 the Bosch Coat Plunge Base Micro-Adjuster. What we're trying to demonstrate here is using the micro-adjuster for a really small plunge. So I've got my router bit in that I want to use for this particular dado. I want it to be less than an eighth and so to do that I can use this micro-adjuster. You turn it a few rotations clockwise but not so far that it falls off the screw. So you've got it so you have some room to turn it back counterclockwise. Steps would be to plunge down to where your router bit barely hits the top of your workpiece. Don't press on it or anything. Then loosen this and push the depth dot rod down so that it's on the very bottom plateau of the turret. That would be what we would call our zero position. Now if I want to do a one-eighth cut then I could use the turret because these are one-eighth steps but let's say I want to do a one-sixteenth cut depth-wise. Bring it up and I'm going to rotate this. Each complete rotation in a counterclockwise position will raise this by one-thirty second of an inch so if I want to do one-sixteenth that's that's two-thirty seconds so I'm going to go around twice. There's little indicators on it that are each quarter or each ninety you know one-quarter of the way around so those would each be one over one-hundred and twenty-eight as far as a portion of an inch. So I want to go I'm going to try to do a one-sixteenth cut so I'm going to rotate this two complete times so that's quarter, half, three-quarters, one quarter, half, three-quarters, two. Now let's raise that by a sixteenth of an inch so when I do my plunge it should be a sixteenth of an inch deep because it's let's give her a go. My only purpose here was to demonstrate this little micro adjustment device. You could obviously do that same depth of cut even with a fixed router you don't have to have a plunge router with any kind of a device just to set the the depth of the bit.
