The following is an article regarding Saw Stop's continuing agenda to force manufacturers to use their mechanism to prevent injuries. http://www.designnews.com/CA6360672.html
If you read the article you will see that engineers from the U.S. Consumer Product Safety Commission recommended that the government begin a “rulemaking process” that could result in mandatory safety standards for table saws. The agency’s commissioners have concurred with the recommendation.
Please do not take my posting of this to be anti-SawStop, but I am always skeptical when the guy who makes the product is the voice touting its need and requesting that the government mandate its use. I for one am certain that if regulations are adopted, the SawStop will not be the technology that wins this battle. I think they burned a bridge or two with their method of affecting the change that they wanted, that and an exorbitant 8% royalty fee is enough to make the big boys develop their own technology. Perhaps the creator of this technology really only wants to see safety improved, but my guess is that he wants to see it mainly because it impacts his bottom line positively (which I have no problem with).
I for one am hoping that it isn't successful because I simply prefer less regulation.
