I have been scrolling for several years and dearly love the hobby. I have recently developed a problem that I can't figure out what is causing it. While cutting on thicker wood, 1 1/2", mainly numbers or letters, the piece will not fall thru from either side. I have insured that the table is 90⁰ to the blade. I feel sure that it has something to do with force, but I make a conscious effort not to force the cut but the piece will not easily come out in either direction! Using flying Dutchman #5 SR blade. Any suggestions or recommendations?
