How did you go about making the adjustment knob longer? The if I take out the adjustment knob and move the blade w/ my hands it has room to move before the screw which connects the cap iron to the blade bottoms out. There is more threaded rod coming through the knob, and if there was a way to extend the possible travel of that knob I think it would work. I couldn't figure out a good way to adjust that without buggering the threads.
