When cutting aluminum parts from a large sheet, this technique is fast and precise for those straight cuts.
Making long, precise cuts in aluminum sheets is a common task for those making their aircraft parts "from scratch". Using hand shears is not practical, it cannot hold a perfectly straight line and the curling of a cut edge cannot be tolerated.
An inexpensive knife (Olfa) can be used to score the aluminum sheet for a straight cut of any length. However, the disadvantage shows up in the large number of knife strokes required to break thru the aluminum. The technique we show in the video uses a bending brake to provide the straight edge for scoring. The brake then separates the aluminum along the score line with only a few strokes of the knife. This really speeds up an otherwise tedious task.
