- Mo'better ideas for adding an emergency shutoff to your Shopsmith and other stationary tools. If you missed the prior video, catch it here: • This has got to STOP! ...
🛒 Here's the switch I would reccomend if you can't wait to find a Shopsmith switch, or if you just like stop signs! amzn.to/4apXNpO You'll see lots of similar switches on Amazon, but this one has the longest cord and is appropriate for 15 amp motors.
🛒 This is the large rare earth magnet I added to the switch: amzn.to/3xB8wPm
🛒 This is the all-metal Wen momentary on foot switch: amzn.to/4cMsNlf
🛒 This is a generic (non-Harbor Freight) version of the magnetic paper towel holder: amzn.to/4cHbgL5
🛒 Search eBay for "Shopsmith SPT Switch" for listings. "SPT" stands for either "Single Purpose Tool" or "Special Purpose Tool". Shopsmith Inc used both definitions and the creator of the SPT's didn't use the acronym at all, so take your pick!

The term “magnetic switch”, or similar terms, usually refers to a No Voltage Return (NVR) switch. What you are calling a “magnetic safety switch” is most definitely NOT an NVR switch.
An NVR switch ensures that when the power goes out and a tool was still switched “On”, it will NOT suddenly, and unexpectedly, resume running when the power is restored. Obviously, that could be very unsafe. Instead, an NVR switch must be moved to the OFF position, then back to ON, after the power is restored. It keeps restored power from reaching the tool’s circuitry, or “returning”, until the switch has been reset, hence the name No Voltage Return.
NVR switches appear to be used more in industry and in European power tools, than in American power tools. I would LOVE to have NVR switches for my power tools, but the ones currently available to consumers (woodworkers, wood turners, DIYers, etc) in the US generally do not handle enough amperage.
Tip for power tool users: NEVER leave a power tool switch in the ON position when the power goes out. You do NOT want that table saw, circular saw, router, etc to come back to life unexpectedly.
PLEASE refrain from calling a refrigerator magnet version of a switch a “magnetic switch”.
Yes, upon rewatching myself after this went live I realized that what I was saying could be misconstrued as me saying it is a “magnetic switch”, which is most certainly is not. Thanks for catching that.
I have found such a switch, on sale for about $30. I use in on my two 10 ERs and router table. Nice big panic button and it goes to off if the power cuts off.
@@edwinfriedl2446 Where? Brand? A link? That would be most helpful and appreciated.

Hi Scott, Love the video! And you cost me more money! Just kidding, when the parts arrive, I feel I will have a safer shop!
Happy to hear it, Albert. You'll like it.
Thanks for the follow up video. I really like that switch option. I 100% agree that a foot switch is a bad idea for a spinning tool, but I love mine for my dust collector. I recently upgraded to a wireless remote switch which I like even better.
Good insight.
I haven't seen a need for one of these. I have a remote for my dust collector that hangs on my shop apron but I haven't needed a reason to do an "emergency" stop to my SS.
the big paddle switch is the best looking solution, no not pretty, but practical, just a cranky old mans opinion that started using power tools in the '70s that still has all my fingers and no nails sticking out of my head from using tools without all these new fangled safety things
Yes Scott, that's exactly the switch, magnet and position I have on my 510.
Great informative video! I use the "stop sign" style switch on my lathe and router table so I can shut off with no hands if needed (with my knee). I use the momentary pedal switch on my drill press and small metal cutting band saw (I accidentally step on it a lot! - but pretty harmless on those tools). Hands free power on/off on the drill press is pretty nice
Not mentioned in your article is the fact that the paddle switch can be shut off with your knee or hip if both hands are occupied. Take this into consideration when deciding where to place the switch.
Nice comprehensive overview of safety switch alternatives. Thanks
Glad it was helpful!
Well, bless your heart, Scott. It never occurred to me to pursue this option. I remember in an emergency situation yanking the chord out of the wall. The last switch you showed is my next upgrade ♥️👍
Excellent commentary. Your presentation of foot switches, even though you don't use them or recommend them, speaks to your impartial presentation of all things ShopSmith. Thank you Scott!
For me, the big slap-em STOP switch with the magent makes the most sense.
Thanks for that, Mark.
Another excellent video. I have the same concerns about a foot switch. I have been using the paddle switch for nearly a decade and it is really handy.
Great to hear. Is it this one or one like it??
@@MyGrowthRings I actually have two. One is identical and the other has a rectangular paddle. They work equally well.
Really like watching your videos, very informative. I am thinking about adding a "momentary on" foot switch to my Shopsmith. But the one I have in mind is the safety type with a guard where you have to stick the toe of your boot in to activate. The same as are used on Pipe Treading machines. I like the "Dead Man switch" option.
I do like that combo. Be safe.
When I mentioned a footswich before, I purely meant for an emergency power off option that I could move around the room. Thought being I would rather have both hands available to continue holding what I need to hold, maybe letting go of a piece of wood to press a button would allow it to become more dangerous then holding it in a position until the machine has stopped. That's where a foot stop would be priceless.
If I accidentally turn it off... Not a big deal.
I still think a nice big latching button on the wall that cuts off all the outlets in the workshop is the best way for a backup emergency safety switch. Mine trips the RCBO (combined GFI and MCB) supplying the workshop outlets. It's a big red domed switch on the wall with the words emergency stop printed on it. Pressing it connects the neutral to earth which trips the RCD.
Great video, thanks for the time you took. Maybe someone addressed this but i don’t think some of them will work on a mark 7, you would have to set it back up after using the switch. I do like the last one. Seems like a great solution. Also very cool seeing my name on the chairman list.
Tim, I've mentioned that very thing in several of the comments, but you are right. For you and others with the PowerPro headstock I wouldn't use this switch for everyday on and off, but it would still be a good emergency off switch. Thanks for the support! Scott
It's clear there's still a need for mechanical switches. I just had a horrible mental picture of a runaway machine and a hapless user shouting, "Alexa! Tell Shopsmith to turn off!"
That's true, and it wouldn't surprise me to hear that something like that has happened.
For many years I used a foot switch with a cover plate to prevent accidental turn-on. This switch had a small red side paddle that released the main peddle switch. The problem was that often, when I needed it, the location of the off-paddle was not in my line of vision. I just ordered the paddle switch you recommended but without the box and cord. (cheaper that way) and it fits inside a standard shallow outlet box ($1.04). I will then wire a new 10ft. 14 gauge extension cord into it and place rare earth magnets on the back. This makes a much less bulky package than yours and, I think, less weight and less tendency to slip down the metal face of the machine. Just another way to skin a cat:-)
There obviously is a lot of value having the power switch handy while using the tool. However you do it make it reliable and easy to use. I could see the big red paddle switch useful on a vintage tool built before safety standards.
I used the Rockler version on my '81 Shopsmith for about 15 years. I screwed it onto the headstock where you used the magnet. Worked well and had no issues. Alas, I no longer have that machine but own a '56 version without a separate switch.
That would be a MUCH better switch than the old toggle switch on that headstock.
Dennis. I think you might enjoy this intel. When you did your video on adjusting/installing knives on the SS jointer. You introduced the SnapCheck iGauging digital read for setting up your knives. iGauging now makes the Snap-Check Pro. This is now a dial gauge measurement and the body of the tool is aluminum and not plastic. In my opinion at $50 bucks on Amazon is a far superior measurement tool. I work in a wheelchair and have a pretty fair shake in my hands. The dial is WAY WAY easier to use than the older digital read. Yes it has the same (3) measurment. Inches, MM, Fraction. Take a quick look!
Thanks for the heads-up. BTW, who is Dennis?
Many years ago I watched the Shopsmith demo team using a push on/push off foot switch as part of the act.
Hopefully it was with the dust collector. Yes, we sold a switch. That’s almost identical to that Wen switch.
@@MyGrowthRings Yes, like the Wen. They used it for the head stock. Very convenient for the demo as they could keep both hands going on other stuff but they never drew attention to it. It was in a shopping mall in the 80's.
Scott, great video! Thanks for doing all of this research. The price for the switch and magnet appear to be well worth the improved safety factor!
You are welcome and I clearly agree.
Not really sure if I remember the original point here (I thought it had to do with turning the machine on/off without having to walk around it), but I would mount that Wen switch on something in the vertical position so I could hold my toe against it in my working stance. If I move my foot for any reason it shuts everything down.
It'd be easy enough to make a thin "L" mount out of whatever, but these days I would probably just 3D print something for that.
Having to stand with one foot on a switch is a no-go for me; I don't even use guitar pedals for that reason.
My next choice (strictly for operation) would probably be those remote switches that a lot of people are using for their dust collection, but that might not be great in an accident situation.
The dead-man switch on a bracket would be easy enough to move around from here to there and would cover the main concerns, I think.
Yes, the original point would be to have that switch available on the end of the machine, when turning or when running a SPT (special purpose tool), but mounting it on the headstock as I have is a much more prominent stop when using the machine in many other functions. The point of having a switch on a magnet means I can put that switch anywhere it is convenient for me. Scott
i us the foot one on the drill . using a hand to hold and one on drilling i need to us my foot
Think through the probability risk before using those "gun magnets" for their intended purpose. I got a few & they're great magnets, but no way they hold gun if in a car accident. I don't want a gun ricocheting around inside the car. I repurposed them for creative in-home placement & also for tools in my shop.
Can you please address the easy lift system and how it works for both directions of lift for a MK 7.
Thank you very much.
Mike, I have the lift on my 510 and really like it, but since I don’t have a Mark 7 I don’t need the double tilt version. If you have a PowerPro headstock, which is standard on the Mark 7, I don’t know how you can live without at least the drill press version. The left tilt isn’t as critical since the weight of the headstock stays low.

What about electronic, wireless switches?
The main idea here is an emergency shutoff for a 15 amp motor. Most of those switches are rated for fans and dust collectors that have smaller motors. I haven’t found one that would work or that I would trust for an emergency, but I’m open to it.
Why is it an issue to use a remote switch with a Power Pro model? That's what you said (or I lease what I heard) in an earlier version. I know the ShopSmith manuals warned you to reduce the speed to its lowest setting before stopping in order to avoid damage. But with the Power Pro, you can stop anytime. So I would have thought the remote switch was a bad idea for the old models and not the Power Pro.
Stopping a PowerPro by cutting the power to the headstock will cause the computer to reset, and this is not the preferred way of turing it off.
Reason being that when the PowerPro powers off, has with a remote switch, the PowerPro comes up in an idle state as when you normally power it on. A safety factor in itself. Nevertheless whatever settings you were running would have to be reentered. Whereas with the standard headstock it would power on as it was last set up.
@@dwightl5863 Thanks!
I found both items the paddle switch and adhesive gun mount on Amazon. Thanks for the review, I am happy to add it to my standard safety equipment on my MK 7.
