Found this article...

"Single-phase induction motors drive many arbor-mounted cutting tools
in the home workshop. Stationary grinders, table and radial arm
circular saws frequently turn abrasive or cutting disks that are
directly mounted on the motor's spindle. These disks have large
inertial moments that allow them to free wheel for a long time after
the power is turned off. A lengthy coast to complete stop often
amounts to a major inconvenience."

Great ... I may rig up my table saw this way. Would be safer with a
brake. WW

If I need to stop a spinning table saw blade in a hurry to change or
reset something, I find that a scrap piece of lumber makes a great blade
brake. Turn the saw off and slide the scrap up to the still spinning
blade. Blade stops in a couple of seconds. No extra parts needed.


Someone could make some money by developing an aftermarket saw brake,
under the
table.... pads or rollers or whatever, that would squeeze the blade.

I've always wondered if a set of good quality bicycle brakes couldn't be
safely mounted on the trunnion to perform that very task. Route the cable
to the front of the saw to a hand or foot operated lever and there ya go.

The now common disk brakes might be a great match - their designed to grab a
thin metal disk instead of a wide rim.
