pondering drafting and other "old techs"
Greetings
Was pondering the whole "it is good to learn the manual skills first" school of thought, and made the analogy to writing vs keyboarding. Not a smart statement to make in the hearing of an early childhood education specialist B-). She pointed out that children at that age learn "though the hand." They need to use their hand to make the shape as part of how they learn the letters. "So much for that idea." OTOH, for the vast majority of users, be it word processing, CAD, machine operator, operating an automobile, microwave, etc - knowing the history beyond the very basic outline is not needed. As far as keyboarding goes, all you need to know is "the layout is a legacy from the early mechanical typewriter layouts." Same with drafting - you don't need to know how to set an ink pen in order to use AutoDesk, Catia, Solidworks, etc. Just know that line thickness and their meanings were settled (in Court). You do not need to know about descriptive geometry to understand the origins of 3rd Angle projection vs 1st angle projection, just know that they are there. Likewise, while I am attempting to learn astronomy without clocks or telescopes, that doesn't mean when I want to look at the moon, or Mars, I don't grab a telescope. Same for in the shop. Having used hand tools for construction "I understand why power tools were invented." There is the saying that the user knows enough to accomplish the task at hand, the expert knows all the relevant parts of the subject*; and a scholar knows all that and the rest, too. tschus pyotr *as a one time computer lab rat/monitor/ student assistant, I learned early that a "guru" is just someone with one more trick than you. tschus pyotr -- pyotr filipivich We didn't have these sorts of problems when I was a boy, back when snakes wore shoes and dirt was $2 a pound, if you could find it. We had to make our own from rocks! |

My point: What design tool you use should be dependent upon the type of projects you build, how much detail you need, how dependent you are on machines, jigs and fixtures, and how well you can visualize how things will go together. We are all different in that respect. |

And _appears_ to happen even quicker when the mind and body relaxes... Soooooo moving forward to using a computer.... Drafting, drawing on a drawing board,is wide open to mistakes. You can draw accurately but if you wright the wrong dimension you have a massive problem. You can even mentally interpret how a view should be draw, and not knowingly draw that view wrong too. With manual drawing you have to picture the views, correctly, and then put that on paper. Again, if you do that wrong, the drawing is wrong and that translates to your project being wrong. With a Program such as Sketchup you can draw in 2D or 3D and orbit around the object you have drawn to see the different views. 99.999% of the time if the drawing looks correct, it is correct. You have to use the dimension tool but it fills in the distance. You know exactly at that point if the line you just drew is correct or incorrect in length. And mistakes or design changes are very easily and quickly changed. |

That is a good argument for drawing by hand... you've built the object already in your head so when you move to the shop and materials it's the 2nd time you've built it. |

Recently I've had some home renovation problems present themselves that I spent way to much time thinking about... conjuring up all the ways it could go wrong and myriad alternatives. Then one day I just tackled the problem with complete success all the while asking myself why I just didn't do it sooner! LOL |

We are all different in that respect. But you have the background that is inherent now in whatever you do in those sketches -- without that doing what you do now would not be nearly as effective. Yes, that goes with my point. Also embedded in my point is the notion that we are constrained by our tools. When you use only power tools or are making many copies of a project you are more dependent on exact measurements and exact machine work. When you design and build a piece of furniture with a combination of power and hand tools, and build to fit, fewer exact dimensions are needed. For example I don't worry about making boards exactly .75 inches thick when I prep stock for a one off project. If I'm a little fat or a little thin it doesn't matter. On the other hand, if I were making parts for 100 of those items I really need to get as close to .75 inches as possible. Case in point, while not of solid wood an associate of mine made, as I recall, 175 bathrooms for a motel... He couldn't do that economically unless every part was made to a predictable size. I've got an upcoming renovation project where I'm going to make ash flooring for my house... I'm using a cabinet saw, jointer, thickness planer and shaper for that project and a power feeder. I need efficiency and accuracy and the power feeder facilitates that. Other things to consider in design. I can cut dovetails by hand where the narrow ends of the pin sockets in the tail board are a saw kerf wide. That is not something you can do with a router. I can easily cut compound angles with a handsaw that would be very difficult to accurately make with power tools. I can shave a few thousandths off or alter an angle with a shooting board to attain a perfect fit, something very difficult to do with power tools. Whereas my jointer is 8" and my floor model thickness planer is 13" I can flatten and thickness any width I need to with hand planes. In summery, in the context of how you design, you need to consider your tools and skills. John |

A "decent" dimensioned drawing helps figure these things out - even if it is not "accurately to scale". I'd call it a "dimensioned assembly drawing" with the dimensions and locations of things like dados and rabbets clearly located and dimensioned - edge clearances determined, etc. That doesn't need autocad or a fancy frafting machine but a good scale / ruler etc IS handy - IOW - not just a "sketch" on a napkin or box-top. |

But as you said "decently dimensioned". And when you're the design department and the shop lead, it is easier to just 'wing it'. "Let it flow organically."

I realize that one does not need to know about whatshisnames experiments into latent heat in order to make coffee; nor does one need to does not need to know about Leo Baekeland and his invention in order to in order to use a Kerug pod. Neither are you required to know the role of romantic entanglements which lead to the establishment of British coffee plantations in Jamaica. One simply has to know "Go to the cupboard, get the box!" I mean, is it really necessary to understand how credit in the early 15th century lead to the development of GPS, Cell phones and SpaceX in order to place a call? No. But it is still a cool subject to look into. You make no sense but communication, quite obviously, wasn't your intention. |
