in floor baitwell removal

[bibijawa]

I'm in the process of rebuilding the transom on my 1989 20 sf. I also want to seal the bilge access in my splashwell and cut out the floor baitwell to make it removable for bilge access. Does anyone have any pictures of the best way to cut it out and still have it stay in place when put back in?
I also want thank all you guys who post here as i have been able to find tons of information and pictures on rebuilds.
