- Agreed. If I sounded a bit nit-picky, it's because I think it is
- important that others not be misled; the difference in cost between
- a magnetic switch and a start-stop button that solves the "easy shut-off"
- probem could buy a very nice saw blade.
-
- While Steve Bellovin may know the difference, there is a significant
- amount of ignorance in the woodworking world regarding these switches.
-
- For instance, I tried the "big piece of scrap, start-stop button" on
- my Delta Contractor's saw, by using a different switch (I actually
- traded switches with my Jet Jointer). I found the arrangement not
- to my likeing at all.
-
- This weekend I bought some 12/3 extension cord wire, and ran the connection
- from my saw motor over to the wall, up it, and across the ceiling. Now,
- my switch hangs from the ceiling on a cable and can move around with
- the saw. It is totally out of the way, and no matter what happens, I
- can easily reach it. This completely solved the problem for me, without
- spending $80 for a magnetic switch.
