I have a Wood Pecker router lift from about 10 or 15 years ago, they don't make it anymore. It was untouched until about 3 months ago. Now the brass bushings on the 2 main guide shafts come out of the router body clamp. This means the lift has nothing stopping the router from moving side to side. I found this out the hard way and destroyed a piece of 12/4 hard maple for my work bench. I try to put them back in and as soon as I move the router up or down, they come right back out. Anyone else experience this?
