I have a ten year old (weekend warrior duty) DeWalt 733 lunchbox planer that has served well, but is getting very "cranky" (sorry for the pun) in its old age. When I try to lower the head below 3/4 inch (funny it sticks there, huh...) it gets really hard to turn. It will raise up easily from any point, just gets croctchety down low. gosh, it sounds like I'm talking about myself trying to get up out of a chair these days . I have lubed the screw mechanism with spray-on white lithium grease, but it didn't help much. I'm wondering if the springs are getting brittle.
BTW, I'm too broke to spring for another planer right now.
