FULL TIMER
My bad yes it's 15mm. I used the plastic knock in edgings on the framed up conversion on a few fittings, tables mainly. I cannot remember (21 years ago) how I made them up to the 15mm thickness, have to have a look manana!
The good feature of MDF is of course it's stability, not likely to get a bowing cupping the shakes and all the rest. Last time I used Vohringer a single 15mm double sided laminate 8x4 sheet €120. There was a photo finish el cheapo on poplar available at the time I think that went for 'only' €80!
The price doesn't seem to have changed much I can get it from one of our suppliers at around £100 a sheet, trouble is minimum orders and delivery costs on top of that otherwise I would use it a lot more, At the moment I'm stuck doing refurbs on St.John ambulance vehicles and guess what most of the interior kit is made of yes those bloody crappy kitchen units and 28mm worktops. I'll be glad to get back on some proper conversion work.
