I'll post some pictures later tonight of my finished hood.
Costs are approximate:
$32 - FRP
$ 5 - Lath screws
$12 - 2x4's
$14 - Plywood half-sheet
$12 - Vinyl J-Channel
---
$76
Cut two plywood end caps that are half-circles with a 15.25" radius. This dimension allows the 4' end of the FRP sheet to be fully utilized.
Cut your FRP pieces to match your end caps. I screwed rectangular pieces of FRP to the plywood end caps then routered around the edges to get the FRP lined up with the plywood as closely as possible. Probably best to cut your duct hole in one end cap before attaching FRP, then jigsaw or router out FRP in hole.
Your larger piece of FRP should be 66.5" (96" - 30.5") long by 48" wide. With someone assisting start at bottom of your half-circle plywood end cap and screw the 48" side of the FRP into it every 6 inches or so.
Once that is done, drop your 2x4 rectangular frame onto the hood. At this point you can work in your J-Channel between the FRP and 2x4's to catch condensation.
I've not determined yet how I'm going to seal the J-Channel mitered joints, so any suggestions would be great.
