I got this saw new a couple of years ago. I don’t scroll on a regular basis the way many of the members here do. But I decided I’d make another wooden gear clock and thought I should get scrolling practice in before I start. I have a butterfly pattern from one of those magazines.
Anyway here’s my question/issue. The manual clearly states “Upper arm must be parallel (within 1/8”) to the table. If necessary, use the upper arm adjuster to raise or lower the arm as needed.” The upper arm adjuster is the large knob at the rear of the saw.
So I broke a blade today and when I checked for parallel the upper arm was wider, near the blade, than at the rear, by the motor. I turned the knob CCW to “raise” the arm. There was movement of the upper arm and the measurement is nearly correct BUT the knob reached a point where no more adjustment could be made, it was no longer under tension.
So I’m hoping someone can tell me what’s up and what to do. (Note: I have no other issues with the saw. I don’t break a lot of blades, tension always is fine, the arm easily lifts and stays up while threading a blade into the next entry hole.)
I can post a picture but I thought with as many Excalibur owners as there are here it would be a waste.
Thank you for taking time from raking to read about my dilemma.
