Key Answers, Explanations, Notes, and Concepts

31) Which lumber has been cut tangentially to the growth rings and the fiber runs about 90 degrees to the face? a. Edge-grain b. Angle-grain c. Flat-grain d. Close-grain

Answer: a. Edge-grain

Edge-grain- (or vertical grain) is produced by quarter-sawing the lumber so that the edges of the growth rings are exposed on the widest faces of the piece, and the rings form angles of 45 to 90 degrees with the widest faces.
Flat-grain-

Close-grain- Open-grained and close-grained wood refers to the size of the pores; woods with large visible pores are 'open-grain', and those with pores too small to see clearly are 'closed-grain'. When the wood's sawn, large pores can split and this will decide whether timber needs a filler to achieve a smoother finish.

Drafting Notes

  Resource: PNU- TLE Drafting Concept of Drafting  In most cases before making the final plan it takes the form of sketches and drawing  Sketches usually precede the making of scale drawing of an object.  An attempt to make something without having a definite plan usually results in waste of materials and time as well as in a poorly constructed project. DRAFTING EQUIPMENT In order to do planning or drafting work it is first necessary to learn the names of the tools the draftsman uses and the way he uses them to produce a good drawing. In addition it is necessary to learn certain rules and regulations which are the principles of good drafting.  Drawing Pencils - Drawing pencils is made of a much better grade of graphite, commonly called lead, than the ordinary writing pencils so it is possible to draw lines which are of uniform blackness and to do better quality of line work. - The hardest of the drawing pencils is the 9H. The next hardest in order are the 8H, 7h, 6H, 5H, 4H, 3H, 2H
