A good way to put screws into the "end grain" of MDF is to use the old
fashioned fibre rawlplugs/

Drill a tight fitting hole, fill with wood glue and tap in the plugs flush
to the surface (trimming, if necessary, with a sharp chisel)

When dry, screw into the plugs - a good fixing is obtained and the chance of
splitting the MDF is much reduced.

Even using this method, 12mm is very thin for an edge fixing - have you paid
a visit to your local hardware shop to see if any of the cranked flush
hinges will allow you to fix into the back of the door where you have a
double thickness (door plus glued on paneling) to screw into?

I am aware that 12mm is very thin - my reason for using this thickness
is that 12mm main panel thickness + 6mm thickness for the false frame
= 18mm which is approximately the thickness of my edge frame (21mm or
1" nominal i.e. before planing). I guess I could go to 15mm thick MDF
but the stuff seems so heavy......

On the other hand, would 12mm + 6mm for the false framed edges joined
with plenty of glue not create a good 18mm thickness strong enough to
drill and plug in the method you described ? Or am I hoping for too
much from an MDF face-to-face glued joint ?

Thanks for your suggestion,

Gary
