Could this do as an illustration to the description of your hatch hold-down construction?

I forgot one text "bubble" ,though. The black dot's between the hatch and the lip should illustrate some sort of hatch seal. I would also suggest some sort of reinforcement of the hatch around the bolt hole.

The drawing was made in corel-draw, then converted to JPG, uploaded to my home-page-aerea using a FTP-client and linked to this posting. There's also a copy in your mail-box if you want to keep it, Jay.

To save this picture, right-click inside the image, choose "save picture as" and save it in your computer.
