Dutchy ..... On my table saw I use a non switchable one. Made for welding activities.
You're comment reminded me I have a couple of those magnets... bought long before I knew about Magswitch.
I can easily lift those up off the tabletop with one hand and little effort. I could not lift the smaller mag switch with both hands without risking a hernia. I could push the smaller one sideways, but I was fully aware that it took some effort... naturally the larger one (40mm) was much. much harder (to push sideways).... forget lifting. Warning:- The danger with them is that if you have them "turned on" when putting down on the tabletop and have fingers under them... you can remove, not skin, but flesh!... always turn on after placement.
If your first cut is too short... Take the second cut from the longer end... LBD
