Oops! I just saw this! I had shared this link somewhere else on Cubits, so I had better share it here: http://www.wimp.com/amazingtechnology/
If you own a tablesaw, you must own this!
My brother has one of these on his table saw as does his brother in law. The brother in law has had to replace his twice, but he still has all of his fingers.
I have a table saw too, something that I would find difficult to do without as indeed I would my fingers! All power tools are potentially dangerous regardless of which they are, always study the instructions and follow them to the letter would be my advice here. Golden rules keep your fingers at least 6" away from a rotating blade, don't wear loose clothing and tie back long hair! Disconnect from the power supply as soon as you have finished using the tool, never use any tool you are not confident with or doubt it's safety.
You Two!
