" What's the width of our. Area there we have an overall -- interest. Which is good even increment to work with so let's take the tape measure out a minute so that we can bigger. What you've done here you've got. Obviously your midpoint at forty inches exactly and then show me the rest of what -- they're pretty much on the side and lovable. On the sent -- forty and a half and you've divided this and you've come out eleven and a half inches exactly so that your your. Radius is eleven and a half which makes the whole thing here. 23 exactly. How did you determine that dimension for the for the half circle pretty much it's by. -- look at it we try to small one in there we go with the gables and yet you have to have a sense of proportion. So that here we go 23 and a half almost two -- And then that means these guys over here are just about thirty inches exactly. All right well I think that's the simple part of the deal hard part is figuring out how to make these cuts how to rip them up so that. You're not building up clapboards and creating. A thickness of clapboard on the wide end of the clapboard that would be. Beyond the face of this piece of half round I do that pretty much. We go with the thin end. On the inside near the -- If you did go with that -- by the time you got the -- you'd be sticking over probably an inch. So you're measuring from the thin edge of the clapboard and cutting off the thick edge right and of course we've laid out of the pattern here on felt paper. So the big question is how do you determine how many clapboard -- being used and what these dimensions are here at the other side. -- I do is I take my circumference from here and here. Yet -- that measurement. And I like to keep the courses around two inches and how nice that you like to keep now that's an aesthetic decision you're making there you don't want that many wider than about two sides. -- that works out to eleven courses. On this side we gotta go from the peak."

" Down to this corner yeah OK and then down from this point."

" They take that dimension. And divide it by eleven divided -- and what does that into in this case we have formed by -- weren't by the -- an inch and a half all right. Now let's create cut and also the next question is -- about the overlap you add an -- to each one and a half an inch happened overlap all right. So on the inside by the he had the moon we have an inch and a half so I add."

" Happening so that gives us two inches yet for a pattern."

" OK and these are what we said roughly thirty inches nightly and a little bit long you're making them roughly thirty -- fifty -- adult."

" Something like that right. And then down here we have formed by the aids from an attic have that."

" But like five enemy. Of the like that OK and then changes take any communities just a straight -- right airline -- In my."

" And ripped. And that. That's my pattern. O'Brien now you have to figure out how to make that curved cut where it meets the half circle -- that pretty much what I do Bob is I lay my piece on. I overlap the -- and I overlap like half moon here yeah and I take my pencil. And I draw the mark and you transfer the -- pretty much free hand free hand ago and I take my. -- And sometimes you -- Play with a few times but to get nice and square yeah and then what about the other end and let it overhang -- like this. And mark here. And under the rake you have about three quarters of an inch of play. So I just mark it long and it doesn't have to be a tight fit now because it's sheltered by -- from the weather and everything else in this great. So I flip this over. I do first is like pat -- We tried again. And there's a place. Brian that really looks terrific now do you really have to have that white parting bead in the middle there yes but you don't if you didn't go at this. -- you have to clapboards butting together. And that's a perfect situation for water. The image you know not that can happen now definitely not."
