Hello woodworkers,
I just bought a Makita circular saw (5007FAK). It was the cheapest saw
I found at home Depot with an electric brake.
In my newbie mind, I expected the blade to stop very fast (sub 1
second, a couple or revolutions, or something like that). It actually
takes over 2 seconds.
What should be the typical time necessary for the blade to stop. With
brake, and without? There was also a DeWalt saw with brake at the
store, but it was about 70$ cdn more.
Thanks for any answer
JC

That's plenty fast enough...the whole idea of the blade brake is just to
make the saw safer to handle after the cut.....2 seconds as opposed to a
blade gradually winding down lets you get on with your work faster, not
having to worry about a still spinning blade catching your cord or worst
still your fingers if careless....I find the electric brake a great
indicator of the brushes or switch needing replacing as well...when the
brake becomes intermittent or not working at all check first the brushes, if
they are still good size & shape then suspect the switch.

That's fast enough. I've never used one with a brake, I don't think you really
need one if you're safe. They're a recent thing in the last few years on
smaller saws. My Skil HD77 has enough oomph to take off your hand, after the
power's turned off.

LOL... the bearings must be going bad in that one..;~)
A piece of 2x4 is pushed into the side of the blade on the one where I buy
wood. I takes about 5 seconds to stop with that method.
You need to stop at an old lumber yard some day to watch and
listen to that big old DeWalt radial arm saw. Once you push the
off button you could come back tomorrow morning to finally see it
coast to stop.

Keep the whole world singing. . . .

Why do you particularly need an electric brake ?

That's fast. If it stopped much faster, the torque would make it leap
out of your hand. There's also a problem with heavy blades tending to
unscrew if stopped rapidly, which is the root of the whole "no dado
blades in Europe" issue.
>What should be the typical time necessary for the blade to stop.
The UK regs (which are applicable across Europe) are that is must stop
in "a sufficiently short time", defined as under 10 seconds.
Some notes on this, particularly retrofitting braking to old machines,
are at:

The list (and whole site) is interesting reading.
