I put some thought into this topic over the weekend after reading quite a few issues of Woodworking magazine (Chris Schwartz's mag), and it occurs to me that perhaps Chris was referring more to furniture in his style preferences (shaker and arts & crafts) when he stated that "counterfiet furniture is big business", rather than the hand-made products of the colonial or federal period.
If that's true, than perhaps his statement makes more sense. Since most Arts & Crafts furjiture was produced using machines to specific dimensions, it would be considerably easier to fake a Stickley table than it would be to fake a high-style handmade piece from the 18th century, where not only oxidation and wear would have to be duplicated, but the marks of hand tools as well as construction idiosyncracies specific to a particular master's shop.
