I made a couple of improvements. I added a spring to keep the push rod against the actuating lever and a small screw behind the spindle lock lever to keep it from moving too far back when the router was lowered.
I designed my router lift to allow above table bit changed using two wrenches. That worked pretty well but the Porter Cable wrench would occasionally bind on the bottom of the collet, making removal difficult. I decided to use the stock spindle lock instead. I just needed a way to engage it…
