My point was that the user would have to be very careful and/or skilled, which they must have been. Sorry to come off as argumentative. That was not my intention :)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8118094056356737952.post-50846025186094319362019-03-18T21:08:32.114-04:002019-03-18T21:08:32.114-04:00So what did we do before we had tape measures?

Good photos of this practice are included in this article: https://www.finehomebuilding.com/membership/pdf/15429/021148064.pdf.<br /><br />My thought was, if you tried to do that with a material that stretched (like string, twine, etc.), you might not get a true semi circle. But, as you say, the results can be checked and trued by measuring the diagonals of the resulting rectangle.<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8118094056356737952.post-63838200007047242852019-03-14T22:06:42.148-04:002019-03-14T22:06:42.148-04:00Frames were and still are 'trued' by check...Frames were and still are 'trued' by checking the diagonals - they have to match for the rectangle to have 90* corners.

The next set of dimensions would start with the existing. <br />Foundations are set this way today, using cord, pegged.<br />A rod is not as easy to swing. It is better for measuring end to end - 10' rod x 2 for example was a common cabin dimension. Rooms were often 16' x 16', or 2 length of an 8' rod. <br />If you look at the initial layout for the cabin you see that the cabin depth is the radius of the circle which the arc is part of. It would be the fixed dimension - the beginning.<br />Janehttps://www.blogger.com/profile/03960577578174018923noreply@blogger.comtag:blogger.com,1999:blog-8118094056356737952.post-14740333429047546882019-03-14T10:57:07.380-04:002019-03-14T10:57:07.380-04:00Or maybe when you write "swings his cord"...Or maybe when you write "swings his cord", you are referring to swinging the rod??Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8118094056356737952.post-22340848914104225662019-03-08T11:52:45.476-05:002019-03-08T11:52:45.476-05:00Very interesting!!
