I am currently converting an antique radio into a computer case. Circa
1930s. The back is open and originally has a cardboard-like material. I am having trouble figuring out how to fit a MDF panel to sit flush with the back (effectivly inset in the radio's back.) but it isn't an easy shape to fit. To make it more difficult it must be air-tight (i'll have to put some kind of weather stripping around the edges.in short the back panel needs to open up like a door, but when closed is inset inside the radio's original housing.
My first tought was to try and build a board with a nail at 1 end pointing down with a pen at the opposite end then trace the interior boundaries and hope that I can keep the board straight as not to skew the pattern.
Any ideas on a simpler option? I am working with 1/2 inch MDF for the panel. I have the identical problem (sans the door part) for creating a bottom.
