: Hi Dave, when I finished my Night Heron stripper and was ready for
: varnish I cut the hatches out put them aside to build the hatch
: platform then was called away from the project for a week, on
: returning to building project I found the hatches relaxed a
: slight bit
: enough for me to see. So I would consider making a jig that
: conforms to the deck and clamp it until you finish bracing the
: underside
: of the deck hatch. Nick R.

Alternatively you can either lay extra glass under the hatch before you cut it out or glue wood braces under the hatch before cutting it. Either way you don't need to bother with a jig or worry about the hatch flattening itself.
