The B&B latches are real Camlocs, and are of a simpler mechanism than
those in your photos. I'll get a photo of one this evening and put it
up on the Web site tomorrow:

Here are the two photos of the oil door and $5 Camloc flush latch from
B&B:

A couple of notes and comments:

* On that oil door, I've added a 1/16" spacer to account for the
thickness of the recess into which the oil door fits. The latch is
actually designed for a door with the same thickness as the panel it
latches to.

* The spacer prevents the button from fitting flush into the push
hole, but I'll accout for that by making a new button face on the
lathe and bonding it to the original button face.

* Yet to be done is to add a U-shaped doubler of 1/8" PVC foam and
inner ply to turn the door into a stiff fiberglass sandwich.

Thanks, Bob K.
