    Trip bar for switch

    Here is a cheap solution to my safety problem. I'm not sure who else can appreciate this but here goes. Please keep the chuckles to a low roar!
    Now first off I know the reason the BT3100 switch is on the right side...because it was cheaper to put it there. However, it is in a dangerous place IMHO! It belongs on the left side so that you don't have to put any part of yourself in the line of the blade to shut off the saw.
    Yesterday as I made a cut with the SMT, the small piece of wood left to the right of the blade vibrated into the spinning teeth as I was reaching down to shut off the saw. Luckily it hit my gut and not my head, but it hurt just the same.
    So, I set out to devise a trip lever to shut off the saw from a safe position.
    Here is my solution. One piece of 1/4" x 36" aluminum rod, some hardware, plastic clamps and rubber tips. The switch pad is pushed to the off position by moving the rod from the left end, 2 feet to the left of the switch.
    Want more info, just ask.

      Hey Salty,

      I like it...a lot! That's a fine implementation of an important safety-generated idea. Can you say a bit more about your source for materials?

      Thanks,

      Dwight

          that is a good point! both of my table saws at work have e-stops on the front right and on the left at the edge of the table so that you can turn the saw off when you need to. our planer has an e-stop on the front and back.

                  Well, the t-nuts I made out of some 1/4" aluminum angle. T-nuts.com sells them too.
                  The rod I got really cheap from work.

                  Source for the blocks and the vinyl caps are here: www.dxengineering.com
                  Part numbers are DXE-VC-0250(vinyl caps) and DXE-RSB-I02500(blocks)
                  I clamped the 1/4" blocks together and ran a drill bit through them, a size just over the 1/4" of the rod. These blocks are made to clamp onto the rod or pipe but in this case I just wanted them to act as a pivot.
                  Smallparts.com has the rod for $2.50 but you will need to pay shipping on top of that. I remember seeing aluminum rod in the local hardware stores too.
                  There are other ways to create the pivot and rubber tape would work in place of the vinyl caps.

                  Hope that helps.

                          pretty slick, Salty. Will probably copy that idea.

                              Some other observations.
                              It does NOT interfere with either the SMT or the fence.
                              Also, it will not affect the use of my home-made miter slot.
                              The length will depend on the position of the front rail. I keep mine further to the left and have the fence marker on the left. And of course if the front rail is moved than this device will need to be adjusted as well.

                                      Nice soloution. Good use of materials I think as well.
                                      I always have a push stick in my hand and use it to slap the cover blindly so I won't be in the line of fire. Sometimes it takes ma a couple of tries. Not a prefect soloution for sure.
                                      One of the main reasons I think the switch is on the side it is is for use with the router table. I have a shop made router table wing on the right and the position of the switch is logical for that.
                                      I think the most elegant soloution would be a short cable with a remote switch that mounts on several locations as needed. When using the RT, you could mount it on the fence. It would need to be quick mount of course. Then you could move it to the left under the SMT for sawing. Still the switch, box wire and mounting hardware would be more costly.
                                      I think your soloution works the easiest cost wise.
                                      Thanks for posting this. I will be using the idea.

                                          I like that!! I am now using the router table switch from Rockler,m with some of Jeff's nuts. Works well, and I can move it to where I need.
