" Now these shelves were made purposely a little bit smaller so that we have some left over space at either end for fitting, right?"

" That is right. Because most walls are not [unk] and this one isn't."

" How much is it out?"

" It is a quarter of an inch. An inch and five eights in the bottom and an inch and seven eights on the top."

" And so what do you do?"

" Well, while we deal with that, is we will put the material right up against the wall and secure the bottom."

" And what we want to do is we have 2-3/4 of an inch of waist we are going to be taking off but we want to set the top and sand this."

" Yes."

" And tap that into place."

" Yes."

" And then"

" Now I have come to the carpenter's favorite tool, this is the scribe."

" You have 99 cents to have a scribe"

" Which kids in school would call compass. and how do you use it here?"

" We will set this in the distance of the waist on the back, right there. That is 2-3/4 of an inch. Just take it and run it along the side of the wall making sure that it is level."

" Making sure that you keep that point right against the edge of the wall and that is how you are going to get your cut line. Alright, this is a straight enough situation that we can probably cut it on the table saw, right?"

" Yes, that is how we cut on the table."

" Because you can do this the same way if you are up against a stone wall or brick wall to describe it but then you have to use table saw. "

" That is right."

" Alright, while we run this through the table saw, we are going to show how these shelves were made back in the workshop. We are making the bookshelves out of this beautiful birch plywood. The back, two side pieces and of course the top piece will all be joined together with Rabbet edges and you can make the lengths on the table saw and the shorter widths on the radial arm saw. Okay, now we will join the sides and the top. A little bit of carpenter's glue always helps and we are using drywall screws to put it all together and of course it also helps to have a little pilot hole already drilled where it is coming together. Alright and we will flip it over so that we can attach the back. And first let us put some glue on that Rabbet and then we simply use 4-penny finishing nails."

" That is right. Hold it."

" It is coming to you."

" Okay I got it."

" Now the main thing that we want to accomplish with bookshelf is to have adjustable shelves and so we have created a storey pole for ourselves with this drift of plywood and all these holes are 2-1/2 inches apart and the piece of wood itself is 2-1/2 inches and so that when we put it here against the back or against the front all these pilot holes are going to be uniformly spaced. Now we will just a guide hole with an awl. That's how you want it?"

" That's good, right there. I put tape on the drill bit so it will only go in half of an inch and that is plenty of room for the shelf brackets. Okay, let's see how these little things are gonna fit in here. That is what makes them adjustable shelves. Okay let us do the other side."

" Okay."

" That looks good Ryan and now you are gonna do the same thing on the other side and then we will put a crown across the top. In the mean time, I have been putting some of our shelves in place which is the beauty of having all these variety of holes that you can put them anywhere."
