Bracing material?
 
MDF does not seem too resistant to bending and I wonder if it is ideally suited to be used as cabinet bracing? Would it be better, worse or irrelevant to use something stiffer like plywood or hardwood dowels for the bracing structures?

I would look for an alternate to mdf for bracing. Even pine 1x's would perform better.

MDF does not make good braces.It doesn't make all that great a speaker box either.

Quality ply or hardwoods make good braces.

MDF makes good kindling. Dry, incendiary adhesives, did I mention dry? Otherwise, use something structural. Engineers don't call for MDF anything.

I always make my cabinets from 18mm plywood with 2inch square bracing.

I once made a cabinet from chipboard and it got wet once and fell apart !

Burning MDF smells awful! :D

And that smell is from noxious chemicals. I always burn it in a HOT fire outside (in the rain if i can get the timing right).

It depends on how you plan on bracing. Are you talking triangular corner blocks, 'shelf' type with holes, or simple straps across the box? I suspect mdf would be fine for the first, adequate for the second, and inappropriate for the third.

I may use a combo of all configurations...thanks.
