I think my scroll saw says I can cut up to 2 inches (5cm). But when I've tried to cut oak over an inch, it breaks the blade. Since pine is softer, do you think I could cut 4.5 mm (almost 2 inches)? I have FD blades 5, 7 and 9 ultra reverse. It will just be a 4.5 x 4.5 piece of pine, to make someone some chunky dice! So not a very long sawing distance.
