There are many and this mine- am i the first one to recognize the quote? Do I get the movie nerd prize? That's one of my favorite movies, btw.
As for yourvtension: clean out around the feed dogs and bobbin assembly first, then set the tension. If you are too far toward either end of the tension range on top, it's time to turn the screw on the bottom bobbin 1/8th turn, so you get more towards the middle of the range on the top tension array. I am frequently guilty of giving inexplicably abbreviated directions because I assume a shared base of understanding which does not exist. If I have done this again, please ask for elucidation.
And remember, one is for fun.
