Anyone buy Hal's set of plans for five different sizes of his rocker? The samples of pages of the plans don't really give much of a feel for the level of detail in the plans. If they include methods for making the joints along with full size patterns for $55/chair plans seems like a good deal. Could save a lot of trial and error and be a very valuable source of specialized techniques.
As for the similarity to Sam Maloof rockers, the former's rockers are "s" shaped, Hal's aren't. Hal's front legs/ armrest supports are inward "c's", Maloof's are straighter. Maloof's seats are very low, Hal's are at a more traditional height.
I'm sure Hal utilizes some of the joinery Sam Maloof used. If you study oriental furniture joinery you'll see that Maloof didn't invent the joining methods he uses.
Bottom line, we all build on the knowledge developed by others. Occassionaly we think we "create" something new but a little researching usually shows it's been done many times before. There is very little new under the sun.
