Got a router table with a used black & Decker delux router model 7616 tonight. bought it from the neighbor for 35 beans, problem is when i turn the router off and the motor is winding down the motor sounds kinda rough(grumbles) this is an older router and the collett area looked a little dirty(rusty) i cleaned it up but still grumbling. I have never owned an older router is this common or does it sound like a problem? If so can you think of what and a soloution....Brushes? bearings? can it be fixed???? truth is even though it's a cheaper router it feels as bout as good as any router i have ever handled(think i have cheap taste or something) anyway if at all possible i really would like to salvage the router even though i only gave 35 dollars for it??????Please help all knowing ones
