I went ahead and formed a few more so I could make

the top hatch and view port, still need another for

the lower hatch.

Here is the hatch sanded down to the correct

diameter.

I just sat it up there and traced a line around the hatch,

so I would have a reference of where to cut away.

I marked two circles one outer and one inner, the outer was left

to be flat sanded the inner I dremeled out.

The flat sanding gives you the lip for the hatch to sit on.

Here is the lip I mentioned.

Top hatch test fitting.

Reference circle for the front view port.....done the same way

as the top hatch.
