Cases came from Farrier Marine. When you see them you will realise they are really very good value.
Frames are made from MDF sealed with clear lacquer on the faces and 2 coats of epoxy along the edges.
Where are you located? I'm on the NSW Central Coast .
If you are not too far away you can send me a PM with your number we can talk about frames and any general questions that you may have re building etc.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
