In another thread we were discussing whether or not blades stretch under normal use. As a beginner I would put excessive of tension on the blade and used to break quite a few.
I tend to wear them out now.
I remember reading the amount of tension on a scrollsaw blade is in the tens of thousands of pounds per square inch. I wish I could remember where I read that. When you think of the cross section of a blade and the leverage involved in the tension mechanism, multiplied by the length of the arm, I guess it isn't too far off.
Now that the long winded preamble is over, how many scrollers leave tension on their saw? I know I do and it is a nasty habit I need to break. Not only does it apply forces to the blade, clamps and arm, it is also hard on bearings and bushings.
I am sure there are other bad habits that some of us have in the scrolling world and we are not even aware they are bad.
I would show you a picture of my shop so you could find them but I am afraid the website couldn't handle all that extra traffic
