The hand wheel needs the dremmel just like Steve said. The needle bar is caked in oil, not rust. Oil will clean it off - so will some solvents but the solvents will take off paint and go places you don't want solvent. I cut a long thin piece of t-shirt and kind of floss around the area with oil or solvent... Depends on if the oil cuts it pretty good or not. Then use a bit of Tri-flow... I should buy stock in that company...
