Glue and screw MDF together. If you drill proper pilot holes, screws hold
great. Not that they real have to hold anything. Glue a couple pieces of MDF
together with Titebond sometime then take a hammer to it. You will pulverize
the MDF before that glue joint fails.

and do NOT forget to drill the pilot holes. MDF doesn't like
screws driven into it point blank. DAMHIKT...
