Default Changing the RPMs on a 1.2AMP, 120V, 1 phaze 60HZ Motor

Hi looking for some guidance. I am a cabinet maker, woodworker, I am currently designing a small wood moving art project. I have an old King Scroll Saw and would like to use the variable speed motor in this project. Dilemma I have is the controls for the motor have it's slowest speed at 550rpm up to something like 1450rpm. I would like to if possible change the numbers, by that I mean, my slowest speed becomes 0 and as I turn the dial the rpms increase, do not need it anywhere near 1450rpms, so it doesn't really matters here it tops out at, just won't turn the dial that high. Is this possible, and or what might I need to alter the start up speed to zero.

To alter the speed to ZERO, you need to use the OFF/ON switch.
The rest should work with he variable speed controller attached to the unit.
I doubt a scroll saw would last long at a near zero start up speed. You will be breaking blades quickly.
Teacher, my brain is full... Can I go home now?
