That's a good point, I suppose with say two layers of 3/4" MDF screwed heavily to a 2X6 might just keep it inline... again, I have little experience with MDF, this will be my first MDF project... but otherwise "2-by" lumber
can potentially warp very severely, can be hard to hold it inline.
In my case I wish to make the doors no thicker than 1.75" total. If I use a 2X6 frame (1.5"), I have only a quarter inch left to add paneling on top. Unless I route the edges of the 2X6s and try to add the MDF within the frame, but this starts to get laborious.
My limitation on thickness is surely making things tough for me, but I'll give it a shot. If dual 3/4" MDF with a 1/4" decorative panel on top (1.75" total) actually works, this will prove to be a fairly simple cost effective way of making a door with over 6 PSF mass (which in most cases is more than enough for a two door situation) but yet not be thicker than a standard fire-core door so that standard hardware will fit and standard sized jambs etc can be used, etc.
Who knows, my experiment here may not work out well at all... might turn out to be a big waste of time and MDF... I'll let y'all know either way. To me it's worth a shot to have 6 PSF doors that are just 1.75" thick for under $75 or whatever.
Side note... I built my custom door jambs 38" wide so that IF my custom efforts totally fail, I can always throw in some type of standard 36" door with jamb (38" is the typical rough opening for standard 36" doors)... trying to keep all options open. But I hope to build some effective custom 38" wide doors though... will try.
