This piece of work took WAY longer than I had expected. And it didn’t turn out quite as nice as I would have liked either. But I don’t think you can get it any better, it is just the latches and fiberglass oil door don’t work super well together. Plus the sanding involved getting these latches to fit was messy and time consuming.
But the latches fit quite flush and do look pretty good overall. We’ll see if I can get them to look any nicer with some additional work. You need two latches on the oil door because of the pressure inside the cowling. It will pop open other less significant latches as the door flexes.. Plus I will put a layer or two of fiberglass on the inside of the door to help stiffen it up.
