Hi everyone,
I'm assembling the center fuselage section and I'm about to start dimpling and countersinking as required.
I've read the plans and the instructions but I don't see anywhere if I have to dimple or countersink F-704H side plates. These are the plates going between the F-704 bulkhead and the side skins.
I believe that these 2 plates have to be countersunk (only for flush rivets) because of the thickness of the metal, however I still have a doubt.






Thanks...
Alain.

Countersink

I'm building a -8 but we have the same thing going on at this location. The skin dimples, the reinforcement plate countersinks and the bulkhead gets nothing.

That's what I thought

Thanks Robert,
That's what I thought and is what I'm going to do.
Happy riveting on your -8.

Alain, I'm about a week behind you (I hope!).

For 3/32 rivets, I dimple 0.040 and thinner, and countersinnk anything thicker, unless otherwise called out in the plans (aft edges of fuel tank skins come to mind).
