Bruh I'd lose my mind and my wallet in that bin

Two out of three sticks coming back to life is a great hit rate, and I bet that felt good. I ran a shop years ago and we saw this all the time on machines from coastal towns, the salt air just eats those contacts alive. What got me was how many people would toss a good stick or pay for new RAM when the fix was sitting in a desk drawer. The eraser trick works, but you have to be gentle with it so you don't rub off the thin gold layer. A little isopropyl on a coffee filter works too when the eraser leaves residue behind. Sorry you had to learn it the hard way on your own dead sticks, but at least now you've got a trick that saves you real money.

Worth pointing out that dunking the brick helps because the brick itself pulls water out of the cut, not because the saw lacks water. The blade sits in a bath of it, but a dry brick will suck that moisture right out of the kerf before the blade finishes passing through. When you give the unit a head start, it's already soaked, so the blade stays lubed the whole way. Duane was dead right, just not for the reason it sounds like.
