Hi fellow builders.
I?m concerned over my dimple metod.
I have read that there is almost impossible to "overdimple" with the c-frame tool. But also that after dimpling the rivet must not be lower than material around.
If I dimple so the rivet sits in the same height with the structure there is a gap under the rivethead. Is that normal?
On the other hand, dimpling so the rivethead sits flush makes the rivet far below the structure (overdimpling?).
I have tried whith a scrap piece different ammount of dimpling, but can never be really satisfied. Finaly I dimpled two holes in the spar.
Does those looks ok?
Also, i managed to countersink a bit to much in the reinf. angles. The pieces can be moved a bit when hold togheter, if you understand what I mean...
(Dimpled against the machined piece)
Thanks in advance.
