Actually most of his ideas are in the public domain. Correct me if I'm wrong but I think that only his front weight methodologies are protected by patent. Everything else is available in his articles, though it does take a few readings to digest the ideas and a lot more work to develop your own methods. I don't really blame David for trying to parlay his ideas into making money. I don't know about you but I don't enjoy pounding away on spinets and funky old uprights, so I salute those folks who have created a way to make a living in this field while avoiding at least some of the drudgery. The problem for David is that he is more of an idea person than an engineer. To contrast, take Bill Spurlock. Bill has written copious methodological articles for the PTG and given many presentations explaining ways to do things. And he has created lots of tools to make the job easier. He sells us the tools and everyone is happy. (I'd love to see all the Rube Goldberg devices that are now sitting unused on peoples shelves after Bill came up with a better mousetrap!) Actually, if so inclined, anyone can use his methods and build their own tools that mimic his and he doesn't get a dime from it. So all of Bill's stuff is really in the public domain, but his execution in tool building is so good that people buy his tools even though they could make them. Bill is able to make a living by selling tools and giving away his methods. David, on the other hand, has given away a good portion of his concepts, but has decided to sell some of his methods instead of tools. It's a much harder sell - intellectual property. Personally, I would have preferred for David to have gone Spurlock's route and explained his methods in detail and then developed and sold the tools that Bob Marinelli is selling. It is interesting to me though that David has kept especially the front weight methods protected by patent. My feeling is that the front weight is of overall less importance than strike weight because SW accounts for more (75%, if I've understood B Spurlock and Darrell Fandrich) of the inertia in the system. So if you 1) take good care of friction throughout the action, and as Ric and Jon point out, 2) take pains to achieve uniform SW, and 3) match the SW to the action ratio, front weight won't be difficult to deal with. (Yeah, I know, I know.... it's circular - that in order to know the ratio, you gotta know FW...., so you use a reasonable "guess" of FW for calculations.) One thing about David's FW ideas that is certain though is that if you insist on adhering to the FW ceiling, then many actions will require wip assist springs (turbo wips). Maybe that's a good thing. Maybe not. I'm just not convinced that a "reasonable" amount of lead in the key is as big an issue as SW and other geomety issues. In the end though, I really appreciate the enormous contribution that David has made to my understanding of actions. FWIW, Alan (Caution: Mind under Construction.
