plunge router issue / advice wanted

[Pete Duffy]

New guy here chiming in with my first post. I have the Bosch 1617EVS-PK and love it. It might not be the HP you want, but it is smooth in all respects. It just feels great and is a joy to use.

I do the last part of this procedure just a little differently.
I screw the plate to a piece of scrap large enough to clamp to my drill press table after making sure the bit will be 90 deg.
Then I bore the small hole all the way through. Change the bit while not moving the plate.
Next, I bore the large hole halfway through the plate. I check with bushing that the shoulder is slightly below the base surface.

That works too. More than one way to defur the feline.
