"A tour with Beth of the features and benefits."
   A step-by-step of changing bits...continued

With the bit "bottomed", she pushes in on the shaft lock knob and turns the bent wrench until the bit is locked in the collet.
	She places the smallest insert that will give the bit proper clearance.    Question: can you  identify what the bent rod in the foreground is for?
Beth starts to change router height. She turns the remote height adjustment lock 1/4-turn. The rod with the white knob is the adjustment crank for the RouterRaizer™ that I installed last week. (Click here to go to that section.)
	This is how easy it is. With the shaft unlocked, she uses the crank to adjust the height of the bit to match the sample that she has been using. When it is right, she simply turns her right hand, and locks the shaft.
The RouterRaizer has a small metal dust cover which fits into a hole over the access to the height adjustment screw. The crank has a small magnet which is used to remove the dust cover for easy access. It stays in place on the magnet until the height adjustment is complete, and it can be "swiped" off as easy as it was to pick it up — a very neat and workable device.
	With the bit changed and the height set, Beth double-checks to see that the shaft lock is disengaged. She now unhooks the plug from the knob.
She plugs the router cord back into the switch box. Note that the power cord for the dust collector is also attached and is switched on and off with the router.
	She places a brand new insert into the fence slot. The junior raised panel bits are ones that benefit from using a zero clearance insert plate, so it is worth the effort to make one.
She starts to cut the profile in the fence by easing the fence into the router with the router spinning. She is careful to stay behind the fence for this operation.  The fence is pivoting on the end with the adjustment screw. The pivot pin is retracted for this cut.
	With the router stopped, she marks where a space for the bearing and top nut must be cut.
Cutting the insert to her marks is quick and easy.
	With the insert cut to allow for the bearing and top nut, she can complete routing the zero clearance fence.    She will loosen the entire fence slightly and move it and re-cut to widen the opening. The insert should be loose around the bit. I prefer to cut it until I have about 1/8" all the way around the cutter.    [Note: before turning on the router, always be sure to rotate the bit by hand to ensure that the cutter clears the insert.]
Beth brings the fence forward until the bearing is absolutely aligned with the fence and locks the fence in place.    She is ready to make her cut.  On the last two pages, I have presented the step-by-step in great detail. In real time, changing of the bits takes about 1 minute, even with following all the safety rules. Cutting a new insert takes a couple of minutes longer, but only has to be done for a new bit — and then only if you want a zero clearance insert for that bit.
