Proper priming, dimpling, countersinking and finally some back-riveting

Started with dimpling the rudder skins. Went well and did not take that much time, it was well worth the time to fix a good surface with the correct height for the skins to rest at. I plan to make some permanent tabletops to make this an easy task for the future. This might be something to work on while being forced to wait which takes me to the next step, priming that ends with waiting for parts to dry up.

The priming went fantastic and the cleaning up after was much easier than expected! Decided to better the priming on some of the smaller parts.

Next step was some more dimpling, the holes that could not be done with the C-frame. After a break thinking, I then grinded a piece of wood with a slight angle to be able to machine countersink as instructed. The actual work took less time than the preparation. Result looks great.

Ended up with attaching two ribs to a skin, I do not have a back riveting device, used the ordinary dies. An OK result but I want better tools, I plan to drill out at least four of today's around 20 rivets.
