I use a mechanic’s speed handle like this one with a socket on the end. Hard to get faster than it is. https://www.harborfreight.com/38-in-Drive-Speed-Handle-62700.html
Me too. I have the 890 base on my router plate, and I never use the knob. It is faster to flip it out, change the bit, and snap the plate back in. The fixed base does have an adjustment knob on it that I can tweak from under the table. I have to get down on one knee to 'sight' the bit to whatever I am trying to adjust to, so I am already there.And I just lift my router plate and router as one unit. Do whatever, and put them back. Never could see why people like router lifts.
