As an addendum to the router table project; this is the shut-off bar installed on the table saw. It’s the same concept in that you can reach the bar with your knee anywhere across the front of the saw. Just copper pipe, some all-thread, a couple pieces of angle, paint and pipe insulation.

Nicely done .
One issue I have run into is that a unintended shutoff happens when leaning over the saw at times and have had the same comment from our local college instructors .
I don’t know what the answer to that would be to correct this other then moving the bar further inward .
I have looked at many different configurations from foot switch to paddle on the switch .
All in all a good idea .

Yeah, I’m in the same camp as kiefer. I shut my saw enough by leaning into the OEM shut off switch as it is.
I think it’s a great idea as long as it’s far enough under the front to avoid bumping it unintentionally.
Looks good though, how long have you had it?

Nice…

To prevent accidental shut-offs, you could shorten the “punch” pipe and use some type of limiter at hinge points to keep bar from swinging out as far…basically leaving it angled in toward saw a little.

very nice. I have seen commercial versions that didn’t look that good.

Looks good.

How does it work from the far side from the switch? I tried prototyping one using a push button after market power switch and found that worked fine when close to the switch but if I tried hitting the bar from the far side it would bind.

That is a terrific idea. I keep fumbling around trying to find the off button on my saw, especially when the fence is covering the switch.

Thanks for the comments and to answer a couple of the questions: I’ve had the bar on the table saw for at least a decade and only occasionally run into the issue of accidently shutting it off while leaning (probably too far to be safe) forward. The bar hangs straight down, at a right angle to the table top due to the length of the “punch” pipe. On mine, the foam pipe insulation sits about 1” ahead (before? in front of?) the front of the saw’s front edge. The switch, which I got from Grizzly, is quite sensitive and only requires a slight bump from the knee to turn off the switch. The pipe is 3/4” copper with a piece of 1/2” all thread running through it so it doesn’t flex or bind at all. I’ve been very happy with and as I said in the router table post: I love that I don’t have to divert my hands or eyes to shut off the saw. Much safer. Thanks for the feedback.

Great idea!!!

How close do you get to your saw that you would be constantly hitting this? The front of your blade is approx 12” in from the fence so unless your arms are unusually short I am not getting how this would interfere with normal cutting? In order to use a regular shut off you have to raise your knee not lean into it.

What college informed you of this? No bash I am just curious as to their thought process. You accidentally hit a shut off and…... what danger occurs?

The trend here is to dislike any sort of safety device but for me the one in a hundred times that it might accidentally shut off a cut is worth the extra safety during the 99 other cuts. Great idea and for someone who is always fumbling for the off switch like myself it will soon be added in a close form to my saw. Wish saw Co would step up with some modern safety features of new saw buyers.

”How close do you get to your saw that you would be constantly hitting this?”

I lean on the front bar almost every time I use my saw. I’m 6’ with long arms. I can’t clear the material past the blade without leaning on the front bar, especially when I’m trying to clear an 8’ long pc.
(Not to mention my 55 year old six pack)

”In order to use a regular shut off you have to raise your knee not lean into it.”

My off switch is even with the front bar, I don’t have to raise my knee to turn it off, I lean into it. Much quicker than reaching down and letting go of the work pc when something irregular has happened. I like to stay in control of the material. (Which is why the OP bar is a good idea, AS LONG AS YOUR NOT ACCIDENTALLY HITTING IT)

”What college informed you of this? No bash I am just curious as to their thought process. You accidentally hit a shut off and…... what danger occurs?”

The college comment sounds like a bash to me!
When the saw gets turned off in the middle of a cut you have a natural reaction to turn the saw back on. The change of body movement could lead to a kickback and/or worst. You go ahead and use your saw anyway you want though.

”The trend here is to dislike any sort of safety device.”

I’m not seeing this trend.
I applaud safety devices. I mentioned to the OP that this was a great idea, as long as it works with you.
If your accidentally hitting it while your cutting, it is not working with you.
Obviously it works great for him.
