I'm building a euro-style frameless bathroom vanity with figured anigre veneer for the cabinet doors and drawer fronts. I'll be using Blum concealed euro hinges on the doors. What is the best substrate to use for the doors? I'm trying to balance panel stability vs. fastener-holding ability. For stability I'd go with MR MDF, but I'm concerned that the MDF has poor fastener holding ability. Would lumber-core be a better option, or is the MDF strong enough?
From contributor J:
I use the ultra-lite MDF for doors because it is lightweight and less stress on the Blum hinges. I use the Blum with the dowel insert. They're threaded and have never had any problems. The panels stay very flat also.
I have had lumbercore ply warp on me, so I won't use it anymore for slab doors. Others may have different opinions on this.
