spring is here. lots of building is going on. so go out and tune-up those tools. i found the anti-kickback device on my table saw wasnt in alignment with the blade. my chop saw wasnt aligned at the 45 deg presets. dust cakes were found clogging air vents on motors. go buy some new dust masks. for the new DIY'ers DO wear those masks, dont worry about looking silly, use a magic marker and draw some mean teeth on them, they are good, mdf dust is bad. anyone have any other tune-up tips?
