I've hit wood clamps once or twice but just a glancing blow so no broken bit. I hit a screw once and that was enough to suitably dull the bit but it didn't break.
hmmm..... Interesting idea.I've seen but not tried using a biscuit jointer or domino machine to cut slots in the side of boards for clamps to hook into when you can't put a clamp over the top of the piece.
Another idea worth trying, thank you. I've had the issue of a work piece lifting a little when using my home made cam clamps; I could never get a tight enough pinch. The wedge sounds like it may "bind" better.I've also used wedges to clamp parts against a fixed edge. Bolt or clamp one tapered edge half down a short distance from the material being held, then slide a loose tapered board between the fixed half and the material board. Tap in place to lock the material in place. Tap on the other end to free the wedge. The long face of the wedge against the board holds better than the tangent edge of a cam rotating clamp.
I haven't had a bit go flying yet they mainly just drop on the table top. i have had pieces of projects go flying and embed themselves in my 3/4" foam enclosure box I have over the top of the CNC like a big foam cooler that sits over the top of the 40x 50" table.newbie question: is this dangerous? my router's bit is not protected behind any kind of shield, so if it breaks wouldn't it go flying (towards me...)?
