The video “Have they BANNED table saw dado sets????” is by Stumpy Nubs (James Hamilton). In this engaging discussion, James dives deep into the controversial topic of dado sets, particularly the differing views on their usage across the globe. Are they really banned in some places? Why?
Dado Sets: A Closer Look
James begins by addressing the comfort level of American woodworkers with dado sets. In the United States, it’s common practice to stack multiple table saw blades to create wide kerfs for various joinery techniques, including dados, grooves, rabbits, and tenons. It’s worth noting that James refers to a “rabbit” and not a “rebate,” showcasing the quirky terminology differences that exist in woodworking.
However, he contrasts this with the perspective of international woodworkers, particularly in Europe, where dado sets are viewed with caution. In some countries, the government has taken legislative steps to protect citizens from what they perceive as dangerous tools, likening dado sets to the infamous wood chipper from the movie Fargo. In other nations, while you can own a dado set, restrictions on table saws with long enough arbors to accommodate them exist.
James explains that many of his international viewers have little to no experience with dado sets. When they see one in a video, they often brace themselves for potential disaster, expecting it to cause severe injuries. He humorously reflects on the notion that perhaps Europeans know something about dado sets that Americans don’t.
The Real Issues Behind Dado Set Restrictions
James delves into the two main reasons behind the restrictions on dado sets in Europe: braking systems and blade guards. In many European countries, particularly those used for commercial activities, table saws must have electronic braking systems that stop the blade within ten seconds of turning off. This rapid stopping can be problematic with heavy dado stacks, as the momentum could loosen the arbor nut, potentially causing the blade to detach.
Moreover, using a dado set requires the removal of the blade guard and splitter or riving knife, which are critical for preventing kickback. He acknowledges that while kickback is rare when making non-through cuts with dado sets, the lack of a riving knife creates a safety concern that justifies the restrictions.
A Unique Solution
After laying out the problems, James presents his solution to the great dado set debate: floating blade guards. These guards cover the saw blade, addressing two of the three concerns authorities have with dado sets. With a floating blade guard in place, the time it takes for the blade to coast to a stop becomes irrelevant, eliminating the need for electronic brakes. Additionally, it keeps the blade covered during non-through cuts.
However, he admits that his solution doesn’t fully address the incompatibility of riving knives with dado sets. Despite this, James believes that the risk of kickback is exceedingly rare when making non-through cuts with dado sets, making his floating blade guard a promising alternative to current regulations.
Final Thoughts
In conclusion, James brings a friendly and knowledgeable voice to the often contentious topic of dado sets. His insights into the differing regulations and safety concerns across countries provide valuable context for woodworkers everywhere. With a touch of humor and a passion for woodworking, he continues to foster a love for the craft while addressing the complexities that come with it.
