A good question for a new owner is does it *require* pin-end blades or does it merely *accept* pin-end blades? Some scrollsaws are exclusively one or the other, while others will work with either. If it will accept either then you may simply need to increase the tension adjustment to take out the slack (although 1/2" would be an awful lot of adjustment).
In some cases, you can purchase adapter kits that will adapt a pin-only scrollsaw to pinless. You will find a much broader array of blades available for pinless models -- and the pinless require much smaller access holes.
I don't use my scrollsaw all that much, but I really love the sanding bands available for scrollsaws for smoothing small interior spaces and cutouts.
