This one has been kiln dried down to about 9 % moisture content, and you can also see that as part of the drying process, we've got some checks forming in the ends that we're going to stabilize, but there are also somewhat some would call major Defects in here there's a there's, a big crack. You can see that we've got the backside of a knot here or a branch we're going to stabilize and highlight those defects. The goal here is to preserve as much of the natural character of this slab as we can.
The other big task is turning this roughly milled dried slab into something that's nice and flat and stable. You can see that it's rocking back and forth here and to do that we're going to use what's called a router sled and our router, it's a little bit labor-intensive, but it goes a lot more quickly than you might expect, especially on video, so stay tuned and We'll get going on that sled, so our router sled is made up of two parts.
We have rails and a carrot jenny's, as you can see here, for the rails. I've just got two pieces of lumber butted together here to make an L now for this lumber I sprung for the premium stuff. I wanted nice straight square boards because this is going to be a reference surface for the carriage that rides along on the top to give you a nice flat surface. So again, I just countersunk a couple screws a few screws in each one. I'm going to finish doing that and then move on to the carriage. So now that we have our rails assembled, we can work on the carriage I've already put together one side of the carriage here, so we can see how it works.
You can see. It's just sort of at-shape and that's going to contain the router as you're working, so the router will ride through the middle of this, and I conveniently I've put it together. So my base prevents the router bit from actually biting into the side of the carriage, and so we're going to do this on the other side too. One thing you want to keep in mind, though, is that your base may have an auxiliary handle or other things on it that could get in the way of your carriage. Your base could also be a totally different size. Our carriage is going to be about ten inches wide, depending on what router you have in what base and what bid you're using you may need to make some adjustments, so I'm going to go ahead and get the other side of this assembled.
We'll put on a couple of end pieces and then it's time to flatten our slab, so I've sized my carriage, so the fence is actually inset three-quarters of an inch from the end, it's crazy how that all works out. But that means I can use a couple pieces of plywood as a spacer in order to attach it all together. You can also see on my plywood. This is construction grade, so it's got one pretty good face and one not-so-good face. I'm going to use the good faces on the edges that connect with the router to make sure everything stays nice and smooth.
