Looking at yesterdays work...I think I need to add more rivets. The spacing is just too far apart.
Adding extra rivets is not a big deal with the use of the fan spacer. Its looking much better now. Now I need to clean up all the corners and debur the holes, most important is to ensure a good fit of the bulkhead grommets. The fit is excellent so I need to dimple everything before priming. The stainless steel firewall is easy to dimple with the pop rivet dimpler. Just takes a lot of finishing nails as there are so many rivet holes now.
