Here is a picture of a hi fi cabinet that I made for a friend. Is made of both solid ash and ash veneered MDF. It ended up being a VERY heavy bit of furniture indeed. I didn't like using the MDF but it seems that in this country veneered ply is not easy to come by. It will need to be supported in the centre but for now is supported by a bit of scrap.
