I don't understand the 2mm from the string part.

Hi The technique relies on measuring the distance between the string line and the oak. I place my pencil behind the string and estimate the distance from the string to the timber. I admit I should have explained this better. Alternatively You could use a ruler to do this then simply read off the measurement. In this case the string is 2mm off the timber. So then I replicate this 2mm off the string when I make a mark the other timber. It takes 2 marks (1 at the top and 1 at the bottom of the timber) then you can draw a straight line between them. Does that explain it? To expand on this idea if the face of the top timber is 2mm off the plumb line at the top and 2mm off the string line at the bottom then the face of the top timber is plumb. Alternatively if the measurements are 1mm and 4mm off the string then the face of that timber is 3mm out of plumb.

So you have a 1mm or 2mm or whatever size pencil and you use this to eyeball the 2mm gap that you talk about in the video? So it's like one pencil width plus a smidge top and bottom and you're good to go?@@PostandBeamUK

Sorry, tried to comment but something seems to messed up... It's a great basic video for this method and thank you for sharing it. I'm pleased the next generation is keeping these traditional skills alive. I am wondering, as a business, if this much more labor-intensive method of "scribe rule" is worth the effort as compared to traditional (and virtually as old)..." line rule"...methods found in Asia that achieve the same results with organic shapes yet do not require the test fitting nor material handling of scribe rule? Looking forward to seeing more...

Scribe rule (the traditional method, dating back to the early 1200s!) is much more labour intensive than square rule (made much more famous by a lot of North Americal luminaries, like Jack Sobon). I love scribe rule, and have done plenty at Weald & Downland with Joe Thompson, but the Line, Level & Plumb stuff takes ages and means each scribed timber can only go in one place, and one place only (hence Carpenters marks!). Square rule is great cos it makes sense, is comparably easy, and whilst layout can be a ballache, you can make all your timbers in one small space, various bits can be interchangeable, and you don't have to lay all the components out as they will go together in the finished building. Having said all that, there is something joyful about getting a Jowl Post/ tiebeam\plate lap dovetail joint precisely right with such simple tools as a plumb bob, pair of calipers, scribing tool and a two-foot stick.

@@nigelsansom2407 Hello Nigel! Thank you for your comment. I should have validated that I have been an apprenticed Timberwright since the age of 13, accumulating over 40 years of practical experience, with the last two decades dedicated to teaching on various projects. I have met Mr. Sobon multiple times during my more than two decades of residence and professional practice in New England. I have greatly appreciated many of his coauthored works, particularly the "How To" instructional texts. However, I have observed that certain viewpoints presented in his writings tend to reflect personal opinion rather than strict historical accuracy in regards to layout modalities. It appears that he has revised some of these viewpoints over time. The claim that the "scribe rule" emerged in Europe in the 1200s is inaccurate. While the precise timeline remains ambiguous, evidence suggests that this practice extends back more than 4,000 years, with the Shang Dynasty (1600 to 1050 BCE) as an example, employing both "line rule" and "scribe rule" techniques in their timber framing systems, which were further regulated by building codes and great complexity. I agree with the assessment regarding the development of the "mill and edge rule" system, which, while similar, exhibits distinct differences; one necessitates meticulous planning and geometric precision, whereas the other is applicable to hewn timber. Current historical evidence suggests that these systems are less than 400 years old and represent a simplification and assembly line approach that emerged from the shipbuilding industry, aimed at the mass production of structures featuring interchangeable components. Unfortunately, this system limits creative expression and the use of "live edge" timber with asymmetrical geometry, which the "line rule" accommodates with significantly less effort. It is important to express my admiration for the various historical iterations of the "scribe rule," as well as the more sophisticated version presented in "L'Art du Trait" (also known as Stereotomy). However, it is worth noting that these methods require significantly more labor compared to the Asian "line rule" systems, which can frequently accomplish similar intricate geometries in timber framing, including the integration of live edge timber work. From a commercial business standpoint, as younger Timberwrights enter the field, there appears to be a growing inclination towards the "line rule" systems. This trend may be attributed to the influence of the internet and the appreciation for Japanese and Asian architectural styles. The appeal of these "line rule" systems lies in their inherent simplicity and logical structure, which facilitate both efficiency and creative expression as compared to the other systems of timber frame layout. Thank you once more for your comment...
