Finished countersinking the counterbalance weight (pipe) on the left aileron and proceeded to dimple everything. Had a rough time dimpling the spar as it is right against the max size to dimple, but the plans didn't call for countersinking so I pressed on. Everything else when well and I hope to finish dimpling and prime in the next session or two.
Dimpling the spar with the DRDT-2. I eventually moved to the hand squeezer for this.
Dimpling for the blind rivet holes on the leading edge for the counterweight (pipe)
