[TheForge] Re: stack o' plates vs, slab o' steel

[Andrew Vida]

	I don't know about this.  Every manufacturer's foundation
	plan I have ever seen (that would be two, one for Chambersburg
	and one for Nazel) requires wood on a concrete block.  Steel
	against comparatively brittle cast iron is almost certainly a
	recipe for eventual structural failure of some form and degree.
	Don't place your hammer on a rigid surface, you will probably
	live to regret it.  Railroad ties sistered up and two to three
	courses thick should do very nicely atop a concrete foundation,
	all sunk to floor level.
