Am I allowed to put a small amount of tape on the edge of a piece of cut metal so it will not scrape anything?
Also we made a dial with a potentiometer and a knob with a intake roller to use to switch between programs quickly. would it be legal to cover the front of a section of plate with a layer of masking tape so we can write the tick marks to place the dial?
Also would it be legal to put a small amount of tape on a piece of the non shatterable plastic to better strengthen it at a point where holes were drilled?
