Worked on it some more sunday morning. I decided to reposition the monting ring a bit, so tonight I might do that then stretch cloth around the front.
Finished glassing the mold
Ring mounted:
plenty of clearance
Test fit in hatch. The top edge just clears, so I think I may move it a bit
And the mold trimmed up. I just need to round the corners over a bit to make it look nicer
