JJ, all my posts are long, (as well as my comments)... A lot depends on practices and druthers. I have found that when handling larger sheet-goods/timber especially during in-feed/out-feed, that 3rd hand foot is invaluable. I place a lot of emphasis on safety in the workshop, just ask any visitor, however, I'm sure we all conduct practices that we are confident with, that others on first (or more) impressions would cringe at. I'm sure many would freak out at me replacing that (actually several) machinery mag-switches with an ordinary toggle.
I posted this project moreso as it included that "button" controlled power-board for those that may not have a paddle for their machinery.... and the button can be paddled... as I have done for a smart in-line switch I use to turn the shop lights on, so it can be controlled manually or voice.
FAIW, I have temporarily (though it may become permanent) added another power-board into the chain that can be controlled by a remote that can be placed in any convenient place, Another practice many may cringe at... I use it extensively when I need to cut small pieces that are too small for my sled (gave away my small one), and being a short arse, my 4' 15" stature finds the small pieces hidden out of sight with my mitre gauge as I don't have the luxury of a good top down view once it approaches the blade. I stand on the opposite side where I have a full view of the blade and pull the gauge towards me. Having full view I can minimise travel and closely watch the fingers being still attached... just remember that you are in a workshop and not French court, and etiquette requires the pinkie not be stuck out.
If your first cut is too short... Take the second cut from the longer end... LBD
