 A three-minute overview of how to use the Bosch Colt plunge base. The first step is to take this little micro-adjuster right here and turn it so it's got a little gap here. In other words, we don't want that all the way up to the top. If we have it all the way top, then we won't be able to do a micro-adjustment later. All right, with that in place, find the lowest spot on your turret and get that underneath the rod. Plunge your router down to the top of the workpiece. Push the rod down, you might have to loosen this thumb screw. Push the rod down to where it's touching that bottom plateau. I would tighten it for a second so that you can move this plastic guide without moving the rod and line the plastic guide up with zero. Loosen, pull the rod up to the depth of the cut that you want. So if you're going to cut a depth of three-eighths, pull it up from zero to three-eighths. You pulled up the rod, not the plastic. The plastic stayed where it was. Lock that in place, raise it. Now you're ready to do a cut. Now because we're on the lowest one, that would be our third-eighth when we do a route there. If I turn it one, that would be our two-eighths. If I turn it one more, that would be my one-eighth plunge. I turn it on, I plunge it down until I hit that platform. I do my routing, I turn it off, I bring it up. You don't want to be trying to change this turret with this router bit spinning right there by your fingers. Turn the turret to the next step down. You start it when it's up in the air, plunge it, do your routing. Turn it off, release it, turn it to the lowest spot on the turret. Turn it on, plunge down to that final spot. Do your routing, turn it off, and bring it up. Those are the steps. Small workshop guy, signing off.
