I also finished filing, edge deburring, and other related prep tasks for the RV-10 ailerons. Now I can start the assembly process. I'm excited to get the wings completed so I can get to work on the fuselage. I am debating whether or not I should do the wing tips now or later. I am leaning toward doing it now so I can take the wings to the airport for storage.
|First step was to design the duct using Solidworks.
|Here is the 3D printed ducting. I also added a 3/4" aluminum ring to the inside of the duct to act as a stiffener where the hose clamp will hold the flexible hose to the duct.
|Here is the finished product after a little sanding and adding a final thin coat of epoxy. Not bad.
|Here is a side view of the duct after bolting to the oil cooler.
|Front view so I can verify it won't interfere with the cowling.
|Inside view of the duct after bolting to oil cooler. You can see a little bead of red RTV on the bottom edge of the duct. This keeps all of the air going through the cooler.
