As I reread my prior post on the sawstop a few things things come to mind.
The brake is triggered by contact with a living thing. If you are not gripping the hot dog, we taped one to a board, the saw will cut through it. It has nothing to do with grounding or the meat.
It is triggered by capacitance of your body, that contact and it is very slight, pulls the voltage down, because there is voltage on the blade through the arbor – not a simple thing to do – with very little current behind it. The voltage drop is what it senses to go off.
I believe false triggering wet wood nails etc. only happens when the operator in the, case of a nail, is in bodily contact with it when at the same time as it touches the blade. The saw then thinks is was touching the person. However it seemed that if a piece of very conductive material, such piece of the nail, was in contact with the aluminum brake it would also set it off.
We reported this to Sawstop and they concurred after testing and new brakes now have the tape on the surface in the form of a transparent sticker. If you own one ask to look at a new brake and see for yourself. A strip of packing tape may prevent a false trigger.
If I remember this right, and I might not, set a piece of wet wood on the table and slide it up to the side of the blade when testing. If I remember this right the light would go off if you took your hand away. Again it was the operator the saw was sensing through the conductive material.
Don’t test the using the tips of the teeth on a new blade, they are often coated with a varnish and prevent conductivity, when testing always use the side of the blade.
As for the standard contractors saw that is the one I bought and yes I would like it the be heavier, but I have it on the wheeled worksite cart as I move it to the job site. When in place I sandbag it to make it more stable. I wanted the light weight version, as you add longer tables and cast iron it becomes less portable.
1.75 is all the horsepower you can get from 110 volt. The sawstop delivers it well. I find it more than adequate for any task as long as it is not on a hundred foot extension cord. I bought my son-in-law an industrial version, he is a finish carpenter and he loves it in his shop and has yet to set it off in 2 years of use.
Hope I have clarified some thing for you. Sawstop is like insurance nobody wants to pay for it in advance and if you don’t have it when you need it you hope you can stand the loss.
It used to be that if you worked where you filled out an incident report or made up something like it when the brake was triggered, in other words it saved someone, sawstop would send a free replacement. After all they wanted the statistic. I don’t have personal experience, but I would try.
