Those spiral blades are much thicker than the standard scroll saw blades.
You are going to have to adjust the blade clamps for this difference
(adjusting nut in the side of the clamp if it's the same as my Delta saw),
and you will probably have them pull out of the clamps a couple of times
while you are using them before you figure out just how tight they have to
be adjusted to get them to hold OK. Experience is the best teacher in this
While spiral blades seem like a great idea, I was less than impressed with
the results that I got from them. I gave up and went back to standard blades
because the cut is smoother, I can steer the cutting line better, and the
clamps on my saw (Delta Q3) don't let go of the blade as often.
