Dimple Die Set for #10 Screw?

[RV7AJeremy]

I am working on the rudder and I need to countersink the counter weight and dimple the rib to a #10 dimple. I do not have a #10 dimple so my question is: will I need to use the #10 dimple die at other points in the build/is it worth buying a #10 dimple die or is this the only place I will need it?

Thanks for your military service.

I am nearly complete with my 7 and remember only a few places where the #10 dimple is used.
I fabricated a die from a small pc of 1/4" thick aluminum by drilling a 13/64" hole and countersinking so the #10 screw head fit flush.
I used the screw along with a nut to form the dimple.

Ditto, I think this procedure is fairly common... not a great need for those dies in our kits.
