When you push can you make it softer like a coil? I don't mean by slowing it down. Is the a spring that makes the stroke of the needle shorter when you push? Does this make sense?
From looking at the photos, I don't think so, Owlsden. Unless there is a soft piece of silicone (like how some members altered their stealth machines) in the eye of the - I'm not sure what to call the bar that connects the armature bar with the cam - you know what I'm talking about by process of elimination. On the stealth, people were drilling out the hole at the top to be a little bigger, slipping some soft silicone tubing in there (though some were just drilling the hole out to be a little more oval to give it some slip), and then reattaching the a-bar. It's hard to tell from the photos of these machines, but they appear pretty straight-forward and basic. The amount of torque on the motor may be your only 'give' with these machines. (I could be wrong, but that's how it appears to me)
