粗剪

Unless cut by CNC, full-size plywood is unwieldy and must be rough-cut into smaller pieces. For fast and accurate cutting, I created a saw and router cutting guide using MDF and an aluminum angle. One side of this guide is for a hand-held trim saw. 另一面用于便携式刳刨机，用于需要平滑边缘的最终切割,en,切割胶合板之前,en,我用剃须刀在胶合板上划线,en,刻痕距切割导轨八分之一英寸,en,金属尺用于这种偏移，因为它与修剪锯片的宽度相同,en,11 月 4 日,en.

Before cutting plywood, I score the plywood veneer using a razor knife. The score is one-eight of an inch away from the cutting guide. A metal ruler is used for this offset as it is the same width as the trim saw blade.
