�@The width of the baht in "It is blue" sound road part must be all constant.
If the gauge putting of [paneruso-] together is finished by one time for the person who cuts it, this problem is a problem of solving it. However, it should be a drawing in it where the gauge putting of [paneruso-] together ends by one time. If this doesn't actually rewrite the drawing because Nagaoka [tetsuotoko] teacher's initial work doesn't assume cutting with [paneruso-], and have whether to take very a lot of parts with one board in the mind about a large problem, it is difficult to make the length of "Sound road part" constant. However, because accuracy in the economy of the board or [paneruso-katto] is included, it is possible to cut it comparatively accurately in the work at latter term.
The photograph is a board removing of D-37. "Red" is a shroud and "Blue" is an internal sound road part. The gauge putting of [paneruso-] together can be done only once because a blue sound road part is settled and an accurate cutting be expected.
�AThe size of "It is red" shroud is the same as a blue sound road part or it is any more.
This is a problem of happening from there is irregularity in the thickness of the plywood used. There is actually �} about 0.5mm plywood of 15mm and 21mm. It is necessary to change the size of the shroud of the speaker because of the difference of board thickness if going by Nagaoka [tetsuotoko] teacher's removing the board. Because the day grows dark when such ..[demasuga].. ..the numerical value.. a troublesome thing is done if the size is calculated again measuring board thickness with calipers, an unnecessary part adopts the method of saying as cutting down (It is possible to do also with paper) from the one of the shroud in the drawing with the plane later for add about 1mm both ..length and breadth.. more extra me. It introduces this method by the method of saying as being unevenness [hara].
 | It is possible to match it to the same size as "Blue" by being cut down later if the shroud of "Red" is greatly reserved. |
 | There is no correction though it does when the shroud of "Red" is small. |
