I started on the firewall-forward installation. I'm still waiting on some parts, so I'm also picking items off while I wait. This week I did the following:
-Swaged rudder cables.
-Made and installed the tail access covers.
-Installed some aluminum angle and strips for the cargo bag velcro.
-Installed COM/XPDR/ADSB antennae
-Hung the engine.
-Installed the coolant overflow bottle, fuel filter, and fuel shutoff valve.
-Started installing the cabin heater. My drill stop collar slipped while drilling rivet holes and I nicked the heater core. That's some thin aluminum! I'm going to try an epoxy repair before I drop $170 on a new heater core.
-Installed the brake system except the parking brake (arrives tomorrow).
-Fabricated and installed quarter windows.

For the cargo bag velcro, I put two angles in with Adel clamps. I also bonded some Al strips to the bottom tube of the quarter window that aren't shown in the picture.


On the brakes, if you heat the nylaflow tube in some hot water or with a heat gun, you can form it, and then run it under cold water so that it takes a set. This way you can make reasonably sharp bends without kinking the tube. This is handy where the brake lines go through the fabric to gear legs.
