* Consider if you want to provide insulation and/or additional fire protection on the hot side of the firewall. Some people use Lava Shield and Dan Horton offers a FiberFrax kit. You can't install anything like this until all of the riveting is done much later, but you may want to trim and otherwise prepare before the firewall is installed since it will be much easier to do it when flat on a table. | |||

One of the nutplates mounted to F-1001B is mounted on the forward side of the firewall, which means you don't need to countersink the mounting holes into F-1001B for that one nutplate (as shown on page 27-5). | One of the nutplates mounted to F-1001B is mounted on the forward side of the firewall, which means you don't need to countersink the mounting holes into F-1001B for that one nutplate (as shown on page 27-5). | ||
Note that every #30 and #40 hole on the firewall needs to be dimpled flush on the forward side except the two forward-mounted nutplates as already mentioned. Do NOT dimple any of the larger holes. The flanges also need to be dimpled to accept the forward fuselage skins. | |||

Step 2: I don't know how you are supposed to rivet F-1039D to the firewall recess. My rivet gun won't fit into the recess. I used a double-offset back rivet head (not included in the standard tool kits for RV-10) on the inside of the firewall but it wasn't the cleanest rivet job. | Step 2: I don't know how you are supposed to rivet F-1039D to the firewall recess.

If you will be using the stock oil cooler, now is the easiest time to rivet the mounting box onto the firewall. Consider doing all six steps from FF1-2 at this time. | |||
Note: most people replace the aluminum TG-10-R and TG-10-L cabin heat selector boxes with stainless steel versions. You also might want to insulate the cabin from these valves so that heat doesn't transfer even when the valves are closed.

If you are going to install any sort additional heat/fire protection on the hot side of the firewall, you probably want to hold off on installing the VENT TG-10-L and TG-10-R (or their stainless steel version) until after you have finished that process. Although now would be a great time to prep/trim any such additional insulation, you can't install it until much later when all of the rivets are complete. | |||
