A nice post over at Popular Woodworking shows how easy it is to replace an insert on a Byrd Cutterhead. If you can afford one, that is.
The most nervewracking part of building a shelf are drilling all of those holes for the shelf-pins, and you’ve got two options: fixed shelves, or finding a good jig. Greg Portland has a good review of the options on the market right now over at Sawmill Creek.
Alot of great discussion in the comments over at the Wood Whisperer about a possible move to require Saw-Stop like technology in tablesaws. He also points out a new competitor called Whirlwind that takes a different approach, using proximity sensors rather than conductivity. Seems like a great idea, and I can’t wait to see if this gets picked up by some of the manufacturers.
