Making Quarter Inch Router Cuts

Video Transcript

"Now that we've cut a 1/2 inch 1/4 inch deep slot I've changed the bit in my router to 1/4 inch bit instead of a 1/2 inch bit. We are going to cut down the same line but we have to readjust the router now to cut all the way through this piece of wood but we can't do it all in one pass so we're going to do it 1/4 of an inch at a time, so we're going to reset the router which is now set at 1/2 inch, I'm sorry, I mean 1/4 of an inch. I'm going to rest the router now to 1/2 inch, set it right back where it was and make the first pass in cutting this slot and that is going to let our carriage bolts and hardware go through so we can so we can attach it to the miter guide. Okay there is our first pass. Now in a perfect, perfect world, this slot, the 1/4 inch slot will travel precisely down the center of the 1/2 inch slot, however, the world is not perfect so there might be a little bit of a variation here depending on whether your stock is flat, whether this line is actually really straight. You don't have to worry about that too much as long as this little assembly right here, the washer and the end of the screw carriage fits below the surface, you're fine and when we finish routing all the way through this piece of wood we'll set it up on our miter guide and if we have to make some little adjustments so be it, it's just maybe a little filing or a little bit of sandpapering. You're going to find that using this jig is going to require several instances where you kind of have to tweak it a little bit. It probably won't come out absolutely perfect your first time. So now I'm going to finish cutting this through and when I get done with that we'll start fitting it to the saw."
