Throttle panel, induction air flange, oil door hartwell latch, door strake extensions

The throttle panel flange had cured, so got to work on cleaning that up. Also cut the oil access door for the Hartwell style flush latch.

Here's the throttle panel as laid up. Somehow I don't have a picture of it after I trimmed it.

Once that was trimmed, I measured and drilled pilot holes for the engine controls to use to hold to the layup/mounting point that exists in the fuselage. I then drilled holes through the panel and flange that will get drilled out later for nutplates, but for now serve as holding points for the clecos to temporarily hold it together.

The three clelos on the engine control panel are where the holes for the throttle, prop (if I had one), and mixture will go.

Installed

Once that was ready, I made up some structural adhesive with cabo and adhered it to the existing mounting point. If the mount point had not already existed, I would have just done a layup here from the fuselage onto the panel.

(Editor's note: I originally intended to later do a layup of 4 bid or something from the fuselage onto the existing mount point and then onto the engine control panel, but this is incredibly strong as-is, so I'm just going to leave it.)

Smooshed into place on the existing flange.

While I had a batch of adhesive, I also glued the hartwell latch onto the oil door and tubing flange onto the fuel servo induction air flange that I fabricated. Both were also secured with rivets.
