It's not simply three lumps of MDF, it's quite complex. In any case, the existing cabinet is original and apart from applying new veneer I want to keep it that way.

But veneering it is not going to be easy. Firstly, the middle section has to slot into a channel in the chassis front panel, so veneering on top of what is already there will make it too thick. I may have to reduce the thickness of the top panel by removing a layer of veneer from the plywood - not easy given its 'in situ' status. Similarly, I cannot veneer the inside faces of the side panels as that will make the inside measurement of the whole assembly smaller, so it would then not slip over the receiver chassis. I will 'colour' those inside panels to match the lacquered new veneer; you see next to nothing of the inside faces of the side panels anyway.

I'm working it all out in my head, and I'll get there I'm sure.
