Amazing Table saw safety

IMHO, the saw will not be a viable product until the cartrige is available from a second or third source. (i.e. Similar in concept to generic drugs.) I considered the saw when I purchased my new saw. The cartrige second source was a major issue for me and a left tilt only was the feature that squashed the deal.

There is a whole frame work that holds the arbor and it's bearings. Taking a blade thats spinning at around 3000rpm and stopping it in less than a 1/4 turn will exert an increadible amount of force on that frame and the other parts that hold that frame... You can can't deny that there's going to be some serious amount of flex taking place in the whole mechanism and I doubt things will go back together perfectly afterwards. Most people would be greatful, me included, if the saw self distructed but saved a body part but it would be wishful thinking to expect the saw to ever cut true ever again.

I've seen this thing before

I honestly think it is an ill concieved device.

It addresses only a small part of the safety concerns of the table saw and functioning of the safety device results in permanent damage to the tool in use requiring repair.

Consider the cost of tripping the safety device regardless of cause.

If you use nice saw blades and the cost of the brake cartridge it would not be unreasonable to sa $200 each time plus the down time.
There is no way it will take less than 1/2 an hour probaly more like an hour to replace the various parts.

No sorry bad idea.:no:

cheers

Good idea for untrained idjits who shouldn't be using such a tool anyway. For the rest of us, training and enlightened precautions are hard to beat. And in a workplace situation, enforcement of safety rules. About 35 years ago, we had an old phard cabinetmaker who absolutely refused to use a push stick; sure enough, one day he merrily shoved his thumb through the blade. Should have been sacked before then.
