I posted this in a comment to the red tag resolution, but I’m reposting it here separately for emphases:
The DoAll blade cuts very well when it is sharp, but we have been dulling these blades far too fast. Heat greatly accelerates tool wear, so I remind everyone that you must use cutting fluid when cutting steel on the DoAll. You should also use it for thicker plates of aluminum, roughly anything a half inch or thicker. With the hand spray bottles, it would be difficult to use too much cutting fluid, and too much is better than not enough.
Also, while the DoAll does require more effort to push a piece through than most machines, it still shouldn’t require significant exertion. This is not a rapid cutting machine; it should take some time to get through a piece. People are powering pieces rapidly through, which also dulls the blade excessively. Then people are exerting even more force to overcome the dull blade, which creates a downward spiral. Be patient and let the blade do the work. If you are really making no progress with a reasonable force, then report the dull blade to the stewards.
