Engine Cowling - Oil Dipstick Door

With this cowling not being easily removeable an access door must be provided to get to the Oil Dipstick to check the oil level.  I cut the above opening in the top of the cowling to provide access directly below.
I found a hinge on an access panel from a wreak at the local Air Salvage operation.  I removed the original panel and attached the hinge to the panel I had cut out and to the cowling.

A glass layer was bonded to the inside of the cowling.
This will make the lip aroung the opening.

The latches were added to the panel and the center section cut out to provide the needed inside lip.
I blew it with installing the latches before I fit the lip and put them too close to the edge.  Should have been back 1/2 in.

The door has been trimmed to round the corners.
Tape was applied to the edges and the gaps filled.

After multiple filling and sanding operations the door was primed along with the cowling.  Looks OK?

Perfect?  No exactly.  Whe latched it pulls down more than I had wanted and slightly distorts the panel.  The photo actually makes it look worse than it is.

While it's not perfect it works as intended and I like it.  Double latch was not necessary but I it's not going to come open in flight and it ties the corners down tight.
